You may have noticed purple “boxes” hanging in area trees lately. These are three-sided insect traps for monitoring the spread of a non-native invasive insect that has killed several million ash trees in the eastern United States and Canada.

"The first documented bald eagle nest for the Oak Ridge Reservation was discovered in April 2011. There were two young fledged out of the nest in 2011 and the nest is once again active this year. One young bird has been observed in the nest this year and it appears to be doing well. The North American bald eagle population crashed between the 1950's and mid-1970's, due to an inability to reproduce caused by the effects of the pesticide DDT. It is unknown what the size and distribution of the bald eagle population in Tennessee was prior to the continent-wide decline. There were no known successful bald eagle nests in the state of Tennessee between 1961 and 1983. Efforts to restore the bald eagle population in Tennessee started in 1980 and the first successful post-crash nest in the state was discovered near Cross Creeks National Wildlife Refuge in 1983. Since that time the state population has grown to an estimated 175 nests. Bald eagles are present in the state year-round and they can be fairly routinely seen along the Clinch River and other watercourses adjacent to the Oak Ridge Reservation."

Bird Nesting Boxes
The Oak Ridge Reservation (ORR) provides habitat for over 200 species of birds. Among these are several species dependent on natural or manmade cavities for nesting. Over 120 nest boxes are maintained on the ORR for species like Eastern bluebird, tree swallow, prothonotary warbler, and wood duck. The boxes have been used to mark boundaries of riparian zones and provide watchable wildlife in some areas, among other targeted uses. The nest box program has been very successful and 10 different species have been observed utilizing them as nest sites. New boxes will be added to the ORR as suitable habitat locations are identified.
