Under Maryland State Highway Association’s first full-delivery contract for stream restoration services, Wildlands completed construction on the Marylea Farm Stream Restoration project in Harford County, MD in May 2020. The project restored 9,470 linear feet of stream on Thomas Run and three unnamed tributaries in the Chesapeake Bay Watershed. Thomas Run and its tributaries are classified as “recreational trout waters,” so the design of Thomas Run and the lower gradient tributary reaches consisted of riffles and pools that incorporate large woody debris, boulders, brush, and lunker structures to enhance aquatic habitat. The steeper tributary reaches incorporate boulder steps and cascades with deep pools to provide additional aquatic habitat.
The 32-acre conservation easement preserves four archaeological sites containing Native American artifacts as well as existing wetlands, some of which provide potential habitat for the northern bog turtle. The riparian buffer was planted along the stream channels with early successional native vegetation comprised of trees, shrubs, and herbaceous species. Small areas around the planting perimeter were seeded with native wildflowers to provide habitat for the monarch butterflies, which were prevalent at the site preconstruction. By closeout, the project will provide 9,885 credits towards the State Highway Administration’s program to comply with the Chesapeake Bay TMDL and their MS4 permit.
