FORCE has a record of undertaking surveys both directly or with partners to ascertain the status of wildlife in the River Crane. Some surveys are driven directly by incidents such as the catastrophic water pollution in 2011. Others are driven by a wish to understand the quality and quantity of the wildife in the river environment e.g. bats, small mammals, etc which help FORCE to understand the impact of urban traits in the catchment area. Some of these reports are commissioned directly by FORCE whereas others have been prepared by partners or are in the public domain.
