DLCC’s Vegetation Map Pilot is a project envisioned initially as a supervised classification of two or three small areas of the DLCC. DLCC technical stakeholders advised changing from a supervised classification to an object oriented classification (OOC) method.This report presents the findings, feasibility, and lessons-learned during the exploration and object oriented classification process and results of the two sites on the United States-Mexico border, this is needed information before considering a full-scale, Vegetation Mapping Project, to include bigger areas or the totality of the Desert LCC region.

We have developed autonomous and high precision sensor arrays to monitor growth of individual native plants along with local environmental conditions, coupled with wireless data loggers that can provide real-time data available to managers and the wider public. We deployed an experimental set of these sensors, integrated with a weather station, 2 webcams, and a live web portal (construction in progress) to showcase how this real time information can be useful to relevant managers while also raising awareness of the challenges of climate change adaptation and Hawaiian plant conservation in general. With the increasing popularity of wildlife web-cams, it has been shown that this type of technology has a strong ability...

This scenario planning decision support tool for the Kankakee River basin as a first case study/proof-of concept. Hydrology models, both surface water and groundwater, and ecology of the Kankakee River watershed will be combined to evaluate the effects of habitat restoration on water suppy ecosystem services, agricultural irrigation demands, urbanization, and waterfowl habitat, and sportsman and recreational user interests. Various scenarios for restoration identified with peer input were tested for the watershed. Each scenario results in different individual and aggregate values for ground water recharge, surface water storage, waterfowl habitat, sportsman and recreational use, and agricultural capacity. Some...

This project will result in development of an information management and delivery system to coordinate science communication platforms and to build a catalog inside of the USGS ScienceBase data and information management platform. The tasks maximize use of available products and services developed and tested by data experts working together through LCC's, Climate Science Centers, and the National Climate Change and Wildlife Science Center. In working with USGS Fort Collins (FORT) to complete the tasks, the Desert LCC will be responsible for providing input on specifications, data entry and maintenance of records in Science Base to populate the tools that comprise the information management and delivery system, and...

Conversion of grassland restored under the Conservation Reserve Program (CRP) back into croplands is occurring at a rapid rate at CRP contracts expire. A fee-market approach may be necessary to incentivize preservation of these restored grassland by assessing value to ecosystems services such as carbon sequestration.

Sediment accumulation threatens the viability and hydrologic functioning of many naturally formed depressional wetlands across the interior regions of North America. These wetlands provide many ecosystem services and vital habitats for diverse plant and animal communities. Climate change may further impact sediment accumulation rates in the context of current land use patterns. We estimated sediment accretion in wetlands within a region renowned for its large populations of breeding waterfowl and migrant shorebirds and examined the relative roles of precipitation and land use context in the sedimentation process. We modeled rates of sediment accumulation from 1971 through 2100 using the Revised Universal Soil Loss...

Estimates of nutrient loading to the Gulf of Mexico indicate that nine states within the Mississippi River Basin are responsible for approximately 75% of all nitrogen and phosphorus delivered to the Gulf. The Mississippi Basin also supports a rich assemblage of fish species; at least 25% of all species in the conterminous United States are found in the Basin. These assemblages reflect their habitats, human landscape disturbances, and fragmentation of the river network by dams. Climate also has close associations with aquatic habitat conditions and ultimately fish community composition. Climate change is anticipated to lead to additional changes in stream habitats, including changing thermal properties and flow regimes....

ABSTRACT: The Lower Colorado River and Rio Grande Basins are home to many riparian vertebrate species with different degrees of rarity. In our study, we focused on two species of birds and two species of gartersnakes that are associated with riparian areas: the Yellow-breasted Chat (Icteria virens), the Yellow Warbler (Setophaga petechia), the Northern Mexican Gartersnake (Thamnophis eques megalops) and the Narrow-headed Gartersnake (T. rufipunctatus). While the extent of distributions of these species is relatively large, they are often patchily distributed in populations that are small; in addition, both gartersnake species are listed as threatened under the Endangered Species Act. Aside from detrimental effects...
