The Great Dismal Swamp (GDS) project is an application of USGS LandCarbon, at the US Fish and Wildlife Service's (FWS) Great Dismal Swamp National Wildlife Refuge (NWR), and is designed to produce local-scale carbon estimates (including fluxes, ecosystem balance, and long-term sequestration rate) to include in an ecosystem service assessment in support of Department of Interior (DOI) land management activities. The project will improve the understanding of the effects of past drainage, logging, farming, and management on carbon sequestration and fire risk in peatlands. Broad Science Questions: How are ecosystem services (including carbon sequestration, wildlife viewing, water quality, and others) impacted by management...

Landslides are a common hazard on FSM and identified as a significant risk to human life by the CDC. In 1997, tropical storms (TS) triggered landslides in Pohnpei that resulted in 20 fatalities, impacting 14 homes. In 2002, a TS triggered over 250 landslides in Chuuk resulting in 47 fatalities and impacting 231 structures, totaling $100 million in damages. FSM has also been impacted by disastrous landslides in 1991, 1992, 2004, and 2018 – and certainly many other unreported landslides. Following the 2002 event, the CDC found that “increasing knowledge of natural warnings can reduce the risk for mortality during landslides.” As a first step, knowing what areas are susceptible to landslide hazards is key. To this...

A one-dimensional daily averaged water temperature model was used to simulate Klamath River temperatures for two management alternatives under historical climate conditions and six future climate scenarios. The analysis was conducted for the Secretarial Determination on removal of four hydroelectric dams on the Klamath River. In 2012, the Secretary of the Interior will determine if dam removal and implementation of the Klamath Basin Restoration Agreement (KBRA) (Klamath Basin Restoration Agreement, 2010) will advance restoration of salmonid fisheries and is in the public interest. If the Secretary decides dam removal is appropriate, then the four dams are scheduled for removal in 2020.

This research focuses on understanding the rates, causes, and consequences of land change across a range of geographic and temporal scales. Our emphasis is on developing alternative future projections and quantifying the impact on environmental systems, in particular, the role of land-use change on ecosystem carbon dynamics. This project supports the development of the Land-use and Carbon Scenario Simulator (LUCAS) model. LUCAS tracks changes in land use, land cover, land management, and disturbance, and their impacts on ecosystem carbon storage and flux by combining: A State-and-Transition Simulation Model (STSM) to simulate changes in land-use across a range of geographic scales. A Stock and Flow Model to track...

Understanding the distribution and gaps in distribution for invertebrates that serve as prey items for waterbirds in the Great Basin is proving to be a successful way of understanding how prey availability may change as climate-induced changes to salinity in wetlands vary across the Great Basin. The molecular work for this project is coupled with a concurrent study of Great Basin wetlands, water chemistry, climate models, and waterbird use of the area to provide a robust picture of current and future conditions.
Predicted climate impacts on arid U.S. Great Basin wetlands will alter their number, distribution, and quality (e.g., salinity). The scarcity and isolation of these wetlands make them essential not only to wildlife but to ranchers, farmers, and urban areas that rely on their ecosystem services. Great Basin wetlands are important habitats for migratory birds at high volumes, but they become concentrated mineral brines at low volumes, narrowing waterbird food resources as salinity rises. Thus, many resource managers need to answer two questions: How will climate change affect migratory bird species dependent on climate-sensitive wetlands? How should management strategies balance human-consumer uses of these water...
