Documenting Beetle Diversity in Great Smoky Mountains National Park
The Coleoptera Taxonomic Working Group (TWIG) at the Louisiana State Arthropod Museum
Christopher Carlton, TWIG Coordinator

Overview
Several years ago a plan was initiated to survey all
organisms within the boundaries of Great Smoky Mountains National Park (GSMNP).
The effort is being conducted by biologists at Great
Smoky Mountains National Park and independent taxonomic specialists in cooperation with, and supported by, the non-profit organization Discover Life in America.
By far the most diverse group of organisms in the park
will be the insects, and within insects the most diverse order will be the Coleoptera,
or beetles. The initial
stages of this ambitious project were implemented as a structured collecting
strategy conducted "in-house" with subsequent field expertise
provided by U.S. and international specialists. Insect sampling was conducted at intervals of every
two weeks at 11 sites within GSMNP using Malaise traps, Lindgren funnel traps,
and pitfall traps. At intervals of every six months these methods were supplemented
using Berlese extraction and ground pans. These sampling methods were conducted from late 2000-2003. The resulting specimens
were sorted to the ordinal
level by biologists at GSMNP and now represent the focal groups for finer level identification by the various cooperators.

Protocol
Samples of Coleoptera will be shipped to the LSAM as they accumulate during
the in-house portion of the project and supplemental efforts (e.g., "Beetle and Litter Blitzes" conducted during June
2001, July 2003, and July 2004). We will sort the Coleoptera to lower
taxonomic levels (families, tribes, genera, etc.), and will sort to species
certain taxa that we are proficient at identifying. Remaining sorted fractions
will be shipped to collaborators who will process them further, ultimately identifying
them to species. The final disposition of data and specimens is as follows:
Exemplars of identified taxa, including uniques, are to be returned to GSMNP for permanent deposition. Specimen data are to be
forwarded to the Southern Appalachian Information Node (SAIN), a part of the National Biological Information Infrastructure (NBII). Duplicate exemplars may be retained by the identifiers. The LSAM
is maintaining a simplified species checklist posted on this website to allow
continual tracking of beetle species recorded from GSMNP. If you are identifying
beetles for the ATBI, please check your determinations against this list and
provide us with the names of any new taxa that should be added.
Products
Collections of Coleoptera at the GSMNP will be enhanced, with an ultimate
goal of having all species present in the park represented in the GSMNP insect
collection. A database of the Coleoptera of GSMNP will be generated (at least 3500 species of beetles can be expected) as part of the larger ATBI effort.
The Coleoptera twig will provide important taxonomic and biological information
for the GSMNP by expediting and coordinating identifications of beetles and
documenting their distributions within its boundaries.
