“…The study uses 2015-18 survey observations to obtain survey and composited estimates of 13 land-health indicators of sagebrush communities in Wyoming Core and NonCore Greater Sage-Grouse (Centrocercus urophasianus) conservation areas [24][25][26] on BLM-managed lands. The Greater Sage-Grouse (hereafter sage-grouse) is a species of conservation concern in the western U.S. [27]. State-wide Core designations bound areas with large sage-grouse population sizes and have stringent stipulations limiting energy development and overall disturbance of sage-grouse populations and habitat [26].…”

Long-term environmental monitoring surveys are designed to achieve a desired precision (measured by variance) of resource conditions based on natural variability information. Over time, increases in resource variability and in data use to address issues focused on small areas with limited sample sizes require bolstering of attainable precision. It is often prohibitive to do this by increasing sampling effort. In cases with spatially overlapping monitoring surveys, composite estimation offers a statistical way to obtain a precision-weighted combination of survey estimates to provide improved population estimates (more accurate) with improved precisions (lower variances). We present a composite estimator for overlapping surveys, a summary of compositing procedures, and a case study to illustrate the procedures and benefits of composite estimation. The study uses the two terrestrial monitoring surveys administered by the Bureau of Land Management (BLM) that entirely overlap. Using 2015–18 data and 13 land-health indicators, we obtained and compared survey and composite indicator estimates of percent area meeting land-health standards for sagebrush communities in Wyoming’s Greater Sage-Grouse (Centrocercus urophasianus) Core and NonCore conservation areas on BLM-managed lands. We statistically assessed differences in indicator estimates between the conservation areas using composite estimates and estimates of the two surveys individually. We found composite variance to be about six to 24 units lower than 37% of the survey variances and composite estimates to differ by about six to 10 percentage points from six survey estimates. The composite improvements resulted in finding 11 indicators to statistically differ (p <0.05) between the conservation areas compared to only six and seven indicators for the individual surveys. Overall, we found composite estimation to be an efficient and useful option for improving environmental monitoring information where two surveys entirely overlap and suggest how this estimation method could be beneficial where environmental surveys partially overlap and in small area applications.

“…Greater sage-grouse (Centrocercus urophasianus) embody this conflict. The wealth of research undertaken to inform a listing decision for the species (US DOI 2015) led BLM to request development of an online, searchable annotated bibliography (https://apps.usgs.gov/scien ce-for-re sou rce-managers) and science synthesis (Hanser et al 2018). Science syntheses in general are highly valued by managers (Seavy and Howell 2010), as are digital products that help managers easily find and access relevant science and aid in the comprehension of its core implications (Davis et al 2013).…”

Public land management agencies in the US are committed to using science‐informed decision making, but there has been little research on the types and topics of science that managers need most to inform their decisions. We used the National Environmental Policy Act to identify four types of science information needed for making decisions relevant to public lands: (1) data on resources of concern, (2) scientific studies relevant to potential effects of proposed actions, (3) methods for quantifying potential effects of proposed actions, and (4) effective mitigation measures. We then used this framework to analyze 70 Environmental Assessments completed by the Bureau of Land Management in Colorado. Commonly proposed actions were oil and gas development, livestock grazing, land transactions, and recreation. Commonly analyzed resources included terrestrial wildlife, protected birds, vegetation, and soils. Focusing research efforts on the intersection of these resources and actions, and on developing and evaluating the effectiveness of mitigation measures to protect these resources, could strengthen the science foundation for public lands decision making.

“…Three studies of how grazing may affect Greater Sage-Grouse populations have been published since 2015 (Carter et al 2018;Hanser et al 2018). In Wyoming, Monroe et al (2017) found grazing effects depended on the timing and level of grazing.…”

The Bureau of Land Management's multiple-use mission is to sustain the health and productivity of the public lands for the use and enjoyment of present and future generations. The Bureau accomplishes this by managing such activities as outdoor recreation, livestock grazing, mineral development, and energy production, and by conserving natural, historical, cultural, and other resources on public lands.Cover Photo:
