Learning From the Past and Planning for the Future: Experience-Driven Insight Into Managing for Ecosystem Transformations Induced by Drought and Wildfire Drought and wildfire pose enormous threats to the integrity of natural resources that land managers are charged with protecting. Recent observations and modeling forecasts indicate that these stressors will likely produce catastrophic ecosystem transformations, or abrupt changes in the condition of plants, wildlife, and their habitats, in regions across the country in coming decades. In this project, researchers will bring together land managers who have experienced various degrees of ecosystem transformation (from not yet experiencing any changes to seeing large changes across the lands they manage) to share their perspectives on how to mitigate large-scale changes in land condition. The team will conduct surveys... Categories: Project; Types: Map Service, OGC WFS Layer, OGC WMS Layer, OGC WMS Service; Tags: 2020, CASC, Drought, Drought, Drought, All tags...

This data will then be combined with ecosystem water balance model simulations to establish features of water availability critical for plant species response. Results will allow managers to identify species and communities at risk under future climate scenarios based on predicted changes in plant water availability. Due to the high variability in soils, incorporating a detailed understanding of soil water availability beyond bioclimatic envelope approaches in the desert Southwest is essential...

The objectives of the study were to 1) assess the effect of oil and gas development on surface roughness, and 2) model the resultant effect of oil and gas development on sediment mass flux for a range of 10-m wind speeds and threshold wind friction velocities. These data represent monthly means of normalized scaled surface wind friction velocity - a metric modelled from land surface albedo that approximates surface roughness - of March to October of the years 2001 to 2016. These data are representative of disturbed and undisturbed sites located in five climate-soil strata...

In this region, grassland dynamics are tightly linked to available moisture, yet it has proven difficult to resolve what aspects of climate drive vegetation change. In part, this is because it is unclear how heterogeneity in soils affects plant responses to climate. Here, we combine climate and soil properties with a mechanistic soil water model to explain temporal fluctuations in perennial grass cover, quantify where and the degree to which incorporating soil water dynamics enhances our ability to understand temporal patterns, and explore the potential consequences...

This vegetation change has been perceived to have a significant impact on the economic value of these grasslands, which support activities such as livestock grazing and hunting, but expanding pinyon and juniper forests may also lead to increased risk of fire. Over the past several decades pinyon-juniper forests have been removed across large areas of land to improve wildlife habitat and grazing land productivity while reducing risks of wildland fire. What isn’t known is whether these strategies are effective in reaching this goal, especially given that our future climate will likely be hotter and drier...
