WASHINGTON, D.C. -- The U.S. Department of Homeland Security's Federal Emergency Management Agency announced that federal disaster aid has been made available to the Commonwealth of Kentucky and ordered federal aid to supplement commonwealth and local recovery efforts in the area affected by severe storms, tornadoes, flooding, landslides, and mudslides during the period of April 2-17, 2015.

WASHINGTON – Wildfires can occur anywhere in the country with the potential to destroy homes, businesses, infrastructure, natural resources, and agriculture. Last year, the United States experienced over 63,000 wildfires that burned more than three million acres. National Wildfire Community Preparedness Day is Saturday, May 2, and people across the nation will dedicate time to making their communities a safer place should a wildfire occur.Language English
SEATTLE, Wash. — More than 1,000 dams have been removed across the United States because of safety concerns, sediment buildup, inefficiency or having otherwise outlived usefulness. A paper published today in Science finds that rivers are resilient and respond relatively quickly after a dam is removed.
“The apparent success of dam removal as a means of river restoration is reflected in the increasing number of dams coming down, more than 1,000 in the last 40 years,” said lead author of the study Jim O’Connor, geologist with the U.S. Geological Survey. “Rivers quickly erode sediment accumulated in former reservoirs and redistribute it downstream, commonly returning the river to conditions similar to those prior to impoundment.”
Dam removal and the resulting river ecosystem restoration is being studied by scientists from several universities and government agencies, including the USGS and U.S. Forest Service, as part of a national effort to document the effects of removing dams. Studies show that most river channels stabilize within months or years, not decades, particularly when dams are removed rapidly.
“In many cases, fish and other biological aspects of river ecosystems also respond quickly to dam removal,” said co-author of the study Jeff Duda, an ecologist with USGS. “When given the chance, salmon and other migratory fish will move upstream and utilize newly opened habitat.”
The increase in the number of dam removals, both nationally and internationally, has spurred the effort to understand the consequences and help guide future dam removals.
“As existing dams age and outlive usefulness, dam removal is becoming more common, particularly where it can benefit riverine ecosystems,” said Gordon Grant, Forest Service hydrologist. “But it can be a complicated decision with significant economic and ecologic consequences. Better understanding of outcomes enables better decisions about which dams might be good candidates for removal and what the river might look like as a result.”
Sponsored by the USGS John Wesley Powell Center for Analysis and Synthesis, a working group of 22 scientists compiled a database of research and studies involving more than 125 dam removals. Researchers have determined common patterns and controls affecting how rivers and their ecosystems respond to dam removal. Important factors include the size of the dam, the volume and type of sediment accumulated in the reservoir, and overall watershed characteristics and history.

WASHINGTON, D.C. – The U.S. Department of Homeland Security's Federal Emergency Management Agency announced that federal disaster aid has been made available to the Commonwealth of Kentucky to supplement commonwealth and local recovery efforts in the area affected by the severe winter storms, snowstorms, flooding, landslides, and mudslides during the period of February 15-22, 2015.Language English
DENVER – Thursday, April 30, is America’s PrepareAthon! National Day of Action, a grassroots campaign for action to get families, organizations and whole communities better prepared for emergencies. The campaign offers easy-to-use preparedness guides, checklists, and resources to help individuals prepare for common natural hazards and to take action, including downloading alerts and warnings, holding a drill, or safeguarding critical documents.Language English

Sixty Percent of Americans Not Practicing for Disaster: FEMA urges everyone to prepare by participating in National PrepareAthon! Day on April 30
WASHINGTON – A recent Federal Emergency Management Agency (FEMA) survey found that nearly 60 percent of American adults have not practiced what to do in a disaster by participating in a disaster drill or preparedness exercise at work, school, or home in the past year. Further, only 39 percent of respondents have developed an emergency plan and discussed it with their household.Language English
EVERGLADES NATIONAL PARK, Fla.— The largest and longest Burmese Python tracking study of its kind -- here or in its native range -- is providing researchers and resource managers new information that may help target control efforts of this invasive snake, according to a new study led by the U.S. Geological Survey.
Among the findings, scientists have identified the size of a Burmese python’s home range and discovered they share some “common areas” that multiple snakes use.
“These high-use areas may be optimal locations for control efforts and further studies on the snakes’ potential impacts on native wildlife,” said Kristen Hart, a USGS research ecologist and lead author of the study. “Understanding habitat-use patterns of invasive species can aid resource managers in designing appropriately timed and scaled management strategies to help control their spread.”
Using radio and GPS tags to track 19 wild-caught pythons, researchers were able to learn how the Burmese python moved within its home range. The 5,119 days of tracking data led researchers to conclude that python home ranges are an average of 22 square kilometers, or roughly an area 3 miles wide-by-3 miles long, all currently within the park.
The study found pythons were concentrated in slough and coastal habitats, with tree islands being the principal feature of common-use areas, even in areas where they were not the predominant habitat type. The longest movements of individual pythons occurred most often during dry conditions, but took place during “wet” and “dry” seasons.
Burmese pythons are long-lived, large-bodied constricting snakes native to Southeast Asia. Highly adaptable, these ambush predators can reach lengths greater than 19 feet and produce large clutches of eggs that can range from eight to 107 eggs. Burmese pythons were first observed in South Florida’s Everglades National Park in 1979. Since then, they have spread throughout the park. Although recent research indicates the snakes may be having a significant effect on some populations of mid-sized mammals, it has also shown there is little risk to people who visit Everglades National Park.
Invasive species compete with native wildlife for food, and they threaten native biodiversity across the globe. With nearly 50 percent of the imperiled species in the US being threatened by exotic species, a major concern for land managers is the growing number of exotics that are successfully invading and establishing viable populations.
Florida is home to more exotic animals than any other state. Snakes in particular have been shown to pose a high risk of becoming invasive species. The establishment of Burmese pythons in South Florida poses a significant threat to both the sensitive Everglades ecosystem and native species of conservation concern. For example, in the park, wood storks, Florida panthers and Cape Sable seaside sparrows are all species of conservation concern that have home ranges near the common-use areas of the radio-tracked pythons.
The study, “Home Range, Habitat Use, and Movement Patterns of Non-Native Burmese Pythons in Everglades National Park, Florida, USA,” with authors from the USGS, University of Florida, National Park Service, and Davidson College, was published in the journal Animal Biotelemetry.
