With the Spotted Lanternfly it’s Always Squash Season

November 14, 2019 By Communications Team

At our most recent free lunch & learn at the Rushton Conservation Center, Meagan Hopkins-Doerr provided a wealth of useful information about the invasive and destructive Spotted Lanternfly (SLF). Meagan is Coordinator for the Master Gardeners of Chester County and Master Watershed Stewards of Chester & Delaware Counties, and she travels the area providing informative sessions like this one on a variety of topics.

Background

SLF is an invasive species that was discovered in Berks County back in 2014. With few natural predators, it has spread and threatens the Pennsylvania economy. It is critical to manage this pest now. SLF was also introduced in South Korea, which is similar in size to Pennsylvania.

So, here are some of the highlights of actions you can take now:

Destroy the Eggs

The SLF adults have now died from the cold, but have left behind their egg masses. Here’s a photo of what they look like.

Females will lay eggs on virtually any outdoor surface. In addition to trees you may find them on:

Fence posts
Grills
Sheds
Lawn furniture
Outdoor seating cushions
Exterior walls (siding, brick, stone)
Flower boxes
Bird feeders

Careful inspection of your property for the egg masses is an important step in controlling the spread of the SLF. Each egg mass can contain, on average, 37 eggs. Therefore it’s important to destroy any you see. When you see one, here’s what you do:

Scrape the egg mass into a jar or similar container
Soak the eggs in isopropyl (rubbing) alcohol
Dispose of the container

You can also smash the egg masses, or burn them if you have a fire pit.

Limit the Spread

Willistown Conservation Trust’s program area is within the quarantine zone. At all stages of growth, SLF are very efficient hitchhikers. There are some things you can do to limit the spread of the SLF:

Check your car (wheel wells, grille) and any trailers and remove all SLF before departing. This is important ESPECIALLY before driving out of the quarantine zone.
Don’t park under infested trees
Do not transport firewood
Inspect any material stored outdoors before transporting it elsewhere

Remove Tree of Heaven

If you use landscapers or arborists, ask if they have received an SLF permit from the PA Department of Agriculture. For more information about the permit visit: https://extension.psu.edu/does-your-business-need-a-spotted-lanternfly-permit

Though the SLF will feed on other plants, the Tree of Heaven is one of its preferred hosts. If you have Tree of Heaven, it is important to remove them. You MUST use an appropriate herbicide to treat the tree before cutting it down or it will multiply.

Get Ready for Hatching

Banding. When the SLF eggs hatch in the spring, the nymphs will begin to forage. By banding trees they prefer, you can help to capture them. Bands should be checked regularly and replaced as needed. Excluder cages should be used to keep other animals away from the bands. Read more about use of traps here: https://extension.psu.edu/using-traps-for-spotted-lanternfly-management

Insecticides. If you have an infestation, it may be necessary to use insecticides. There are a variety of systemic and contact insecticides with varying degrees of efficacy against the SLF. Always read and follow the label before applying any insecticide. Additional information can be found here: https://extension.psu.edu/spotted-lanternfly-management-and-pesticide-safety

See the Penn State Extension website for instructions on how to band trees and for selection and use of insecticides.

Report. Report. Report.

Researchers need data. By reporting sightings of SLF you will help researchers understand how the SLF are moving. To report SLF you can go online to extension.psu.edu/spotted-lanternfly or call 1-888-4BADFLY.

Learn More

You can download a variety of helpful information at the PSU Extension website. The Trust also has some print materials left over from the lunch & learn. You’re welcome to stop by our office and pick up some while supplies last. We also have a small supply of scraper cards, which also have helpful information on them including the number to call to report SLF.

Watch for more informative lunch & learns coming up.

12.7 More Acres Conserved Forever

November 11, 2019 By Communications Team

The map of permanently conserved land in the Willistown area just got a little greener, thanks to Lawrie Harris. Lawrie donated a Legacy Conservation Easement to the Trust on November 11, 2019, protecting her 12.7 acres on Twinbrook Road from development forever. Located on Twinbrook Road in Easttown Township, in what is known as the Leopard Tract, the gently sloping site is primarily wooded and features a small tributary to Crum Creek named Grubb Mill Run. Several acres of open meadow area surrounds Lawrie’s home and garage, the only structures on the property.

The easement will limit further subdivision of the property and will protect its natural features that serve as important wildlife habitat, support the surrounding ecosystem and contribute to scenic views along Twinbrook Road. The easement defines most of the property as Sensitive Riparian Area, which include wetlands, hydric soils and floodplain, and limits the amount of disturbance allowed in these areas.

Lawrie shares her late husband Jay’s passion for the environment, and wants to conserve the land to ensure it will stay just as it is today, so both people and wildlife can enjoy it forever. Her decision to donate the easement was prompted, in part, by neighbors Kate and Ben Etherington’s recent decision to do the same. We are grateful to Lawrie for her foresight and generosity.

“I want to be absolutely certain that future owners will keep this property intact and take care of the stream and woodland. We don’t have many places like this left and we need to preserve them,” said Lawrie. “And the process of working with the Trust has been easy and enjoyable. Willistown Conservation Trust has a 40-year legacy of protecting land in our area.”

When you look at a the Trust’s protected lands map, you see a mosaic of open space comprising preserved parcels of all sizes – from hundreds of acres to just a few. And in an era when conserving habitat, protecting the quality of our water supply, and offsetting the impact of human activity is so vital, every acre counts.

We developed Legacy Easements, like the one that protects Lawrie’s land, specifically so owners of smaller parcels of land could protect their land in perpetuity. Legacy Easements are generally less complicated than traditional ones and can be tailored to protect features of an owner’s property that are personally and/or environmentally significant.

Thank you Lawrie, another hero of our countryside!

Variety is the Essence of Life

October 7, 2019 By Stewardship Team

The old saying goes that variety is the spice of life. In nature, variety is the very essence of life.

Hopefully you’ve read and enjoyed our recent blog posts about the importance of riparian buffers and tips for planting trees and shrubs, if you haven’t yet please take a look. You’ll find helpful guidance, which will be handy for World Planting Day coming up on October 22!

An important aspect of healthy riparian buffer is planting a variety of species, which will help support a variety of insects, animals, bacteria, fungi and other living things. A variety also looks nice, providing different colors and textures in your landscape.

To help you, we’ve assembled a collection of our favorite native trees and shrubs that grow well in riparian buffers.

You can also download a PDF here for future reference.

For detailed information about each of these, you can consult wildflower.org. You can also talk with a reputable native plant nursery or landscape designer about what variety of plants to select for your particular area.

Shocking Report Illustrates the Importance of Land Protection

September 20, 2019 By Bonnie Van Alen

Yesterday an alarming study in the journal Science was released, which detailed the dramatic and shocking decline of birds in North America. Three billion birds have been lost in the last 50 years. This staggering drop includes not only threatened species, but also common ones like Eastern Meadowlark, Wood Thrush, Barn Swallow, Blue Jay and even Baltimore Oriole (like the one pictured here, banded this year at Rushton Woods Preserve).

For every 10 Baltimore Orioles in 1970,
4 have been lost since.

Meadowlarks rely on healthy grasslands for habitat, which have been disappearing as human development and agriculture spreads across the land. Making matters worse without those grasslands, which are also needed to filter stormwater runoff, waterways that birds also rely on are being contaminated.

For 40 years, Willistown Conservation Trust has been permanently protecting land to advance conservation, including the preservation of vital habitat. Our Bird Conservation Program has been using this land to help study birds and promote their protection, operating a banding station, studying their health. Most recently, the Bird Conservation Program and their partners have been among the leaders in expanding the Motus Wildlife Tracking System throughout the Mid-Atlantic and the Northeast United States. The Willistown Area has even been designated an Important Bird Area by the National Audubon Society because of its habitat and biodiversity.

We will continue our fight to protect land and habitat that birds need to survive. And despite the frightening report, there are some things you can do to help. Here are a few simple actions you can take:

Keep cats indoors. It is estimated that domestic cats kill millions of birds every year.
Lobby your representatives in Washington, DC, to support the Migratory Bird Protection Act, the Clean Water Act, the Clean Air Act and other legislation that protects the environment.
Reduce (or better still eliminate) the use of pesticides (particularly neonicotinoids) and herbicides on your property.
Create habitat for birds in your own yard by maintaining shrub scrub, planting native plants, and providing water sources.
Participate in citizen science efforts to document bird populations.
Provide financial support to organizations that support bird conservation, like Willistown Conservation Trust.

While we are disheartened by the findings of this report, Willistown Conservation Trust is more motivated than ever before to continue our work to protect the land and the birds that rely on it.

We (and the birds) thank you for your continued support!

Riparian Buffer Planting – Step 3. Preserve

September 20, 2019 By Stewardship Team

The final blog post in our series of 3 is designed to help you plant native trees and shrubs in a riparian buffer (the land that borders streams and other waterways). While we have been focusing on planting in a riparian buffer, most of the tips provided will apply to planting trees or shrubs in other locations on your property.

Once your trees and shrubs are planted, it is important to protect them from deer damage! Placing tree guards or constructing your own fencing (photos below) around individual trees or shrubs is the best way to protect them from deer until they become large enough to survive without protection (typically 8-10 years).

Create your own fencing to protect your newly planted tree or shrub. Or…

Once installed, periodically check the plants and manually remove any aggressive vines climbing on the tree guards or fencing. Avoid the use of chemicals to fight the vines in riparian zones; they can harm the plants, insects and our waterways.

See our post about the importance of riparian buffers and our first post about preparing to plant and our second post about planting.

Learn how to give your trees and shrubs a strong start by attending one or more of our upcoming tree planting events on May 29, 30 & 31. More information and volunteer sign up for these upcoming plantings available soon!
