OTHER CRITICAL ENVIRONMENTAL 

 REQUIREMENTS 



Little is known about the species beyond 

 its specialized and unique breeding habitat des- 

 cribed above. 



POPULATION NUMBERS AND TRENDS 



No population estimates are reported. 

 Means (1976b) reported that since 1972, two 

 known breeding sites have been rendered un- 

 suitable because of clearing for improved pas- 

 ture. A. J. Bullard (personal communication) 

 reported some North Carolina breeding local- 

 ities also have recently been destroyed. 



Since the discovery of the Pine Barrens tree- 

 frog in Florida (Christman 1970), some 47 

 breeding congregations have been located in 

 three West Florida counties (P. Moler, personal 

 communication). These are all small seepage 

 bogs, and none has been found to contain more 

 than a dozen calling frogs, with most having 

 fewer than four (P. Moler, personal communica- 

 tions). 



REPRODUCTION 



Treefrogs breed from May (April in Florida) 

 to August. Eggs are laid singly on the bo t- 

 tom or attached to sphagnum (Wright and 

 Wright 1949). Eggs hatch in 3 days and may 

 number up to 200 or more per female. Tadpoles 

 transform during the summer and frogs probably 

 reach sexual maturity in 1 year. 



Nothing is known concerning natural longe- 

 vity or survival rates, although a captive survived 

 7 years (A.J. Bullard, personal communication). 



MANAGEMENT AND CONSERVATION 



No management or conservation measures 

 have been instituted other than legal protection 

 against taking, possessing or molesting the spe- 

 cies. The relict, disjunct habitat should be pro- 

 tected from development. 



Many of the known breeding localities in 

 Florida are located within Eglin Air Force Base 

 and Blackwater River State Forest. Means 

 (1976b) suggests purchase of some of the re- 

 maining breeding localities in Florida to prevent 

 habitat destruction. 



Critical Habitat has been designated in 

 Okaloosa County, Florida (42 FR 58754; 11 

 Nov. 77): (1) NW'/4 Sec. 35, T4NR22W; (2) 

 NE'/4 Sec. 27, T4NR22W; (3) SWA Sec. 26, 

 T5NR23W; (4) NWA Sec. 34, T4NR23W; (5) 

 NW'/4 Sec. 32, T4NR22W; (6) NWA Sec. 12, 

 T4NR22W; (7) NE'A Sec. 11, T4NR22W.

PREPARER'S COMMENTS 



The disjunct distribution of the Pine Barrens 

 treefrog makes it of considerable interest from 

 an evolutionary and biogeographic point of 

 view; it is the least known treefrog in the United 

 States. There is a pressing need for basic distri- 

 butional and biological information.
