A Statement of Solidarity from Princeton Hydro

 

We stand with you. Black Lives Matter.

George Floyd’s murder by police officers has shaken us, like the rest of the world. This week, as we try to keep working to improve our ecosystems, quality of life, and communities, what’s been forefront in our minds has been the river of blood from a history of injustice to the Black community. 

For far too long, the Black community has been wrongfully targeted by the institutions that are supposed to protect them. And for far too long, a segment of society that is privileged enough to look away, has turned a blind eye to systemic racism. This cannot continue. We are proud to see people of all backgrounds coming together to display their anger and frustration. We support demands for greater institutional and societal changes that are essential to ending extradjudicial murder like what happened with Mr. Floyd, Breonna Taylor, Ahmaud Arbery, and countless others. However, we must not only look to others to enact change. Each of us must look internally.

At Princeton Hydro, our deep-seated, shared motivator, which we call our “why” statement (right), drives us to make the world a better place everyday. We stand with our clients and allies, like American Rivers, who believes that “fighting for rivers means fighting for justice” and National Audubon Society who understands that “the outdoors – and the joy of birds – should be safe and welcoming for all people.” We believe in positive change, both for our environment and for our people. 

It is important that we reflect internally to understand how we can improve our small business and live up to our core value of a “positive working environment” for all. Princeton Hydro’s Justice, Equity, Diversity, and Inclusion (JEDI) Steering Committee, an internal team of scientists, engineers, and administrators, suggested that we deem Martin Luther King, Jr. Day an official Day of Service for staff, and we listened. 

So, Princeton Hydro is changing our company policy to observe MLK Day as a “Day of Service,” which will allow for employees to choose to spend the day volunteering instead of coming into work. We believe this small change is important to celebrate the civil rights leader’s legacy and to continue to give back to our local communities. Since Princeton Hydro’s inception, we have been committed to serving our communities each and every day. We remain devoted to this goal, as it is an integral part of our day-to-day operations.

The JEDI Steering Committee was founded to promote diversity and inclusion within Princeton Hydro. We recognize that our offices and our industry are underrepresented with people of color, creating an inaccurate representation of our society as a whole. Prejudice goes far beyond our government institutions, and the first step to solving any problem is acknowledging it exists. We acknowledge that we are all guilty of unconscious bias in our homes, our schools, and our workplaces. That is why we, as professionals who have the privilege of working in the fields of science and engineering, are continually educating ourselves on how to honor our responsibilities in making our profession welcoming and obtainable for people of all backgrounds. 

We cannot afford to cover our ears and close our minds. We believe that each and every one of us has work to do to fight racism and promote justice.  People from all backgrounds have now taken to the streets to demand reform within policy agencies around the country. That is why our small business has committed to donating to organizations that are on the ground fighting for justice and equality, as well as planning sustainable and resilient communities for the most vulnerable people. 

During the month of June, we will be matching employee donations, up to a total of $1,000, for the following nonprofits, and we hope you will consider donating as well:

We recognize that this is only a first step toward actively working to dismantle these very deep rooted, unjust systems. We urge you to take a first step too, whether that be donating, volunteering, voting, signing petitions, etc. It is always the time to act, but this time, we have no choice. We cannot successfully do good for our planet, our shared home, without valuing and protecting its people. All people. 

We look forward to building a better future for our people and for our planet, together.

Yours in the movement,

Princeton Hydro

Analyzing Mitigation Strategies for Flood-Prone Philadelphia Community

Hydrology is the study of the properties, distribution, and effects of water on the Earth’s surface, in the soil and underlying rocks, and in the atmosphere. The hydrologic cycle includes all of the ways in which water cycles from land to the atmosphere and back. Hydrologists study natural water-related events such as drought, rainfall, stormwater runoff, and floods, as well as how to predict and manage such events. On the application side, hydrology provides basic laws, equations, algorithms, procedures, and modeling of these events.

Hydraulics is the study of the mechanical behavior of water in physical systems. In engineering terms, hydraulics is the analysis of how surface and subsurface waters move from one point to the next, such as calculating the depth of flow in a pipe or open channel. Hydraulic analysis is used to evaluate flow in rivers, streams, stormwater management networks, sewers, and much more.

Combined hydrologic and hydraulic data, tools, and models are used for analyzing the impacts that waterflow – precipitation, stormwater, floods, and severe storms – will have on the existing infrastructure. This information is also used to make future land-use decisions and improvements that will work within the constraints of the hydrologic cycle and won’t exacerbate flooding or cause water quality impairment.

Simply put, hydrologic and hydraulic modeling is an essential component of any effective flood risk management plan.

Putting Hydrologic & Hydraulic Analysis to Work in Philadelphia

Eastwick, a low-lying urbanized neighborhood in Southwest Philadelphia, is located in the Schuylkill River Watershed and is almost completely surrounded by water: The Cobbs and Darby creeks to the west, the Delaware River and wetlands to the south, and the Schuylkill River and Mingo Creek to the east. The community is at continual risk of both riverine and coastal flooding, and faces an uncertain future due to sea level rise and riverine flooding exacerbated by climate change.

Princeton Hydro, along with project partners KeystoneConservation and University of Pennsylvania, conducted an analysis of Eastwick, the flood impacts created by the Lower Darby Creek, and the viability of several potential flood mitigation strategies.

Flood mitigation approaches can be structural and nonstructural. Structural mitigation techniques focus on reconstructing landscapes, including building floodwalls/seawalls and installing floodgates/levees. Nonstructural measures work to reduce damage by removing people and property out of risk areas, including zoning, elevating structures, and conducting property buyouts.

For Eastwick, studying stream dynamics is a key component to determining what type of flood mitigation strategies will yield the most success, as well as identifying the approaches that don’t work for this unique area.

Princeton Hydro Senior Ecologist Christiana Pollack CFM, GISP participated in a workshop for Eastwick residents held by CCRUN and the Lower Darby Creek team. The goal of the workshop was to get the community’s input on the accuracy of the predictive models.Princeton Hydro’s study focused on the key problem areas in Eastwick: the confluence of Darby Creek and Cobbs Creek; a constriction at Hook Road and 84th Street; and the Clearview Landfill, which is part of the Lower Darby Creek Superfund site. Additionally, the study sought to answer questions commonly asked by community members related to flooding conditions, with the main question being: What impact does the landfill have on area flooding?

The built-up landfill is actually much higher than the stream bed, which creates a major disconnection between the floodplain and the stream channel. If the landfill didn’t exist, would the community still be at risk? If we increased the floodplain into the landfill, would that reduce neighborhood flooding?

Princeton Hydro set out to answer these questions by developing riverine flooding models primarily using data from US Army Corps of Engineers (USACE), Federal Emergency Management Agency (FEMA), The National Oceanic and Atmospheric Administration (NOAA), and NOAA’s National Weather Service (NWS). FEMA looks at the impacts of 1% storms that are primarily caused by precipitation events as well as coastal storms and storm surge. NOAA looks at the impacts of hurricanes. And, NOAA’s NWS estimates sea, lake and overland storm surge heights from hurricanes.

This is an example of a 2D model showing where the water is originating, how the water flows through the neighborhood, moves to the lower elevations, and eventually sits.

This is an example of a 2D model showing where the water is originating, how the water flows through the neighborhood, moves to the lower elevations, and eventually sits.

The models used 2D animation to show how the water flows in various scenarios, putting long-held assumptions to the test.

The models looked at several different strategies, including the complete removal of the Clearview Landfill, which many people anticipated would be the silver bullet to the area’s flooding. The modeling revealed, however, that those long-held assumptions were invalid. Although the landfill removal completely alters the flood dynamics, the neighborhood would still flood even if the landfill weren’t there. Additionally, the modeling showed that the landfill is actually acting as a levee for a large portion of the Eastwick community.

This model was developed to illustrate how the removal of the landfill impacts waterflow through the Eastwick community.

This model was developed to illustrate how the removal of the landfill impacts waterflow through the Eastwick community.

Ultimately, the research and modeling helped conclude that for the specific scenarios we studied, altering stream dynamics – a non-structural measure – is not a viable flood mitigation strategy.

The USACE is currently undergoing a study in collaboration with the Philadelphia Water Department to test the feasibility of a levee system (a structural control measure), which would protect the Eastwick community by diverting the flood water. Funding for the study is expected to be approved in the coming year.

Take a Deeper Look at Eastwick Flood Mitigation Efforts

There are many studies highlighting flood mitigation strategies, environmental justice, and climate change vulnerability in Eastwick. Princeton Hydro Senior Project Manager and Senior Ecologist, Christiana Pollack CFM, GISP, presented on the flooding in Eastwick at the Consortium for Climate Risk in the Urban Northeast Seminar held at Drexel University. The seminar also featured presentations from Michael Nairn of the University of Pennsylvania Urban Studies Department, Ashley DiCaro of Interface Studios, and Dr. Philip Orton of Stevens Institute of Technology.

NJDEP Releases Updated Guidance for Harmful Algal Blooms

Last summer, 39 of New Jersey’s lakes were plagued with toxic algae outbreaks, also known as harmful algae blooms or HABs, causing major water quality degradation, beach closures and health advisories. In response, the NJDEP implemented a unified statewide approach to addressing HABs in freshwater recreational waters and sources of drinking water, and protecting the public from risks associated with exposure to cyanobacteria.

Last week, NJDEP announced a new component to its statewide Cyanobacterial HAB Response Strategy: a color-coded health alert index that provides precise recreational use recommendations for impacted waterbodies based on levels of cyanobacteria and/or cyanotoxins present. The index has six tiers – NONE, WATCH, ALERT, ADVISORY, WARNING, and DANGER – each providing recommendations on the specific activities that should or should not be pursued based on water monitoring results.

“Princeton Hydro is proud to be one of the contributing factors in the development of the Updated Guidance for HABs,” said said Dr. Fred Lubnow, Director of Aquatic Resources for Princeton Hydro. “We feel this updated protocol will provide the necessary and objective information for State and local organizations to make informed and rational decisions, based on sound and scientifically-based data, on how to deal with HABs in a recreational setting.

Princeton Hydro and Clean Water Consulting are the technical advisers for the New Jersey Lake Group, who have met a number of times over the last 8 to 9 months to discuss the State’s guidance on dealing with HABs.  In late 2019, on behalf of the New Jersey Lake Group, Princeton Hydro and Clean Water Consulting developed a White Paper providing recommended changes for consideration to NJDEP’s Recreational Response Strategy to HABs.

“I’m proud to say that many of the provided recommendations were integrated into NJDEP’s Updated Guidance for HABs,” explained Dr. Lubnow.

WATCH
(Suspected or confirmed HAB with potential for allergenic and irritative health effects)
This warning will be posted when HAB cell counts exceed 20,000. In this scenario, public beaches remain open, but the index instructs the public to use caution, provides information on the potential less serious health effects, and allows for more informed decision-making.

ALERT
(Confirmed HAB that requires greater observation due to increasing potential for toxin production)
This warning indicates a public bathing beach closure only and is posted when a HAB has been confirmed with cell counts between 40,000 and 80,000 and no known toxins above the public threshold. Beaches remain open (dependent upon local health authority) and monitoring for future toxin production should be increased.

ADVISORY
(Confirmed HAB with moderate risk of adverse health effects and increased potential for toxins above public health thresholds)
Signs will be posted for this warning level when cell counts exceed 80,000 or when toxin levels exceed 3 micrograms per milliliter of microcystins. Public bathing beaches will be closed, but the waterbody will remain accessible to some “secondary contact” activities, like boating.

WARNING and DANGER
(Confirmed HAB with high risk of adverse health effects due to high toxin levels)
and (Confirmed HAB with very high risk of adverse health effects due to high toxin levels)
These tiers are designed to alert the public to the presence of HABs that are producing very high levels of toxins which justify additional caution. In some instances, the entire waterbody may be closed for all public use. New Jersey has experienced approximately 12 “warning level” HAB events over the last 3 years; monitoring has never indicated a “danger level” HAB event.

According to their press release, NJDEP is committed to working with local officials to implement the index and get signage posted at lakes throughout the state as soon as possible.

In order to create the health index, NJDEP scientists carefully reviewed HABs data collected over the last three years by Lake Hopatcong Commission, Lake Hopatcong Foundation, Princeton Hydro, and other sources. The tiered warning system will enable lake communities, residents and visitors to make more individualized decisions about what risks they are willing to take and what activities they feel comfortable engaging in at the various levels of HABs.

In the coming days, the NJDEP’s Harmful Algal Bloom website will be updated to include the new health index and accompanying signage, relevant monitoring data, and other information for each of the impacted bodies of water, as well as an updated HAB Monitoring and Response Strategy. For now, you can read the full press release and additional information here: https://www.nj.gov/dep/newsrel/2020/20_0023.htm.

Identifying, Understanding and Addressing Harmful Algae Blooms

Volunteer Spotlight: Monitoring Baby Bird Boxes & Counting Shorebirds

We’re excited to put the spotlight on Princeton Hydro Environmental Scientist Emily Bjorhus and her admirable volunteer work.

As an Environmental Scientist, Emily Bjorhus works on a wide range of projects from flood risk management to wetland mitigation to stream restoration. She specializes in wetland and stream ecology and environmental permitting and compliance. Outside of the office, Emily is an active volunteer with Natural Lands and the Delaware Shorebird Project, working to protect natural resources, promote biodiversity, and protect important species. Emily also volunteers at Franklin Delano Roosevelt High School in Brooklyn, NY teaching Environmental Science students about wetlands. We’ve put together a snapshot of Emily’s volunteer activities:

Natural Lands – Force of Nature Volunteer

Natural Lands is a nonprofit organization that saves open space, cares for nature, and connects people to the outdoors in eastern Pennsylvania and southern New Jersey. Founded in the early 1950s, today nearly five million people live within five miles of lands under Natural Lands’ permanent protection.

As a Force of Nature volunteer with Natural Lands, Emily has been monitoring ~20 nest boxes located in meadow and forest edge habitat at Gwynedd Preserve since 2018. From April through mid-August, Emily and another volunteer visit the sites every 5-7 days to monitor the nest boxes for the types of species using the boxes, nest condition, nest materials, number of eggs laid, number of eggs that hatch, and number of chicks that fledge. Chickadees, wrens, blue birds, and tree swallows are the primary species that nest in the boxes Emily monitors.

When asked what she loves most about this volunteer work, Emily said, “I love watching how the birds build their nest week after week, seeing the eggs multiply and tracking the chicks’ growth. I even enjoy dodging dive-bombing tree swallows.”

Delaware Shorebird Project – Data Collection Volunteer

Delaware Shorebird Project is led by DNREC’s Division of Fish & Wildlife in partnership with the U.S. Fish and Wildlife Service, Delaware Museum of Natural History, British Trust for Ornithology and Wash Wader Ringing Group, with the help of experienced and dedicated volunteers like Emily.

The project monitors the health and status of migratory shorebird populations to collect data that can be applied to the conservation of these birds. The research has resulted in better understanding of the ecology of shorebirds migrating through Delaware Bay, management of the horseshoe crab harvest to sustain the shorebirds’ population, and protection of key shorebird habitat.

Emily participated in a 3-day shorebird monitoring initiative, which included counting the number of shorebirds on the beach, re-sighting birds previously marked with leg flags, participating in bird catches, and weighing and measuring birds from the catches. The data collected helps monitor trends in shorebird abundance, migratory routes, condition and other important biological data.

“It’s such a pleasure working with the amazing people that come from all over the world to run and participate in this ambitious study,” said Emily. “The data collected from this program will hopefully aid researchers and policy makers to develop strategies to better protect shorebird habitat in the future.”

Franklin Delano Roosevelt High School Environmental Studies – Guest Speaker

Ms. Hannah Goldstein and her Environmental Science students at Franklin Delano Roosevelt High School in Brooklyn, NY welcome Emily as a volunteer guest speaker to teach all about wetlands. The instruction also includes a hands-on session where students collect soil samples to determine if hydric soils are present and identify surrounding trees using a dichotomous key.

“Science is such an important subject matter for kids to be learning for a variety of reasons. Environmental science education in particular encourages thought patterns, which get kids engaged in real-world environmental protection activities,” said Emily. “I really enjoy working with Ms. Goldstein and her students. I hope my presentation inspires the students to learn more about wetlands and become ambassadors of wetland conservation.”

 

Emily earned her M.S. in Sustainable Engineering at Villanova University and holds a B.S. in Environmental Science from University of Colorado at Boulder. As an Environmental Scientist for Princeton Hydro, she coordinates, leads and assists with state environmental permitting programs and NEPA compliance and documentation, including preparation of Federal and state permit applications, Endangered Species Act 7 consultations, and Federal Energy Regulatory Commission (FERC) environmental review processes. In addition, she conducts a variety of environmental field investigations such as wetland and waterbody delineations.

We’re so proud to have Emily on our team and truly value the work she does inside and outside the office.

Live Your “Why”: A Special Message from Princeton Hydro’s President

Friends of Princeton Hydro,

Welcome, Spring! As the sun shines through the window of my “remote office,” for a moment, I am able to set aside the pandemonium that the COVID-19 outbreak has caused, and feel the warmth of the season changing. As the native wildflowers emerge and spring migrants return, we are reminded that the environment persists on, even when society comes to a halt.

We, at Princeton Hydro, are heartbroken to see small businesses and nonprofits struggling to keep their doors open and operations running. As more “stay-at-home” and “non-essential closure” orders are issued across the Mid-Atlantic and New England states, I consider us lucky. As a professional service-based business, our firm performs engineering designs and scientific analyses, a majority of which can be conducted remotely. And, with offices spread across the Northeast, we were prepared for this moment, as we rely upon remote collaboration between offices on a daily basis.

But, it takes more than just having the technology at our fingertips. What enables success even more than working laptops and VPN connections is a motivated and dedicated staff. The people at Princeton Hydro live our mission and core values. They are determined to serve our clients and keep us open, and are the reason why I love going to work everyday. Our deep-seated, shared motivator, which we call our “why” statement, drives our productivity and engagement: “We are committed to changing our ecosystems, quality of life, and communities for the better.”

For those who are not familiar, a “why” statement is the most basic and elemental reason for “how” and “what” we do. Simon Sinek, the author of Start with Why, defines “why” as the firm’s purpose or belief. As Sinek states, most companies start with “what they do” and “how they do it” and very few can clearly articulate “why” they do what they do. Defining your “why” allows people to feel connected, like we belong to something bigger, because it aligns with our own values and beliefs.

We believe that starting with “why” enables Princeton Hydro to connect with our clients, hire the right staff, and build partnerships founded in our shared mission and values. It is that short and simple sentence which drives each and every person at Princeton Hydro to do the best they can, not only to meet client needs, but to ensure that we are making a positive impact on those around us, even during these trying times. Not being able to walk up and say “hello” and ask how our people are doing in-person has necessitated our need to communicate even more regularly than we would have.

With the transition to remote working, we got creative in maintaining intimate communication and connection. About one month ago, we instituted internal “Daily Connection” video calls to brief our staff on government executive order changes, employee benefit options, fieldwork safety protocols, and workflow updates. We’ve shifted to using Google Hangouts for most of our regular meetings. We use interactive tools, such as Mentimeter™, to engage 40-50 employees on our daily check-ins. And, each Friday, we’re hosting virtual, themed Happy Hours to unwind and share stories over cocktails. While these virtual events have become the temporary norm, we may opt to integrate these newfound ways of connecting upon return to our in-office lifestyle. Afterall, “returning to normal” is a misnomer, as this worldwide pandemic has forever changed the way we operate moving forward.

Nonetheless, there is a positive twist to all of this. Previously, I did not take the opportunity to see, chat, and check-in with the entire staff on a day-to-day basis. However, working remotely has provided me with the luxury of talking to all of our people, whether over email, text, direct message, phone, and/or video chat.

And, while I joke about not knowing what day it is and being stuck at home, I’ve been able to spend quality time with my wife Amy, our two boys, and our rambunctious hound Blue, making sure to take breaks to laugh with them about the conundrum we are in. I’ve also caught up with extended family and close friends, where in “normal times” we make the excuse of being simply too busy. This unexpected mandatory remote lifestyle has enabled us to develop a deeper connection with each other and spend more time with our families. This is clearly the silver lining to the state of our world at this time.

We do recognize that there are people struggling to make ends meet and those who are suffering from this terrible virus. Whether it be a neighbor, local business, or acquaintance, together, we must find the strength to support those who are in need. Whether it be helping a friend, ordering takeout from local restaurants, or donating funds to relief efforts, let’s come together (virtually) to give back to the community. And, let us be reminded to take the time to enjoy the little things we usually take for granted.

In closing, I encourage you to live your “why.” Use this time to make a positive difference, appreciate what you have, make the best of this situation, and, most importantly, help those who need it.

With gratitude to all,

Geoffrey M. Goll, P.E.
President
Princeton Hydro

Get your Yard Spring-Ready

Residential homes and neighborhoods can benefit from the implementation of green infrastructure in more ways than many people realize. Planting native flower beds reduces runoff and attracts important pollinators.

  • Reduce Invasives, Plant Natives: Tulips will soon be emerging from the ground, buds blossoming on trees and, unfortunately, invasive plant species will too begin their annual growing cycle. Invasive species create major impacts on ecosystems near and far, but we can all do our part to reduce the spread. To learn more about aquatic invasive species and how to address them, check out our blog.

Be Water-Wise

Now that we’re all spending more time at home, this is a great opportunity to incorporate better water-conservation practices into our daily lives.

  • Reduce water waste by checking for leaks that have been caused by winter freeze. Check garden hose spigots and sprinklers, and replace valves, washers and other components as necessary.

  • Install a rain barrel and use the captured rainfall to irrigate flower beds. This is another fun and inexpensive way to reduce runoff and save water. You can order a rain barrel online or search online for DIY rain barrel ideas. Remember to cover your barrels to keep mosquitoes at bay.

Let’s Talk Toilets

According to the USEPA, toilets account for more water use than any other water-consuming product in your home. Toilets are estimated to be responsible for upwards of 30% of household water consumption. Additionally, flushing anything besides toilet paper has major negative impacts on the environment.

  • Eliminate toilet leaks: 79% of water lost in the home is through toilet leaks. Often silent, these leaks can waste up to 300 gallons of water per day. Check for leaks using food coloring. Replace the refill valve or flush valve when necessary.

  • Flush Responsibly: NY State Department of Environmental Conservation recently issued an email requesting more responsible flushing habits. As a reminder, disinfectant wipes, diapers, baby wipes, personal hygiene products, and any paper products other than toilet paper should never be flushed! These materials create significant damage to sewer systems, water treatment plants, and septic systems. Learn more.

Bloomfield: Restoration Efforts Transforming Industrial Site Into Thriving Public Park

A densely developed, flood-prone, former industrial site in Bloomfield, New Jersey is being transformed into a thriving public park and 4.2 acres of wetlands. This is thanks to the Third River Floodplain Wetland Enhancement Project, which broke ground in March of 2019. The project will restore valuable ecological functions and natural floodplain connection, enhance aquatic and wildlife habitat, and increase flood storage capacity for urban stormwater runoff.

The project team has already made tremendous progress at the site, which is located along the Third River and Spring Brook, two freshwater tributaries of the Passaic River. Princeton Hydro is serving as the ecological engineer to Bloomfield Township; our scientists and engineers have assisted in obtaining grants, collected background ecological data through field sampling and surveying, created a water budget, completed all necessary permitting, designed both the conceptual and final restoration plans, and continues to conduct construction oversight during the implementation of this important urban wetland creation project.

The project team recently utilized a drone to document the significant progress being made:

Over 500 trees and shrubs have been planted in the new wetland with additional trees and shrubs planted along Lion Gate Drive and in existing woodlands. The selected native plant species all provide important wildlife value, including providing food and shelter for migratory birds. Enviroscapes was contracted to install all of the trees and wetland plants at this site and has nearly finished planting efforts:

Removing invasive species and replacing them with native plants, shrubs and trees sets the stage for a flourishing native plant community year after year.

Understanding and Addressing Invasive Species

Spring is officially here! Tulips will soon be emerging from the ground, buds blossoming on trees and, unfortunately, invasive plant species will begin their annual growing cycle. No type of habitat or region of the globe is immune to the threat of invasive species (“invasives”). Invasives create major impacts on ecosystems throughout the world, and freshwater ecosystems and estuaries are especially vulnerable because the establishment of such species in these habitats is difficult to contain and reverse.

This blog provides an introduction to invasive aquatic species, including information that will help you prevent the spread of invasives in the waterways of your community.

Defining Invasive Species

Invasive species can be defined as non-native occurring in an ecosystem that is outside its actual natural or native distributional range. Although the colonization of an ecosystem by non-native species can occur naturally, it is more often a function of human intervention, both deliberate and accidental. For aquatic ecosystems some species have become established as a result of the aquarium trade, fish culture practices and/or transport of plants and animals in the bilge and ballast water of trans-oceanic shipping vessels.

One of the primary reasons invasives are able to thrive, spread rapidly, and outcompete native species is that the environmental checks and predators that control these species in their natural settings are lacking in the ecosystems and habitat in which they become introduced. The subsequent damages they cause occur on many ecological levels including competition for food or habitat (feeding, refuge and/or spawning), direct predation and consumption of native species, introduction of disease or parasites, and other forms of disruption that lead to the replacement of the native species with the invasive species. As a result, invasives very often cause serious harm to the environment, the economy, and even human health. A prominent example is the Emerald Ash Borer, a non-native, invasive beetle that is responsible for the widespread death of ash trees.

As noted above, there are a large number of aquatic invasive species. Some of the more commonly occurring non-native aquatic plant species that impact East Coast lakes, ponds and reservoirs include:

Understanding How Invasives Spread

Either intentionally or unintentionally, people have helped spread invasives around the globe. This is not a recent phenomenon but rather something that has been occurring for centuries. “Intentional introductions,” the deliberate transfer of nuisance species into a new environment, can involve a person pouring their home aquarium into a lake or deliberate actions intended to improve the conditions for various human activities, for example, in agriculture, or to achieve aesthetics not naturally available.

A high-profile example is the introduction of zebra mussels to North America. Native to Central Asia and parts of Europe, zebra mussels accidentally arrived in the Great Lakes and Hudson River via cargo ships traveling between the regions. The occurrence, density, and distribution of Zebra mussels occurred at an alarming rate, with the species spreading to 20 states in the United States and to Ontario and Quebec in Canada. Due to their reproductive fecundity and filter-feeding ability, they are considered the most devastating aquatic invasive species to invade North American fresh waters. They alter and diminish the plankton communities of the lakes that they colonize leading to a number of cascading trophic impacts that have especially negative consequences on fisheries. Zebra mussel infestations have also been linked to increased cyanobacteria (bluegreen algae) blooms and the occurrence of harmful algae blooms (HABs) that impact drinking water quality, recreational use, and the health of humans, pets, and livestock.

Additionally, higher than average temperatures and changes in rain and snow patterns caused by climate change further enable some invasive plant species to move into new areas. This is exemplified by the increased northly spread of hydrilla (Hydrilla verticillate), a tropical invasive plant species that has migrated since its introduction in Florida in the 1950s to lakes, rivers, and reservoirs throughout the U.S.

Regardless of how any of these invasive species first became established, the thousands of terrestrial and aquatic invasive species introduced into the U.S. have caused major ecological, recreational and economic impacts.

Measuring the Impacts of Invasives

After habitat loss, invasive, non-native species are the second largest threat to biodiversity. According to The Nature Conservancy, “Invasive species have contributed directly to the decline of 42% of the threatened and endangered species in the United States. The annual cost to the nation’s economy is estimated at $120 billion a year, with over 100 million acres (an area roughly the size of California) suffering from invasive plant infestations. Invasive species are a global problem — with the annual cost of impacts and control efforts equaling 5% of the world’s economy.”

Of the $120 billion, about $100 million per year is spent on aquatic invasive plant control to address such deleterious issues as:

  • Human health (West Nile Virus, Zika Virus)
  • Water quality impacts (Canada geese)
  • Potable water supplies (Zebra mussel)
  • Commercial fisheries (Snake head, lamprey, Eurasian ruffe, round goby)
  • Recreational activities (Eurasian watermilfoil, water chestnut, hydrilla)
  • Biodiversity (Purple loosestrife, common reed, Japanese knotweed)

Invasive species can change the food web in an ecosystem by destroying or replacing native food sources. As the National Wildlife Federation explains, “The invasive species may provide little to no food value for native wildlife. Invasive species can also alter the abundance or diversity of species that are important habitat for native wildlife. Additionally, some invasive species are capable of changing the conditions in an ecosystem, such as changing soil chemistry…”

Addressing Invasives

Our native biodiversity is an irreplaceable and valuable treasure. Through a combination of prevention, early detection, eradication, restoration, research and outreach, we can help protect our native heritage from damage by invasive species.

What Can We Do?

  • Reduce the spread
  • Routinely monitor
  • Document and report
  • Spread the word

Reducing the Spread:
The best way to fight invasive species is to prevent them from occurring in the first place. There are a variety of simple things each of us can do to help stop the introduction and spread of invasives.

  • Plant native plants on your property and remove any invasive plants. Before you plant anything, verify with your local nursery and check out this online resource for help in identifying invasive plants.
  • Thoroughly wash your gear and watercraft before and after your trip. Invasives come in many forms – plants, fungi and animals – and even those of microscopic size can cause major damage.
  • Don’t release aquarium fish and plants, live bait or other exotic animals into the wild. If you plan to own an exotic pet, do your research to make sure you can commit to looking after it. Look into alternatives to live bait.

Monitoring:
The Lake Hopatcong Foundation Water Chestnut prevention brochureInvasive plant monitoring is one of the most valuable site­-level activities people can support. Contact your local watershed organizations to inquire about watershed monitoring volunteer opportunities. For example, the Lake Hopatcong “Water Scouts” program was established to seek out and remove any instances of the invasive water chestnut species.

If you are a lake or watershed manager, the best way to begin an invasive plant monitoring project is with an expert invasive plant survey to determine which invasives are most likely to be problematic in your watershed and identify the watershed’s most vulnerable areas. Contact us to learn more.

 

Documenting and Reporting:
It’s important to learn to identify invasive species in your area and report any sightings to your county extension agent or local land manager. For example, in New Jersey there is the Invasive Species Strike Team that tracks the spread of terrestrial and aquatic invasives and works with local communities in the management of these species. Additionally, consider developing a stewardship plan for your community to help preserve its natural resources. Princeton Hydro’s team of natural resource scientists can help you get the ball rolling by preparing stewardship plans focused on controlling invasive species and protecting the long-term health of open spaces, forests habitats, wetlands, and water-quality in your community.

Spreading the word:
Many people still don’t understand the serious implications of invasive species. Education is a crucial step in stopping the spread of invasives, which is why it’s so important to talk with your neighbors, friends and family about the hazards and ecological/economic impacts of invasive species.

Also consider talking with your community lake or watershed manager about hosting an educational workshop where experts can share their knowledge about invasives specific to your area and how best to address them. Princeton Hydro’s Director of Aquatic Programs Dr. Fred Lubnow recently gave a presentation to the Lake Hopatcong Foundation titled, “Invasive Species in Watershed Management.” View it here.

 

We encourage you to share this article and spread your invasive species knowledge so that together we can help stop the introduction and spread of invasive species.
