Partial Open Woodlands
Approximately 7.5 non-continuous acres
Partial Open Woodland areas at the Lynn Farm feature large, broadly branched mature trees (including Oaks, Sweet Gum, and Tulip Poplar) with a grassy understory and occasional native wildflowers, ferns, sedges, and tree seedlings. The exotic annual Japanese Stiltgrass (Microstegium vimineum) is abundant throughout, with the greatest concentration in the easternmost Partial Open Woodland. Less abundant, scattered invasive exotics include the perennial Beefsteak Plant (Perilla frutescens), the annual Small Carpetgrass (Arthraxon hispidus), Japanese Honeysuckle vine (Lonicera japonica), and immature Multiflora Rose (Rosa multiflora).
These open woodland areas are characterized primarily by upland conditions, although there are gentle depressions and a constructed pond in the Eastern Partial Open Woodland.
Minimal logging appears to have occurred in these areas, although small-scale selective cutting may have occurred within the past 10-20 years as evidenced by moss-covered stumps in the easternmost Partial Open Woodland. Animals were also likely pastured in the easternmost Partial Open Woodland within the last several decades, further contributing to the disturbed character of groundplane growth there.
Eastern Partial Open Woodland, June 2016. Partial Open Woodland areas are characterized by large, broadly branched mature trees with a grassy understory largely absent of shrubs. The composition of groundplane vegetation and the broadly branched trees indicate that these semi-wooded areas were kept fairly open for an extended period of time, presumably as pasture with occasional cutting of trees for firewood or other farm-type uses.
Restoration & Management Implications
•Control of problem weeds (particularly in the eastern savanna) will be critical to preventing these weeds from expanding into adjacent areas disturbed by logging. When broadcast weed control occurs, spot seeding will help stabilize treated areas by competing with weedy regrowth and reducing chances for erosion.
•Areas of especially weedy groundplane vegetation could serve as alternative locations for a research building complex or for other intensive human uses.
