|Welcome to Tigrett WMA.|
Three miles south of Dyersburg, along the North Fork Forked Deer River
and the Middle Fork Forked Deer River, in the counties of Crockett, Dyer and Gibson,
Physiographic Province: PIF 04 (East Gulf Coastal Plain); BCR 27 (Southeastern Coastal Plain)
Tigrett Wildlife Management Area--Lat. 355900N Long. 0891730W
Elevation Range: 265' - 278'
266' Tigrett Wildlife Management Area
Size: 7,595 acres
USGS 7.5' quad: Bonicord
Description: Approximately 60% (4,457 acres) of the site is ponded swamp, shrub, and scrub type wetland habitat. Because of the channelization levees that keeps water ponded 12 months a year, approximately 4,000 acres will have water on it most of the year. Some 6.6 miles of the North Fork Forked Deer River and 3.51 miles of the Middle Fork of the Forked Deer River transverse the management area. In addition, there are 6.6 miles of old North Fork River meanders and 2.64 miles of old Middle Fork River meanders in the management area. These meanders are included in the 4,000 acres of ponded swamp. There are small areas of quality bottomland hardwood scattered throughout.
Ornithological Importance: Species associated with ponded swamp wetland habitat highlight this site. Mississippi Kite, a Tennessee In Need of Management species, averages 20 individuals and a maximum of 50 individuals using the site during the breeding season (1993-2004). No nest has been found . Bald Eagle, a Tennessee In Need of Management species, averages 4 birds and a maximum of 8 birds during the winter (1993-2004). In spring 2005, one pair of eagles nested on the site. Shorebirds occur in small numbers.
Point Counts: Thirty-seven point counts were conducted in 1995, 16 in 1996, 39 in 1997, and 21 in 1998. In 113 counts over 4 years, 2,127 birds of 65 species were observed. The table below summaries the top 20 species on point counts at the Tigrett Wildlife Management Area by relative abundance of individuals in the period 1997-2000. Of the top 20 species, 6 species (30%) were neotropical. The Prothonotary Warbler was the most common neotropical. The East Gulf Coastal Plain is a center of abundance for this species.

Note 1. Waterfowl numbers in the "Tennessee Mid-Winter Waterfowl Survey," do not reflect the degree of waterfowl usage of the area since the birds are hunted and are not present during the daytime aerial survey period. The large numbers are present generally after the close of the hunting season and no additional survey data is available.
Note 2. Wading birds present during the migration periods include Great Blue Heron, Great Egret, Snowy Egret, Little Blue Heron, Tricolored Heron (few), and Green Heron. No numbers as to species are recorded.

Critical concerns are water pollution (sedimentation), agricultural
conversion, drainage, and channelization. Serious concern is
deforestation. Potential concern is pesticides.
Management Program: None.
