•The national BMP implementation rate was 91% (32 states reported data).•State BMP regulation did not have an effect on mean state implementation rates.•Mean state BMP implementation rates were lower for the northeastern region.•Thirty-three states reported having conducted BMP effectiveness studies.•Twenty-five states written or revised BMP guidelines within five years of the survey. United States forestry best management practices (BMPs) were developed by U.S. states to protect water quality while enhancing the sustainability of forest management activities. Forestry BMPs are revised over time or new BMPs are written to meet current water quality standards. Properly implemented forestry BMPs have been found to minimize the impact of erosion and sediment that may occur during forest management activities. States developed implementation strategies to help determine if BMPs are being implemented correctly; however, these strategies can vary between regions and states making implementation results difficult to interpret. Few studies have compared monitoring strategies and implementation of BMPs on a national level. This study surveyed and received responses from state forestry agencies in all 50 states. Each state reported a documented BMP manual. Twenty states reported non-regulatory BMP guidelines, 19 reported quasi-regulatory BMP guidelines, and 11 reported regulatory BMP guidelines. Thirty-nine states have BMP monitoring programs with the state forestry agency as the lead agency in 35 states. BMP effectiveness studies were reported in 33 states with 19 states reporting current or future effectiveness studies. Thirty-two states reported that they have conducted BMP implementation studies resulting in a mean national BMP implementation rate of 91%. However, when evaluating implementation of individual BMP categories, the survey indicated potential deficiencies for some states, yet these states’ overall BMP implementation rate appear to be satisfactory. There was no significant difference between non-regulatory, quasi-regulatory, and regulatory BMP guidelines when compared by mean state BMP implementation rates (90.2%, 90.2%, and 93.4%, respectively). Mean BMP implementation rates for the western (93.2%) and southeastern (92.4%) regions were significantly higher than the northeastern region (86.4%). This assessment of state BMP programs indicates that BMP programs appear to be implemented at relatively high levels across the U.S. These findings should be useful globally for agency managers to improve program effectiveness and better understand BMP implementation and program structure among 50 diverse states.
