Humboldt Bay Dune Restoration

The Refuge’s Lanphere Dunes Unit is home to the first dune restoration project on the west coast. Restoration began in the 1980s with early experiments to control invasive European beachgrass (Ammophila arenaria). By the early 1990s The Nature Conservancy (the past owner) began a large-scale mechanical eradication project that took 6 years to complete. This project became a template for dune restoration projects throughout the west coast and beyond.

Integrating Climate Change in Transportation and Land Use Scenario Planning: An Example from Central New Mexico

The Central New Mexico Climate Change Scenario Planning Project, an Interagency Transportation, Land Use, and Climate Change Initiative, utilized a scenario planning process to develop a multiagency transportation- and land use-focused development strategy for the Albuquerque region of New Mexico to achieve a reduction in future greenhouse gas emissions and to prepare for the potential impacts of climate change on the region.

FHWA Climate Resilience Pilot Program: Capital Area Metropolitan Planning Organization (CAMPO)

The Capital Area Metropolitan Planning Organization (CAMPO) covers a six-county region in Central Texas that includes the City of Austin. The area is rapidly growing, and extreme weather events—notably floods, droughts, extreme heat, wildfire, and extreme cold—are an added stressor on the region’s multi-modal transportation system. For this project, CAMPO partnered with the City of Austin Office of Sustainability to assess vulnerabilities to critical transportation assets in the region.

FHWA Climate Resilience Pilot Program: California Department of Transportation District 1

The California Department of Transportation (Caltrans) road system is important for access, particularly in northern California where impacts to highways and limited availability of alternate routes have isolated populations during past extreme weather events. Caltrans District 1, in cooperation with the Humboldt County Association of Governments, assessed criticality of assets and potential impact to screen for vulnerability. The vulnerability assessment approach drew from methodologies developed by FHWA and the Washington State DOT 2010-2011 climate resilience pilot project.

FHWA Climate Resilience Pilot Program: Arizona Department of Transportation

Arizona Department of Transportation conducted a pilot study to identify hotspots where highways are vulnerable to extreme weather, including high temperatures, drought, and intense storms. These factors can contribute to dust storms, wildfire, and flash floods, depending on the surrounding vegetation and landscape. The risks are different in the lower desert and grassland areas than in the forested mountain portions of the state.

A Window of Opportunity for Climate-Change Adaptation: Easing Tree Mortality by Reducing Forest Basal Area

Increasing aridity as a result of climate change is expected to exacerbate tree mortality. Reducing forest basal area – the cross-sectional area of tree stems within a given ground area – can decrease tree competition, which may reduce drought-induced tree mortality. However, neither the magnitude of expected mortality increases, nor the potential effectiveness of basal area reduction, has been quantified in dryland forests such as those of the drought-prone Southwest US.
