Restoration ecology in conflict along the Colorado front range
Restoration Ecology, EarlyView.Abstract Introduction Cheatgrass (Bromus tectorum) is a challenge to restoration in western North America. It attracts the attention of academic and government research scientists, weed managers, and chemical companies. Attempts to control it cause conflicts among these groups.

Restoration Ecology, EarlyView.Abstract Introduction The invasion of the winter annual grass Cheatgrass (Bromus tectorum L.) reduces native plant biodiversity and increases wildfire risk in western North America. Seed‐based restoration often fails to increase native plant recruitment in degraded, Cheatgrass‐invaded areas.

Restoration Ecology, EarlyView.Abstract Introduction Biocrusts are increasingly recognized for their contribution to soil stability, hydrology, nutrient cycling, and energy balance in drylands, yet practical field methods for assessing functional roles are limited. Existing approaches typically rely on cover estimates, taxonomic identification, or laboratory analyses, providing ...

Eco-hydrological impacts and socio-economic drivers of rangeland degradation due to overgrazing in semi-arid and arid regions: a review [PDF]
Mesopotamia Journal of AgricultureGlobal rangelands have experienced severe degradation over the past three centuries due to anthropogenic and climatic pressures. Rapid population growth, urbanization, and socioeconomic transformations have driven widespread overgrazing, threatening both

Restoration Ecology, EarlyView.Abstract Introduction Roadside vegetation management efforts often target a single desirable outcome; however, we frequently have multiple management goals for restoration. Multiple goals may be achieved concurrently, but the efficacy of roadside revegetation methods is largely unclear, especially when multiple methods are combined.

Grazing intensity on the plant diversity of alpine meadow in the eastern Tibetan plateau
Rangifer, 2004 Because ofthe remoteness and harsh conditions of the high-altitude rangelands on the eastern Tibetan Plateau, the relationship between yak grazing and plant diversity has not been so clear although livestock increase was thought as the main issue leading
