Using a geographic dataset of structures, with more than 5500 structures that were destroyed or damaged by wildfire since 2001, we identified the main contributors to property loss in two extensive, fire-prone regions in southern California.
Shows how observations and modeling can help anticipate practical problems in coastal areas when hurricanes arrive. Focuses primarily on areas where people have built houses and roads that may be destroyed during storms.

Describes the types of concerns and observations used to help area resource managers analyze actual or potential changes in this highly developed ecosystem.
Study to identify grasslands that may be suitable for cellulosic feedstock production. Producing ethanol from non-cropland areas such as grassland will minimize the effects of biofuel developments on global food supplies.
