We're pleased to share the following article, originally written by Sean Leslie, Senior Manager of Content and Marketing at Cultivo, and republished with permission. Princeton Hydro and Cultivo recently collaborated in Southwest Montana to assess vegetation, wildlife, and other indicators of ecosystem health as part of a broader biodiversity monitoring initiative for a grassland restoration project. The blog offers an inside look at the monitoring methods used to establish a biodiversity baseline, highlights several unique species encountered during fieldwork, and examines the role of biodiversity and collaborative monitoring in supporting resilient landscapes and successful conservation outcomes.
When we think about nature-based solutions, carbon sequestration often steals the spotlight. But carbon is only one part of a much larger story.
At Cultivo, we believe that restoring grasslands goes far beyond storing carbon underground; it’s about rebuilding complete, living ecosystems. True regenerative progress is measured in on-the-ground ecological health, and one vital metric of that health is biodiversity. Ecosystems rich in plant, bird, and insect life are proven to be more productive, more resilient, and better equipped to thrive.
And just as we do when measuring and verifying sequestered carbon, to ensure our projects deliver measurable, lasting benefits in terms of biodiversity, we’re not relying on satellite images or computer models; we’re putting boots on the ground.
Case in point: Cultivo’s Ecological Impact Senior Manager, Emiline Koopman, recently completed an intensive field visit to one of our partner sites in beautiful Southwest Montana. Alongside the expert field team at Princeton Hydro, she implemented our Biodiversity and Ecosystem Services (BES) monitoring framework across the landscape.
Virtual meetings and digital mapping are great for planning, but nothing replaces walking the land. And during the early summer pilot sampling campaign, Cultivo and Princeton Hydro did exactly that, deploying a full suite of monitoring techniques:
To monitor avian diversity, small weatherproof audio recording devices called Acoustic Recording Units (ARUs) are placed across the property to capture the natural soundscape – including bird calls – continuously over the summer breeding season. At the same time, ornithologists perform human “point counts” by standing quietly in one place for set time intervals with binoculars and clipboards to visually and auditorily record every species seen or heard. Together, these techniques provide a picture of species presence, relative abundance, and spatial distribution, acting as an indicator of overall habitat health.
Measuring plant health and structure, requires laying long measuring tapes across the ground through a specific habitat type and placing square frames (quadrats) at fixed increments along the line. Along this path, researchers systematically count live and dead woody plant stems, measure canopy gaps, and catalog every plant species inside the quadrats, providing detailed ground-level data on plant species richness, ground cover, and pasture resilience.
Insect populations are tracked and measured with Malaise traps, which resemble small, open-sided mesh tents with a collection jar at the top. Flying insects naturally bump into the traps’ fabric walls, fly upward, and are gathered for identification using conventional and eDNA metabarcoding techniques. To complement this, researchers also sit quietly near blooming native plants for timed intervals to perform insect flower visitation counts, tracking specific pollinators including bees, ants, and wasps.
One of the greatest rewards of field work is seeing firsthand what we are working so hard to protect. In Southern Montana, the team encountered an incredible array of flora and fauna.
Here are a few of the standout species that call this ecosystem home, with pictures taken during the recent field visit:
On the high-elevation rangelands of Southwestern Montana, small native plants punch well above their weight. Among them, Spearleaf stonecrop (Sedum lanceolatum) is a tough, fleshy succulent that thrives in the rocky soils of our intermontane sagebrush valleys.
It also happens to be the exclusive host plant for the Rocky Mountain parnassian (Parnassius smintheus), a high-altitude cousin in the swallowtail family. Female parnassians lay their eggs right next to stonecrop patches so hungry spring caterpillars can feed on the leaves. As they eat, the larvae absorb bitter chemicals from the plant, making both the caterpillars and the red-spotted adult butterflies completely unpalatable to birds, a classic example of the invisible, delicate connections that make these high-desert ecosystems work.
If any bird defines the vast sagebrush country of Southwestern Montana, it’s the Brewer’s sparrow (Spizella breweri). This small, inconspicuously plumaged songbird is intricately tied to healthy, intact rangelands.
Brewer’s sparrows are sagebrush obligates, meaning they rely almost entirely on big sagebrush ecosystems for nesting, shelter, and feeding on insects and seeds. Their dull, streaked feathers provide perfect camouflage against native shrub leaves, while their long, breathy, trilling songs are a signature sound of spring on the range. Because they depend so heavily on large, unfragmented landscapes, healthy populations of Brewer’s sparrows are a key indicator of a thriving, well-managed rangeland ecosystem.
Where short prairie grasses like blue grama and buffalo grass break up the sagebrush valley, you’ll find the thick-billed longspur (Rhynchophanes mccowni). This species relies heavily on grazing to keep vegetation low; without livestock or bison disturbing the grass, their nesting habitat disappears.
On their breeding grounds, they feed heavily on protein-rich grasshoppers. During springtime, males perform incredible aerial courtship displays: They fly up to 30 feet in the air and "parachute" back down on outstretched wings with their white tail feathers spread wide, singing a warbling song to impress females and mark their territory.
Pronghorn (Antilocapra americana) are gorgeous, iconic fixtures of Southwestern Montana's open valleys. While commonly referred to as "pronghorn antelope," they aren't true antelopes at all; their closest living relatives are actually the African giraffes and okapis.
Built purely for acceleration and endurance, pronghorn are the fastest land mammals in the Western Hemisphere, topping out at speeds over 55mph, with this extreme speed attributed to a prehistoric evolutionary "arms race" with the now-extinct American cheetah (Miracinonyx). While modern wolves and coyotes can't come close to matching a pronghorn's pace today, these remarkable animals retain their incredible speed and massive heart-and-lung capacity, allowing them to cruise effortlessly across open rangelands.
Small, long-legged, and undeniably cute, the burrowing owl (Athene cunicularia) is one of the range's most charismatic residents. Unlike most owls, these birds are diurnal, meaning they are active during the day and can often be spotted standing guard on fence posts or mounds.
Burrowing owls have a fascinating relationship with prairie dogs and other underground mammals; because the owls can't dig their own homes, they rely entirely on abandoned burrows for nesting and shelter. These opportunistic hunters eat a wide-ranging diet that includes insects, small mammals, lizards, snakes, and birds. Highly sensitive to habitat loss, their presence is a great sign of an intact, biodiverse grassland.
Ranching landscapes are complex, working environments. During the visit, the team noted that this ecosystem is facing real-world challenges, including severe ongoing regional drought and water access issues. This is where our work regenerating the landscape becomes crucial; by combining rotational grazing strategies with targeted infrastructure improvements, we can significantly boost soil health, turning vulnerable land into a thriving, resilient ecosystem.
According to the Natural Resources Conservation Service (NRCS), every 1% increase in soil organic matter lets an acre of land hold roughly 20,000 gallons of extra water. That moisture doesn't just keep pastures green longer during a dry spell, it also helps safeguard the land against wildfires. As research from the USDA and fire ecology experts shows, soils rich in organic matter maintain higher plant moisture levels and soil humidity, creating a natural firebreak that slows down fire spread and helps landscapes bounce back faster if a burn does occur.
Hand-in-hand with our landscape restoration work, the ranch is actively participating in a broader ecological monitoring network, with ongoing research from local university programs and regional partnerships. Cultivo is actively working to coordinate with these existing initiatives, synthesizing data and supporting local land stewards.
By pairing high-tech monitoring tools, on-the-ground data collection, and deep, generational knowledge of local ranchers, we can build restoration strategies that support both wildlife and agricultural livelihoods.
Implementing our Biodiversity and Ecosystem Services framework in Montana reminds us exactly why we do this work: to accelerate investment into nature and regenerate the world’s land into healthy, resilient ecosystems.
As we refine our field protocols and analyze the baseline data gathered in Montana, we move one step closer to scaling transparent, high-integrity nature restoration worldwide.
Stay tuned for more field updates as we continue monitoring biodiversity across our global project portfolio! Big thanks to Princeton Hydro's Mike McGraw, CSE, QAWB, ACE, Tanya Dapkey, CE, and Eric Zawatski, CWB, for providing photos and information for the species listed in this post!
New Jersey Governor Mikie Sherrill signed Bill S3403/A4007 into law, requiring sellers to disclose the presence of dams on properties being sold in New Jersey along with information regarding the dams' condition, inspection history, hazard classification, and ownership obligations. The law is intended to improve transparency during real estate transactions and help buyers better understand the responsibilities that can accompany dam ownership before becoming contractually obligated to buy the property.
For many, a waterbody can be an attractive property asset that enhances aesthetics, recreation opportunities, and property value. However, what is not always apparent is that the waterbody may be maintained by a dam, and ownership of that dam comes with legal, financial, and regulatory responsibilities. Because dams are regulated infrastructure, depending on their size and hazard classification, owners may be responsible for routine inspections, maintenance, repairs, emergency planning, and ongoing compliance with state regulations. In some cases, property owners do not discover the full extent of those obligations until after a real estate transaction is complete, resulting in unexpected costs and liabilities.
"Dams are critical infrastructure, but they also have long-term responsibilities. Owners can face substantial costs associated with inspections, maintenance, rehabilitation, and regulatory compliance, and those obligations often transfer with the property purchase," explained Geoffrey M. Goll, PE, President of Princeton Hydro and NJ-licensed Professional Engineer. "This legislation helps ensure that prospective buyers understand the presence and condition of a dam so that they can evaluate those obligations upfront. Families and business owners can make informed investments while preventing unexpected liabilities, promoting public safety, and encouraging responsible stewardship of aging dam infrastructure across the state."
The passage of S3403/A4007 follows months of advocacy led by The Nature Conservancy in New Jersey, which first proposed the legislation and worked closely with lawmakers, stakeholders, and bipartisan supporters throughout the legislative process. Through testimony, coalition building, and sustained engagement, the organization helped elevate awareness of the challenges and costs associated with dam ownership and the importance of providing prospective property buyers with clear and timely information.
"No family should learn after purchasing a home that they have also assumed responsibility for a structure that could require extensive repairs or ongoing compliance costs," said Rebecca Hilbert, New Jersey Policy Associate at The Nature Conservancy. "By requiring transparency for buyers upfront, this legislation supports consumers, enhances public safety and helps ensure that dams affecting New Jersey's rivers and communities are responsibly managed."
Section 1 of the New Jersey Dam Disclosure Law states, "A seller of real property located in this State shall disclose, on the property condition disclosure statement, whether a dam is located within the boundaries of the property and any actual knowledge of the seller concerning the dam, as required pursuant to this section, to the purchaser before the purchaser becomes obligated under any contract for the purchase of the property." The law also adds specific dam-related questions to the property condition disclosure statement, including:
Additionally, the law directs prospective buyers to New Jersey Department of Environmental Protection (NJDEP) resources regarding dam ownership responsibilities, dam removal, and hazard classifications to gain a better understanding of the implications of dam ownership before becoming contractually obligated or completing the sale transaction.
The law serves a broader public safety purpose. Better informed ownership can encourage compliance with dam safety requirements, timely maintenance and repairs, and informed decision-making regarding rehabilitation, dam removal, and river restoration.
These responsibilities are not insignificant. Under New Jersey's Safe Dam Act and Dam Safety Standards (N.J.A.C. 7:20), regulated dams must be inspected by a qualified New Jersey-licensed Professional Engineer every two to four years, depending on the dam's hazard classification. Regulated dam owners are also required to maintain an Operation and Maintenance Manual, while Hazard Class I and II dams must have a NJDEP-approved Emergency Action Plan in place. A regulated dam is generally defined as an artificial dike, levee, or barrier that raises the waters of a stream more than five feet above the usual mean low water height. Many property owners may be unaware that these requirements apply to a structure on their property until they begin exploring its regulatory status or ownership obligations, or receive a compliance letter from NJDEP.
These requirements exist to protect people, property, and the environment from the consequences of dam failures. When dams are not properly maintained, the impacts can extend far beyond the property boundary, potentially resulting in downstream flooding, property damage, environmental degradation, impacts to wildlife habitat, and, in the most severe cases, loss of life. By increasing awareness of dam ownership responsibilities before a property changes hands, the new law can help support safer, more proactive management of New Jersey's aging dam infrastructure while reducing the likelihood of unexpected costs and obligations for future owners.
In a press release from The Nature Conservancy the organization stated, "The Nature Conservancy supported the legislation because dams can have lasting impacts on public safety, local communities and the health of New Jersey's waterways. Ensuring property owners understand their responsibilities is an important step toward informed stewardship of dams that affect both people and nature."
We applaud The Nature Conservancy for spearheading this effort and building the bipartisan support needed to move the legislation from concept to law. We also thank Governor Sherrill, Senator John Burzichelli, Assemblyman Dave Bailey, Assemblyman Sterley S. Stanley, and the many legislators who recognized the importance of greater transparency for New Jersey homebuyers and businesses.

Work is underway at Strawbridge Lake as Princeton Hydro and Moorestown Township continue a lake restoration project focused on managing excessive spatterdock growth throughout portions of the lake. The effort is part of a broader, long-term strategy to improve lake health, enhance recreational opportunities, and support the ecological function of this important community resource.
Take a look at some recent photos from the field featuring Field Services Project Manager Matt Kreines operating the Truxor during spatterdock removal activities:
Spatterdock (Nuphar advena), also known as yellow pond lily or cow lily, is a native aquatic plant commonly found in lakes, ponds, and slow-moving waters throughout the eastern United States. While native aquatic vegetation plays an important role in healthy lake ecosystems, excessive growth can reduce open water areas, limit recreation, and alter habitat conditions. At Strawbridge Lake, years of monitoring and management have identified areas where spatterdock has expanded significantly and requires active management.
The current project focuses on removing overabundant spatterdock from targeted sections of the lake while preserving important habitat along the shoreline. In coordination with guidance from the NJDEP Division of Fish and Wildlife, a vegetated buffer is being maintained around portions of the lake's edge to provide refuge and spawning habitat for fish.
Using Princeton Hydro's amphibious Truxor harvesting machine, our team of licensed operators are cutting and removing dense stands of spatterdock from open-water areas throughout the lake. The harvested vegetation is collected and transported to the shoreline, where Moorestown Township Public Works crews remove the material for composting and final disposal.
These photos, captured by Matt Kreines from the operator's seat of the Truxor, provide a firsthand look at the spatterdock removal process in action:
The restoration work also encourages improved water circulation in the lake and increased dissolved oxygen, two important factors in maintaining water quality. The harvesting process also removes nutrients stored within the plant biomass, providing additional benefits.
The spatterdock management project builds upon years of planning, monitoring, and restoration work at Strawbridge Lake. Since the development of the Strawbridge Lake Watershed Management and Restoration Plan, Moorestown Township has invested in a variety of initiatives, including water quality monitoring, aquatic vegetation management, Children's Pond restoration, stormwater improvements, fishery surveys, invasive species management, and public outreach programs.
On May 2, Moorestown Township hosted a public information session at the Moorestown Public Library, where residents joined Township staff and Princeton Hydro Senior Manager and Certified Lake Manager Chris Mikolajczyk, CLM to learn about Strawbridge Lake management and watershed restoration efforts.
The presentation highlighted the history of restoration efforts at Strawbridge Lake, ongoing vegetation management activities, and opportunities for residents to help improve water quality at home through practices such as rain gardens, rain barrels, natural landscaping, and other stormwater management techniques. The session also provided community members with the opportunity to ask questions and learn more about the work taking place throughout the watershed.
As work continues, the Township and Princeton Hydro remain committed to advancing practical, science-based solutions that benefit both the lake and the surrounding community. Click here to learn more about our partnership with Moorestown Township to protect and restore Strawbridge Lake.
Each July, Lakes Appreciation Month invites us to reconnect with one of our most valuable natural resources: our lakes. Since 1998, the North American Lake Management Society (NALMS) has led this initiative to raise awareness about the ecological, recreational, and community benefits lakes provide, while encouraging people to take an active role in protecting them. This year, we’re encouraging you to take your appreciation further by learning, participating, and making meaningful connections with your local lake. Here are four impactful ways to celebrate:
No matter how well you know your local lake, there is always something new to discover. Visit at a different time of day, explore a new access point, or try an activity you've never done before, like birding, early morning paddling, or shoreline photography.
As you spend time on the water or along the shore, take note of the details. Look for changes in water clarity, plant growth, wildlife activity, and seasonal shifts. These small observations can deepen your appreciation and help you better understand how your lake functions. If something doesn't look right, like signs of a harmful algal bloom, the presence of invasive aquatic species, or other water quality concerns, take note and share what you see. Reporting observations to your local lake association or through tools like the bloomWatch app can support monitoring efforts and help protect your lake.
Take your lake visit one step further by joining the annual Secchi Dip-In. This long-running citizen science effort invites volunteers across North America to measure water clarity using a simple Secchi disk. The data collected helps scientists and lake managers track water quality trends over time. Participation is simple and meaningful, and every reading contributes to a larger understanding of lake health.
If you are new to using a Secchi disk, watch our step-by-step instructional video to learn how to take accurate measurements:
Lakes bring people together and create lasting memories. This month, take the opportunity to share your connection to your favorite lake and inspire others to get involved. Join the NALMS #LakesAppreciation Challenge by posting photos or videos that capture your experience. Capture a quiet sunrise, a family outing, or a day spent volunteering and show others what makes your lake special.
Looking for more ways to tell your lake story? Try one of these ideas:
When you share, be sure to include the lake name and the hashtag #LakesAppreciation to connect with the broader celebration.
You don't need to make a big commitment to make a meaningful difference. Small, consistent actions can have a lasting impact on lake health over time. Here are a few simple ways to give back:
Communities across the country are working together to protect and restore their lakes. Your efforts, no matter how small, play an important role in that collective impact.

When a dam is removed, what happens to all the sediment that has built up behind it?
That question was the focus of a recent Dam Busters webinar led by Geoffrey M. Goll, PE, President of Princeton Hydro and an internationally recognized expert in dam removal and river restoration.
During the session, Geoff shared insights on how sediment behaves during dam removal projects, how it accumulates behind dams, and how different materials such as sand, silt, and organic matter respond once the dam is removed. He also discussed the methods practitioners use to estimate how much sediment is likely to move, how quickly it will travel, and the risks it may pose downstream, along with the practical decisions project teams face, including when to rely on natural processes, when intervention is needed, and how to design a strategy that balances ecological benefits, cost, and potential impacts.
During the webinar, Geoff highlighted a real-world example of a dam removal project that required careful sediment management: the Paulina Lake Dam removal on the Paulins Kill River in New Jersey. For this project, the team implemented a phased dam breach, gradually lowering water levels to control the release of sediment and allow the river to begin forming its new channel. A portion of the sediment, particularly the highly organic material near the dam, was actively removed to prevent downstream impacts, while the rest was allowed to mobilize naturally.

To support the development of the 2025 D&R Canal Master Plan update, Princeton Hydro partnered with Clarke Caton Hintz to create a comprehensive geospatial dataset that reflects current physical, environmental, and social conditions through the park and surrounding region. The previous Master Plan, last updated in 1989, predated many of the advancements in geospatial data that are now available to inform planning and decision-making.
Princeton Hydro curated a selection of datasets covering a wide range of topics, including land use and development, topography, hydrology and water resource protection, flood risk, threatened and endangered species, demographics, and environmental justice, creating a detailed and consistent data foundation for the master planning process. These datasets were integrated into an ESRI geodatabase and made accessible through an interactive, user-friendly dashboard. Users can refine their exploration by selecting specific geographies, including Delaware and Raritan Canal Commission review zones, counties, and municipalities. This flexibility allows planners and stakeholders to better understand spatial patterns and relationships across the region, supporting more informed, data-driven decision-making.
Across each of these projects, StoryMaps serve as a bridge between technical analysis and public understanding. By turning complex information into interactive experiences, StoryMaps help support informed decisions and build stronger connections to the environment.
Wissahickon Valley Park is one of Philadelphia’s most treasured natural resources, welcoming more than two million visitors each year. Over time, flooding, erosion, and stormwater runoff have taken an increasing toll on the park, threatening water quality, trail safety, and recreational access.
To help protect and sustain this vital landscape and community resource, Friends of the Wissahickon (FOW), in partnership with Princeton Hydro, is conducting a comprehensive resiliency and flood study along Forbidden Drive and its seven adjacent access trails. One of the most important voices in this process is yours. A public survey is now open through June 6 to gather input on flooding, erosion, and trail conditions in these targeted areas. Your feedback will play a key role in shaping the study’s priorities and recommendations.
The new Streambank Resiliency and Flood Study builds upon the 2017 Forbidden Drive Drainage System Assessment and expands its focus to address ongoing challenges such as stormwater runoff, sediment discharge, streambank instability, and interior flooding along Forbidden Drive and its adjacent trails. As part of the study, Princeton Hydro is reassessing previously identified drainage features and conducting a comprehensive site evaluation to better understand how conditions have changed over time and where new problem areas have emerged.
At the first public meeting earlier this month, community members played an active role in shaping the direction of the study. The session began with an overview of the project’s purpose, scope, and methodology, including preliminary findings on areas most vulnerable to flooding, sediment discharge, and streambank instability. Attendees also had the opportunity to ask questions and engage directly with the project team, helping to build a shared understanding of the challenges facing the park.
Following the presentation, participants took part in an interactive mapping exercise designed to gather site-specific knowledge from those who know the park best. Working in small groups around large, printed maps of the study area, attendees identified flood-prone zones, areas of active erosion, and locations where trail conditions have declined over time along Forbidden Drive and its access points. Participants marked up the maps and shared observations, stories, and ideas for potential restoration opportunities, creating a collaborative and hands-on dialogue about the park’s needs.
This exercise generated valuable, location-specific insight that is already informing the study. Participants highlighted:
In addition to identifying problem areas, attendees also shared perspectives on what makes the park special and where restoration efforts could have the greatest impact. This type of feedback is critical to ensuring the study reflects real-world conditions and community priorities. To ensure the most comprehensive understanding of conditions in the targeted areas, the project team is looking to hear from an even broader range of park users.
While engineers and scientists are conducting in-depth field investigations and comprehensive technical analyses, they do not experience the park in the same way as those who use it regularly. The firsthand perspective of park visitors is invaluable for identifying problem areas and guiding solutions and priorities that truly reflect how the park is used and experienced.

Conservation professionals, land stewards, and researchers from across New Jersey gathered for the New Jersey Invasive Species Strike Team Conference, the most comprehensive statewide forum dedicated to invasive species management. The conference was presented by Friends of Hopewell Valley Open Space (FoHVOS), an accredited nonprofit land trust committed to land protection, resource conservation, and community engagement.
The conference was held at the Boathouse at Mercer Lake, which provided an ideal backdrop for a day focused on protecting New Jersey’s natural landscapes. The conference, which Princeton Hydro was proud to sponsor, included exhibitor tables, networking opportunities, and a variety of presentations. The day kicked off with welcome remarks from Jenn Rogers, Executive Director of FoHVOS, and representatives from Mercer County Parks. Educational sessions throughout the day explored the dynamic and evolving challenges facing New Jersey’s ecosystems, cutting-edge academic research, and practical, field-based solutions for mitigating invasive species:
Native to the Yangtze and Amur River basins in China, the silty pond mussel (Sinanodonta woodiana) is a highly invasive freshwater species that has spread worldwide, often without detection. Its life cycle makes early identification especially difficult: microscopic larvae, known as glochidia, attach to the gills of host fish, allowing the mussel to move unnoticed through connected waterways and establish new populations far from their point of origin.
This stealthy mode of transport is believed to be how the silty pond mussel arrived in the United States. The species was first documented in 2010, when it was discovered in New Jersey Conservation Foundation’s Wickecheoke Creek Preserve, which previously operated as a fish farm and is now protected land. Although the mussel had likely been present for several years, its absence from North American records meant it went undetected until genetic confirmation was completed. Investigations identified invasive bighead carp imported for aquaculture as the most likely pathway of introduction.
The discovery raised immediate concern because of the preserve’s ecological significance. Located in Hunterdon County, the Preserve supports nearly 400 native plant species and 14 miles of high‑quality streams. It sits at the headwaters of Wickecheoke Creek, a tributary of the Delaware River that connects to the Delaware and Raritan Canal, part of a drinking water system serving approximately one million New Jersey residents.
Once established, silty pond mussels can overwhelm aquatic ecosystems. During the presentation, Scott Churm and Dr. Emile DeVito explained that invasive mussels may account for over 75% of total benthic biomass in affected waterbodies. Such dominance can disrupt food webs by outcompeting native mussels; harm fish when larvae attach to their gills, sometimes triggering fatal biological responses; reduce biodiversity; and alter water chemistry, ultimately degrading habitat quality for both plants and animals.
Following the initial discovery of the silty pond mussel, testing conducted by the New Jersey Invasive Species Strike Team, the New Jersey Endangered and Nongame Species Program, and the North Carolina State Museum of Natural Sciences confirmed the presence of this invasive species. With confirmation in hand, early eradication efforts began, centered on careful detection and sustained monitoring to better understand the scope of the infestation.
To assess the extent of the mussel’s presence, response teams combined traditional field surveys with advanced scientific techniques. This integrated approach included SCUBA and snorkel surveys, physical sampling of mussels and stream substrates, and environmental DNA (eDNA) testing, which detects trace genetic material released by organisms into the water and allows scientists to identify species that may not yet be visible during field inspections.
Together, these methods made it possible to find both established populations and early-stage infestations. In 2021, researchers applied highly sensitive genetic markers developed by Rutgers University to determine whether the silty pond mussel had escaped the former aquaculture ponds and spread into surrounding waterways. Initial eDNA sampling focused on Wickecheoke Creek Preserve, where testing provided a clearer picture of the species’ distribution and helped validate findings from visual surveys.
Monitoring efforts later expanded beyond the preserve. In 2021 and 2022, water samples collected from the Raritan River at the confluence of the Millstone and Raritan Rivers produced positive eDNA detections for silty pond mussel. These results pointed to the potential presence of a population within the Raritan River Watershed and highlighted the need for a rapid, coordinated response to prevent further spread.

These results indicated the possible presence of a population within the Raritan River watershed and reinforced the need for a rapid, coordinated response to limit further spread.
Eradication efforts at Wickecheoke Creek Preserve began with extensive planning and regulatory review to ensure treatments would be both effective and protective of surrounding ecosystems. Before field work could proceed, the project team secured all required state permits, verified pond depth and water volume to calculate precise treatment dosages, posted public notices and signage throughout the site, and established protocols for daily safety briefings and site inspections. This preparation ensured the project was conducted safely, transparently, and in full compliance with permit requirements.
Following this approval phase, Princeton Hydro’s licensed applicators, working closely with SePRO and project partners, implemented a targeted treatment using Natrix®, an EPA-registered chelated copper pesticide formulated specifically for invasive mollusk control. Treatments were designed to maintain copper concentrations at 1 part per million for a minimum of 96 hours. To ensure consistent and accurate dosing, water samples were collected and analyzed twice daily at an onsite laboratory throughout the treatment period.
This work is part of an adaptive, science-driven eradication strategy that depends on clear roles and close collaboration among partners. The approach is both preventative and responsive, allowing the team to adjust tactics based on monitoring results and site conditions. The project is supported by funding from the U.S. Fish and Wildlife Service and the Delaware River Greenway Partnership through the Lower Delaware Wild and Scenic Program.
Looking ahead, the work at Wickecheoke Creek Preserve reflects the themes emphasized by Scott and Emile during their presentation: the importance of early detection, scientific innovation, and coordinated response in addressing invasive species. Continued collaboration among scientists, agencies, conservation organizations, and local communities strengthens the ability to respond quickly and adaptively, while education and public awareness support long-term prevention. Together, these efforts contribute to the protection of native species and freshwater systems and support the ongoing stewardship of our natural spaces.
