For this approach, depth-to-water measurements from 53 monitoring wells, represented as point values, were differenced between 2006 and 2020. Point values of change were interpolated into a raster to calculate valley-wide groundwater-level change. Groundwater-level change was estimated using two methods (approach 1 and 2) to address groundwater-level measurement uncertainty and constrain groundwater-level change estimates.

Early Estimates of Exotic Annual Grass (EAG) in the Sagebrush Biome, USA, 2022 (ver 3.0, May 18th, 2022) These datasets provide early estimates of 2022 fractional cover for exotic annual grass (EAG) species and one native perennial grass species on a bi-weekly basis from May to early July. The EAG estimates are developed within one week of the latest satellite observation used for that version. Each bi-weekly release contains four fractional cover maps along with their corresponding confidence maps for: 1) a group of 16 species of EAGs, 2) cheatgrass (Bromus tectorum); 3) medusahead (Taeniatherum caput-medusae); and 4) Sandberg bluegrass (Poa secunda).

The distribution and abundance of these EAG species are highly influenced by weather variables such as temperature and precipitation. We set out to develop a machine learning modelling approach using a lightGBM algorithm to predict how changes in annual and immediate past precipitation regimes impact the abundance of EAG in the study area. The predictive model primarily utilized edaphic and weather variables and a seed source proxy from previous years to...

We derived ecological zones by reclassifying LANDFIRE vegetation biophysical setting types, plus defined various non-wildland (e.g. developed urban/agriculture/roads) and non-burnable (e.g. open water/barren) areas using LANDFIRE existing vegetation types. The 43 biophysical setting types present within the study area were grouped into 13 general vegetation types, which were further grouped into 4 elevation-based ecological zones plus one riparian zone according to their constituent plant associations.

Nest site selection was modeled using a generalized linear mixed model of used and random locations in a Bayesian modeling environment, and the midpoint of coefficient conditional posterior distributions were used for prediction. Continuous values were reclassified and ranked using a percent isopleth approach with respect to observed nest locations.
