Grassland compost amendments increase plant production without changing plant communities

Ecosphere, 2016
Compost amendment to grassland is a novel strategy proposed and demonstrated to increase ecosystem carbon (C) storage. However, the effects of compost applications on biomass production and plant diversity are not well known. We assessed impacts of a one‐

Extracting exotic annual grass phenology and climate relations in western U.S. rangeland ecoregions

Biological Invasions, 2023
AbstractThis research builds upon the extensive body of work to model exotic annual grass (EAG) characteristics and invasion. EAGs increase wildland fire risk and intensifies wildland fire behavior in western U.S. rangelands. Therefore, understanding characteristics of EAG growth increases understanding of its dynamics and can inform rangeland ...

Intra‐site sources of restoration variability in severely invaded rangeland: Strong temporal effects of herbicide–weather interactions; weak spatial effects of plant community patch type and litter

Ecological Solutions and Evidence, 2022
Invasions by exotic annual grasses (EAGs) are replacing native perennials in semiarid areas globally, including the vast sagebrush‐steppe rangelands of western North America.

Soil Seed Banks of the Exotic Annual Grass Bromus rubens on a Burned Desert Landscape [PDF]

Rangeland Ecology & Management, 2013
Red brome (Bromus rubens), an exotic annual grass, can dominate soil seed banks and poses serious threats to mature native plant communities in the Mojave Desert by competing with native species and providing fine fuels that facilitate widespread wildfire.

To burn or not to burn: Comparing reintroducing fire with cutting an encroaching conifer for conservation of an imperiled shrub‐steppe

Ecology and Evolution, 2019
Woody vegetation has increased on rangelands worldwide for the past 100–200 years, often because of reduced fire frequency. However, there is a general aversion to reintroducing fire, and therefore, fire surrogates are often used in its place to reverse ...

Influence of landscape-scale variables on vegetation conversion to exotic annual grassland in southern California, USA

Global Ecology and Conservation, 2014
In California, USA, coastal sage scrub (CSS) vegetation is being converted to exotic annual grassland, and several causes have been suggested. In order to investigate the importance of environmental variables in the conversion and recovery of CSS ...

Ungulate herbivores as drivers of aspen recruitment and understory composition throughout arid montane landscapes

Ecosphere, 2022
Herbivory by wild and domestic ungulates can influence tree recruitment and understory forest communities throughout the world. Herbivore‐driven declines in tree recruitment have been observed for quaking aspen (Populus tremuloides), a foundation species

Are Early Summer Wildfires an Opportunity to Revegetate Exotic Annual Grass–Invaded Plant Communities? [PDF]

Rangeland Ecology & Management, 2013
Medusahead (Taeniatherum caput-medusae [L.] Nevski) is an exotic annual grass invading western rangelands. Successful revegetation of invaded-plant communities can be prohibitively expensive because it often requires iterative applications of integrated control and revegetation treatments.

A Common-Garden Study of Resource-Island Effects on a Native and an Exotic, Annual Grass After Fire [PDF]

Rangeland Ecology & Management, 2012
Plant-soil variation related to perennial-plant resource islands (coppices) interspersed with relatively bare interspaces is a major source of heterogeneity in desert rangelands. Our objective was to determine how native and exotic grasses vary on coppice mounds and interspaces (microsites) in unburned and burned sites and underlying factors that ...

Community‐based long‐term management to address reinvasion of restored grassland vernal wetlands

Ecosphere
Exotic annual grasses can dominate ecosystems by producing a thick layer of dead plant litter, hereafter “thatch,” which promotes the regeneration of exotic grasses and inhibits native plants. Vernal pool wetlands within a grassland matrix are threatened
