The ideological conflict over clearcutting has led many coastal forestry operations to harvest timber using alternatives to clearcutting, especially variable retention. But there is little solid research information to guide the way for policy, regulation and guidelines relating to partial cutting. The STEMS project is a large-scale, multi-disciplinary experiment that compares forest productivity (including studies on residual tree growth/mortality/windthrow/harvest damage, light/regeneration/understory vegetation relationships, coarse woody debris inputs, and soil disturbance/compaction), economics and public perception of 7 silvicultural systems. The seven treatments will be replicated at three locations. This kind of large-scale, replicated field experiment will improve environmental management and policies because results can be directly interpreted at an operational scale due to the large-scale experimental design. The first replication has been established in the Snowden Demonstration Forest. Funding is requested for data collection at the first replication (STEMS 1) and to establish the second replication (STEMS 2).
