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.
Interior Announces New Method to Measure Potential for Carbon Storage in U.S. Lands -- and Reduce Greenhouse Gas Emissions to the Atmosphere
Last edited 4/25/2016
WASHINGTON, DC — A new methodology to assess the potential to store carbon in U.S. wetlands, forests and rangelands ecosystems--and thus to reduce emissions of greenhouse gases to the atmosphere—will help find ways to mitigate the impacts of climate change, the Department of the Interior announced today.
“This new research by scientists from Interior's U.S. Geological Survey is a cutting-edge development that will inform land management policies and planning for the long-term storage of carbon to help lessen the impacts of climate change,” Deputy Secretary of the Interior David J. Hayes said today. “This innovative initiative, which Congress called on Interior to undertake in 2007 energy legislation and which Secretary Salazar outlined at the 2009 Copenhagen climate conference, will improve the nation's understanding of amounts, sources, and transport of carbon at scales suitable for use by land managers and decisionmakers.”
“Using this methodology, the USGS will now be able to conduct a national assessment to determine how much carbon is being stored in ecosystems and to estimate the capability to use natural systems – such as wetlands, forests and rangelands – to absorb greenhouse gases. The assessment will be conducted on a regional basis,” said USGS scientist Zhiliang Zhu.
The process of removing carbon from the atmosphere and storing it in vegetation, soils and aquatic environments is known as biological carbon sequestration. The movement of greenhouse gases in ecosystems results from natural ecosystem processes and human activities. This assessment accounts for three gases, which are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O).
As part of the national assessment, USGS scientists are evaluating major processes that affect carbon sequestration capability and greenhouse gas emissions. Those processes include climate change, changes in land use and land cover, changes in land management activities, and ecosystem disturbances such as wildfires.
This methodology incorporates public comments that were solicited on a draft methodology published in July 2010. It also builds upon the USGS rapid assessment report published in December 2009 to estimate the carbon storage potential in the nation's forests and soils. The new methodology focuses on all of the nation's ecosystems and incorporates data and methods (including land use and biogeochemical models and aquatic models) that were updated since the rapid assessment was published. This methodology also incorporates suggestions from an interagency science panel, an extensive peer-review process and comments from other federal agencies.
In addition, the USGS is conducting research on a number of other fronts related to carbon sequestration. These efforts include evaluating the potential for storing carbon dioxide in geologic formations below Earth's surface, potential release of greenhouse gases from Arctic soils and permafrost, and mapping the distribution of rocks suitable for potential mineral sequestration efforts.
The methodology was developed in accordance with the Energy Independence and Security Act of 2007, which directed the Department of the Interior to develop the methodology and conduct the national assessment. This research also benefited from discussions with a variety of organizations and stakeholders, such as the Department of Agriculture (particularly the U.S. Forest Service) and Department of Energy, the Environmental Protection Agency and the science community.
