Applied Landscape Ecology and Remote Sensing
We focus on landscape studies of natural and working lands, in particular coastal and inland wetlands and rangelands. We quantify ecosystem benefits, find areas vulnerable to future change, and identify potential for climate mitigation and resilience. We conduct research by scaling field measurements to the regional, state and national scale with remote sensing, geospatial analysis, and modeling...
Patterns in the Landscape – Analyses of Cause and Effect
Understanding the rates and causes of land-use/land-cover (LULC) change helps answer questions about what, where, how, and why the Earth’s surface is changing. Land-surface change results from human activities or natural processes like floods, droughts, and wildfires, and many of these change processes are observable in satellite imagery. The growing historical catalog of satellite images allows...
Buffelgrass
Mapping When and Where Invasive Buffelgrass is Green at Saguaro National Park in Arizona.
Ecosystem Modelling and Decision Support
The Ecosystem Modelling and Decision Support Project seeks to understand how drivers of ecosystem change like wildfire, drought, and land use affected past spatial and temporal patterns of vegetation communities and wildlife. Research methods involve 1) analyzing field-collected information (e.g. long-term plot/transect data, repeat photography) on soils, vegetation, and/or wildlife with...
Integrated Wildland Fire Science
The size and number of large wildland fires in the western United States have grown dramatically over the past decade, with a contingent rise in damages and suppression costs. This trend will likely continue with further growth of the wildland urban interface (WUI) into fire prone ecosystems, hazardous fuel conditions from decades of fire suppression, and a potentially increasing effect from...
Land Use and Climate Change Team
We are a research team focusing 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. We are interested in how land-use and climate systems will...
Land Cover Trends
Land Cover Trends was a research project focused on understanding the rates, trends, causes, and consequences of contemporary U.S. land use and land cover change. The project spanned from 1999 to 2011. The research was supported by the Climate and Land Use Change Research and Development Program of the U.S. Geological Survey (USGS) and was a collaborative effort with the U.S. Environmental...
Dasymetric Mapping
By using the USGS- developed, GIS-based tool, we can automate the dasymetric mapping process. We have worked with various communities to create accurate population density maps to aid in risk and vulnerability analysis linked to natural hazards. By using the USGS- developed, GIS-based tool, we can automate the dasymetric mapping process. We have worked with various communities to create accurate...
