–Repr. in J.M. Packard (1983c: 125-132). Describes manatees' use of Crystal River as a warm-water winter refugium, based on aerial and boat surveys, 1967-78; the sex and age composition of the population; the number of known individuals resighted in successive winters; and the calving intervals of known females. Age at first conception is estimated at 7-8 years, calving interval at either 2.5 or 5 years.
