Collaborations for Restoration

How do we solve big problems like restoring a native tree that is functionally extinct? We work together.  Experts from diverse fields, organizations with shared values, and individuals with a passionate commitment to stewardship roll up their sleeves and make things happen. TACF member and volunteer Dan O’Keefe was witness and instigator of just this sort of collaboration this past July. He captured it in photographs and video for us to share here.

Chapter volunteers established a chestnut orchard at the Tyler Arboretum way back in 1997. It was the first such orchard planted in the state to serve as a germplasm preserve. Today, the orchard holds 136 of the 170 original plantings from seed taken from 20 different locations around the state.  In recent years, the volunteers at the Tyler have been seeking to replace trees that died with ones that have more certainty about their pedigree. Each year they manage controlled pollination of the Tyler trees with pollen from known sources like the Ort tree in York county. 

That brings us to the Delaware Nature Society (DNS). In 2019, a local hunter reported to Dave Pro, Land Steward at DNS that he had spotted a wild American chestnut (Castanea dentata) on the Coverdale Farm Preserve in Greenville, DE. Dave invited Bill McAvoy, the state botanist, and confirmed that the morphology fit with the native species.  Sara Fitzsimmons, Director of Restoration at TACF concurred but recommended going the extra mile.  Arrangements were made to send a sample from the Coverdale tree to Virginia Tech for genetic analysis. This is part of a larger effort to genotype 300 plus American chestnuts to answer two questions:

    1. Are they American and/or introgressed with something else?
    2. How diverse is American chestnut?

We will have to wait a year or more for the genotype confirmation. In the meantime, TACF accepts the morphological analysis that identifies the Coverdale tree as an American.

Back at the Tyler Arboretum, Dan O’keefe, aware of the Coverdale discovery spoke to Shelby French, the Propagation Manager raising the possibility and challenges of collecting pollen from the Coverdale tree, which stands at over 40′.  Shelby mentioned that Mt Cuba Center had a crew of arborists who might be willing to help. Conversations insued and a mutual agreement was reached. It was a good fit for Mt Cuba. Conservation of native plants is their core mission and the Coverdale tree is just a mile up the road. 

On July 6th, Bill Trescott, Arboriculture Manager at Mt. Cuba Center, and Mt Cuba Arborists, Scott and Eric Kelley (father and son dynamic arboriculture duo) traveled to the Coverdale Farm to collect catkins from the chestnut tree. I have to mention that Scott and Eric are both following in the footsteps of Scott’s father Clyde who was also an Arborist at Mt Cuba Center.

As you will see in the video below, Eric Kelley eagerly stepped up to perform the aerial work (he is the lightest and most agile of us all – perfect qualities for crawling out on small branches to gather catkins!).


Having the opportunity to simply stand in the presence of an American Chestnut in the forest was an experience none of us will forget. That we were able to aid in securing the species’ survival by using our aerial skills to collect catkins from the Coverdale tree made it even more meaningful. Conservation and collaboration – what a powerful combination!” __Mt. Cuba Arborist Team


2020 Chestnut Restoration Raffle Raises Funds and Awareness at PA Farm Show

Before COVID interrupted, the  PA NJ Chapter had started the year with a great week at the PA Farm Show in Harrisburg. This is a big annual event and we recruit over 20 volunteers each year to help manage our booth. By all accounts the big attraction at our booth this year were the cool prizes in our Chestnut Restoration Raffle. And top among these was an electric guitar, hand-crafted from American chestnut by Douglas Brownell, son of members Vicki and Dave Brownell. You can read the full story of how this came to be in page 6 our Fall 2019 issue of The Chestnut Tree, our print newsletter.

Winners were drawn in March at our Spring Growers Meeting turned Zoom webinar.  Despite the loss of our in-person gathering the raffle succeeded in raising over $700 and drawing  attention  to  the  American chestnut  with  the  amazing  hand-crafted  items  that  were donated  by  our  members.

Long Delayed Conclusion: On a hot saturday in July, Jean Najjar hand-delivered the Brownell guitar to the lucky winner at a pre-arranged meeting point near Raystown Lake. The young winner, Ayssa Payne, just 15 had purchased a single ticket at the PA Farm Show in January. She is a music lover and was really amazed that she had won. She shared this note of appreciation:

When I first saw the guitar, I was quite honestly in awe.  It was so beautiful and learning the history about the guitar just made it even better.  I entered the raffle pretty much expecting to not win, but knowing at least that I was helping out TACF in their mission to restore it.  The chestnut is such a beautiful tree and I have always loved nature and helping to preserve it in any way.  I just want to say thank you for this beautiful guitar and that I am hoping that will see these beautiful trees back into the wild again.

Let’s hope we hear some beautiful music in the future from this thoughtful young woman.

Roguing Time

As part of our breeding research at the PA/NJ Chapter research orchard at the Arboretum at Penn State, trees are inoculated with a blight to test their resistance. Trees inoculated with blight in 2019 are rated on a scale of 1 to 3 (1 being high resistance, 3 little to no resistance). Trees with a poor rating are culled to reduce competition for better-performing trees. Culled stems are burned on-site to satisfy APHIS permit requirements. So far this season 500 trees have been culled.

The Story of the Kelley Tree

by Sara Fitzsimmons, Director of Restoration TACF

In June, long-time member Tracey Coulter worked with her friend and colleague Ellen Roane to track down the status of the Kelley tree in Camp Hill, PA. Along with the Ort and Joliet trees, the Kelley tree was one of the first trees used in the Pa Chapters breeding program. Several of the progeny from this tree continue the lineage both in the PA/NJ Chapter breeding program, as well as in Maryland.

The owner of the tree, Mrs. Eleanor Kelley, had passed away in 2016 , and we lost contact with the tree and its new owner. Ellen took a walk to find out how the tree was doing, and met Janet Kelley, Eleanor’s daughter, who proudly cares for her mother’s American chestnut tree. Ellen will be collecting small leaves this month from the Kelley tree to include it in TACFs landscape genomics program.In 2003, Dave Armstrong pollinated the Kelley tree with pollen from a large surviving American chestnut in Virginia called the Amherst tree. Then, in 2004, he established the Kelley x Amherst (KxA) orchard in Codorus State Park. With both the Kelley tree and the Amherst tree having some moderate amount of blight-resistance, the resulting progeny have improved resistance, about that equal to half that of a Chinese chestnut.

For almost 10 years, Dave distributed seeds form the KxA orchard to many members of the Pa/NJ Chapter and beyond. Chapter member and volunteer Jay Brenneman will carry on the work Dave started at Codorus State Park, and we look forward to continued distributions from this location.

Making Connections

“I moved to Camp Hill in 1995 and while exploring the neighborhood, I saw a catkin-laden chestnut in a backyard.  Several years later, I talked about chestnut restoration for my “final presentation” on the way to becoming a Master Gardener. Apparently, Cumberland County Extension made note of that and when Mrs. Kelley called the office to invite them to visit her tree, the call was passed on to me. It was the very same tree that I had spied in 1995! You never know how these connections can be made!  Eleanor Kelly was a wonderful woman, with a grand sense of humor. On one occasion, when Dave Armstrong and I were pollinating the tree, George Weigel, gardening columnist with the Patriot News joined us. He then wrote an article about Eleanor’s tree and the effort to restore the American Chestnut.  Mrs. Kelley, standing straight with her trusty cane, supervised the operation.  She was an avid gardener, and when I stared intently at the purple loosestrife in her garden she said,” I know, but it’s so beautiful”. As was she”.

Update: Orchard at Penn State

May 9th brought an unusual day of snow squals and temperatures in the upper 20’s damaging tender buds and causing confusion in the plant world. While the chestnuts in the arboretum orchards suffered some freeze damage the trees have recovered as of late June. The more mature trees have male catkins present and the female flowers are visible. A few more weeks and chestnut pollen will be on the breeze.

In years past, this time of year is a flurry of activity, planting seedlings, mowing to try and stay ahead of the grass, inoculating trees, and closely watching flower development in preparation for pollination work. We are very busy this year as well. Over 700 young chestnut trees have been inoculated in the Arboretum orchards at Penn State and 2,400 more have been inoculated using the small stem assay (SSA) method in the shadehouse.

The oldest SSAs are 3 weeks old and the effects can be seen as some of the more susceptible seedlings have died from the inoculation. Over the summer up to 50% of the inoculated B3F2 seedlings should succumb to the inoculations. The remainder B3F2s will be planted in the arboretum in fall of 2020 and spring 2021.

More grafts have been made, and a lot has been learned on what works, what doesn’t, and where we can improve. Dr. Hill Craddock from University of Tennessee, Chattanooga gave a grafting tutorial to some TACF staff which should improve the success moving forward. In preparation for next grafting season hundreds of chestnut seedlings have been planted for use as root stock. The successful grafts will be kept in the shadehouse on campus this year before being planted in a portion of the chestnut orchards in the Arboretum @ Penn State.

Seeking Volunteers for Workday at Codorus State Park F2 Orchard

2016 Intern Marlin Graham helping with inoculations at PSU Chestnut Orchard

NEEDED: 6 – 10 volunteers to join us for inoculations at the Codorus State Park F2 orchard

WHEN: Friday, July 10th 

WHERE: Cordorus State Park in Southern York County, Pennsylvania

 Codorus State Park Orchards Map 2019  We will park at the parking area labeled in this map, then walk approximately 0.25 (1/4) miles uphill to the orchard location.

CONTACT: Sara Fitzsimmons: e-mail:

Description of Work:

You are welcome to join us for most or part of the day to assist with inoculations. You do not have to be available the entire time if you can’t do it. Even just a couple of hours will help.

We hope to have 2 teams of 4-5 people each. The individual tasks include:

    1. Optional: Data recorder and tree marker – outlining where the holes will be / are made
    2. Spraying a tree with 70% alcohol then punching 2 holes in the stem of the tree
    3. Putting a weak strain of blight fungus into the upper hole
    4. Putting a strong strain of blight fungus in to the lower hole
    5. QA/QC – Taping the inoculum-filled holes with masking tape and ensuring the process was completed appropriately.

Physical Requirements: Because we will be working within the bottom 3 feet of the trees, be aware that most of these jobs require squats, bending over, deep-knee bends, walking on knees, and/or skootching on bottoms. There are approximately 300 trees to inoculate, so if we can have 2 teams, each team will have about 150 trees to complete.

COVID Precautions: In light of the ongoing pandemic, and although we will be outside, we will work to ensure everyone is staying more than 6’ apart while also encouraging the use of masks. The trees are planted 3’ apart, so we will be sure everyone keeps 2 trees between them and the next person to ensure proper spatial distancing while working.

For more information on the inoculating process, here is a link to an artcle from the TACF Chestnut Journal, Summer 2015_Inoculation.

If you think you can help out, please let me know and I’ll put together a mailing list for everyone to keep on touch about the day’s activities.

Thank You!

Sara Fern Fitzsimmons, Director of Restoration – TACF®

Recently, we received an email with photos and a story about American chestnut snag at Cook Forest State Park. Many thanks to Jacqueline Goslin for sharing these images and her interest in the American chestnut.

The plaque reads: This snag or dead tree, has been standing since it was killed by the chestnut blight that moved through Pennsylvania, by the early 1920’s. The wood of this tree was very rot resistant and prized in the early lumber industry. It was used to build just about anything from tool handles to houses. The Civilian Conservation Corps CCC, salvaged some of these dead chestnut trees to build many of the park’s cabins, shelters, and the Log Cabin Inn Environmental Learning Classroom from 1933-1937.

Wildlife, such as turkey, bear, deer, and squirrels depended on this tree for food. It was a very fast-growing tree. Many trees that were felled in the logging era (1820-1920) averaged six feet in diameter. The largest chestnut tree ever recorded before felling was 54 feet in circumference, which makes it about 18 feet across.
