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.

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.
This is a list of no-cost sources that list or index electronic texts, including journal articles or reports. At these sites you'll find electronic books, journal articles, scientific and technical reports, conference papers, fact sheets, news transcripts, preprints, theses and dissertations. Many provide the full texts online, or abstracts, while others merely list bibliographic citations.
Employees of the U.S. Department of the Interior are reminded they may also search for journal articles by using EBSCO Online, GREENR, JSTOR, or Science Direct. Most employees may search these databases at their desks, while others must come to the Library or contact a Reference Librarian for assistance.
