Examination of Surveys to Measure Renewable Energy Effects on Birds and Bats

Although renewable energy facilities are often required to complete wildlife surveys before and after constructing facilities, there is a lack of published studies that have closely examined the types of surveys and whether they are comparable within and across facilities.

Response of Biocrust to Fuel Reduction Treatments

In the sagebrush steppe, land managers use fuel reduction treatments to minimize large fire risk. Although biocrusts are associated with reduced cover of fire-promoting, invasive grasses, the impact of fuel reduction treatments on biocrusts is poorly understood.

Frequent Fire Reduces Deep Soil Carbon

Fire activity is changing worldwide, with unclear effects on ecosystem carbon storage. Fire effects on carbon storage are better known for vegetation than for soil, and fire effects on deep soil carbon are especially uncertain.

Excluding Grazing has Positive Effects on Riparian Vegetation, Migratory Birds

Livestock grazing can degrade riparian vegetation, altering habitat for many species of declining migratory breeding birds. At Hart Mountain National Antelope Refuge in southeastern Oregon, cattle were removed from riparian areas in 1990 after 120 years of grazing.

Weed-Suppressive Bacteria Did Not Control Bromus tectorum

Recent trials using a bacterial bioherbicide known as D7 have had mixed results in controlling invasive annual grasses in rangelands.

Components and Predictors of Biocrusts

Although biological soil crusts occur globally in arid and semi-arid environments, the occurrence of biocrusts has not previously been related to individual plant communities at regional scales.

Estimating Population Size with Imperfect Detection Using a Parametric Bootstrap

Methods exist for estimating the size of a population of imperfectly detected individuals, yet problems arise when the detection probability and the observed count of individuals are both small.
