Trait velocities reveal that mortality has driven widespread coordinated shifts in forest hydraulic trait composition

Publications Posted on: June 20, 2020
Understanding the driving mechanisms behind existing patterns of vegetation hydraulic traits and community trait diversity is critical for advancing predictions of the terrestrial carbon cycle because hydraulic traits affect both ecosystem and Earth system responses to changing water availability.

Effect of tree layer and microsite on the variability of natural regeneration in autochthonous beech forests

Publications Posted on: April 02, 2020
The present study describes natural regeneration on five permanent research plots (PRP) in juvenile growth and development phases (regrowth and advanced growth) in autochthonous beech forests in Broumovské stěny National Nature Reserve located in the Protected Landscape area in the northeast part of Czech Republic. The stands of herb-rich beech forests were studied in the optimum to break-up stage.

Effects of diversity of tree species and size on forest basal area growth, recruitment, and mortality

Publications Posted on: March 04, 2020
The objective of this study was to determine the relationship, or lack thereof, between growth and diversity of tree species and size in conifer stands of western North America. Growth was measured by net basal area growth and its components: survivor growth, recruitment, and mortality.

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.

Regional data to support biodiversity assessments: terrestrial vertebrate and butterfly data from the Southwest

Publications Posted on: December 03, 2019
Spatially explicit data on the location of species across broad geographic areas greatly facilitate effective conservation planning on lands managed for multiple uses. The importance of these data notwithstanding, our knowledge about the geography of biodiversity is remarkably incomplete.

Does burn severity affect plant community diversity and composition in mixed conifer forests of the United States Intermountain West one decade post fire?

Publications Posted on: September 14, 2019
Background: Wildfire is an important ecological process in mixed conifer forests of the Intermountain West region of the USA. However, researchers and managers are concerned because climate warming has led to increased fire activity in recent decades.

Long-term vegetation response following post-fire straw mulching

Publications Posted on: September 14, 2019
Background: Straw mulching is one of the most common treatments applied immediately post fire to reduce soil erosion potential and mitigate post-fire effects on water quality, downstream property, and infrastructure, but little is known about the long-term effects on vegetation response. We sampled six fires that were mulched between 9 and 13 years ago in western US dry conifer forests.

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.

Faunal characteristics of the Southern Rocky Mountains of New Mexico: implications for biodiversity analysis and assessment

Publications Posted on: May 12, 2016
To define the faunal context within which local and regional resource management decisions are made, conservation of biological diversity requires an understanding of regional species occurrence patterns. Our study focused on the Southern Rocky Mountains of New Mexico and included the San Juan, the Sangre de Cristo, and the Jemez Mountains.

Vegetation response after post-fire mulching and native grass seeding

Publications Posted on: July 08, 2015
Post-fire mulch and seeding treatments, often applied on steep, severely burned slopes immediately after large wildfires, are meant to reduce the potential of erosion and establishment of invasive plants, especially non-native plants, that could threaten values at risk. However, the effects of these treatments on native vegetation response post fire are little studied, especially beyond one to two years.
