census area for each species. EDD's were defined according to 1) the <br />• distribution of individual observations, or 2) where sample size was <br /> small, the professional judgement of the observer. The density index <br />was calculated as: <br />Birds/100 acres = <br />X observed (3 reps.) _ 43560 sq. ft./acre x 100 <br />2 EDD x Transect Length <br />(both sides of transect) (2625 ft) <br />Relative abundance was calculated as: <br />__ density of a given species <br />~ density of all species x 100 <br />Shannon-Weiner Divezsity indices were calculated according to the <br />general formula given by Poole (1974): <br />s <br />RL = -f Pi log pi <br />? -1 <br />.where s is the number of species and Pi is the proportion of the <br />total number of individuals representing of the Lth species. <br />2.3 Herpetofauna <br />Field biologists were watchfull for herpetofauna activity through- <br />out all elements of field investigation. All opportunistic observations <br />were recorded in field notes. <br /> <br />
