100 years of vegetation change at the Sierra Ancha Experimental Forest

Projects Posted on: March 08, 2019
This project incorporates historical data collected at the Sierra Ancha Experimental Forest nearly 100 years ago to determine how plant communities have changed over that period of time.

Physical and chemical properties of the foliage of 10 live wildland fuels

Datasets Posted on: March 15, 2018
This data package contains data from over 3000 individual fuel elements collected as part of Joint Fire Science Program (JFSP) project 11-1-4-19 "Determination of the effects of heating mechanisms and moisture content on ignition of live fuels." Data were collected each month during one of two one-year periods.

Seed and ring width data from 'Climate drivers of seed production in Picea engelmannii and response to warming temperatures in the southern Rocky Mountains'

Datasets Posted on: June 08, 2016
Seed production by Picea engelmannii was monitored at 13 plots distributed across an approximately 670 meter elevation gradient in the Fraser Experimental Forest near Fraser, Colorado. Seeds were collected annually between 1970 and 2010 from ten wire mesh seed traps located in each of the 13 plots. Annual plot level estimates of seed abundance were derived from an average value of the 10 traps.

Incidental and long-distance bird observations in the Shoshone, Toiyabe, Toquima, and Monitor ranges, Nevada

Datasets Posted on: August 27, 2015
These data document observations of birds, mostly in canyons and a small proportion in intervening valleys, 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 from 2002 through 2012, inclusive.

Incidental and long-distance bird observations in the Shoshone, Toiyabe, Toquima, and Monitor ranges, Nevada (2nd Edition)

Datasets Posted on: August 27, 2015
These data document observations of birds, mostly in canyons and a small proportion in intervening valleys, 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. A small number of observations were made in the valleys adjacent to these mountain ranges. Data were collected from 2002 through 2014, inclusive.

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.

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.
