Seed and soil dynamics in shrubland ecosystems: proceedings; 2002 August 12-16; Laramie, WY

The 38 papers in this proceedings are divided into six sections; the first includes an overview paper and documentation of the first Shrub Research Consortium Distinguished Service Award. The next four sections cluster papers on restoration and revegetation, soil and microsite requirements, germination and establishment of desired species, and community ecology of shrubland systems.

Colorado Plateau chenopod field trip

The field trip was held on June 14, 2000, in warm, dry weather. It consisted of eleven stops and additional views from the busses. Many saltbush (Atriplex) species were observed and their genetical and ecological characteristics described. In addition other chenopod shrubs and annual chenopods were observed and characterized. The field trip is described so that is can be experienced by interested parties on subsequent trips.

Habitat improvement for wildlife in North-Central Sonora, Mexico

Native vegetation of semiarid grasslands and desert ecosystems that comprise the Arbosufrutescent Desert scrub vegetation in north-central Sonora has been degraded by overgrazing, drought, farming, woodcutting, and a host of other activities over the past century.

Ecological implications of using goats for control of juniper in Texas

The Edwards Plateau region of central Texas supports a rich diversity of plants and animals. The diversity and abundance of trees and shrubs is especially noteworthy, but two species of juniper (Juniperus ashei, Juniperus pinchotii) now dominate much of the landscape. Goats are currently being recommended to control juniper infestations.

Rate of increase of redberry juniper (Juniperus pinchotii) canopy cover in western Texas: Ecological and economic implications

Redberry juniper (Juniperus pinchotii) is a major problem on Texas rangelands, yet little is known about the rate it is increasing. This study estimated long-term rates of change of redberry juniper canopy cover on undisturbed sites and adjacent sites that were either chained or grubbed at five locations in western Texas.

A yellowbrush/grass community type from the Uinta Mountains and Utah Plateaus

Ecological inventory and vegetation monitoring in the Uinta Mountains and Utah Plateaus on the Ashley National Forest and Manti-LaSal National Forest of the past several years suggest a community type in which yellowbrush (Chrysothamnus viscidiflorus ssp. lanceolatus), and slender wheatgrass (Elymus trachycaulus) are indicator species.

Mountain big sagebrush communities on the Bishop Conglomerate in the eastern Uinta Mountains

The Bishop Conglomerate forms broad, gently sloping pediments that include a mantle or veneer of coarse gravel and some cobble over underlying formations. These pediments cover large areas at the margins of the Uinta Mountains. Mountain big sagebrush (Artemisia tridentata var. pauciflora) communities cover rather large areas at the outer edge or lower end of these pediment-plains.

Mountain big sagebrush age distribution and relationships on the northern Yellowstone Winter Range

This study was conducted within the Gardiner Basin, an especially critical wintering area for native ungulates utilizing the Northern Yellowstone Winter Range. Mountain big sagebrush plants on 33 sites were classified as large (≥22 cm canopy cover), small (

Plant diversity at Box-Death Hollow Wilderness Area, Garfield County, Utah

"The Box" is a canyon located in the western portion of Box-Death Hollow Wilderness Area, Garfield County, southern Utah.

Quantifying plant diversity in Zion National Park, Utah

The vegetation of Zion National Park (ZNP) is used to illustrate the use of various indices that describe aspects of botanical diversity. The simplest method reports the average number of vascular species per 0.01 ha (0.025 acre) macroplot. The MacArthur-Wilson index of diversity is given for each plant community of occurrence in the Park.
