Gordon Natural Area
Upcoming/Recent Events & Ongoing Work
Invasive Species Early Detection and Response
As a suburban forest fragment with a significant amount of edge, the Gordon is extremely vulnerable to invasive species. Currently, 200 non-native plants are known to occur at the Gordon! Sixty-four of these are on the Department of Conservation and Natural Resources (DCNR) 'Invasive Plant List,' or fully half of the 132 species on the list.
Given the large number of non-native plants known for the Gordon, the ability of many of these species to quickly colonize areas, and the significant acreage that some of these species (e.g., Garlic Mustard, Japanese Stiltgrass, and Lesser Celandine) currently dominate, approaches for controlling these species are problematic. An increasingly favored strategy at the Gordon is to focus on the early detection and treatment of invasives. Through this approach, we can hopefully eliminate, or at least control, recently established species before they become too widespread and/or abundant at the site.
One recently observed non-native is Teasel (Dipsacum fullonum; Dipsacaceae). A native to Europe that was brought to the U.S. in the mid-1700's, this species is not listed as an invasive plant by Pennsylvania. However, it is well adapted to wet conditions along roadsides and it appears that the national interstate highway system has facilitated its spread during the last half-century. The seed heads of Teasel are quite distinctive (see second photo below) and can be easily observed along roadsides in the West Chester area.
Although many sources categorize Teasel as being a biennial, it is more properly categorized as a 'macrocarpic perennial,' i.e., a plant that grows in a rosette form until it has accumulated sufficient resources to flower and set seed, after which the plant dies. Under some conditions, flowering could occur by the second year (in which case, it would be functioning like a biennial), while under other conditions it can spend a longer time in rosette form.
The plant is also noteworthy for its perfoliate leaves: oppositely arrayed leaves that are fused around the stem, and which appear to have been 'pierced' by the stem (see third photo below). On larger stems, the lower pairs of leaves curve upwards forming a cup that can accumulate rainwater. We've observed numerous drowned invertebrates in these 'cups.'
Teasel was first observed in 2019 in the wet meadow at the eastern end of the GNA. A single clump of ca. five individuals just south of Stadium Road was noted at that time. This portion of the meadow borders the ramp for Route 202, and there are a number of non-native species in this area that have likely been introduced through the road. Initially, we had hoped to begin control efforts in 2020, however, due to time limitations, we decided to postpone that work until 2021. During 2020 surveys for Teasel, we found many individuals upslope from the original observation. During surveying in 2021, we found numerous additional occurrences, including many plants on the other (northern) side of Stadium Road.
During the first week of June, we initiated effort to remove Teasel from the meadow. GNA Student Interns Maeve Dowd and Noah Long removed 173 Teasel plants from the meadow. It should be noted that all our searches for this species have entailed only looking for the flowering (or, soon to be flowering) stems. There are likely many more plants that were in rosette form at the time of the surveys and which weren't detected. Nevertheless, as Teasel is said to average around 3,000 seeds per plant, Noah and Maeve's efforts have eliminated more than half a million Teasel seeds from the meadow. The actual number of potential seeds likely far exceeds this estimate, as a single flowering head is said to average 850 seeds and some plants are said to have upwards of 34,000 seeds. We plan to continue with these efforts next year and hopefully we'll be able to search for Teasel rosettes in the early spring and will be able to remove these plants at that time.

Welcome to the Robert B. Gordon Natural Area for Environmental Studies website.
The Gordon Natural Area (also referred to as 'the Gordon' and ‘the GNA’) occupies
approximately 126 acres (51 hectares) along the southeastern corner of West Chester
University’s campus and is administered in collaboration with the University’s Office of Sustainability. Established as a protected area in 1971, the GNA has since served as a refuge for
local wildlife and native plants, and as a multi-use setting for researchers, nature
lovers, runners, dog walkers, and people looking to reconnect with the natural world.
The Gordon Natural Area’s mission has two primary objectives:
- To preserve the land in an undeveloped state
- To serve as a natural ‘classroom’ for environmental studies
Objective 1. Preservation of the Land
Initially, it was thought that management could essentially be done in a ‘hands-off’ manner (other than any small-scale maintenance that might be required by Stadium Road and the trail system). However, over time it has become increasingly evident that the land requires a very active level of directed management. This is because the integrity of the GNA is threatened by a variety of forces: e.g., invasive plants, overgrazing (by deer), invasive insects and insect-borne pathogens, non-native earthworms, fragmentation, etc. In order to begin addressing these issues, the GNA Staff, along with numerous student volunteers, have undertaken fairly extensive reforestation and afforestation efforts in the GNA.
Objective 2. Be a Natural Classroom for Environmental Studies
Since before its designation as a protected area, the lands comprising the GNA were the site for a limited number of Natural Science classes, as well as being the location for field research by a few faculty members. After receiving protection, the GNA has received extensive use as an outdoor classroom, with more than 30 courses having utilized the land. In addition to use by numerous classes in the Department of Biology, courses from a broad range of other departments (e.g., Art & Design, Business, Earth & Space Science, English, and Social Work, among others) have also taken advantage of this amazing resource.
In 1971, the property was afforded protection. The protected land was named the Robert B. Gordon Natural Area for Environmental Studies in commemoration of Prof. Gordon, a science faculty member at West Chester University for 25 years. For the past 45+ years, WCU students and staff, as well as local residents (and their dogs), have continued to benefit from this decision.
A Rough Timeline of the Establishment of the Gordon Natural Area:
- 1969/1970 — Two students, Bradley Gottfried and Dave Fluri, work to convince the WCU Board of Trustees to establish a natural area.
- December 1971 — The WCU Board of Trustees decides to set aside some land to preserve the existing forest. This was WCU's contribution to the Earth Day movement.
- November 1973 — Dr. William R. Overlease, long-time Professor of Biology at WCU, formally dedicates the property.
The largest portion of the Gordon is situated between S. High Street and S. New Street (see image below). The land contains large blocks of mature forest, along with areas of secondary forest, seasonally-inundated floodplain, upland meadow, and maintained (i.e., mown) 'grassland.'
In the image below, the lands that are officially designated as the Gordon Natural Area are shown with pale green hatching. Additionally, the are in solid white in the lower right-hand corner of the image are 'unofficially' part of the GNA. However, despite it's not having been formerly dedicated as part of the GNA, this area is commonly used for research and teaching, and a number of trails in the GNA trail system pass through this area.
As was noted above, the GNA is a multi-use preserve, and we encourage WCU students and staff, as well as local residents, to come enjoy this great resource.
How To Get There
Located in West Goshen Township (Chester County, PA), about two miles south of downtown West Chester, the main entrance to the Gordon is at the southeastern corner of the R Lot, behind WCU’s Farrell Stadium (see map below).
On Foot or by Bike
The entrance to the GNA is about 1.2 miles from Sykes Student Union, a leisurely 20-minute walk or a 7-minute bike ride away. Use your own bicycle to see the GNA.
The WCU All Stops Shuttle Bus will take you to R Lot, if you let the driver know that you want to go there. And the Q Lot Express stops in Q Lot (naturally), about 300 yards from the main entrance to the GNA.
Four parking spaces are available specifically for the GNA (no WCU parking permit required).
Once You're There
To promote access to the GNA, the University maintains a network of trails throughout the preserve:
A pdf version of the map is available here .
In order to help maintain the GNA in the best possible condition, to protect the GNA's wildlife and plant life, and to minimize disruption to ongoing research, visitors are asked to observe the following regulations:
- The GNA is open only from dawn to dusk
- Please stay on marked trails only
- Pets must be on a leash (6 ft., or shorter, please)
- Please clean up after your pet and put the waste in the trash receptacle
- No fires (including smoking)
- No camping
- No fishing or hunting
- No moving, damaging, or collecting plants, animals, or natural objects
- No bikes or motorized vehicles
- No littering
- No alcoholic beverages
Thank you for respecting the Gordon by following these regulations.
If you have any questions or comments, please contact us.
Beginning in the winter of 2015-16, long-time student intern and GNA Assistant Stewardship
Manager, Kendra McMillin placed a 'Visitor's Log' at the kiosk at the main entrance.
We love to read people's comments, and we also maintain a photo archive of the entries.
Below, are some of our favorite comments with a transcription of the comment in the adjoining column. Note: You can click on the image to see a larger version.
"One of my last hikes a student at WCU; graduating in two months! I LOVE this place!
I hope the GNA stays protected and cared for for decades to come! I have used this
place to hike, read, meditate, and learn about native plants and animals. I came
here my first day as a first-year student and I plan on hiking here the day I graduate."

“I walk here from the Borough. When I’m in the Natural Area, I walk briskly for exercise and slowly through the trails. I really enjoy listening, observing the birds and stream. I also like noticing the changes in the trees, bushes, and even the footprints. I just noticed the tree guide. I’m thinking of asking a friend to come back here and check out the Tree ID walk. Good place!”
“Wow! I’ve lived in West Chester for 10 years and this is my first time on these beautiful trails! Amazing!”
"I came to a turn south of the football stadium on New St. and it made all the difference … I went to WCU and graduated in 1981. Always loved these woods. Great place to absorb the beauty and tranquility of the woods, and enjoy the aloneness or the company of your dogs/ friends.”
“Rainy again, but perfect weather for walking the woods to observe nature’s splendor and hear all the birds happy for spring. I am a professional horticulturist, and another horticulturist introduced me to this place- everything here is great to immerse oneself for ‘green bathing.’ I am always on the hunt for local natural treasures for inspiration for my job in naturalistic gardening and to grow in my own understanding of this natural world which has existed without us for so long- it’s a challenge worth contemplating how we fit in the system as another helpful “cog” in the wheel. Thank you for having the inspiration and fore thought to keep this in its natural state for all-especially in a world where this is becoming rarer by the day."
“We need more places like this in West Chester. Such an awesome place to escape.”
