Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN STYLE="font-style:italic;"><SPAN>The FP Minimum Canopy Cover layer provides the minimum percentage of Canopy Cover Required as outlined in FP Board Manual 1 for use when timber harvest is proposed within 75 feet of the bankfull width (BFW) or channel migration zone (CMZ) on flowing S or F streams or, in the case of exempt 20-acre parcel, harvest proposed within the maximum width Riparian Management Zone as described in WAC 222-30-023. The data in the layer is based on the temperature method which is described in Board Manual 1 and uses location (Eastern or Western WA), the water quality stream temperature classification 16 or 18 degrees Celsius, elevation and equations derived from the nomographs included in the Board Manual. The results provided for Minimum Canopy Cover GIS layer, also referred to as Minimum Required Shade, will produce the same results as using the method described in the Board Manual. The layer provides the Minimum Canopy Cover only on managed timber land. The layer excludes federal and tribal lands, as well as some land in the Columbia Plateau which does not support commercial timber. The layer also excludes lands in the Bull Trout Overlay (BTO) because, as outlined in WAC and the Board Manual, all available shade must be retained with 75 feet of the bankfull width or channel migration zone (CMZ) in the BTO. Additional information on shade requirements can be found in the following WACs: WAC 222-30-021, 222-30-022, 222-30-023 and 222-30-040. The information in this layer can be used to ensure post-harvest conditions are in compliance with rules ensuring adequate shade on flowing F and S streams. The Minimum Shade Required percentage is required, under certain circumstances, to be added to FPA questions 23 and 25, as applicable. </SPAN></SPAN></P></DIV></DIV></DIV>
