Vegetation structure and composition in the Shoshone Mountains and Toiyabe, Toquima, and Monitor ranges, Nevada (2nd Edition)

Datasets Posted on: August 27, 2015
These data document vegetation structure (trees, shrubs, and ground cover), composition of trees and shrubs (in most cases, ground cover is differentiated by functional group but not by species), and presence or absence of cheatgrass (Bromus tectorum) in canyons throughout four mountain ranges in the central Great Basin (Lander, Nye, and Eureka counties, Nevada): the Shoshone Mountains, Toiyabe Range, Toquima Range, and Monitor Range.

Detections of breeding birds in the Shoshone, Toiyabe, Toquima, and Monitor ranges, Nevada (3rd Edition)

Datasets Posted on: August 27, 2015
These data document annual detections of breeding birds in canyons throughout four mountain ranges in the central Great Basin (Lander, Nye, and Eureka counties, Nevada): the Shoshone Mountains, Toiyabe Range, Toquima Range, and Monitor Range. Data were collected during the breeding season from 2001 through 2014, inclusive. Birds were detected during fixed-radius point counts.

Data product containing tree heights, survival, and genetic variation for "Genetic Variation in Ponderosa Pine: A 15-year Test of Provenances in the Great Plains"

Datasets Posted on: March 27, 2015
Seeds from 79 natural stands throughout the ponderosa pine range, both east and west of the Continental Divide, were sown and grown in a nursery for three to four years in the 1960's. These seeds were then distributed to plantations, mostly in the Great Plains. This dataset contains the height of the surviving trees after 15 years for 14 plantations.

Data product containing 22-year Nebraska tree heights, survival, and genetic variation for "Ten-Year Performance of Ponderosa Pine Provenances in the Great Plains of North America"

Datasets Posted on: March 27, 2015
Seeds from 79 natural stands throughout the ponderosa pine range, both east and west of the Continental Divide, were sown and grown in a nursery for three to four years in the 1960's. Some of these seeds were then distributed to three different field plantations in Alliance, Hastings, and Plattsmouth Nebraska. These datasets contain individual tree heights of surviving trees, taken at various frequencies from 1968 to 1987.

Data product containing campsite assessments for "Effectiveness of a Confinement Strategy in Reducing Pack Stock Impacts at Campsites in the Selway-Bitterroot Wilderness, Idaho"

Datasets Posted on: March 27, 2015
Measurements of ground cover conditions, tree impacts, and campsite conditions were taken in the Seven Lakes Basin in the Selway-Bitterroot Wilderness between 1993 and 1998 in order to assess bringing high levels of campsite impact into compliance with management standards.

Data product containing 20-year tree heights, diameters, and genetic variation for "Scots Pine in Eastern Nebraska: A Provenance Study"

Datasets Posted on: March 27, 2015
Seedling progenies of 36 rangewide provenances of Scots Pine (Pinus sylvetris) were established in a field test at Horning State Farm experimental area near Plattsmouth, Nebraska in April of 1962. Tree heights were measured at the end of each growing season from 1963 through 1969, and again in 1971. Tree height and diameter at breast height were both measured at the end of the growing season in 1976, 1978, 1979, and 1981.

Mountain hemlock tree-ring width chronologies from the western Oregon Cascade Mountains

Datasets Posted on: March 27, 2015
This data publication contains times series of measured ring widths from increment cores collected from mountain hemlock trees at three sites in the Three Sisters Wilderness Area in the west central Cascade Mountains of Oregon.

Vegetation structure and composition in the Shoshone Mountains and Toiyabe, Toquima, and Monitor ranges, Nevada

Datasets Posted on: March 27, 2015
These data document vegetation structure and composition of trees and shrubs in canyons throughout four mountain ranges in the central Great Basin (Lander, Nye, and Eureka counties, Nevada): the Shoshone Mountains, Toiyabe Range, Toquima Range, and Monitor Range.

Tenderfoot Creek Research Project seedling, sapling and variable radius plot tree data

Datasets Posted on: March 27, 2015
This data publication contains seedling density, sapling density and variable plot radius tree data associated with the Tenderfoot Creek Research Project sampled between 1997 and 2007. Experimental shelterwood harvests combined with prescribed burning were implemented in the Tenderfoot Creek Experimental Forest between 1999 and 2003. These data contain pre- and post-treatment data.

Field measurements of ground, surface, ladder, and crown fuels 2-32 years following Dendroctonus ponderosae epidemics in the Pinus contorta zone of south-central Oregon

Datasets Posted on: March 27, 2015
Mountain pine beetle (Dendroctonus ponderosae, MPB), a bark beetle native to the western North America, has caused vast areas of tree mortality over the last several decades. The majority of this mortality has been in lodgepole pine forests (Pinus contorta) and has heightened concerns over the potential for extreme fire behavior across large landscapes as forest structure and fuels are altered following these MPB epidemics.
