DescriptionPressures of urbanization and rapid development continue to increase and recreational activities are becoming a prominent force in many urban wildlife communities. Many urban environments are home to freshwater turtles and little attention has been given to the impact of human recreation upon these communities. We examined the response of basking turtles to observer presence along the towpath of a canal in central New Jersey. All four species, except K. subrubrum, were more frequently observed basking on log substrate and on substrate with less than 50% canopy cover. Along the towpath, 100% of K. subrubrum responded to observer presence by retreating (swimming away), while over 75% of observations on C. picta, T.s. elegans, and P. rubriventris responded to by retreating. There was a highly significant correlation between the distance from the towpath the turtle was first seen basking by the observer and the distance at which the turtle first responded to the observer. Nearly 80% of the variability in distance to first respond to the observer for K. subrubrum was accounted for by including the percent canopy cover, percent cloud cover, and height basking above the water, while less than 30% of the variability was accounted for C. picta, T.s. elegans, and P. rubriventris.
