predicting daily peak visitation and implication for recreation
management and water quality: evidence from two rivers in Puerto
Rico”. Environ. Manage., 41: 904-914.
Abstract:
Visitor use surveys and water quality data
indicates that high visitor use levels of two rivers in Puerto
Rico does not appear to adversely affect several water
quality parameters. Optimum visitor use to maximize visitor
defined satisfaction is a more constraining limit on
visitor use than water quality. Our multiple regression
analysis suggests that visitor use of about 150 visitors per
day yields the highest level of visitor reported satisfaction,
a level that does not appear to affect turbidity of the river.
This high level of visitor use may be related to the gregarious
nature of Puerto Ricans and their tolerance for
crowding on this densely populated island. The daily peak
visitation model indicates that regulating the number of
parking spaces may be the most effective way to keep
visitor use within the social carrying capacity.
