An All Taxa Biodiversity Inventory is essentially an attempt to document all the species of life within a given area. But it goes much further, determining the interactions between species and how these communities change with time.
We anticipate developing relationships between vegetative health and biodiversity, perhaps spatial patterns of species richness, and GIS-based methodologies for biodiversity conservation planning.
These data may also provide for additional ecological research and data-driven environmental policy.
The Laurel River in Western North Carolina drains 133 mi² of Madison County, with approximately 90% of the watershed being forested. Fifty-nine miles of the border between North Carolina and Tennessee are within the Appalachian Trail National Park.
These very small headwater streams along the AT provide the organic material needed to drive the ecosystem's health downstream. Madison County may be the Jewel of the Blue Ridge, but the Laurel River is its diamond.
Despite the unique qualities of this watershed, very little data have been collected:
⦁ The NC Division of Water Resources has collected data from only 10 sites, with only one site sampled more than once
⦁ A citizen science monitoring program (Stream Monitoring Information Exchange Program) collects data annually from the Laurel River near Belva
⦁ All existing data have resulted in 'Excellent' or 'Good' bio-classifications using the protocols of the Division of Water Resources
The Laurel River watershed is the richest and most diverse tributary of the Lower French Broad watershed and provides a steadfast refuge for the recolonization of other tributaries and the French Broad itself.
Despite its unique qualities, the Laurel River is not immune to:
⦁ The effects of climate change
⦁ Development pressures
⦁ Massive natural disasters such as longer, more severe droughts
⦁ Higher-intensity rainfall eventsImpact from non-native species on watershed diversity
We hope to mirror, to some extent the work being done in the Great Smoky Mountains National Park. The Smokies All Taxa Biodiversity Inventory (ATBI) has doubled the number of species known in the park from around 10,000 species when the project began in 1998, to now more than 21,000 species. These include over 11,000 species that represent new records for the park and more than 1,000 species that are new to science!
The executive director of the WREN Center and members of the Board of Directors are trained scientists and will lead the initiative initially. However, we recognize that grant money will be necessary to fund trained taxonomists in other fields.
The WREN staff will select:
⦁ A minimum of 5 terrestrial plots of 10 m² with permission and encouragement of private landowners
⦁ Hopefully public plots within the National Forest as well
⦁ A minimum of 5 aquatic sites at several stream orders (watershed sizes)
⦁As many education sites as possible, located on school properties or educational venues
Collection protocols will be developed for each taxonomic working group (or TWIG), and samples will be collected to document the greatest diversity during the most productive seasons for each TWIG.
This initiative is the first of its kind outside of the Great Smoky Mountains National Park. The Laurel River ATBI represents a groundbreaking opportunity to understand and preserve one of Western North Carolina's most important watersheds.
