The beautiful flute-like call of the wood thrush, the unmistakable gobble of the male wild turkey. Lovely clandestine wild orchids, threatened by incursions of invasive plants such as Japanese grass, privet, and kudzu. These and many others were the animals and plants heard about by those attending the annual meeting of Advocates for the Oak Ridge Reservation (AFORR) on Tuesday evening, June 13, 2000, in the Oak Ridge Mall Community Room. The almost 50 attendees -- including Democratic Congressional candidate Will Callaway of Chattanooga and Linda Ponce, manager of Congressman Zach Wamp's Oak Ridge office -- listened to Drs. Dev Joslin and Larry Pounds discuss birds and plants on the Oak Ridge Reservation (ORR).
Joslin's well-documented
message was that the ORR provides habitat for numerous bird species, many
of which are in decline regionally or nationally, including several
that are not otherwise common in the area. For example, of the almost 200
bird species found on the ORR (more than on any other single tract in East
Tennessee), 28 species are considered "of conservation concern" by international
organizations. Fourteen of those migratory songbird species of concern
are among the 40 most common birds on
the ORR. Familiar
examples include wood thrush, scarlet tanager, bobwhite quail, and yellow-billed
cuckoo, plus 17 species of warblers. In contrast, the bird species most
frequently found in surveys in nearby Knox County are common and widespread
urban/suburban/agricultural species such as European starling, common grackle,
and American crow.
The ORR's abundance and diversity of bird species, Joslin noted, is largely a result of the large areas of unfragmented forest and other specialized habitats present. These large forest expanses provide protection from predators (including house cats), from nest parasitizing cowbirds, and from aggressive non-native birds that compete for nest sites.
Surprisingly to many, perhaps, Joslin said that early successional "old field" habitats, created in part by devastations of pine stands by the southern pine beetle, are uncommon in the region and provide habitat for some declining bird species, such as prairie warbler and yellow-breasted chat.
Dr. Larry Pounds
focussed on the problems of exotic (non-native) invasive plant species
on the ORR and in the surrounding region. Pounds noted that these invasive
species occur far less frequently on the ORR than in surrounding areas,
largely due to the relatively unfragmented, undeveloped nature of the ORR.
Nonetheless, incursions of privet, kudzu, Nepal grass, and non-native honeysuckle
are important in designing management strategies to conserve native plants
for research, education, and recreation.
Accordingly, there
are many opportunities on the ORR for further research and for management
actions concerning invasion by non-native plants and conservation of native
plants, communities, and habitats.
In the business
portion of the meeting, Ellen Smith reviewed AFORR's activities and events
over the past year. Highlights included participating in a forum on the
future of the ORR; holding a public meeting on the proposed ED-3 lease;
making comments on the future of the Boeing property; attending meetings
with public officials; and writing letters relating to the future of the
ORR.
Following the presentations by Joslin and Pounds, a lively discussion ensued regarding future goals and actions. Strategic initiatives proposed and discussed were as follows:
