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.

Fire patterns in piñon and juniper land cover types in the Semiarid Western United States from 1984 through 2013

Publications Posted on: February 07, 2018
Increases in area burned and fire size have been reported across a wide range of forest and shrubland types in the Western United States in recent decades, but little is known about potential changes in fire regimes of piñon and juniper land cover types.

Pretreatment tree dominance and conifer removal treatments affect plant succession in sagebrush communities

Publications Posted on: November 13, 2017
In sagebrush (Artemisia tridentata Nutt.) ecosystems, expansion and infilling of conifers decreases the abundance of understory perennial vegetation and lowers ecosystem resilience and resistance of the once shrub grass−dominated state. We prescribed burned or cut juniper (Juniperus spp. L.) and pinyon (Pinus spp. L.) trees at 10 sites across the western United States.

Post-fire vegetation response at the woodland-shrubland interface is mediated by the pre-fire community

Understanding the drivers of ecosystem responses to disturbance is essential for management aimed at maintaining or restoring ecosystem processes and services, especially where invasive species respond strongly to disturbance.

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

Publications Posted on: May 12, 2016
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.

Presence and absence of butterflies in the Shoshone Mountains and Toiyabe and Toquima ranges, Nevada

Datasets Posted on: August 27, 2015
These data document annual observed presences and absences of resident butterflies in canyons throughout three mountain ranges in the central Great Basin (Lander and Nye counties, Nevada): the Shoshone Mountains, Toiyabe Range, and Toquima Range. Data were collected from 1995 through 2003, inclusive.

Detections of breeding birds in the Shoshone, Toiyabe, Toquima, and Monitor ranges, Nevada

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 from 2001 through 2009, inclusive. Birds were detected during fixed-radius point counts. Each point was visited three times per season.

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.

Detections of breeding birds in the Shoshone, Toiyabe, Toquima, and Monitor ranges, Nevada (2nd 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 from 2001 through 2012, inclusive. Birds were detected during fixed-radius point counts. In most cases, each point was visited three times per season.
