In the fall of 2014 the Highland Park Regional Chapter of the Native Plant Society of New Jersey took a field trip to Environmental Education Center at Lord Stirling Park.Towards the end of the walk Park Ranger Maria Rossi invited us into one of two seven year old deer exclosures where we began a search for native plants. We discovered quite a few and decided to return in the spring to conduct plant surveys of both exclosures.
On May 10, 2015 between 2pm and 4pm, the chapter surveyed the West deer exclosure and recorded about 40 plant species. The list below contains more native species than introduced ones. Black cherry (Prunus serotina) and hickory (Carya) were the most common tree saplings seen. There were some dogwood (Cornus), elm (Ulmus) and oak (Quercus) saplings. We saw dense clumps of Jack-in-the-pulpit (Arisaema triphyllum), jewelweed (Impatiens capensis), Canada mayflower(Maianthemum canadense) and spring beauties (Claytonia virginica). The West exclosure measures approximately 100' x 80'.
One can see how effective the deer exclosure is when comparing the inside of the exclosure to the outside. There is a lack of understory in those parts of the woods where deer consume most of the native shrubs and tree saplings growing outside the exclosure.
Participants braving the bugs.
We will survey the East exclosure this summer. If you are interested in participating contact Mary and Belinda at highlandpark@npsnj.org
The enclosure was divided into 5 sections and labeled A to E. An estimate was made of the amount in each section.
