Best Management Practices for Drainage Maintenance Works in Oregon Spotted Frog Habitat

Stream channel maintenance works are required to reduce flooding and maintain drainage for farmland. Works have traditionally used excavators with sloped buckets to dredge vegetation within watercourses. However dredging is considered the most adverse and harmful method for maintaining a watercourse due to its significant negative impacts on fish and wildlife habitat. The Oregon Spotted Frog Recovery Team recognizes that drainage maintenance works on active farmland areas are necessary to reduce flooding and crop damage, and is committed to working with municipalities to ensure that channel maintenance works in known and suspected Oregon Spotted Frog habitats are as efficient and harmless as possible. This is a living document that may change based on the availability of new information regarding frog habitat requirements, drainage needs and maintenance techniques.
