UNL scientists are part of a coalition helping two American Indian tribes prepare for drought and other climate fluctuations. The tribes — the Eastern Shoshone and Northern Arapaho, both located on the Wind River Indian Reservation in western Wyoming — have worked with climate and social scientists in the past year to prepare regular climate and drought summaries for use in making water and resource decisions. A second phase, launched this summer, includes UNL's Cody Knutson and will generate a vulnerability assessment designed to help the tribes reduce the likelihood of future drought-related impacts.

This project conducts an interdisciplinary, technical assessment of key social-ecological vulnerabilities, risks, and response capacities of the Wind River Indian Reservation (WRIR) to inform development of decision tools to support drought preparedness. It also provides opportunities for 1) development of tribal technical capacity for drought preparedness, and 2) educational programming guided by tribal needs, Traditional Ecological Knowledge (TEK), and indigenous observations of drought for tribal members, with a longer-term goal of transferring lessons learned to other tribes and non-tribal entities. This project has foundational partnerships between the Eastern Shoshone and Northern Arapaho tribes of the WRIR,...
Water laws and drought plans are used to prioritize and allocate scarce water resources. Both have historically been human-centric, failing to account for non-human water needs. In this paper, we examine the development of instream flow legislation and the evolution of drought planning to highlight the growing concern for the non-human impacts of water scarcity. Utilizing a new framework for ecological drought, we analyzed five watershed-scale drought plans in southwestern Montana, USA to understand if, and how, the ecological impacts of drought are currently being assessed. We found that while these plans do account for some ecological impacts, it is primarily through the narrow lens of impacts to fish as measured...

The production of dairy and beef is important for food security and the economies of the U.S. Caribbean. The dairy industry is the leading agricultural sector in Puerto Rico, contributing about 22% of the total agricultural income. Region-wide, beef and dairy production generate over 25,000 jobs and occupy more than 50,000 acres. In the U.S. Virgin Islands, cattle production has been declining in recent years due to higher insurance costs and natural disasters, while sheep and goat production has increased. Caribbean countries are particularly vulnerable to climate change due to their geography and economic capacity. Climate change is driving temperatures higher and the region is experiencing more frequent and intense...

Landscape capability (LC) models are a spatial tool with potential applications in conservation planning. We used survey data to validate LC models as predictors of occurrence and abundance at broad and fine scales for American woodcock (Scolopax minor) and ruffed grouse (Bonasa umbellus). Landscape capability models were reliable predictors of occurrence but were less indicative of relative abundance at route (11.5–14.6 km) and point scales (0.5–1 km). As predictors of occurrence, LC models had high sensitivity (0.71–0.93) and were accurate (0.71–0.88) and precise (0.88 and 0.92 for woodcock and grouse, respectively). Models did not predict point-scale abundance independent of the ability to predict occurrence...

In the western U.S., rising temperatures and pronounced drought conditions pose significant challenges to public land managers. Widespread declines of multiple plant species have already been observed, providing insight into what the future could look like for vegetation in the region as conditions are projected to become warmer and drier. To understand how vulnerable western ecosystems are to drought, managers need to know which climatic and soil conditions cause habitats to change, and at what rate these changes may occur – important topics on which there is little available data. This project seeks to identify the vulnerability of habitats in the western U.S. to drought. Researchers will compare changes in...

Extreme events not only affect people but can have detrimental impacts on natural resources, such as fish and freshwater habitats. Impacts of extreme events, like hurricanes, tornadoes, and extreme flooding, have immediate consequences, but also have the ability to alter habitats and animals far in the future by providing opportunities for exotic species to colonize new areas. Some fish communities in streams, rivers, and lakes may have the natural ability to resist the long-term impacts of extreme weather events. In this project, researchers will investigate the ability of Caribbean fish assemblages in Puerto Rico, which have both economic and cultural importance, to resist the impacts of extreme weather events....

The scaled quail is an important species that indicates the overall health of the habitats they occupy in the arid Southwest. Some populations are declining, which may be linked to the long-term trend in warmer, drier conditions and reduced monsoonal rainfall across their range. It’s believed that temperature and humidity levels have been too high, reducing the survival of eggs and chicks. Climate models project decreasing rainfall and warming temperatures to continue for the region, so understanding this linkage is becoming increasingly critical. To address this need, researchers sought to measure the success of scaled quail nests at locations across their range, to determine if nest success is related to temperature,...

A growing number of wildfire-burned areas throughout the western United States are expected to increase soil erosion rates within watersheds, causing more sediment to be present in downstream rivers and reservoirs, according to a new study by the U.S. Geological Survey.
This dataset includes the cover of creosote bush (Larrea tridentata)in 1989, 1995, 1999, 2005, and 2009 across southern Arizona. Cover was determined using sub-pixel classifications of two Landsat scenes from path 36, row 38 (centered on latitude: 31.7470, longitude: -111.3981) and path 37, row 38 (31.7470, -112.9431) that encompass Tucson, AZ.

This folder and its contents include summaries produced from fish and habitat surveys conducted in Mason Creek, tributary of the East Fork Lewis River, SW Washington, during summer of 2017. First, estimates of abundance and survival for juvenile coho salmon were generated for three time periods (early, middle, and late) during the summer of 2017 and reported in the file "Estimates of juvenile coho summer abundance and survival_MasonCreek_2017.xlsx". Second, summaries of the continuous habitat surveys can be found in the file "FinalStats_MasonMill2017_FishRescue.xlsx". Specifically here, the total length of stream habitat by habitat type (flowing, fragmented, dry) and the frequency and area of stream pools are summarized...
The datasets in these child pages are continuous parameter grids (CPG) of annual air temperature data for the years 2000 through 2016 in the Pacific Northwest. Source temperature data was produced by the PRISM Climate Group at Oregon State University.
