Projects I have participated in and examples of what happens with no management

b4thin-k09_69x.jpg Before thinning this stand had 373 trees/acre.

The basal area before thinning of 157 square feet is about double what should be on this site .
b4thin-k09_93x.jpg Many trees had been damaged by heavy wet snow storms. Tall skinny trees are broken off 10 to 20' off the ground. Smaller trees have been bent over and will eventually die.

If this burns, it will be a hot crown fire. If it does not burn, it will be a breeding ground for undesirable bark beetles.

Thinned on the left and unthinned on the right.
thinned-k-29-31x.jpg This is called thinning from below.

The small supressed and damaged trees are removed, leaving the biggest and best.
keane08-11.jpg The useable wood was skidded out using a medium sized farm tractor with a skidding winch as described in this paper."Logging Small Timber on Small Tracts with Small Equipment"
thin-l5-no-people.jpg Larger, older trees need more space between them than small, young ones.

Slash was chipped to reduce fire risk.
Thin-l2-no-people.jpg Most people prefer the look of properly thinned stands.
Rieple09_072.jpg On this south Douglas County project the wood was removed for firewood using an ATV. Slash was treated using the 'Lop & Scatter' method.

With room to grow each tree will be more resistant to insects and disease. The stand was left dense enough to be unfavorable to rapid invasion by oak brush.
DMT5x Trees heavily infected with dwarf mistletoe are more difficult to work by hand cutting and produce less useable product.
KilledByDMT6x Areas heavily infected with dwarf mistletoe over a long period build up undesirable volumes of fuel as it kills the trees.
Masticator_49x A masticator can be an economical way to remove the trees and treat the slash at the same time.
Masticator_50x The resulting material will hold soil in place. As it decays it returns nutrients to the soil and allow desirable vegetation to become established.
Snyder Mixed ponderosa pine and Douglas fir stand thinned for forest health and as a fuelbreak along road in Larimer County.
log deck Some of the trees removed during thinning operations can become logs for sale to local mills, posts, pole, and fuelwood.
cabinredtrees.jpg In Grand County the beetles have devastated unprotected trees.
across-lake-mpb.jpg Most of the mature lodgepole pine in Grand County was dead by 2010 due to the epidemic of mountain pine beetles exacerbated by drought.
