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.
The Alaska CSC is supporting a variety of projects aimed at understanding, predicting and adapting to the impacts of climate variability and climate change on Alaska's resources. Examples of these projects include:
Western Alaska Coastal Hazards Workshop: Jointly sponsored by the Alaska CSC, Alaska Ocean Observing System, and Western Alaska LCC, May 30-31, 2012.
In addition to the "fact sheets" offered above, here are some samples of the technical publications that are resulting from this work:
