Wooly Bugger Farm - Restoration Project
The Piney Run stream, wetland, and woodland restoration project converts 54 acres of steep eroding agricultural land to woodland, restores almost 2,500 linear feet of stream within a brook trout watershed, and restores historic water tables and wetland function to over 6 acres of non-tidal riparian wetlands. The project is situated within northern Baltimore County, Maryland and consists of headwater tributaries to Piney Run, an important and high quality tributary to the Loch Raven Reservoir subwatershed and overall Gunpowder River watershed. The project serves as a consolidated mitigation site providing wetland and forest credits to public and private entities such as local developers, Baltimore County Department of Public Works, and Aberdeen Proving Ground.
The forest component, completed in April 2008, consisted of planting 28.2 acres of upland and riparian hardwood forest and preserving 21.6 acres of existing hardwood forest. The planting was completed in rows, with a spacing of 11 feet to allow ample access for maintenance and to provide a density of 350 stems per acre. The planting areas were laid out on the property to allow for future small agricultural uses and for access to wetland and stream restoration areas proposed as phase II of the project. Immediately after planting Ecotone began implementing an invasive species management plans entailing periodic mowing to suppress invasive species coupled with selective broadleaf herbicide treatments where necessary.
In April 2012 Ecotone completed construction for the 2,500 linear feet of stream and over 5 acres of wetland restoration. The design called for raising the invert of the stream channel and excavation/removal of legacy sediments on the floodplain to create a connected stream and riparian wetland complex. Design elements for the stream restoration component of the project include the removal of three culverts to provide passage for aquatic organisms, creation of step pool morphology, riffle grade control structures, and the use of log and willow cutting bank stabilization structures to provide stability and habitat for brown trout. Wetland and floodplain areas will be planted with native hardwood trees and shrubs to create a diverse habitat area.
Pre-construction: Incised channel with legacy sediments.
Summer 2008: Upland reforestation.
1 year post construction: Step Pool transition.
