Stream Ecosystem Responses to Forest Leaf Emergence
A paper presenting the results of research on the effects of seasonal reductions in light resulting from emergence of leaves in spring on stream primary and secondary production was recently published in the journal Ecology (see citation in publication section). The paper was based on a study by Walter Hill and Pat Mulholland (Oak Ridge National Laboratory, Environmental Sciences Division) and Erich Marzolf (a former Environmental Sciences Division post-doc) conducted in two Oak Ridge National Environmental Research Park streams, Walker Branch and Upper White Oak Creek. The study showed that stream algal productivity was sharply reduced in May in response to sharp reductions in light levels reaching the streams following leaf emergence in the deciduous forest. In addition, there was a cascading effect of the algal productivity declines up the food chain. Herbivore growth rates declined in synchrony with the reductions in light and algal productivity. This research further highlights the strong effects of forests on the streams that flow through them. It is the latest in a long history of ecosystem research on Oak Ridge Reservation streams.

Native Grass Restoration on the Oak Ridge Reservation
Native grass information prepared by Research Park summer intern, Kari Cohen, is now available on a web site. Check it out at http://www.esd.ornl.gov/facilities/nerp/nativegrass.html. By the way, Kari, a graduate student at the University of Maryland, reports he is fine. He napped right through the tornado which was ripping through the University of Maryland campus about a mile from his apartment.

DOE Land Use Planning Initiative
The first working meeting of the DOE Land Use Planning Focus Group was Friday, September 28. The Land Use Planning Focus Group is reviewing options for uses of federal land that may no longer be required for DOE mission. Town hall-type meetings are also planned throughout the process to gather input from the public. Those dates have not yet been set but will be highlighted here once available.
Environmental Search Engine
Care2.com has launched an environmental search engine for neighborhood eco-reports. The “Care2 Get Local” system provides zip code-based neighborhood reports on over 70 topics, from pollution to hiking trails and organic farms. See http://www.Care2.com.

The Oak Ridge National Environmental Research Park was designated by the Department of Energy in 1980 and is one of a network of seven National Environmental Research Parks. It is an Oak Ridge National Laboratory User Facility. The Oak Ridge National Environmental Research Park was designated an international biosphere reserve in 1989. It is also a unit member of the Southern Appalachian Biosphere Reserve and part of the Southern Appalachian Man and the Biosphere (SAMAB) Cooperative. More information on the Oak Ridge National Environmental Research Park can be found on the website at: http://www.esd.ornl.gov/facilities/nerp/.
