A novel approach to spatially assessing instream woody habitat densities across large areas

A bound kernel density estimate (BKDE) analysis was performed using the IWH point locations, weighted by an average volume inferred from the point size and complexity values. A fine scale map is obtained providing a continuous representation of IWH densities (m3 m−2) indicating a high degree of IWH density variability along the river. The relative high resolution map is produced for habitat restoration managers to assess river sections generally less than 1 km long for IWH reintroduction.
