Early Estimates of Exotic Annual Grass (EAG) in the Sagebrush Biome, USA, 2024 These datasets provide early estimates of 2024 fractional cover for exotic annual grass (EAG) species and one native perennial grass species on a weekly basis from April to late June. Typically, the EAG estimates are publicly released within 7-13 days of the latest satellite observation used for that version. Each weekly release contains five fractional cover maps along with their corresponding confidence maps for: 1) a group of 16 species of EAGs, 2) cheatgrass (Bromus tectorum); 3) Field Brome (Bromus arvensis); 4) medusahead (Taeniatherum caput-medusae); and 5) Sandberg bluegrass (Poa secunda).

A Geographic Information System (GIS) was developed to derive model input data from Light Detection and Ranging (lidar) Digital Elevation Models (DEM) at each stream crossing location. Hydraulic models were built for existing culvert designs as well as preliminary culvert designs for a 3-sided box, 3-sided arch, and a pipe culvert using field survey and GIS data.

Between May and September of that year, 24 fissures opened on the lower flank of the volcano, producing lava fountains and expansive lava flows that covered an area of 36 km2 (Neal and others, 2019; Zoeller and others, 2020). Effusion rates at the dominant vent, fissure 8, were often >100 m3 s-1, and the total eruptive volume is estimated at 0.9–1.4 km3 (Dietterich and others, 2021) making it one of the most voluminous effusive...
