Nature Walks 2021

All Nature Walks are cancelled due to COVID-19 until further notice. Check back for further updates. 

On the Oak Ridge Reservation, located in east Tennessee, over 1100 vascular plants, 72 fish, 34 mammals and over 200 bird species have been observed.  Nature walks are designed to highlight not only the rich flora and fauna diversity of the reservation, but also to demonstrate the work being done to sustainably manage and conserve this resource. Walks take place on several locations across the Oak Ridge Reservation beginning in late winter through mid-summer.

Reservations for the following events must be made in advance by noon the Thursday prior to each walk by contacting Tracy Clem, 865-574-5151 or If inclement weather forces postponement of an event, it will be announced on ORNL’s Information Line at 865-574-9836 (i.e. 574-XTEN) at least two hours before the scheduled start of the walk.
