During the 20th century loblolly pines came to dominate much of the park ecology. Beloved by visitors, this pine forest was ultimately unsustainable. A protracted draught and subsequent hurricanes led to widespread tree mortality throughout the park by This photo from the ecological study by Marguerite Key Fitzgerald shows open areas of grass and loose motts of trees similar to pine, hardwood savannah, a native regional ecology.

Backward walking is used increasingly in rehabilitation programs to promote balance, strength, and aerobic conditioning. This study examines the effect of movement direction on the temporal—spatial gait characteristics of old versus young adults when progressing at a comfortable pace and as fast as possible. Participants included 40 old mean age Using a computer-based walkway system, participants were requested to walk forward and backward at a normal pace and as fast as possible. Analyses of variance and Tukey—Kramer tests were conducted to determine effects of age, movement direction, and acceleration of gait speed on various gait parameters. Forward and backward walking of elderly persons is generally characterized by a lower velocity, cadence, stride length, and swing phase, accompanied by an increase in the double-support phase.
