The Endangered Species Act is perhaps the most effective tool available for curtailing or halting resource development.  Having been unsuccessful in previous attempts to convince the USFWS to list the Alexander Archipelago wolf, the Queen Charlotte Goshawk, the marbled murrelet and several other species in Southeast Alaska, the Center for Biological Diversity and its co-petitioners now are attempting to have the yellow cedar listed.  While there are many reasons that the timber industry in Southeast Alaska has declined to its current low level of productivity - particularly on Tongass National Forest lands - listing the yellow cedar could finally bring it to an end.  If yellow cedar is listed under the ESA, timber harvest on state and private corporation lands will be affected along with national forest lands.
