Community Clean-up Day

It’s time for spring cleaning! On March 16 we’re calling everyone who cares about nature to join us for a community cleanup day at the Schuylkill Center. We’ll be working along the roadside picking up trash, cleaning up fallen branches, and getting the Center ready for the spring season. Light snacks and refreshments will be provided. So roll up your sleeves and come out to make a difference for the neighborhood!

What to Bring: Gloves and bags will be provided for litter pick up, as well as tools for invasive species management. Have your own tools and supplies? Feel free to bring them! Dress for the weather and be sure to pack your water bottle.

Where: Meet us at the corner of Hagy’s Mill Road and Port Royal Ave at 10 a.m. Look for our Schuylkill Center white welcome tent where our staff will meet you to share tools and instructions for cleaning up. Volunteers can park in our Hagy’s Mill Road lot, or towards the Roxborough Reservoir Parking Area.

Note: Groups and walk-ins welcome, however registration is recommended for staying in the loop about any changes in plans due to weather.

Restoring our Forests: A Town Meeting

White-tailed deer are just one of many issues compromising the future of our forests.

Walk into the Center’s forest– or any forest in the region– and you’ll notice a habitat filled with invasive plants. The bright yellow flowers of lesser celandine, while beautiful, carpet the forest floor right now. Devil’s walking stick, every inch of it converted by thorns, are shooting up in massive clusters. Garlic mustard is in full flower, its leaves being munched on by the caterpillars of cabbage white butterflies, an invasive non-native butterfly– and often the first butterfly we see in the spring.

And that’s just the beginning, our forests overflowing with a veritable United Nations of Norway maple, English ivy, Japanese honeysuckle, and Oriental bittersweet, not to mention tree of heaven, cork tree, Norway spruce, knotweed, purple loosestrife, and on and on. Sadly, these invasives crowd out the native plants, contributing to the reduction in the biological diversity of the plants and animals of Pennsylvania forests.

In response, numerous environmental groups across the entire region, state, and country are working so hard to restore our forests, meadows and wetlands, engaging friends and volunteers in pulling out the invasives and replacing them with natives. Last week, we celebrated Earth Day by planting a number of native trees in an area we have christened the Earth Day Forest– and every year at Earth Day our stewardship efforts are focused here, planting native trees back in our landscape on this special day.

Worse, climate change and very hungry deer, not to mention new threats like lantern flies, conspire to undo all this hard, necessary work. The very trees we plant may get damaged by deer, and in a few decades the climate may warm so much that southeastern Pennsylvania might no longer be suitable for some of them. 

So what do we do? What’s the path forward– if any? Join some of the region’s top restoration specialists in a lively conversation about the critical issue of restoring native habitats. The last in a spring series of Thursday Night Live virtual conversations, the “Restoration Roundtable: A Town Meeting” is set for Thursday, April 28 at 7:00 p.m. The free event is held over Zoom; register and receive the link. 

The event’s guests include Gary Gimbert, Senior Director of Land Stewardship and Restoration Coordinator of Natural Lands, one of the region’s largest non-profit land trusts that manages thousands of acres of preserves across the area, Steve Goin, the Schuylkill Center’s Director of Land and Facilities and a certified arborist, Steve Jones, a board member with Wissahickon Restoration Volunteers, and Rebecca Kagle, managing principal with Larry Weaner Landscape Associates. Each of these people will share their restoration experiences– and most importantly, answer your questions about this important topic.

What’s the best native tree to plant in my yard? What do we do about deer over-browsing our forests? What will the impact of climate change be on our forests? How can more of us help? And the most interesting question perhaps of all: can any of us restore any forest to anything it might have ever looked like in its history? Our four guests will answer all of your questions about restoring native habitats while offering their organizations’ unique perspectives. 

For the Center, this question is central to our land stewardship work. For the last 20 years, we have been actively engaged in a wide variety of restoration projects across our 340-acre forest, like putting up a deer fence to exclude those hungry animals from a 20-acre Wildflower Loop, giving spring wildflowers there a chance to flourish. We’ve planted several thousand trees, shrubs, and wildflowers throughout our forest in this time, desperately hoping a large number of them stick. Trouble is, we never know how many have– and we have to monitor them continuously.

So we have backed away from using the word “restoration” in our projects, and instead describe our work appropriately as “stewardship.”

We are actively working– every day– to improve the land while acknowledging we’re not sure we can restore it to anything it ever looked like before.

After all, we’ll simply never rid our forest of every invasive plant that is not native to this corner of the planet.

At the same time, we’re also not willing to concede defeat, not willing to raise the white flag, not willing to pack our bags and go home. We are caretakers of a massive sweep of forest, and will doggedly strive to improve it while openly acknowledging it is an uphill slog. We’re rolling that boulder up a very large hill, fully aware it might crash down on us anytime. 

So we soldier on. And will wrestle with our work openly on Thursday evening at our Restoration Roundtable, and invite you to wrestle with us. See you there.

Toad Detour Training

Each spring, volunteers shepherd thousands of toads safely across Port Royal Avenue as they travel to and from their breeding grounds at the Upper Roxborough Reservoir Preserve. If you’d like to help with this year’s Toad Detour, join us for this orientation. Volunteers can help for an evening, bring a Girl or Boy Scout Troop, or become shift managers, to help manage the many volunteers who help these toads. You’ll learn all about toads, toad handling, and shift sign-ups. Volunteers are needed for evening shifts from March through June.

Contact our volunteer coordinator at volunteer@schuylkillcenter.org or call 215-853-6270 to get involved.

Winter Bird Census

With leaves falling and the forest turning into a blanket of white snow, it becomes a great time for bird watching. Birds need to be active and feeding in order to stay warm in blistering winter temperatures, and the contrast of their feathers against the white snow and bare trees makes them easier to observe along our trails. In our annual census, we’ll monitor the abundance of bird species that winter in our forests and fields. All of the information we collect will be shared with other citizen scientists, helping us to better understand how our local bird populations change over time. Warm drinks and snacks provided. Registration is appreciated.

In the event of heavy rain or snow, the census will be rescheduled for Saturday, January 25.

 

Naturalist’s Notebook: The Missing Sponge

By Andrew Kirkpatrick, Manager of Land Stewardship

If you take a walk along Smith Run, coming up Ravine Loop below Penn’s Native Acres, the hillsides where the beeches, oaks and maples grow show signs of distress.  The structural roots of the trees are visible at the soil line when they should be tucked away cozily wrapped in the warm blanket of leaf litter and organic rich soil.  Instead, because of exotic invasive earthworms, which can be observed by scraping away the thin layer of leaves on the ground, the roots are exposed and left to fend for themselves in all of the elements; freezing winter winds, driving rains, and blazing sun.  If you look up, the impact on the trees is apparent.  Bare branches and diminished canopy reveal their stresses.  The trees are dying.  

In healthy, undisturbed forest soil, we would discover a universe of fungus, microorganisms, bacteria, and insects thriving. All of these elements facilitate the healthy growth and development of plant roots. The vast root mat matrix of the organic horizon (the top layer of healthy soil) in the forest acts like a gigantic sponge that collects water when it rains and holds it in storage for trees to use in the drier months of the year.  

However, in highly disturbed areas like the Schuylkill Center, the organic horizon of the soil is absent. Soil horizon is a technical term for the classification of the cake-like layers of soil.  The organic horizon is missing here because hundreds of years of agricultural use have long since removed the original rich soil and left mostly thin, mineral soil at the top of the profile.  In fact, parts of our property were in farmland almost until the Center’s founding in 1965. The forest has not been able to redevelop the O horizon as it might have otherwise, largely due to the activity of invasive earthworms.

Invasive earthworm and castings

Invasive earthworm and castings

The invasive earthworms are much larger than our native ones, tunnel deeper into the earth and voraciously devour the leaf litter that would accumulate annually in the fall, break down over time to replenish the soil, and rebuild the O horizon.  So what is left is a loose accumulation of worm castings on a destabilized base that washes away into our streams every time it rains, carrying many nutrients with them.  And when the dry times of the year arrive, the trees have no reserve of nutrients to draw upon.  Instead our forest is stressed and vulnerable to attack from pests and diseases that it would otherwise be able to fend off.  

Planting Fox Glen_5-20-17 (10)20170516_115508We can address these problems by improving the soil and providing the roots of trees with a healthy environment to grow and develop.  In our Fox Glen restoration site, as we planted new trees we covered the ground around them with wood chips to help the roots retain moisture.  The wood chips will break down over time and add to the organic content of the soil.  

If we want our forest at the Schuylkill Center to survive climate change and the increasing stresses that come from an urban environment, we must help it to be as resilient as possible by replacing the missing sponge.

Of Soil and Seeds

By Melissa Nase, Manager of Land Stewardship

With ice on the ground and some remnants of snow lingering in the shadows, it is hard to believe the growing season at Schuylkill Center will begin in just a handful of weeks.  For gardeners like me, these cold days are the perfect opportunity to leisurely browse the glossy, colorful seed catalogs and dream about what to add to the garden this year, the bounty of the harvest, and warm summer days spent among blooms.  I hope to add some more shade-loving native plants to my back yard, and stave off the continual encroachment of my neighbor’s English ivy.  Rarely, does the thought of soil enter into our daydreams – although, as any gardener will tell you, it is one of the most important components to any healthy, productive garden.  Besides the minerals and nutrients that soil offers plants, it is teeming with the microscopic life of the food soil web.  Bacteria, fungi, nematodes, and arthropods, along with the ubiquitous earthworm, break down organic matter, making nutrients available to plants and participating in a food chain that includes birds and even larger mammals.  Besides protecting your crops from pests and diseases, these soil creatures create pockets of air in the soil, affecting soil structure and drainage.

So, how can you ensure the health of your soil?  One step to consider, especially if you plan to grow food crops, is to get your garden soil tested.  There are many resources for soil testing, including a low-cost option from the PSU Extension program.  Analyzing the soil for nutrient levels, pH, and contaminants is a good initial step to deciding what action to take to get the best results from your garden.  Often, fixing nutrient deficiencies is as easy as mixing some more organic matter like compost or decomposed manure into your garden soil.

If you start your plants from seeds, the potting mix you use is also an important decision.  Most potting soils contain just a few ingredients: organic matter, a fertilizer, peat moss to hold moisture, and a component to help drainage and create air pockets, such as perlite.

SeedlingsAt the Schuylkill Center, we’re always seeking sustainability, and that includes our nursery practices.  Since the establishment of the Native Plant Nursery in 2006, it has been the goal of land stewardship staff to reduce and eliminate potential negative impacts on the environment due to the nursery.  So at the outset, this framework provided guidance as to the types of materials used in the nursery like fertilizer, soils, and seeds, and led to the decision to seek out a peat-free soil.  Although peat is used in almost all potting soils, it should be considered a finite natural resource because it is harvested at an unsustainable, rapid pace, yet only grows millimeters per year.  As a result, it takes the peat bogs hundreds of years to return to their original state, if they are not wiped out completely.  Just like trees, peat bogs store significant amounts of carbon.  In fact, they are one of the largest storers of carbon and greenhouse gases on the plant, which is a further reason to preserve them.

Organic MechanicsAll of this led us to Organic Mechanics, a local soil company which does not use peat in any of their mixes.  Instead, they use compost and coconut coir, both recycled materials with the added benefits of greater moisture retention and increased nutrient content.

This year, in preparation for spring planting, you can buy organic, sustainable soil through the Schuylkill Center.  Our first annual Soil Sale is underway now – you can pre-order a range of peat-free soil products at a discounted price, and pick up them at the Center on February 21st – just in time to start your vegetables.  More about that here.

Restoring Cattail Pond


By Melissa Nase, Manager of Land Stewardship

Toad in Cattail PondCattail Pond sits in a serene, sunlit woodland opening at the edge of our forest, just a few quick steps outside our back door.  It is a special place, nestled into one of the few areas on the property that is free from undulating topography, naturally protected by a steep slope uphill from it and surrounding trees.  Taking all of this into consideration, it’s not surprising that there are also ruins of a barn near the pond, part of a former homestead and a reminder of the rich history of this land.
