Madagascar, a country rich in natural capital and biodiversity but with high levels of poverty, food insecurity, and population growth, faces a number of development challenges, including obtaining sustained financial support from external sources and building internal capacity to address the poor environmental, health, and socio-economic conditions. Climate change poses an increasing threat to ac

The Southwest is projected to face significant climate challenges in coming decades; and many of these stresses have already begun. In recent years, multiple climate assessments have been developed for the Southwest that corroborate forecasts of remarkable change to vegetation pattern and the vulnerability of regional ecosystems and suggest that measurable change is already ongoing. Disturbance ev

California is a world biodiversity hotspot, and also home to hundreds of sensitive, threatened, and endangered species. One of the most vulnerable ecosystems in California is the “sky island” montane forests of southern California, forests of conifers and hardwoods located only in high-elevation mountain regions. Montane forests serve many important ecosystem functions, including protecting the up

The Northeast U.S. coast is experiencing some of the fastest rates of sea level rise in the world. The Boston Harbor Islands National Recreation Area is particularly at risk from sea level rise and coastal storm impacts. Erosion and storm impacts have already led to the degradation of shoreline habitats and protective structures (e.g., sea walls), as well as direct impacts to historic landmarks on

Over two-thirds of all landbirds (i.e. birds that spend the majority of their lives in terrestrial environments) in North America migrate long-distances to areas in Mexico, Central and South America and the Caribbean islands. Habitats within Texas and Louisiana support high numbers of birds when they interrupt their migratory journeys through the Gulf of Mexico region to “stopover” for resting and

Species are on the move as they respond to climate change. This includes many native species, but also species with high costs to society such as disease vectors, pests, and nonnative invasive species (an invasive species is a species that is not native to a specific location but is spreading with the tendency of causing damage to native plants and animals). Currently there are hundreds of invasiv

Trout are one of the most culturally, economically, and ecologically important groups of freshwater fishes in the Rocky Mountain region. However, human impacts and climate change are significantly altering freshwater ecosystems that support native trout species. Despite their broad importance, many of the region’s trout populations are threatened and some require immediate conservation efforts to

Several times during the severe drought of 2010-2015, communities within the jurisdictional territories of the Chickasaw Nation and the Choctaw Nation of Oklahoma were precariously close to running out of water. According to previous studies, temperatures are expected to continue to rise throughout the southern states, and droughts are predicted to be longer and more severe. Even small changes to

Moose are an economically and culturally important species in Minnesota. Like many species, however, moose are experiencing reductions in distribution and abundance across the Midwest as a result of climate change and habitat loss. Moose populations have declined by 60% since 2006, in part because of thermal heat stress in warming summers and increased frequency of contact with white-tailed deer t

Ponderosa pine forests are declining and their future persistence is uncertain. Most research on forest declines has focused on the effects of disturbances including wildfire, insect outbreaks, and severe drought on mortality of mature trees. Yet, recent research suggests that ponderosa pine declines may be even more severe as these ecosystems fail to regenerate naturally (i.e. grow from seed to a

Alaska is an ecologically, commercially, and recreationally diverse state, providing value to people and terrestrial and aquatic species alike. Presently, Alaska is experiencing climatic change faster than any other area of the United States, but across the state, comprehensive environmental monitoring is logistically difficult and expensive. For instance, only about 1% of U.S Geological Survey (U

The climate of the Southeast is changing rapidly. As streams warm and streamflow dynamics change due to climate and land-cover changes, previously unsuitable habitats may become hospitable for invasive species. Warmwater and large-river adapted invasive species such as Asian carps may move upstream as habitats that were previously too cold or had too little flow become welcoming environments for t
