Vegetation and ecological characteristics of mixed-conifer and Red Fir forests at the Teakettle Experimental Forest

Creator:: North, Malcolm, Oakley, Brian, Chen, Jiquan, Erickson, Heather, Gray, Andrew, Izzo, Antonio, Johnson, Dale, Ma, Siyan, Marra, Jim, Meyers, Marc, Purcell, Kathryn, Rambo, Tom, Rizzo, Dave, Roath, Brent, and Schowalter, Tim
Abstract:: Detailed analysis of mixed-conifer and red fir forests were made from extensive, large vegetation sampling, systematically conducted throughout the Teakettle Experimental Forest. Mixed conifer is characterized by distinct patch conditions of closed-canopy tree clusters, persistent gaps and shrub thickets. This heterogeneous spatial structure provides contrasting microclimate, habitat and resource conditions...

Fire ecology of ponderosa pine and the rebuilding of fire-resilient ponderosa pine ecosystems

Creator:: Fitzgerald, Stephen Arthur
Abstract:: The ponderosa pine ecosystem of the West have changed dramatically since Euro-American settlement 140 years ago due to past land uses and the curtailment of natural fire. Today, ponderosa pine forests contain over abundance of fuel, and stand densities have increased from a grange of 49-124 trees per ha (20-50...

Wildlife habitats in managed rangelands : the Great Basin of southeastern Oregon

Creator:: Hall, Frederick C.
Abstract:: Management practices and options to provide habitat for wildlife in the Great Basin of southeastern Oregon deal with both vegetation treatment and protection, livestock management, maintenance or distribution of water developments, protection of wildlife areas through road closures or fencing, and direct manipulation of wildlife through hunting, trapping, or other...

A pioneer exotic tree search for the douglas fir region

Creator:: Silen, Roy R. and Olson, Donald L.
Abstract:: After three-quarters of a century of introduction of 152 conifer and broadleaf species, no promising candidate exotic was found for the Douglas-fir region. Growth curves spanning 50 years or longer are figured for many species. Firs, pines, larches, spruces, hemlocks, and cedars originating in northwestern North America had superior growth...

Forest habitat types on the Medicine Bow National Forest, southeastern Wyoming : preliminary report

Creator:: Wirsing, John M. and Alexander, Robert R.
Abstract:: A vegetation classification based on concepts and methods developed by Daubenmire was used to identify five habitat types and their related phases on the Medicine Bow National Forest: Abies lasiocarpa/Vaccinium scoparium, including the Pinus contorta/Vaccinium scoparium community; Abies lasiocarpa/Carex geyeri, including the Pinus contorta/Carex geyeri community; Populus tremuloides/Carex geyeri; Pinus...

Genetic variation in Douglas-fir : a 20-year test of provenances in eastern Nebraska

Creator:: Van Haverbeke, David F., 1928-
Abstract:: Twenty-year-old Douglas-fir trees in provenances from Arizona, New Mexico, and southern Colorado survived better and grew taller; but incurred more winter injury in eastern Nebraska than trees from provenances from northern Colorado, southern and western Montana, northern Idaho, Canada, and eastern Washington. However, surviving trees from Pacific Coast, and northern...
