ATBI Living Resources Classification System - The Top Tiers

ATBI Living Resources Classification System - The Top Tiers

Water BearSnailMoth

  • The Smokies are renowned for diversity on a variety of levels -- from plant communities and habitats to species and genetic variation. Non-microbial species estimates in the park vary from about 50,000 to 100,000. Over 18,000 are currently known.
  • The All Taxa Biodiversity Inventory (ATBI) seeks to discover the others -- including the smaller creatures that are the hidden, but crucial members of the ecosystem. Many are so small that most microscopes are not adaquate to view them. The ATBI also seeks to reveal critical ecological connections between soils, geology, and habitats.
  • As project scientists continue to make discoveries, we will be updating our classification pages and species information. In biological terminology, this classification system is known as a "taxonomic system" or "taxonomy". Each individual level of this hierarchical system is called a "taxon."
  • In the following table the top level taxa of park organisms are listed. However, the classification outlined below may change as this web page is updated to reflect current scientific understanding of the relationships between organisms. The links in the Kingdom column will allow you to venture into the next lower level of taxa applicable to the specific taxa term clicked.
  • Now Discover Life in America invites you to venture into the fascinating realm of organisms that have been discovered inhabiting our Great Smoky Mountains National Park!

Note: These taxa pages are a work-in-progress. The fact that particular taxa cannot be found on our hierarchial taxa lists does not mean that the organisms are not inhabiting the park. Your help in identifying these missing taxa, and then presenting science-based proposals and funding for inventorying these hidden, yet intrinsically valuable life forms is much appreciated by the DLIA staff and Board of Directors, as well as the Park's Inventory and Monitoring personnel.

Thank you for a great 2014 ATBI Conference

Thank you to all who participated in, and attended our annual ATBI Conference of March 2014. We believe it was very profitable: not only for the attendees in general, but for the gathering and collaboration of experts in the field of conservation biology. We were also delighted and enthused by the presence and presentations of our keynote speaker, bat conservationist and author, Dr. Merlin Tuttle.

Thank you Dr. Tuttle!
