Delaware timber harvests achieved a 93 percent rate of compliance with best management practices (BMPs) designed to protect water quality and limit soil erosion, according to a new report. Dr. Anne Hairston-Strang, a forest hydrologist with the Maryland DNR Forest Service, assessed the use and effectiveness of BMPs by surveying a total of 72 sites in Maryland and Delaware from 2014 to 2016. Selected sites were locations with waterway crossings and buffers with the greatest potential for water quality impacts. Effects were expected to be larger than normal because high rainfall during the 2014-2016 period represented an increase of 20 percent above the 30-year average. Final data indicated that the average sediment delivery across all locations was less than one cubic foot per site—indicating that proper use of BMPs was successful at protecting water quality during harvest operations.
