Research Shows Thinning Benefits Bees, Forests
Researchers in Colorado over a 10 year period have determined that forest thinning opens up canopies and benefits key tree pollinators by allowing more flower and shrub species that attract and sustain bee populations. Biologists from Colorado State and Utah State studied 15 thinned and 15 unthinned forest plots and found more species diversity and better overall forest health in the thinned tracts.
The researchers were also able to identify key pollinator plant species such as blue mist penstemon, field chickweed, pineywoods geranium and others and recommend that resource managers seed forests with them to promote a robust pollinator network that benefits all plant species.

Study Shows Site, Rotation Affects Carbon Sequestration Rate
Forest modeling research at Oregon State University’s College of Forestry shows a tract’s productivity is the top factor determining the rotation time that allows for the most above-ground carbon sequestration. Using OSU’s 11,000 acre McDonald-Dunn Research Forest as a study area, researchers inventoried more than 300 tracts known from past activities that varied widely in productivity levels. The data was run through modeling software that predicts changes in vegetation due to natural disturbances or management activities…
