Wooded Ravines

Approximately 15.4 non-continuous acres

Summary Assessment
Ravines at the Lynn Farm are semi-wooded, featuring narrowly branched, smaller-stem native trees. Ravine slopes were selectively logged while ravine bottoms were partially disturbed (wetland buffers within the ravines do not appear to have been systematically observed). The western wooded ravine appears the least disturbed by recent logging. 

Native sedges, rushes, and warm season grasses have a moderate patchy presence in the ravine understory, with occasional native ferns, woodland wildflowers,
shrubs, and tree seedlings. The invasive exotic annual Japanese Stiltgrass (Microstegium viminium) is abundant in ravine bottoms. Other invasive exotic vegetation includes occasional Small Carpetgrass (Arthraxon hispidus) and spotty occurrences of immature Multiflora Rose shrub (Rosa multiflora). 

Deer are intensively browsing certain groundplane vegetation, particularly American Holly (Ilex opaca) stump sprouts.

Spur of Central Wooded Ravine #2, June 2016. Groundplane vegetation is fairly sparse on ravine slopes, as evident above. While the ravine bottoms were not logged, increased light and wind levels caused by cutting nearby and increased water flows from disturbed uplands likely contributed to proliferation of invasive exotic vegetation (such as Japanese Stiltgrass) in ravine lowlands.
Western Wooded Ravine, July 2016. In some areas, the woodland understory is fairly depauperate, perhaps due to deer browse and seed predation over time.
Sedge Knoll, Western Wooded Ravine, July 2016. Woodland herbaceous growth found in significant abundance tends to consist of browse-resistant species, such as this matrix of native sedges (Carex spp.)

Restoration & Management Implications
• Composition of woodland edge vegetation and expanding woodland cover will be key to reducing the negative effects of increased light and wind levels on remaining wooded areas.
• Control of Japanese Stiltgrass and Small Carpetgrass will be critical to vegetation diversity and preventing these problem species from expanding into adjacent
areas disturbed by logging. Where broadscale weed control occurs, spot seeding will help stabilize treated areas by competing with weedy regrowth
and reducing chances for erosion.
• Spot seeding on slopes with sparse or absent vegetation will help prevent against erosion.
