More Streams Mapped by Smokies Scientists and USGS with Modern Technology

Great Smoky Mountains National Park geographic information system specialists and scientists in collaboration with scientists from Tennessee, North Carolina, and the United States Geological Survey (USGS), completed a three-year stream mapping project. Park scientists used a combination of aircraft-mounted scanners and a Global Positioning System verification system to re-inventory streams throughout the park.

Using this modern mapping technology, scientists determined the park contains 2,900 miles of streams. Of these, 1,073 miles of streams are large enough to support fish. Previously, using topographic maps, the scientists estimated there to be approximately 2,000 miles of streams in the park. A water features is considered a stream if it exhibits the hydrologic, geomorphologic, and biologic characteristics of moving water at least part of the year.
 
Working with the USGS, the park incorporated the new stream data into the National Hydrography Dataset (NHD) which allows the researchers and the public real-time access to detailed information about streams across the nation. Park staff and research partners rely heavily upon the accurate information in the NHD to manage park water quality and aquatic ecosystem health. The NHD data is accessible via The National Map at http://viewer.nationalmap.gov/viewer/ and re-mapped streams within the park can be seen at http://www.nps.gov/npmap/park-tiles/#10/35.6032/-83.4659.

Park Changes Firewood Regulations, Only Heat-Treated Allowed in Campgrounds

Great Smoky Mountains National Park officials have announced regulation changes that will help protect park forests by limiting the type of firewood brought into the park. Beginning in March 2015, only heat-treated firewood that is bundled and displays a certification stamp by the USDA or a state department of agriculture will be allowed for use in park campgrounds.
 
Heat-treated firewood will be available to purchase from concessioners in many of the campgrounds as well as from private businesses in the communities around the park. Certified heat-treated firewood is packaged in 0.75 cu-ft. bundles clearly displaying a certification stamp. The wood is a high-quality hardwood product that has been heated for 60 minutes at 140 degrees Fahrenheit. The wood lights easily, burns well for campfires, is safe to cook over, and is already available at over 85 locations near the park that can be viewed on an interactive map by visiting www.nature.org/firewoodmap. In addition, visitors may still collect dead and down wood in the park for campfires.
 
“The threat of these new pests coming into our forests, both in the park and regionally, compels us to do all we can to reduce the risk to our forests,” said Acting Superintendent Clayton Jordan. “While a ban on the importation of non-treated firewood will not entirely halt the spread of destructive forest pests and diseases, it will greatly slow it down. This allows time to develop and implement new treatment strategies to help control the impacts from these non-native pests and diseases.”
 
Non-native, tree-killing insects and diseases can unknowingly be introduced through firewood transported from infested areas. A variety of destructive pests lay eggs or stowaway in firewood. These insects from Asia and Europe have the potential to devastate over 30 species of hardwood trees native to the park. New infestations threaten our forests with widespread tree mortality that could devastate wildlife habitat, biodiversity, and scenic views. The use of firewood that has been heat treated eliminates the threat posed by these pests through the movement and use of wood in campfires.
 
National parks throughout the Appalachian region have taken action to limit the spread of insect pests in firewood including, in many cases, the banning of imported firewood. For the past three years, the Smokies has prohibited the importation of firewood from areas quarantined by the USDA Animal Plant Health Inspection Service. Park rangers have been working over the past year with numerous partners representing federal and state agencies, conservation organizations, and universities to mitigate the risks associated with movement of firewood including a public education campaign with campground programs and regionally placed billboards. The park also hosted public meetings and developed an informational handout that was provided to all Smokies campers throughout the summer inviting public comments.
