These data represent habitat selection of greater sage-grouse at the 50 day mark of their brood rearing process. Sage-grouse and their broods were monitored on their own individual time lines, so one group's 50th day may not necessarily be the same as any other bird's 50th day.
The Gulf Coast Vulnerability Assessment (GCVA) used an expert opinion approach to qualitatively assess the vulnerability of four ecosystems: mangrove, oyster reef, tidal emergent marsh, and barrier islands, and a suite of wildlife species that depend on them. More than 50 individuals participated in the completion of the GCVA, facilitated via Ecosystem and Species Expert Teams. The GCVA made use of the Standardized Index of Vulnerability and Value Assessment (SIVVA) (Reece and Noss 2014) to provide an objective framework for evaluating vulnerability by guiding assessors through a series of questions related to the changes an ecosystem or species might experience due to climate change and other threats. Assessors...

Despite the proven efficacy of geothermal energy as a city-scale heating and cooling resource, the relative newness of most city-scale applications using diverse technologies has resulted in limited widespread adoption. We aim to develop authoritative information suitable for city-managers and other decision-makers. Geothermal resources are ubiquitous and diverse, with technologies available both for harvesting ambient heat or for storing thermal energy. These local low-carbon, baseload energy sources provide resilience, security, and jobs. The project team proposes to accelerate understanding and possibly energy-solution adoption by developing an international systematic nomenclature to describe the range of...

This is the collection of raw data was collected during MBM-AK TLSA annual molting goose surveys. Partial quality control has been completed for these data: following each survey, the observer listened to their survey recording that documented counts along transects and then transcribed these findings into these raw datasets (‘raw_data’). The observer listened to their recording a second time in order to confirm that their transcriptions were correct. Further quality control and tidying was completed for these raw data using R scripts noted by the file extension ‘.Rmd’ located in the ‘GitHub_Annual_Report_Code’ folder. Ultimately, these scripts produced final datasets (‘final_data’) containing data used in annual...

These are the observer names, observer initials, year, and unique observer number for all observe that collected data on the YKD nest plot project from 1985 to 2019. This data is used with the nest card data to in various ways, but primarily to calculate cumulative observer experience for nest detection rates. This file is also used for quality control and reconciling non-unique observer initials across years.

From 1995 to 1999, a subset of nest plots were searched twice by field crews to estimate nest detection probability by mark-recapture methods. Over the five years, 30 plots were searched twice and over 2700 unique nests were found. From these data, nest detection probability is estimated using a Huggins-type mark recapture model where individual-level covariate effects of nest and observer attributes were estimated. These estimates are then used to predict nest detection rates in other years based on covariates of nests and observers. Nest detection rates are then applied to annual plot search to estimate nest populations for each species in the sampled area.

R code that takes in the nest capture history data (chdata.csv), reformats it for model fitting in Program Mark via the R package RMark. A series of models of increasing complexity are fit and compared using AIC. Output is written to text files for each model but is generally not used or saved. Code can be run to generate model results and R workspaces/ object to inspect parameter estimates. The primary purpose of this code is to explore model structures for predicting detection and as an attempt to reproduce historically used parameter estimates in past nest plot reports (e.g., Fischer et al. 2017 and earlier). Results from ‘Model 7’ are most similar to detection estimates used in the past.

This geopackage contains the density strata that were used to create the Alaska Arctic Coastal Plain Aerial Breeding Pair Survey four-year rotating panel design. This file was derived from a mid-1980’s ArcInfo coverage for the North Slope Eider Survey that was produced through the visual interpretation of 1:250,000-scale LANDSAT imagery and the known nesting density waterfowl in the area.

This dataset contains a raster representing current (2017-2020) core sagebrush, growth opportunity areas, and other rangelands on tribal and federal lands that are estimated to be climate resilient into the future (2030-2060). We determined climate-resiliency by comparing current (2017-2020) core sagebrush, growth opportunity areas, and other rangelands to estimated future (2030-2060) conditions of core and growth opportunity areas under mid-century climate change (Representative Concentration Pathway 8.5) conditions (Doherty et al. 2022). The Department of the Interior (DOI) Sagebrush Keystone Initiative (KI) team worked with partners to identify areas within the sagebrush biome for strategic investments in conservation...

Carbon storage by ecosystem type and protection status was derived from total ecosystem carbon estimates provided by Sleeter et al. 2018 and used to estimate terrestrial carbon storage in developed, forested, shrub/scrub, grassland/herbaceous, and agricultural land in the Southeast United States. It does not include estimates for wetland carbon storage. Sleeter, B.M., Liu, J., Daniel, C., Rayfield, B., Sherba, J., Hawbaker, T.J., Zhu, Z., Selmants, P.C. and Loveland, T.R., 2018.

The Gulf Coastal Plains and Ozarks (GCPO) region is, to a large extent, defined by its mainstem big rivers, with eight of the largest ten rivers (by discharge) in the lower U.S. terminating here. Those rivers are the Mississippi, Ohio, Missouri, Tennessee, Mobile, Atchafalaya, Red, and Arkansas. Whilethis assessment focuses on rivers of the MAV, the analysis has also been extended to big rivers throughout the GCPO.People have historically altered large river systems through the construction of levees and floodways, channelization, and dredging to support agriculture, navigation, commerce, and to provide greater stability and protection from flooding. Many large rivers in the GCPO are, in fact, part of theinland...
Standing dead trees, or snags, are an important habitat element in any forested system, and provide diurnal or seasonal shelter for many LCC priority species. The ISA landscape endpoint for snag density in upland hardwood woodland and forest systems targets one large (≥16” dbh) snag for every five acres of forest (or approximately ~0.2 large snags/acre), reflected by cavity-roosting habitat needs of the silver-haired bat (Lasionycteris noctivagans) and ample other avian, and mammalian species that require cavities in snags to carry out their life history. We used USFS imputed density of large (>16” dbh) snags data (USDA Forest Service Remote Sensing Applications Center, personal communication) extracted through...

Broad Ecosystem Inventory Classification provides broad regional information about the distribution of ecosystems throughout the province and the value of these ecosystemsto wildlife. This is done in order to facilitate the use of wildlife information in broad regional land and resource planning initiatives.Broad Ecosystem Units are mapped based on imagery of the provincialland base generally captured at a scale of 1:250,000.
EAU BC is a hierarchical classification of BC's freshwater ecosystems. It is a spatially explicit classification designed to aid in the management and conservation of BC freshwater ecosystems and their associated biodiversity. EAU BC quantifies the interplay between freshwater species distribution and their ecosystem physical habitat, and environmental processes. It defines what is currently known about freshwater ecosystems and their abundance and distribution across the Province. It is packaged as a database and accompanying geographic information system (GIS) that enables the classification and its underlying data to be queried and viewed at multiple spatial scales. Available EAUBC GIS data include EAUBC Freshwater...
Cropland conversion is anticipated to continue westward from the Great Plains into the sagebrush (Artemisia spp.) biome – the most intact biome remaining in the conterminous United States. However, relatively little is known about the extent and risk of cropland conversion to sagebrush ecosystems and the landscape scale benefits of easements in averting loss of ecological function. Therefore, our goals were to 1) quantify the cropland area of the sagebrush biome, 2) identify where the highest quality sagebrush rangelands are most at risk to future cropland conversion, and 3) estimate the ecological benefits of conservation easements to adjacent public lands. We found that croplands span 14.4 million ha in the sagebrush...
