What the Study Explores Regenerative agriculture is often heralded as a win-win for soil health, productivity, and biodiversity, but how exactly do these practices affect bird communities? Birds are highly sensitive to agricultural change, and many North American species have experienced significant declines due to intensification of farming practices. The newly published study takes a closer, science-driven look at whether regenerative approaches can help reverse these trends. Drawing on extensive point counts, distance sampling, and acoustic recording units across agricultural landscapes, the research team examined nine common regenerative practices, including cover cropping, integrating livestock, eliminating tillage, and enhancing field margins. Rather than assuming a blanket benefit, the study asked a nuanced question: Which birds benefit from which practices, and why? The findings show that:

Our fear of bats, spiders, and snakes often stems from cultural myths, sensationalized media portrayals, and fear of the unknown. Misunderstanding these species highlights how a lack of education can shape our perceptions. With knowledge and curiosity, we can move beyond fear, find beauty in their unique roles, and appreciate the essential contributions they make to our world. For instance:
By addressing the roots of these fears, such as unfamiliar behaviors or misunderstood survival tactics, Princeton Hydro's webinar aims to replace myths with facts.
Bats, spiders, and snakes are ecological powerhouses! Snakes control rodent populations, reducing disease and property damage. Spiders eat disease-carrying insects, helping to maintain healthy ecosystems. Bats pollinate crops, disperse seeds, and consume agricultural pests, supporting food security and biodiversity.
The webinar also discusses practical ways to coexist with and support these animals, including:

Invasive species may be impacting your backyard without you even realizing it. These non-native plants, animals, and organisms can harm ecosystems, the economy, and even human health when they take root in areas where they don’t naturally belong.
If you missed our recent Facebook Live presentation on this important topic, don’t worry — the recording is now available for on-demand viewing! In the webinar, experts from the Princeton Hydro team - Michael McGraw, CSE, QAWB, ACE, Senior Project Manager and Senior Wildlife Biologist of Regulatory Compliance & Wildlife Surveys, and Jesse Smith, Aquatic Ecologist - provide practical tips on how to identify and manage invasive species, helping to keep your backyard and local environment thriving.
Invasive species are organisms that are not native to an area but thrive and spread aggressively, often causing harm to native ecosystems. They compete for resources, disrupt habitats, and can introduce diseases, leading to the decline of native species. Unlike exotic species, which may be non-native but do not necessarily cause harm, invasive species tend to simplify ecosystems by outcompeting native plants and animals.
A well-known example is the Emerald Ash Borer, a beetle responsible for the widespread death of ash trees across North America. Another, Phragmites australis, also known as Common Reed, is a highly invasive grass that dominates wetlands, lowering biodiversity and displacing native species. The spread of these and other invasive species can be exacerbated by human activity and even by climate change.
In their natural environment, invasive species have predators and environmental checks that keep their populations under control. However, when introduced to new habitats, they lack these natural controls, allowing them to spread rapidly. Invasive species can alter ecosystems by:
Freshwater ecosystems and wetlands are particularly vulnerable because it’s hard to contain the spread of invasives in these environments. Once established, invasive species are difficult to remove and can cause long-term damage.
The good news is that there are steps we can take to help prevent and manage invasive species in our communities. Here’s what you can do:
Educate and Share: Education is one of the most powerful tools in fighting invasives. Learn about which plants are native and beneficial to your specific region. Talk with your neighbors, community organizations, and local land managers about the importance of managing invasive species. And consider sharing educational resources like this blog and our on-demand webinar.
Reduce the Spread: Prevention is the best strategy. By planting native species, removing invasives, and avoiding the release of invasive species into the environment, you can help stop the spread.
Monitor Your Property: Routinely checking your property for invasive species is key to early detection. Reach out to local watershed organizations to get involved in monitoring efforts. Get involved with organizations focused on monitoring and protecting local lakes and waterways. In Virginia, the Smith Mountain Lake Association has launched “Dock Watch,” a community science program where volunteers collect water samples from select docks to monitor harmful algal blooms, track cyanobacteria levels, and report invasive aquatic species.
Document and Report: Learn to identify common invasive species in your area and report them to local authorities, such as your county extension office or an invasive species management team. In New Jersey, the Invasive Species Strike Team works to control the spread of these harmful organisms.
Here are some methods to consider when removing Invasive Species:

The New Jersey Department of Environmental Protection (NJDEP) launched its fourth annual Youth Inclusion Initiative. The program hopes to enrich young participants, who may not have the opportunity to explore open spaces in their community, with hands-on environmental field experience under the tutelage of NJDEP professionals and mentors.
This year’s participants consisted of youths from several different community-based organizations. These partners include Neighborhood Improvement Association (Trenton), Rutgers-Camden, The Work Group (Camden), Ranch Hope (Salem), Boys and Girls Club of Garfield, Groundwork Elizabeth, Ironbound Community Corporation (Newark), and United Community Corporation (Newark).
Over six weeks, eight community organizations guided participants as they engaged with professionals to explore careers in water and air monitoring, natural resource management, wildlife conservation, and other related fields. Additionally, a new component of the program introduces "community project days," where participants actively contribute to environmental projects within their neighborhoods. These projects enable participants to make a positive impact on their communities, fostering a sense of civic pride and environmental stewardship. Activities may include park cleanups, installing educational exhibits, and establishing community gardens.
The program has been expanded to include a full day of rehearsal, with a focus on public speaking abilities and mock interviews, regarded as integral components of professional development. Throughout the summer, participants will engage in resume and cover letter writing sessions and attend presentations led by guest speakers.
In addition to fostering personal and professional growth, participants devoted a substantial amount of their time to honing technical skills through hands-on activities. These activities included simulating environmental impact investigations, collecting macroinvertebrates from a stream to gauge water quality, interacting with fish at a state trout hatchery, and designing a park in collaboration with Green Acres staff. To further enrich their understanding, the program also incorporates a visit to the regional headquarters of the U.S. Environmental Protection Agency.
As part of this initiative for the third year in a row, the NJDEP's Division of Land Resource Protection Mitigation Unit invited Princeton Hydro and Mercer County Park Commission to host three sessions at John A. Roebling Park. Under the guidance of Princeton Hydro mentors Mark Gallagher, Dana Patterson Grear, and Mike McGraw, the team educated young participants about invasive species and the importance of restoring native landscapes. The initiative exposed attendees to the varied roles of environmental scientists, water resource engineers, geologists, restoration ecologists, wildlife biologist, pesticide applicators, regulatory compliance specialists, and communications professionals, thereby enhancing their understanding of these professions and sparking a fascination for the natural world.
The program began at Tulpehaking Nature Center like in previous years. After representatives from Mercer County Park Commission and Friends of the Abbott Marshlands introduced the site's history, Princeton Hydro discussed career opportunities in conservation and gave a brief overview of ongoing restoration efforts in the park to eliminate the invasive Common Reed (Phragmites australis), and NJDEP representative, Jessica Klein, gave a presentation about her work in wetland mitigation.
Before venturing into the Abbott Marshlands, the northernmost freshwater tidal wetlands along the Delaware River, the Princeton Hydro team conducted a health and safety briefing. They highlighted potential risks and exposures to ensure everyone's awareness. This briefing is a crucial part of prioritizing the safety of all participants in our work.
Shortly after setting out on the road to the site, the students received an additional lesson. Mark directed their attention to a nearby tree where poison ivy - a native plant - had stealthily climbed up the trunk. To their surprise, the young participants had mistaken the trailing vines for branches of the tree. This observation highlighted the remarkable ability of poison ivy to adapt to its surroundings, finding innovative ways to persist and thrive in its environment.
As the second group continued their journey down the path, they encountered a Fowler’s toad. Initially, its slippery texture startled them, but they quickly realized the frog's harmless nature. Through gentle pats on its head, they gained a newfound appreciation for these fascinating creatures, transforming their initial fear into a sense of wonder and respect.
Venturing through the marshland, the young explorers gained insights into wetland delineation. They witnessed the fascinating process of using a hand auger and a Munsell Soil Color Book to identify and understand the unique characteristics of wetland soils. In a delightful exploration of local flora, participants delved into the art of species identification using a specialized field guide. They learned to distinguish invasive plant species from their native counterparts, such as sensitive fern, which they were able to see during a short nature walk on a trail back to the nature center.
In a seemingly unremarkable area of the riverbank, the third group stumbled upon a startling discovery. Amidst the lush vegetation, a highly toxic plant known as poison hemlock flourished. The students were taken aback by its presence in an otherwise ordinary location. They had never encountered such a hazardous plant in their previous studies. The poison hemlock, with its delicate white flowers and feathery leaves, belied its deadly nature. The students were captivated by its beauty, but the instructors cautioned them against touching.
The encounter with poison hemlock and poison ivy served as a valuable lesson for the students. They realized that even in seemingly ordinary places, hidden dangers could lurk. They developed a newfound respect for the power of nature and the importance of exercising caution when exploring unfamiliar environments.
Ending the day, participants from the first group had the privilege of attending a lesson conducted by Wildlife Biologist Mike McGraw. With the assistance of the Nature Center's resident corn snake, Mike introduced the students to the fascinating world of reptiles. Overcoming their initial apprehension towards these slithery creatures, the students discovered that there was much more to snakes than they had previously imagined. Mike dispelled common misconceptions and fears, explaining that snakes are not inherently dangerous creatures but rather play a vital role in maintaining the balance of ecosystems.
The NJDEP Youth Inclusion Initiative began on July 8 and culminated on August 16 with a graduation and NJDEP Career Day where students had the opportunity to meet and discuss career options with various organizations who tabled at the event, including Princeton Hydro.

Could cows be a potential solution to climate change?
Livestock contributes significantly to climate change, with estimates ranging from 11.1% to almost 20% of global greenhouse gas emissions. This is primarily due to their methane-rich belches and flatulence. Given these substantial numbers, it may seem unlikely that cows could be part of the solution. However, Arizona State University Professor Peter Byck argues that cows themselves are not the problem but rather the manner in which they are managed and raised.
Progressive farmers can enhance soil health and increase carbon sequestration through a cattle grazing technique known as Adaptive Multi-Paddock (AMP) grazing. This practice, entailing the periodic movement of cattle between various land plots, facilitates the creation of carbon sinks by ranchers utilizing their herds. It mimics the historical grazing patterns of bison on the expansive U.S. plains, incorporating extended rest periods between grazing events to allow grass to flourish, thereby enriching the soil. Please note however, despite anecdotal evidence from scientists and farmers, comprehensive research to validate these assertions is lacking.
The extent to which traditional grazing farmers will adopt this innovative solution remains an open question. For several years, Peter Byck has dedicated himself to meeting with scientists and farmers. This journey has culminated in the creation of a four-part docuseries titled "Roots So Deep (You Can See the Devil Down There)." This docuseries chronicles Peter Byck's experiences and the knowledge he gained along the way.
The documentary features Princeton Hydro's Senior Wildlife Biologist, Michael McGraw, CSE, QAWB, and ACE. He is part of a multidisciplinary team of scientists whose research forms the basis of the documentary.
Michael's studies have focused on observing the dynamics of breeding bird populations in paddocks grazed by AMP and those continuously grazed. The documentary highlights that when managed effectively, farmland can boost productivity and profitability for farmers while simultaneously contributing positively to the environment and the diverse wildlife that shares the planet with humans.
During a screening of "Roots So Deep (You Can See the Devil Down There)," Michael discusses his deep emotional connection formed through a decade-long collaboration with scientists and farmers. This partnership aimed to explore new opportunities to enhance our soils, wildlife, and communities. He bestows upon the audience a powerful message: “It doesn’t matter if you believe in climate change because, at the end of the day, we’re supporting healthy American families and promoting biodiversity, which benefits us all.”
In this clip, Peter and Michael explore how individuals from diverse backgrounds and beliefs can find common ground in unexpected places. They discuss how environmental stewardship unites people, revealing shared values that transcend differences and inspire collective action towards a sustainable future.
The complete docuseries is now available for rent. Learn more and watch the series at rootssodeep.org. To learn more about Senior Wildlife Biologist, Michael McGraw, a CSE, QAWB, and ACE, click here.
With great enthusiasm, we introduce the newest member of the Princeton Hydro team: Michael McGraw, CSE, QAWB, ACE. He is a Senior Project Manager and Senior Wildlife Biologist in our Regulatory Compliance & Wildlife Surveys team who has with over 20 years’ experience designing and performing custom ecological assessments and wildlife surveys. We had the pleasure of sitting down with Mike for a Q&A session to delve into his new role, explore his aspirations for the future, and learn about what drives and inspires him.
A: What really motivates me is the amazing work culture and supportive team environment. I’m also excited about the types of projects that Princeton Hydro engages in which prioritize conservation ethics in their project selection process.
A: I am very proud to have contributed to the advancement and development of non-compliance-based wildlife studies over the past 15 years. This involves understanding the natural history of a particular site to guide ecological restoration and master planning. I hope to provide value-added services to ensure that decisions made on the landscape are beneficial to the wildlife. With this approach, we can ensure that the ecosystems we work on will benefit the wildlife.
A: In my professional work over the past decade, two aspects have brought me the most joy. First, working on extensive master plans, such as county-level park systems, large greenways, and vast conservancy lands, enables me to contribute my expertise in non-compliance-based ecological studies. These studies inform decisions that will shape the landscape for the next century.
Second, I find immense satisfaction in exploring the connection between humans and wildlife through research in working lands. My focus on adaptive multi-paddock grazing and farmlands aims to comprehend the significance of these practices in restoring soil health, water holding capacity, and water sequestration. This research holds the potential solution to saving grassland birds, which the U.S. is losing at an alarming rate. Being part of the research team that seeks to identify ways to save birds without compromising our food systems or the culture of family farming in America is truly a privilege.
A: I’ll never forget the first time I found a Northern Red Salamander; it was like a spark animal for me. It was at a pocket park in Delaware County, PA. We all got babysat by the neighborhood babysitter. 30 kids would come check in afterschool and disappear, and I would just go to the park to catch little stream-side salamanders. The first time I found a Northern Red Salamander blew my mind, and I’ve been seeking that joy and wonder of discovery ever since.
A: I’ve seen a lot of amazing things in the wild, but sometimes it’s as simple as witnessing the subtle communications between socially monogamous house finches. Just watching how they interact and feed their young is just astounding to me. It’s something that’s happening all around us, and we take it for granted.
A: I have three incredible daughters who are exceptionally talented naturalists. The challenge lies in picking the right excursions that match their intellectual interests and physical capabilities. Figuring it out presents a unique joy in navigating outdoor activities with my kids.
A: I absolutely love native plants. I have a 0.2 acre lot, where I immediately put 2,900 plugs that represent 75 native species. Honestly, it’s hard to say. Just like when people ask me what my favorite bird is, I tell them, “The one in front of me.”
Big thanks to Mike for generously sharing his insights and enthusiasm with us. His passion for wildlife biology and commitment to ecological restoration are truly inspiring. His expertise and dedication to conservation will undoubtedly make a significant impact here at Princeton Hydro! We eagerly anticipate the innovative strategies and valuable contributions he will bring to our projects.
