The Making of a Lifelong Nature Keeper

By

One of our primary goals in connecting youth to nature is to transform their mindset to viewing themselves as part of the natural world. Through repeated, memorable experiences in nature during their formative years, children learn to understand, respect, and love the earth. This critical foundation inspires lifelong choices to protect the environment, while also providing children with mental focus, emotional stability, physical health, and spiritual resilience. There is no better example than Catherine Oblack, a 16-year old student who has been involved with our youth education programs since she was 8 years old. The following is her story, told through her words.

One day that I will remember forever is the first day I got to go bird banding at Willistown Conservation Trust when I was eight. From the time I started elementary school, I loved nature and was especially obsessed with birds. I enjoyed watching and learning about birds and what is being done to protect them. I wanted to learn more and get involved, so this led to my family finding WCT and signing up for Junior Birders, which was their youth program that has now expanded into Rushton Nature Keepers.

When my dad told me that they had a bird banding session that I could attend I was ecstatic. I had learned about bird banding and how it is used to study and protect birds, but I didn’t know that I could go see it in person. I was also super excited that the target species were warblers, as I had read all about them but did not see them as much on my own. I spent the evening before reading over all the types of birds that they typically banded; I could not wait.

When I arrived in the early morning, I remember how excited I was as I walked through the beautiful trails to the banding station. The autumn woods were just starting to wake up and come to life as the sun rose above the tree line. When I reached the banding station, I was welcomed in along with the other guests. After I had been introduced to Blake and Lisa, they invited me up to watch a Common Yellowthroat warbler being banded. I had arrived hoping to see some birds, but it hadn’t prepared me for experiencing what it was like to be so close to a wild bird. I could see all the markings and traits that had been described in the guidebooks, and I was awestruck by the birds’ beauty.

After my first day at the banding station, I continued to go to bird banding before school whenever I could for many years, each season learning more not only about the birds, but also about the conservation efforts at WCT. I also participated in WCT’s other educational activities, like Rushton Nature Keepers, that helped me develop a deeper knowledge and appreciation of nature. This program helped grow my love for the natural spaces right around me and also respect for the people that work hard to keep them open. It also reinforced my desire to have a positive impact on our environment.

Going into my sophomore year in high school, I knew that I still wanted to be involved with WCT, so I helped Blake with Rushton Nature Keepers over the summer. Rushton Nature Keepers is a youth program that teaches kids (ages 8-11) about not only birds, but also about sustainable farming, our local watersheds, and many other aspects of conservation that allow curious kids like me to grow into young naturalists. It was a full circle moment when I got to help with the program and see other kids having the same experiences that fueled my own love of the natural world. I had so many wonderful and unique experiences in the junior programs at WCT, so it was amazing to help other kids get to experience these same things. Whenever I am at Willistown now, I still experience the same feelings that made me love learning about and experiencing nature firsthand and am inspired to help protect our natural lands and habitats.

Introducing WCT’s Strategic Plan

By

STRATEGIC PLAN | 2023-2025
Saving, Studying, and Sharing Land, Water, and Habitat


WHERE HAVE WE BEEN?

Land conservation efforts have been underway in the Willistown area for over 40 years. A satellite program of Brandywine Conservancy, formed in 1979, was known as the Willistown Area Conservation Program. With the encouragement of the community and key local conservation leaders, Willistown Conservation Trust (WCT) became an independent, community based land trust in 1996 with a committed and active Board of Trustees.

Using the Crum, Ridley, and Darby Creek watersheds as a boundary guide, WCT’s traditional program area encompasses 28,000 acres in Chester County and portions of Delaware County, and is located approximately 20 miles west of Philadelphia. Despite tremendous growth pressures that have converted many neighboring communities into vast tracts of sprawl development, the WCT program area still remains largely an oasis of green space.

Successful land conservation and stewardship paved the way for major growth within the organization. Since its founding, WCT has grown to include a suite of activities focused on science, stewardship, education, and community engagement. In addition to Land Conservation and Land Stewardship, these core activities include Bird Conservation, Community Farm, Watershed Protection, and Outreach and Education. This holistic approach to conservation explores the connections among land, birds, habitat, agriculture, and water, and educates the public on these connections.

Our land protection and stewardship efforts have been focused on the Willistown area; however, our work has a regional and national impact on conservation.

WHERE ARE WE GOING?

Over the next three years, as our land protection efforts thrive and new opportunities in our traditional program area diminish, we anticipate a growing emphasis on habitat conservation and restoration, education and community outreach. Within these conserved lands, we will use our growing body of research in bird, water, and agro-ecology to inform best practices and engage with the community to educate and inspire an ethos of conservation and care of our land, waters, and habitat where wildlife thrives. In addition, we will identify and consider land protection and conservation opportunities outside of our traditional program area that fulfill service gaps in surrounding communities and meet vital conservation needs, as we interact and collaborate with new communities and organizations.

We will continue to be a robust organization that is well established, broadly supported, and attracts leaders at the forefront of the conservation field. Our science-based programs will contribute research to inform conservation priorities and best practices on a regional, national and international scale. We will attract a diverse group of staff, Trustees, and volunteers who are deeply committed to the mission of WCT and bring a variety of perspectives, skills, and experiences to our work. We will offer robust community and educational programs that attract a wide swath of participants. We will use our established expertise and connections for the conservation benefit of communities outside our traditional area of focus.

Help Keep our Drinking Water Clean by Reducing Salt Pollution

By

Salt levels, often measured as chloride concentration, have increased dramatically in U.S. streams since the 1940s, when it became common practice in the U.S. to salt roads during winter storms. The Pennsylvania Department of Transportation applies over 800,000 tons of road salt per year to state roads in addition to a similar amount applied by municipalities and private citizens. These numbers add up to over 1.5 million tons of road salt applied per year in Pennsylvania alone, all of which eventually ends up in waterways. Though salt is naturally present in streams at trace concentrations due to the weathering of rocks and soils, the insects, fish, mussels, and amphibians that live in local waterways cannot tolerate the spikes in salt concentration that occur in winter.

Road salts threaten streams in two ways. During and after a winter storm, salt concentrations in streams can skyrocket as salty meltwater rushes in, creating conditions that are acutely toxic for fish and other stream creatures. Salts also build up in soils and in groundwater, slowly entering streams throughout the year and resulting in chronically elevated salt concentrations. Many stream organisms, particularly freshwater mussels, cannot tolerate these long-term increases in salt concentration and gradually disappear from streams.  

In the streams in the Willistown region, we have seen both acute spikes in salt concentration and evidence of chronic build-up through our monthly water quality monitoring program  in the headwaters of Ridley, Crum, and Darby Creeks. Chloride concentration, an indicator of salt pollution, is typically highest in winter months, with a notable spike occurring in February 2021. The spike in February 2021 was caused by snowmelt actively washing road salts into the streams. Chloride concentrations remain elevated throughout the year, often exceeding 50 mg/L, the maximum salt threshold that the most sensitive stream organisms can tolerate. 

Figure 1. Chloride concentration, an indicator of salt contamination, in the headwaters of Ridley, Crum, and Darby Creeks. All the red points indicate sample sites in Ridley Creek, the green points indicate sample sites in Crum Creek, and the blue points indicate a sample site in Darby Creek. 

Salt contamination in streams also harms human health and infrastructure. Road salt can end up in drinking water wells and water supplies and often is not removed by water treatments facilities. As salts move through the environment, they can pick up other pollutants along the way, further contaminating streams and drinking water. Salts also speed up the corrosion of metal pipes and concrete, shortening the lifespan of infrastructure. Similarly, overuse of salt rusts and corrodes cars, leading to expensive repairs. 

While road salt is necessary for safety, here are some ways to reduce salt pollution:

  • Shovel before applying salt. Even on cold days, the sun can still melt a thin layer of snow and may take care of the problem for you.
  • Do not use more than the recommended amount of salt. Only 1 mug full of salt, or 12 oz., is required to melt a 20-foot-long driveway. Read the instructions on your bag to see how much you need. 
  • If you feel crunching when you walk, you applied too much! Salt only works when it dissolves, so all the crystals that you feel crunching underfoot are not actually melting snow and ice. 
  • After the snow and ice have melted, sweep up any remaining salt! Save it and apply it during the next storm. 
  • Report large piles of salt on roads to your local municipality.
  • Share information about road salt and encourage your neighbors to use less!

Fish Shocking

By

On Saturday, October 22, the Watershed Protection Program joined scientists from the Academy of Natural Sciences of Drexel University’s Fisheries Team (ANS) to survey for fish in Ridley Creek at Ashbridge Preserve. It was a beautiful Saturday morning — crisp, bright, and perfect for learning more about the wildlife that calls Ridley Creek home! This event provided a unique opportunity to get a fish’s eye view of stream health, and it would not have been possible without the wonderful support of the talented Fisheries Team members Dr. David Keller and Paul Overbeck.

The morning started with a primer on fish survey protocols. Paul walked volunteers through the mechanics of electrofishing, a sampling technique where a small electric current is passed through the water to stun fish just long enough to be scooped up in a net and placed in a bucket. The scientists headed into Ridley Creek and began to survey, and immediately there was action in the water! 

As stunned fish began to fill the buckets, they were brought to shore and placed in aquariums to be studied. Within a short period of time, over 10 species of fish, crustaceans, and amphibians were documented. The Fisheries scientists quickly began to identify the wildlife and share what the presence of these creatures means for the ecosystem of Ridley Creek and surrounding landscape. Once the fish were observed in the aquariums, they were all safely released back into Ridley Creek. 

Included in the fishes that were identified was the American eel (Anguilla rostrata), a fish that migrates thousands of miles in its lifetime. This fish breeds in the Sargasso sea and migrates to headwater ecosystems — like at Ashbridge Preserve — where they can live over 25 years before completing their migration. The presence of this incredible fish showcases the connectivity of Ridley Creek with no large barriers to stop their movement to and from the Atlantic Ocean. American eel populations are declining due to large dams that block their migration, contribute to habitat loss, and overfishing of young eels.

Another fascinating fish present in the stream is the cutlip minnow (Exoglossum maxillingua). These fish are easy to identify up close, with a specially adapted three lobed, lower lip. These fish prefer gravel and rocky bottomed streams and are unable to thrive in polluted waterways where fine sediment buries rocky habitat. 

Black nose dace (Rhinichthys atratulus) are one of the most visibly common fishes in the headwaters of Ridley Creek and were abundant in the sample collected by ANS scientists! These fish are small, with big fish growing to be less than 4 inches long, but they school in shallow clear waters and can often be seen from the stepping stones at Ashbridge Preserve.

Fallfish (Semotilus corporalis) is the largest minnow native to eastern North America and they are abundant in the Ridley Creek headwaters! They are excellent targets for anglers, and their energetic behavior has earned them the nickname “freshwater tarpon.”

Rock Bass (Ambloplites rupestris) is well known to anglers as a sport fish, but this fish is actually an introduced species in Pennsylvania waterways! Since being introduced some time in the 1880s, they are actively stocked in waterways throughout the state.  

In addition to the fish that were sampled from Ridley Creek, ANS brought preserved specimens of fish of interest, including the northern snakehead (Channa argus), an aggressive invasive fish that has been spreading throughout the Delaware River watershed. 

This exciting and fascinating experience highlighted the importance of the ways that our activities on the landscape impacts the many lifeforms that call Ridley Creek home. The presence or absence of different species of fish can inform researchers of the health of Ridley Creek. There is a clear relationship with the development of the landscape and the decreasing health of freshwater ecosystems resulting in the loss of indicator species. As species disappear from the ecosystem, the entire system becomes weaker. As we head into a future that includes more frequent large storms, it is important that we focus on understanding how we can strengthen and improve the health of our systems to create resilience — the first step in this process is looking at who is present in the ecosystem.
