With the Spotted Lanternfly it’s Always Squash Season

By

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

By

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!

Public Notice of Accreditation Renewal

Volunteers Plant 300 Trees To Improve Ridley Creek Watershed

By

As the sun rose over the meadow that was formerly Ashbridge Lake on October 4, the first of our three days of tree planting, I stood and surveyed the planting area that was soon to be home to 300 trees and shrubs and felt a sense of excitement (and some stress) for the event that was about to take place.  Months of effort and planning had gone into making sure the next three days were to go smoothly.  Now, as I stand at the edge of the meadow and gaze at all of the beautifully planted and caged trees I have only one feeling: gratitude.   I was recently taught my first Lenape word: Wanishi (“Wah-ni’-shee”), which is a profession of gratefulness. Used to start every meeting, it feels appropriate to start this post of appreciation for all of the effort that went into this project.

Thank you to each and every volunteer who came out over the course of the summer to help prepare the planting site –from weedwacking and digging holes,  to planting, caging and watering the trees.  A major thank you to Mother Nature, who was thoughtful enough to break the drought with a gentle rain the day before the planting was due to take place, which made life much easier for the group of hunters who had volunteered to assist yours truly in digging holes for the trees. 

Each planting day was cool, clear, and perfect for all of the labor that took place.  Over 60 incredible volunteers came out over the course of three planting days – families, individual volunteers, friends, coworkers – each day was filled with laugher as friends, old and new, bonded over planting new life into the meadow.  Our fabulous Watershed team was reunited, as past interns and Drexel co-op students returned with friends; enthusiastic freshmen in the Drexel University Biodiversity, Earth and Environmental Sciences (BEES) program came out with their fearless leader and professor Dr. Marie Kurz; a local scout family came to work hard; Tree Tenders from Goshen and elsewhere leant their expertise and guidance. Two teachers from Kennett Square school district came out – neither of which knew the other had signed up!  Rain began to fall as the final cages were being placed around the trees, saving us from hauling buckets of water to our new plants.

We could not have done this vital work without the hard work of every single volunteer. Your effort is helping to improve the habitat both on the stream banks and in the channel.  As the roots of each tree grow into the soil, they will stabilize the sediment and slow the rate of erosion.  Over the coming years, the canopy will spread and begin to shade the stream and keep the water cool.  The impact of each tree will improve the water quality in our watershed, and we are excited to monitor the changes that take place over the next several decades.  Already, I am starting to see an improvement to the ecological value of this meadow (before it was filled with invasive canary reed grass and mile-a-minute vine and inhabited by a stunning number of non-native Chinese praying mantis). In the areas that we have cleared since the spring, we are seeing native sedges begin to appear and an increase of butterflies using the area.  I have been observing the wildlife starting to use the space – birds now move in each morning, hopping from tree to tree and exploring the new habitat.  As the birds learn, so do the deer, but the cages that were placed around the trees by volunteers should help to keep them safe from the curious white tails.

The next time you’re talking a walk through Ashbridge Preserve, please take a moment to pause in the planting site.  I hope you feel the same way I do as you look at trees growing in the meadow. We’re already planning the next round of planting, so please watch for announcements if you want to join us!  Also, take a look at the time lapse video we shot over the tree days.

Of course, none of this would have been possible without the generous funding provided by the Pennsylvania Department of Conservation and Natural Resources and TreeVitalize. A special thank-you goes to REI.  As if the joy of planting trees was not enough, they donated amazing door prizes to raffle off to a lucky volunteer each day! 

Variety is the Essence of Life

By

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.
