<font size="2" face="verdana,arial,helvetica">garyk - yes, large woody debris in the creek is an important component of fish habitat...so is shade on the creek. But shade from old growth trees is no better than shade from young alders or salmonberry. Using a spherical densiometer, I conducted measurements of % shading on 10 salmon creeks in the Siuslaw drainage in 1994...one of the poorest (lowest percentage of the creek actually shaded) was on Saleratus Creek where it flowed thru a 1/2 mile long stretch of BLM oldgrowth. Due to gaps in the canopy the creek had only about 45% shade compared to 95+% for creeks with young alder canopies (I know, young alder makes poor LWD...but we're talking about shade here).Originally posted by garyk:
......the water shaded by centuries old fir, spruce and cedar. It’s completely unlike the rest of Tillamook’s other rivers.
Its too bad some fry & smolt counts aren't readily available for a stream with 0% oldgrowth...contrasted with one that is 100% oldgrowth/unroaded/undeveloped.
DepoeBayDan - I wish I could have mede the trip but your report w/pics makes it seem like I was there anyway. :wink:
