Spring is coming early in 3/4 of national parks, according to a new study. Awesome? Not so much. As flowers bloom earlier every year, it’s disrupting the link between the wildflowers and the arrival of birds, bees, and butterflies that feed on and pollinate the flowers. In Shenandoah, an earlier spring is giving invasive plants a head start, and they’re displacing native wildflowers, leading to costly management issues.
Before the 1960s almost everything about living openly as a lesbian, gay, bisexual, or transgender (LGBT) person was illegal. New York City laws against homosexual activities were particularly harsh. The Stonewall Uprising on June 28, 1969 is a milestone in the quest for LGBT civil rights and provided momentum for a movement.
Vine Creek Ranch at Death Valley National Park. Steady drought and record summer heat make Death Valley a land of extremes. Towering peaks are frosted with winter snow. Rare rainstorms bring vast fields of wildflowers. Lush oases harbor tiny fish and refuge for wildlife and humans. Despite its morbid name, a great diversity of life survives in Death Valley.
Located 2,600 miles southwest of Hawaii, the National Park of American Samoa is the most remote unit of the National Park System and the U.S. National Park south of the Equator. The Park spreads across three islands, 9,500 acres of tropical rainforest, and 4,000 acres of ocean, including coral reefs. While remote, the islands of American Samoa, true to the meaning of the word Samoa (Islands of Sacred Earth), are welcoming and offer beautiful landscapes and centuries of culture and history.

Extended Monitoring and Modeling of Climate Change Effects on Pacific Northwest Wetlands

Wetlands are ecologically important yet at-risk ecosystems. Wetlands provide critical services for natural communities and human society, including nutrient cycling, wildlife provisioning, water storage & filtration, carbon sequestration, agriculture & recreation, and core habitat for a wide range of species. Wetlands challenge our current scientific capacity because of their sheer number (10,000's-100,000's for the Pacific Northwest alone), their wide range of sizes (10,000 m2), and dynamic nature (intermittent to permanent). They are also thought to be among the most sensitive ecosystems to climate change via changes in temperature and precipitation and resulting changes in hydroperiod and water temperature. Our research aims to develop new approaches and technical tools that are needed to support the conservation and sustainable management of wetlands in a changing climate. These include: 1) new methods for mapping wetlands and monitoring and reconstructing wetland hydroperiod using remote- sensing approaches, 2) the first generation of projections of hydrologic impacts to Pacific Northwest wetlands under climate change, 3) field-based hydrologic monitoring of wetlands in three PNW ecoregions, and 4) integration of 1-3 with ecological data to forecast climate change impacts to wetland ecosystems. We are particularly interested in the effects of climate change on amphibians such as the Cascades frog.
