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 plantings of cherry trees originated in 1912 as a gift of friendship to the People of the United States from the People of Japan. In Japan, the flowering cherry tree, or "Sakura," is an exalted flowering plant. The beauty of the cherry blossom is a potent symbol equated with the evanescence of human life and epitomizes the transformation of Japanese culture throughout the ages.
Carbon Storage in U.S. Eastern Ecosystems Helps Counter Greenhouse Gas Emissions Contributing to Climate Change

Interior Releases Report on Anniversary of President's Climate Action Plan; New Visualization Tool Helps Land Managers Make Smart, Informed Landscape-Level Decisions

WASHINGTON, D.C.– On the one-year anniversary of President Obama'sClimate Action Plan, Secretary of the Interior Sally Jewell today released anew reportshowing that forests, wetlands and farms in the eastern United States naturally store 300 million tons of carbon a year (1,100 million tons of CO2),which is nearly 15 percent of the greenhouse gas emissions EPA estimates the country emits each year or an amount that exceeds and offsets yearly U.S. car emissions.
In conjunction with the national assessment, today USGS also released a newweb tool, which allows users to see the land and water carbon storage and change in their ecosystems between 2005 and 2050 in the lower 48 states. This tool was called for in the President's Climate Action Plan.
“Today we are taking another step forward in our ongoing effort to bring sound science to bear as we seek to tackle a central challenge of the 21st century – a changing climate,” said Secretary Jewell. “This landmark study by the U.S. Geological Survey provides yet another reason for being good stewards of our natural landscapes, as ecosystems play a critical role in removing harmful carbon dioxide from the atmosphere that contributes to climate change.”
With today's report on the eastern United States, the U.S. Geological Survey (USGS) has completed the national biological carbon assessment for ecosystems in the lower 48 states – a national inventory of the capacity of land-based and aquatic ecosystems to naturally store, or sequester, carbon, which was called for by Congress in 2007.
Together, the ecosystems across the lower 48 states sequester about 474 million tons of carbon a year (1,738 million tons of CO2), comparable to counter-balancing nearly two years of U.S. car emissions, or more than 20 percent of the greenhouse gas emissions EPA estimates the country emits each year.
The assessment shows that the East stores more carbon than all of the rest of the lower 48 states combined even though it has fewer than 40 percent of the land base. Under some scenarios, USGS scientists found that the rate of sequestration for the lower 48 states is projected to decline by more than 25 percent by 2050, due to disturbances such as wildfires, urban development and increased demand for timber products.
“What this means for the future is that ecosystems could store less carbon each year,” said USGS Acting Director Suzette Kimball. “Biological sequestration may not be able to offset greenhouse gas emissions nearly as effectively when these ecosystems are impaired.”
Forests accounted for more than 80 percent of the estimated carbon sequestered in the East annually, confirming the critical role of forests highlighted in the Administration's climate action initiative.
USGS scientists have been building the national assessment since a 2007 congressional mandate in the Energy Independence and Security Act. The first report, on theGreat Plains, was released in 2011, the second report, on theWestern United States, was released in 2012. Reports on Alaska and Hawaii are expected to be completed in 2015.
Biological carbon storage – also known as carbon sequestration – is the process by which carbon dioxide (CO2) is removed from the atmosphere and stored as carbon in vegetation, soils and sediment. The USGS inventory estimates the ability of different ecosystems to store carbon now and in the future, providing vital information for land-use and land-management decisions. Management of carbon stored in our ecosystems and agricultural areas is relevant both for mitigation of climate change and for adaptation to such changes.
The area studied for the eastern U.S. carbon assessment was defined by similarities in ecology and land cover. The study area extends eastward from the western edge of the Great Lakes and the Mississippi floodplains, across the Appalachian Mountains, to the coastal plains of the Atlantic Ocean and the Gulf of Mexico. The major ecosystems USGS researchers evaluated were terrestrial (forests, wetlands, agricultural lands, shrublands and grasslands), and aquatic (rivers, lakes, estuaries and coastal waters).
