Understanding How Changes In Precipitation Intensity Will Affect Vegetation In The Western U.S., Cristina Chirvasa
Understanding How Changes In Precipitation Intensity Will Affect Vegetation In The Western U.S., Cristina Chirvasa
Fall Student Research Symposium 2021
Precipitation events are becoming more intense as the atmosphere warms, but it remains unclear how precipitation intensification will affect plant growth in arid and semiarid ecosystems. There is conflicting evidence suggesting that larger precipitation events may either increase or decrease plant growth. Here, we report the growth responses of herbaceous and woody plants to experimental manipulations of precipitation intensity in a cold, semi-arid ecosystem in Utah, USA. In this experiment, precipitation was collected and redeposited as fewer, larger events with total annual precipitation kept constant across treatments. Results from the first two growing seasons revealed that more intense events ‘pushed’ …

Maintaining healthy rangeland ecosystems requires adaptive co-management at the landscape scale. Because the majority of western rangelands are publicly owned, it is critical that federal land management agencies work together in generating and sharing information. Promotion and communication of rangeland management innovations among agencies is one means of sharing information. Two rangeland management innovations, the Weather-Centric Restoration Tool and Interpreting Indicators of Rangeland Health, were studied in order to better understand agency adoption decisions and barriers to diffusion of the innovations across agencies. Using a mixed qualitative methodology, we interviewed land managers across the floristic Great Basin and in southeastern …

Human–Wildlife Interactions
The U.S. Pacific coast population of the western snowy plover (Charadrius nivosus nivosus; plover) has declined due to loss and degradation of coastal habitats, predation, and anthropogenic disturbance. The U.S. Fish and Wildlife Service listed the subspecies in 1993 as threatened under the Endangered Species Act due to the population declines and habitat loss. Predation of nests and chicks has been identified as an important cause of historic population declines, and thus, most predator management actions for this subspecies are focused on reducing this pressure. In recent years, common ravens (Corvus corax; ravens) have become the most …
