The sub9roup tirst focused on how . block <br />habitat manaqement ar.a could be developed in each bridge seqment <br />between Lexinqton and Chapman, HE. This was done by observing <br />aerial photos and the GIS land resource maps developed by the <br />Trust. The qroup looked for wet meadow tracts classified on the <br />GIS land resource maps and simply .elected one to analyze <br />potential management areas. Based on this approach, . table of <br />acreaqes were deVeloped that included wet meadows, river channel <br />. and buffer. For the wet meadow and river channel acreage., II. <br />break down was made of present lands and those that needed to be <br />converted. For example, the present channel may be only 600 feet <br />wide which would equate to approxaately 145 acre. in a two mile <br />reach ot river. Therefore, to have Dpti1llU1ll roosting width of <br />1150 feet, 550 feet of channel would n8ed to he developed by <br />converting islands and weoded floodplain into open channel fer an <br />increue of approximately 133 acr.. in a two mile reach.
