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). These datasets were generated leveraging field observations from Bureau of Land Management (BLM) Assessment, Inventory,...

As the origin of three major basins that drain the Columbia, Missouri, and Saskatchewan rivers, Montana is the hydrologic apex for North America. The Northern Rocky Mountain region is home to some of the last remaining interconnected habitats for many native fishes, including the threatened bull trout and native westslope cutthroat trout. The Northern Rockies are also experiencing rapidly changing climate conditions, with temperatures rising at twice the global average. These changes are having a range of impacts on aquatic ecosystems, including warming stream temperatures and changing streamflow regimes. This region is also experiencing a rise in the expansion of alien invasive fish species, which further threaten...

There is growing interest in the facilitated movement of plants as a means of conserving or restoring species and habitats, as climate conditions and management goals change. For example, plants might be relocated to support pollinator conservation or the restoration of prairies. Some land managers, in an effort to be proactive in the face of changing environmental conditions, are also considering relocating plants to sites that are considered more similar to anticipated future conditions. However, moving plants can be ecologically and economically risky. It’s possible that pests, pathogens, or contaminant weeds can be inadvertently moved along with the target plant material. In 2016, the noxious weed Palmer amaranth...
