Mapping When and Where Invasive Buffelgrass is Green: Buffelgrass is an invasive perennial grass that threatens Sonoran desert ecosystems in the southwestern USA by out-competing native plants and altering fire regimes. Fires fueled by buffelgrass can ultimately transform the Sonoran Desert ecosystem from a diverse assemblage of plants that supports a rich diversity of fauna to a desert grassland monoculture that burns regularly, threatening lives and property. USGS scientists, Cynthia Wallace, Jessica Walker and Jake Weltzin, conducted research with colleagues to map the presence and phenological status of the invasive by integrating ground observations of buffelgrass phenology collected by citizen scientists and professionals, a map of buffelgrass distribution in Saguaro National Park (SNP), climate information, and Moderate-resolution Imaging Spectroradiometer (MODIS) imagery. Knowing WHERE buffelgrass is located and WHEN it is green enables the strategic application of herbicide, which is only effective when the plants are photosynthetically active and are at least 50% green. The results expose buffelgrass due to its more rapid response to precipitation events than native vegetation (i.e., areas with buffelgrass display strong correlations between MODIS greenness and lagged precipitation), and reveal that precipitation data can predict green-up, whereas MODIS data can confirm green-up. The research was conducted to assist buffelgrass control activities of the National Park Service at SNP and was supported by USGS funds from CLU, WGSC and NPMP, as well as the USA National Phenology Network. The results, which can be used to identify and treat buffelgrass during optimal time periods, are published in the peer reviewed journal article, “Mapping Presence and Predicting Phenological Status of Invasive Buffelgrass in Southern Arizona Using MODIS, Climate and Citizen Science Observation Data” in Remote Sensing, 2016, 8(7), 524; doi:10.3390/rs8070524.

New publication on remote sensing of drought and fire effects on desert grasslands: Western Geographic Science Center researchers published a study in Remote Sensing of Environment that describes new methods for monitoring changes in grassland condition after fire and drought using a 27-year Landsat time series and field monitoring data. The aim of the study was to provide information to guide habitat restoration in the southwestern United States, where land managers are using prescribed fire as a tool to combat encroachment of woody plants and non-native grasses. Image processing techniques were used to identify post-fire shifts in native, non-native, and annual plant cover, and statistically significant differences in plant cover were found between unburned reference areas and burned areas, especially when fires occurred during drought. This research was done in collaboration with the National Park Service’s Southwest Exotic Plant Management Team, the University of Arizona, and the US Fish and Wildlife Service.

USGS scientist to present research on California’s projected land use related water demand: On Monday, May 23, Research Geographer Tamara Wilson will present her work modeling potential future land use in California and the associated water demand at the Society for Freshwater Science meeting in Sacramento, CA. Using the Land Use and Carbon Scenario Simulator (LUCAS) model, her team projected spatially explicit (1 km) future changes in urbanization, agricultural expansion and contraction, and agricultural change from 2012 to 2062 and estimated the associated water use for California’s Central Valley and Oak Woodlands ecoregions. Under current water use efficiency rates, total water demand was projected to increase 4.1% (1.4 million acre feet) by 2062, driven primarily by increases in urbanization and shifts to more water intensive perennial cropland (i.e. orchards and vineyards). Growing demand for water may present a challenge as the state’s future supplies are in question, given current water use demand, the ongoing current drought, and projected future climate warming. Contact: Tamara Wilson email@example.com

High resolution remote sensing to map and monitor biological soil crusts in southeastern Utah: Western Geographic Science Center (WGSC) researchers are leading an effort to map and monitor biological soil crusts (biocrusts) using Unmanned Aerial Vehicles (UAVs) and high-resolution multispectral satellite imagery. Biocrusts (communities of mosses, lichens, cyanobacteria) are important for nutrient cycling and stabilizing desert soils but their condition and extent are difficult to determine in remote and rugged areas like Utah’s Canyonlands. During the week of May 8, the team will use UAVs to collect high-resolution (<1 cm) near-infrared and color images over a number of biocrust monitoring plots established by USGS in 2006. Worldview-3 satellite data (31 cm panchromatic resolution, 1.24 m Multispectral, and 3.7 m Short-Wave Infrared) covering Canyonlands National Park and adjacent BLM management units will be acquired at the same time. Hand-held field spectroradiometer measurements will be collected to characterize spectral reflectance profiles of biocrusts, soils, and vegetation, which along with field cover and UAV data will be used to scale-up biocrust information over the larger landscape. This work is a collaborative effort between researchers from WGSC, Southwest Biological Science Center, Canyonlands Research Center (http://canyonlandsresearchcenter.org/) and University of Colorado. For more information contact Miguel Villarreal (firstname.lastname@example.org) or John Vogel (email@example.com).
Future land-use related water demand in California: The USGS will be publishing an article in the forthcoming Environmental Research Letters presenting new state-and-transition simulation modeling results of projected land use and land cover change in California and associated shifts in water-use demand. The study shows anthropogenic land use increasing over 8% or by nearly 4,500 km2 by the year 2062, mostly at the expense of rangelands, while total cropland area declined 8.6%. The modeled continuation of current trends in developed (municipal and industrial) land use along with continued shifts from annual to perennial cropland could lead to a 4.6% (~ 1.6 million acre feet) increase in water demand over current use estimates by 2062. This a cause for concern, given projections of future climate warming, declining snowpack, and increasing drought frequency, duration, and intensity, which already threaten the state’s limited, over-allocated, and highly variable inter-annual water supplies. Results indicate that only if currently mandated 25% reductions in municipal water use are continuously implemented would water demand in 2062 balance to water use levels in 2012. This is the first modeling effort of its kind to examine regional land-use related water demand incorporating historical trends in both developed and agricultural land uses. Publication date is unknown at this time.
Continuous 1985–2012 Landsat Monitoring to Assess Fire Effects on Meadows in Yosemite National Park, California: Researchers from the USGS Western Geographic Science Center and UC Davis have recently published an open access article in the journal Remote Sensing (MDPI) describing the use of Google Earth Engine cloud computing to assess how montane meadow vegetation recovered after a wildfire that occurred in Yosemite National Park, CA in 1996. This application, which was funded by the Southwest Climate Science Center (SWCSC), illustrates how Google Earth Engine may be employed to conduct near-continuous vegetation monitoring with Landsat TM imagery, ultimately allowing the long-term effects of disturbances to be studied more effectively. The article can be found at http://www.mdpi.com/2072-4292/8/5/371/html (Christopher Soulard, firstname.lastname@example.org, 650-329-4317).

California’s land-use related water demand projected to grow: On December 14th, USGS geographer Tamara Wilson will be presenting new state-and-transition simulation modeling results of projected land use and land cover change in California and associated shifts in water-use demand at the upcoming AGU meeting in San Francisco. Model findings show water use increasing 4.6% over current use estimates by the year 2062, representing a continuation of current trends in developed (municipal and industrial) land consumption along with continued shifts from annual to perennial cropland. As a result, future land-use related water demand in California may exceed current use levels if historical trends in land use persist. This is cause for great concern given projections of future climate warming, declining snowpack, and increasing drought frequency, duration, and intensity, which could threaten the state’s already limited, overly allocated, and highly variable water supplies.

Mapping belowground biomass in restored Delta wetlands: USGS and U.C. Berkeley scientists have developed methods to model and map plant belowground biomass and root:shoot ratios in restored wetlands managed to reverse land subsidence and increase carbon sequestration in the Sacramento-San Joaquin River Delta, California. The peat soils of the Delta represent a significant carbon pool, and the roots and rhizomes of wetland vegetation are the primary source of organic carbon for peat formation. However tracking belowground productivity in the field is time consuming, expensive and difficult. A recent study, published in Remote Sensing, describes a hybrid modeling approach for quantifying relative differences in belowground biomass and root:shoot ratios that applies estimates of leaf nitrogen concentration and plant aboveground biomass derived from Landsat satellite data. These methods can be applied over large scales to monitor the success of restored wetlands, assess wetland resilience to sea level rise, and quantify Blue Carbon, the carbon stored in coastal vegetated ecosystems.

USGS scientists examine future land use related water demand in California: Water shortages in California are a growing concern amidst ongoing drought, earlier spring snowmelt, projected future climate warming, and currently mandated water use restrictions. As population and associated land consumption increase in coming decades, already limited water supplies will face additional pressure to meet growing demand. We used a state-and-transition simulation model to project future changes in developed (municipal and industrial) and agricultural land use to estimate associated water use demand by the year 2062. Overall, water use demand was projected to increase 4.6% or by 1.6 million acre feet. Developed land uses increased nearly 55% and contributed to the 5.5% decline in agriculture-related water demand by 2062. The results of this work were presented at the Southwest Climate Science Summit meeting on November 2 in Sacramento, CA. For more information, contact Tamara S. Wilson, Western Geographic Science Center, Menlo Park, CA 94025, USA email@example.com

Conservation planning for offsetting renewable energy impacts in the Mojave Desert: A paper authored by WGSC scientist Jason Kreitler presents a new decision support tool for offsetting impacts of solar energy on biodiversity in the Mojave Desert. Balancing society’s competing needs of development and conservation requires careful consideration of tradeoffs. While renewable energy and biodiversity conservation are often considered beneficial environmental goals, the direct footprint and disturbance of renewable energy development can displace species’ habitat and negatively impact populations and natural communities. To address this need the authors designed an offset siting support tool for the Desert Renewable Energy Conservation Plan (DRECP) of California, and present a case study of offsetting a set of hypothetical impacts from proposed solar energy development sites.
