Overview of Nisqually River Delta ecosystem services modeling

One of the major ecological consequences of increasing global connectivity is the introduction, establishment, and spread of non-native species into new ecosystems. The rate and extent of biological invasions continues to increase globally, often at considerable environmental and economic costs. Once established, non-native species can transform ecosystems, complicating land management decision...

Oil and gas development across the western United States has increased substantially in recent decades, including within the Colorado Plateau. The Colorado Plateau is a high desert region of grasslands, shrublands, and woodlands and is home to a large number of world-renowned national and tribal parks and monuments (e.g., Grand Canyon, Zion, Bryce, Arches, Canyonlands, Monument Valley, and Mesa...

San Carlos Apache Reservation covers 1.8 million acres in east-central Arizona, and has diverse ecosystems and vegetation types that support a natural resource-based economy.

Mapping When and Where Invasive Buffelgrass is Green at Saguaro National Park in Arizona.

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...
