Trails and Greenways
Trails and greenways provide enjoyable and safe options for transportation, which helps to improve air quality. Additionally, greenways prevent soil erosion and filter pollution caused by agricultural and road runoff, protecting land along rivers and streams and helping to improve water quality. This area contains resources applicable to planning, development, and maintenance of trails, greenways, and natural buffer zones within our parks.
Erosion Control During Trail Maintenance and Construction
Bureau of Trails New Hampshire, 2017
BMPs minimize the risk of sediment and other pollutants getting into waterbodies, maintain the natural flow of water in streams and wetlands, protect shoreland vegetation and provide a safe stable trail system.

Maintenance Practices and Costs of Rail-Trails
Rails to Trails Conservancy, 2015
This study presents a more comprehensive understanding of rail-trail maintenance, as has been done for other rail-trail issues such as construction costs, economic impact and rails-with-trails. Such an approach enables the rail-trail community to focus its limited resources more effectively on addressing the most critical issues.
