MANAGING HIGH-ELEVATION FORESTS TO PRODUCE MATSUTAKE AND
HIGH QUALITY TIMBER
Managers at the Diamond Lake Ranger District on the Umpqua National Forest
are implementing uneven aged silvicultural prescriptions to promote forest
health and habitat for the matstutake mushroom. Uneven age prescriptions leave a
range of age and size classes for all tree species. A small helicopter was used
to harvest the Paw Chopper timber sale to minimize ground disturbance, which has
been proven to adversely affect matsutake production through the Diamond Lake
matsutake harvest study. Large Shasta red fir, the main host tree for matsutake
in the area, were left on site over the 700 acre area.
Pre-commercial thinning is
also planned to reduce natural tree regeneration densities, therefore allowing
more light to reach the forest floor. This is advantageous for matsutake
fruiting and the health and vigor of the stand. The photos below show the area
after harvest. These areas will be monitored in the future.
