The purpose of this project is to examine the effects of variable retention and clearcutting harvest techniques on canopy lichens by comparing growth rates of Lobaria spp. along transects that extend back from both 'hard' and 'soft' block boundaries into the adjacent old-growth forest. It is jointly funded by TRC Cedar Ltd. of McBride, B.C. and the Sustainable Forest Management Network. This report covers the establishment of the project in fall 2003, the first reweighing of the lichens in fall 2004, the addition of small L. pulmonaria thalli and L. retigera thalli in fall 2004, and the reweighing of the lichens in fall 2005. These new samples should strengthen the interpretation of experimental results by including a second species (L. retigera) and a different thallus size class (L. pulmonaria). This inclusion of new samples in fall 2004 was done without additional cost to TRC.
