Detections of breeding birds in the Shoshone, Toiyabe, Toquima, and Monitor ranges, Nevada (4th Edition)

Datasets Posted on: December 30, 2020
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 2015, inclusive, and in 2018 and 2019. Birds were detected during fixed-radius point counts.

Incidental and long-distance bird observations in the Shoshone, Toiyabe, Toquima, and Monitor ranges, Nevada (3rd Edition)

Datasets Posted on: December 30, 2020
These data document detections of 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. A small number of detections were made in the valleys adjacent to these mountain ranges and in the Desatoya Range. Data were collected during the breeding season from 2002 through 2015, inclusive, and in 2018 and 2019.

Long-term effects of tree expansion and reduction on soil climate in a semiarid ecosystem

Publications Posted on: September 29, 2020
In sagebrush ecosystems, pinyon and juniper tree expansion reduces water available to perennial shrubs and herbs. We measured soil water matric potential and temperatures at 13-30 and 50-65 cm soil depths in untreated and treated plots across a range of environmental conditions. We sought to determine the effects of tree expansion, tree reduction treatments, and expansion phase at time of treatment over 12-13 yr post-treatment.

Dynamics of a pinyon-juniper stand in northern Arizona: a half-century history

Publications Posted on: June 22, 2020
This paper adds to the limited knowledge of stand dynamics in pinyon-juniper woodlands by reporting on the changes in species composition, numbers of trees, arrangements of trees, and total height and volume in a stand from late 1938 to early 1991. This information should be helpful in managing pinyon-juniper woodlands to sustain their productivity and maintain their multiple-use values.

New California Plateaus Science Synthesis: Science Supporting Dry Forest and Rangeland Planning

Documents and Media Posted on: June 08, 2020
The newly published RMRS-GTR-409 has a Northeastern California focus on sagebrush rangeland, dry pine forestland, juniper forests, habitat and wildlife, society, and response to disturbances, particularly those related to climate. Document Type: Other Documents

Plateaus science synthesis: A scientific foundation for future land management planning

Science Spotlights Posted on: May 08, 2020
The new publication, Northeastern California plateaus bioregion science synthesis (Gen. Tech. Rep. RMRS-GTR-409), has a northeastern California focus on sagebrush rangeland, dry pine forestland, juniper forests, habitat and wildlife, society, and response to disturbances, particularly those related to climate.

Use of pinyon-juniper woodlands by bats in New Mexico

Publications Posted on: February 27, 2020
In recent years, the demand has grown for information on how to conserve bat populations in forested ecosystems. Many researchers have responded with studies of bats in forests, but few have studied bat communities in arid-adapted forest types, such as pinyon-juniper woodlands, which are widespread and abundant throughout the west.

The ecology, history, ecohydrology, and management of pinyon and juniper woodlands in the Great Basin and Northern Colorado Plateau of the western United States

Publications Posted on: January 30, 2020
This synthesis reviews current knowledge of pinyon and juniper ecosystems, in both persistent and newly expanded woodlands, for managers, researchers, and the interested public. We draw from a large volume of research papers to centralize information on these semiarid woodlands. The first section includes a general description of both the Great Basin and northern Colorado Plateau.

Seeding native species to promote ecosystem recovery after fire

Science Spotlights Posted on: July 24, 2019
The use of prescribed fire to reduce expansion of pinyon and juniper to sagebrush ecosystems is a commonly used by managers but can have unwanted consequences. In this Joint Fire Sciences Program Demonstration Project, we show how seeding native species after prescribed fire can decrease invasion of nonnative annual grasses in sites with low resistance.

Fire patterns in piñon and juniper in the Western United States: Trends from 1984 through 2013

Science Spotlights Posted on: May 15, 2018
Changes in fire patterns for piñon and juniper vegetation in the western United States were analyzed over a 30-year period. This is the first evaluation of its type.
