Context:
Forests cover nearly half of Kentucky’s land area, and timber harvesting is a critical component of the state’s rural economy. However, traditional logging operations often require stream crossings that can contribute to sedimentation, erosion, and long-term water quality degradation—especially in Eastern Kentucky’s steep terrain. Many small and underserved logging operations lack the resources or equipment to install elevated, BMP-compliant crossings. In response to these challenges, the Kentucky Logging Bridge Program was launched by the University of Kentucky Department of Forestry and Natural Resources in partnership with the Kentucky Master Logger Program, with funding from the U.S. Forest Service.
Response:
To address sedimentation from stream crossings, the Kentucky Logging Bridge Program introduced a temporary bridge access initiative using rent-to-own solid oak timber mats. These bridges allow loggers to cross streams without disturbing the channel or banks, dramatically reducing runoff and sedimentation. The program provided loggers with access to affordable, BMP-compliant bridges, along with education, field demonstrations, and hands-on training. Bridge locations were tracked using an interactive web-based mapping platform to monitor installations and stream impact. The program specifically targeted underserved operators and forest landowners to ensure broad access and conservation benefits across Kentucky.
Results/Impact:
In its first year, the program deployed 68 temporary bridges across 21 counties, resulting in an estimated reduction of 30,000 plus kg of sediment from entering Kentucky’s waterways based on modeled BMP performance metrics. Several participants noted improved operational efficiency and reduced downtime during wet weather, allowing them to access otherwise unreachable timber tracts.
Public Value:
This program demonstrates how practical, science-based solutions can protect Kentucky’s natural resources while supporting rural livelihoods. By reducing sedimentation and streambed disruption, the bridges protect aquatic habitats and drinking water sources. At the same time, loggers gain access to affordable infrastructure that supports long-term economic viability and adherence to environmental regulations. The project strengthens Kentucky’s position as a leader in sustainable forestry while building local capacity through education and innovation.
