Rushton Nature Keepers: Inspiring tomorrow’s conservationists

May 31, 2022 By Blake Goll

In the midst of today’s chaotic pace and uncertainty, children need more than ever those timeless moments in nature that are so crucial to their creative rejuvenation, problem-solving skills, and emotional development.  Rushton Nature Keepers (RNK) is a membership program seeking to do just that and more. The purpose is to provide area children, ages 8-11, with opportunities for meaningful connections to nature that they can take with them for the rest of their lives.  In so doing, we hope to help build an army of earth conscious adults who will value the land and understand the importance of conservation. 

Established in 2018, RNK is the Willistown Conservation Trust’s multi-disciplinary approach to children’s environmental education. Through a range of transformational experiences offered throughout the summer and fall at Rushton Woods Preserve and other Trust preserves, Nature Keepers develop a close relationship to nature and a comprehensive understanding of conservation.  The unique thematic approach of RNK follows the Trust’s conservation disciplines: birds and wildlife, regenerative farming, watersheds, and healthy habitat.  

From releasing wild birds at the banding station and discovering aquatic insects that live in the stream, to harvesting potatoes on the farm and exploring native wildflower meadows, Nature Keepers grow their sense of wonder while learning that they can seek refuge in nature—healthful traits that will persist through adulthood (see more in Plant a Love of Nature in Your Kids). In return for these rich benefits, the students develop a lifelong conservation ethic that fosters mindful stewardship of our planet.

Dedicated Nature Keepers who show satisfactory attendance across the varied programs earn their Rushton Jr. Naturalist title at the end of the year.  The Junior Naturalists attend a “graduation ceremony” during which they are tasked with defending Rushton from a barrage of various development scenarios, using the knowledge they have gained throughout the year.  Past Junior Naturalists valiantly spoke for the birds that use Rushton during migration, the wildflowers (and their associated insects) that promote pollination of the crops, and the forest that protects the watershed as they vehemently opposed (imaginary) plans for twenty townhomes, conventionally farmed soybean fields, and parking lots.

“You are the future keeper of our natural world.  It will be up to you to protect it, cherish it, and teach others about it. In our rapidly growing human population, Nature will need all the help she can get,” said Education Programs Manager Blake Goll to the Junior Naturalists.

It’s all about restoring our relationship with nature. One of the pillar objectives of RNK is to learn about the many intricate connections within nature and how humans can play a positive role in conserving its integrity. This type of education is just as paramount for children today as any traditional school subject. For in the end, Earth is the ultimate classroom and Mother Nature the eternal teacher.

What past RNK members are saying:

“There are a lot of people who really care about conservation and the approach you have taken at Rushton Nature Keepers has really been powerful to our family….not to mention the beautiful land and resources you share with us each time we gather”.  ~ Patty Neeb (parent of two Rushton Jr. Naturalists)

“Rushton Nature Keepers is such a gift for the people who can be open to it.  You gave us a chance to be on a farm, which is something I think we all have a deep yearning for.  There’s empowerment that comes from understanding farming.  It’s a self-sustaining environment. Being able to produce your own food…there’s power in that.”  ~Patty Neeb

“All my children have enjoyed your programs and I appreciate the chance to get them involved in nature and conservation. While my daughter is only 10 years old, I believe the activities at Rushton will encourage her to follow her passion for nature, birds and science throughout her life.” ~ Steve Oblack (parent of three Rushton Nature Keepers and one Rushton Jr. Naturalist)

“I can’t begin to express the deep appreciation we have for RNK. The tremendous passion, expertise, time, and care you put into the program is extraordinary. Absolutely extraordinary! Thank you for the important educational work you do and for the countless gifts you’ve imparted to our family.  What a privilege it’s been for our young people to experience! Thank you for making the world a better and more beautiful place for all.” ~Lizzie Rumbaugh (parent of three Rushton Jr. Naturalists)

Step Back in Time with Owen McGoldrick

May 24, 2022 By Monica McQuail

All photos are currently on display and for sale in the Rushton Conservation Center, May 17 – August 28.

INTRODUCTION BY OWEN MCGOLDRICK

The color photographs were made using a 4×5” Linhof view camera. Notch and clip marks are shown to emphasize a bygone era, which involved carrying a heavy view camera and tripod, loaded with Kodak or Fuji film, and taking a picture somewhere on the grounds of what is now part of the Kirkwood Preserve, or in the very accommodating and voluminous interior of our mid-19th century farmhouse and barn.

Dr. S.H. overlooks Grubbs Mill and Goshen Roads

“Silo Cap” was one of the very first photos shot with a 35mm Pentax for a beginning photography class at the Columbus College of Art, Ohio. Our family lived in the lower house of Massey Farm (always referred to as White Horse Farm by our clan) from 1963 to 1990. The photographs in this exhibit depict the house, barn and fields that surrounded the fence line.

The landowner, Dr. Robert Strausz-Hupé, lived in the mansion at the top of the hill. He was an Austrian immigrant with Old World ways, a plume of cigarette smoke and cravat. He served as a statesman, professor at Penn and a term as the US ambassador to NATO, as well as Turkey, Sweden and Sri Lanka.  Dr. S. H. could be stern, especially when it came to our lawn mowing abilities, or lack thereof; however, he was also generous, allowing us to use his glamorous swimming pool every summer day from 5 to 6 pm. What a relief it was to jump into that cool water on a hot, muggy summer afternoon. The pool was surrounded on three sides by apple trees which offered useful content for two of the pictures in this exhibit, not to mention homemade applesauce.

Here’s a tidbit. Mrs. Strausz-Hupé once called my mother and asked frantically if we had a car to pick up Dr. S. H. and a military general at the Philadelphia airport. Being the only resource available, off I went to pick up the good doctor and General Alexander Haig in the family VW. As a longhaired 16 year old with limited driving experience, it was a bit soon to be chauffeuring major political figures of national importance. After I dropped them off, mom asked me what they talked about. I replied, “Mostly themselves.”

Tidbit #2. Dr. Strausz-Hupé had an aesthetic streak. He was the first person to turn me on to the 18th century British artist and poet, William Blake. There we sat in his study with little hippie me looking at color plates of this visionary artist. Blake is still one of my favorite historical figures, and not only visually, but the whole daring philosophy of his creative universe is something to behold.

Growing up on a farm with a big barn to play in, acres of fields and woods to explore, and Crum Creek to swim and fish in, was more than a fair deal for any childhood. How remarkable it is that those fields and creek are today’s Kirkwood Preserve! Deep appreciation and a little awe goes to Bonnie Van Alen, Kate Etherington, Willistown Conservation Trust and the active group of local citizens for taking action and saving the day.

The select group of images were recently scanned and retouched in Lightroom and Photoshop and printed within the last two months on Epson Premium inkjet and Kodak professional paper. This is known as “straight photography,” where all effects happened on site and outside the camera, without machinations in Photoshop to create the visual results. The transparencies came out of a 40-year hibernation in carefully stored boxes through many a move, and now my old friends have returned.

GALLERY DESCRIPTIONS

All gallery photos are on display and for sale at the Rushton Conservation Center, May 17 – August 28.

1. The Barn is a Camera | A window shines a sunbeam inside the west storage room, or hay mow.

cam·er·a ob·scu·ra : a darkened box with a convex lens or aperture for projecting the image of an external object onto a screen inside. ORIGIN early 18th century: from Latin, ‘dark chamber.’

2.  Silo Cap | One of the earliest photos from the first year of photography at the Columbus College of Art and Design. I wished I’d thoroughly documented the silo since we have so few photos of it. It was demolished later that year in 1977, after being deemed an unsafe structure.

3. Inside Looking Up | Inside the silo looking up at the deteriorating rooftop. A worker would have stood on those steps and lifted the sileage from the outside on an “elevator,” which was actually no more than an iron bucket. Dangerous work.

4. Black and Light | The result of a photography assignment using Dektol as a developer for B&W film. Or was it M-D3? It gives a grainy, high contrast look to the print. I took two negatives and sandwiched them. The barn’s a camera, a playground, a studio, a subject, an object.

5. Northwest Side | I took this snapshot in the mid-1990’s. Those doors are usually called “X-braced” and lead into the upper threshing room. The double decker barn traces back to English antecedents. A recent shot of one of the storage rooms is shown below.

6. The Exemplar | I remember floating by that oak tree in a great flood in June, 1968. There was a continuous wave at the bottom of Barr road.
Crum Creek was flowing to the right of this tree at about a 5-foot depth, a moving lake 10 times its normal size. That’s when I went for a swim and my friend Tom thought I was drowning so he made Boy Scout signals on the edge of the field. You can still see the high water mark from that storm event, put there by the township on telephone poles.

 7. Pennsylvania Landscape | “Tootsie Roll” bales somewhere on Davis Road looking south. Archetypical Pennsylvania farmland nostalgia. For some reason, I think of the Civil War when I look at this print.

8. Cow Palette | Living amongst the Holsteins brought up mischievous thoughts of the black and white tonal scale in photography. But I didn’t expect the cow to be waiting for me on top of the hill. Hello Ansel Adams Zone System. That’s Crum Creek in the far ridgeline.

9. Speed of Light | From the third floor west bedroom looking into Wyeth country.

10.  A Single Excellent Night | The title comes from the name of an ancient Buddhist text. That’s a 35mm slide projected from a Kodak projector of a TV still shot (was it a Magritte documentary?) into the far room. I painted the walls yellow and asked a friend to pose with an umbrella. She put on my bowler hat. I wish I still had that bowler hat.

11. Flag Composition | Still life arrangement courtesy of the Strausz-Hupé apple grove. The antique dress was courtesy of mom’s shop in Berwyn. It was a lot of work to get those apples into our enclosed yard in cosmic order. The flag was a family heirloom from family ancestor and WWI flying ace, George Evans. One time I showed the photograph to the father of a very good friend who exclaimed, shocked and angry, “But that’s desecrating the flag!” (The flag should never touch the ground, let alone decaying apples.) You can’t predict some people’s reactions. But I got his point.

12. Thornley Bush III | I found this natural oddity and stuck it between barbed wire and a fence rail just outside of the mudroom. One time the field behind caught fire from an unmonitored rubbish burn and the fire department had to be called out to douse the flames. The next year the field grass grew back very, very green and healthy. Sometimes calamity brings an improvement.

13. Still Life with Moonrise | A Kodak projector beams a slide of the moon in the third floor bathroom. I was big into projecting slides into interiors and exteriors, and then photographing the on-the-site collage with a view camera. That’s called analog. Ya dig?

14. Three Tree Hill | A saddle sloped hill that was great for tobogganing. Brought to you by billions of years of tertiary history and a 4×5 view camera. Somewhere near those trees I remember there was a salt block for cows. After some research, sodium in the salt helps with the absorption of calcium and helps to avoid “grass tetany.” I tried licking that maroon colored block once as a kid and never did get grass tetany after that.

15. Priest at Crum Creek 

Crum Creek. I wonder what the Lenni-Lenapes called it?

This is a shot of Father Dinda launching a toy boat. He was a real fun character who used to come into my mother’s antique shop in Berwyn. Mom would always have some interesting items in the shop and that’s how I came to borrow the boat.  I love Father Dinda’s self-satisfied grin – a man of the cloth comfortable in his…cloth. How I got him on that rock I’ll never know.

We used to go swimming in one spot called the Sheep hole, where the creek was six feet deep. There was a rope swing on a pine tree, and swing we did into beautiful Crum Creek. I would get a stick and put a piece of bacon on a hook and fish from a large rock. In those summer days in the 60’s, I’d often see rainbow trout, which was always tantalizing because not once did I ever catch a trout with bacon. They don’t go for worms either. I’d inevitably catch a sunfish. This was Huck Finn style fishin’. One time I took my catch home and put him in our aquarium. We called him/ her, Sunny, he/she lasted all summer.

Right across from the big rock where I always sat, there was, and thankfully still is, a magnificent oak tree. Around the time I took Father Dinda’s picture, I set up the view camera in front of a tree in all its autumnal glory, The Exemplar.

17. White Horse Farm, 1900 | The house on the hill is the mansion where the Strausz-Hupé family lived.

From the Chester County Historical Society Archives.

18. The Lion in Winter | The home had a great fireplace. An excellent home for the holidays.

19. Beatle John | My brother John Pancoast posing in front of the apple cosmos in Alfie’s yard. It could have been a great album cover. John used to go to parties and tell everyone he was George Thorogood’s brother. It worked.

Connecting Students to Bird Conservation

November 17, 2021 By Blake Goll

Since I was introduced to Willistown Conservation Trust in 2015, it has been a privilege to spend many of my working hours in the field supporting the bird banding program at Rushton.  The time spent walking the net lanes and watching the seasons change over the last two years in particular has made it much easier to stay grounded during a time when it was often easy to find oneself feeling adrift. 

As an educator who primarily engages the public in natural settings, it was especially challenging to connect with our audiences, particularly K-12 teachers and students. However, if there’s one lesson to be learned from the challenges presented by the pandemic, it’s the importance of meeting and engaging with others where they’re at, which is an intrinsic part of good educators’ practice.

I had the fortune to connect with a group of such educators who dedicated time during the pandemic to exploring ways we could help them and their students connect with the natural world.  AIM Academy is a K-12 research-to-practice school in Conshohocken, PA that strives to support students who learn differently, often by using project-based learning strategies and emphasizing 21st century skills.  With students returning to the classroom, Alicia DeVane, Julia Bower, and Cherica Onyango – AIM Academy’s 8th grade science team – were eager to find ways to immerse students in social emotional learning through science education.

  • Ken Leister, County Coordinator for Bluebird Society of PA, and educator Caitlin Welsh at AIM Academy for the bird box building project.
  • The Mobile STEAM Lab truck at AIM Academy

We focused on introducing students to migration ecology with an emphasis on bird-human interactions to help students foster personal connections to local wildlife. Over the course of two weeks, students completed a learning module in which they were able to engage with educators both virtually and in the classroom through presentations, birding on AIM’s campus, and migration mapping activities from Birds Canada that use Motus wildlife tracking data. 

The experience culminated in a project that guided students to creatively promote human behaviors that can support bird conservation, like designing and installing decals to reduce window strikes around the school building, and recording PSAs about preventing interactions between birds and domestic cats.  Activities and other learning resources, as well as an overview of this and other experiences, can be explored in the Educational Opportunities section of the Northeast Motus Collaboration’s web page.

Seeing the ease with which students could activate their empathy through creative pursuits, we were then connected with Kathy Brandon who leads AIM’s Middle School STEAM program where students incorporate art and design principles into STEM disciplines. With the 2021 school year and field season in full swing, Blake Goll, the Trust’s Education Manager, and I took a break from the banding station to work with Kathy’s students and spread the message of bird conservation even farther than the AIM community.

After learning about the Trust’s bird banding program and our work to address the challenges faced by migratory birds due to habitat loss, students had the opportunity to build nest boxes for Eastern bluebirds with guidance from the Trust’s bluebird champion, Ken Leister.  

After building the nest boxes, Kathy plans to mobilize her program and connect with community partners at St. James School, a tuition-free school for underserved student populations in North Philadelphia. Following the AIM’s mission to seek equity and access for all to STEAM Education, Kathy will use AIM’s Mobile STEAM Lab to share cross-curricular learning experiences like the nest box project with St. James Schools’ students and community.  “I really appreciate our collaboration,” Kathy said. “Maybe one bird box at a time we can make a difference for our environment”.

Flooding 101

August 23, 2021 By Anna Willig

As we approach the last few weeks of summer heat and humidity, we approach peak seasons for thunderstorms and flooding. Last Thursday, heavy rainfalls led to the first major flood of the year in our area. At Ashbridge Preserve, Ridley Creek rose over 2 meters (7 feet) in about 3 hours, pouring out of its banks. In the wake of these floods, we wanted to take the opportunity to answer some commonly asked questions about the fundamentals of flooding.

What is a flood?

The United States Geological Survey (USGS) defines a flood as “any relatively high streamflow overtopping the natural or artificial banks in any reach of a stream” (USGS, 2019). In other words, a flood happens when a stream breaches its banks, resulting in water flowing over areas that are not normally part of the stream. Floods can occur for a number of reasons, from snow melt to rain to changes in tides. In our area, the most common cause of flooding is rain, often from summer storms, and snow melt after large snowfalls.

How frequently do floods occur? 

Floods can occur several times a year, whenever rain or snowmelt causes a stream to overflow its banks. Small floods, when the stream barely breaches its banks, are more common than large floods when the water pours out of its banks.

The size of a flood is determined by the peak flow of a stream or the greatest amount of water moving through the stream during a flood event. Peak flow can be determined by measuring the height of a stream; it is the highest height during the flood event. Higher peak flows indicate larger floods and lower peak flows indicate smaller floods.

This graph shows water depth over time and nine floods that happened at Ashbridge Preserve in the Summer of 2018. The blue line represents the depth at which the stream completely fills its bank–a flood occurs any time the water rises above this depth. Each spike represents a rainstorm and the peak flow, which determines the size of a flood, is the highest depth in each storm. The star represents the peak flow of the flood that is pictured above.   

Floods are classified by how often we expect them to occur. A 100-year flood is a flood of a given size that has a 1% chance of occurring each year. Similarly, a 500-year flood has a 0.2% chance of occurring each year and a 1000-year flood has a 0.1% chance of occurring each year. However, this does not mean that a 100-year flood will only occur once every 100 years or that a 1000-year flood will occur once every 1000 years. It simply refers to the likelihood of such a flood happening each year. 

How do you stay safe during a flood?

Floods in our area can be dangerous, even life-threatening. According to a recently completed Hazard Risk Assessment by Chester County, flooding is the second highest risk hazard in the county. Floods can damage property, destroy roads and bridges, and threaten human lives. 

Floodwaters are most dangerous for drivers, especially when drivers try to cross flooded roads. Twelve inches of flowing water will move a car, and 2 feet of water will easily sweep a car away. Even just a few inches of water can immobilize a car, stranding drivers in the middle of a road. If you are driving during a rainstorm, do not drive through any floodwater. Floodwater is often dark and murky, making it difficult to judge how much water is actually on the road and if the water is flowing. Turn around and find another route or pull over and wait until the water goes down.
