The
Institute for Bird Populations
(IBP) is dedicated to fostering a global approach to research and the
dissemination of information on changes in the abundance, distribution,
and ecology of bird populations. Since 1994, IBP has partnered with
DoD land managers to a) monitor landbird populations, b) model demographic
estimates as functions of landscape pattern and change, c) model demographic
estimates as functions of weather and climate, d) provide management
guidelines to maintain source habitat for species of concern, and e)
monitor the efficacy of management. Funding for these activities has
been provided by the Legacy Resurces Management Office, US Army Corps
of Engineers, and Naval Facilities Engineering Command, Atlantic Division.
IBP's activities
at NIOC Sugar Grove have included:
a) Demographic Monitoring of Bird Populations
(2007
Report, 2008 Report)
- IBP has operated four Monitoring Avian Productivity and Survivorship
(MAPS) stations: one on the lower base, one on the uppper base, and
two on neighboring USDA Forest Service's George Washington NF. We provide
annual MAPS reports and maintain a bird checklist for distribution among
base personnel and their families. The MAPS data monitor the health
of the bird populations, especially Neotropical migrants such as Worm-eating
Warbler (Helmitheros vermivorus) and contribute to regional
(i.e., Appalachian) and continental MAPS datasets and in the future
the Avian Knowledge Network administered by Cornell Lab of Ornithology.
b) Biological Assessment of Shale Barren Habitat
(PDF)
- Dr. Phil Nott reviewed the status of Shale Barren
Rock Cress and other species endemic to the rare shale barren habitats
of the Appalachians, including the Little Fork shale barren that lies
within the stewardship of NIOC Sugar Grove. Since the mid to late 1980’s
two species of butterfly, the Grizzled Skipper (Pyrgus Wyandot)
and Olympia Marble (Euchloe olympia), have been extirpated
from many shale barrens, including the Little Fork. The report, submitted
to West Virginia Division of Natural Resources, concluded that these
two species should be reintroduced to the barrens, and that the use
of pesticides to control Gypsy Moth eruptions should not be permitted
in the vicinity of shale barrens.
c) Butterfly Reintroduction Project
(2008
Report)- At the end of April 2008, Dr. Phil Nott visited NIOC Sugar
Grove and surveyed the locations of three historical Grizzled Skipper
populations. Olympia Marble had also been recorded at these locations.
Further visits during the summer to these locations and other historical
locations throughout West Virginia by MAPS interns revealed no flying
adults or pupae of either species. However, evidence of Grizzled Skipper
larval activity was found on Canada Cinquefoil plants located on a privately-owned
shale barren. These findings have been reported to Virginia DNR and
NIOC Sugar Grove.
d) Butterfly Transect Monitoring -
Two butterfly transects were established in 2007 and monitored in 2007
and 2008. We intend to analyze butterfly transect data after three years
of collection. However, these transects and area searches
have led to the development and maintenance of a butterfly checklist
for NIOC Sugar Grove Web-based
NIOC Sugar Grove Butterfly Checklist.
