Oak Ridge Reservation Physical Characteristics and Natural Resources

Stream discharge and water quality data for East Fork Poplar Creek beginning 2012

“…Additionally, these high-frequency data sets, started in 2012, can be used by the broader scientific community to evaluate fundamental biogeochemical processes and hydrologic relationships in an urban/industrially impacted watershed. local evapotranspiration has been estimated at 74-76 cm (Parr & Hughes, 2006). Streamflow exhibits strong seasonality due to high evapotranspiration from late March to mid-October (Mulholland et al, 1997).…”

Oak Ridge Reservation Bird Records and Population Trends

“…Kroodsma (1984aKroodsma ( , 1984b recorded northern bobwhite along power-line edges on the ORR in the mid to late 1970s. The most common areas noted for this species during PIF surveys have been at Dyllis Orchard/Raby Road (1996-2003, 2005, 2007-08), Freels Bend (1996-2001, 2003, 2006, 2011 and Poplar Creek (1996-2000, 2002-03, 2008. A recent grassland bird survey noted no northern bobwhites in exotic grass fields and only low numbers in early successional and mid-successional cover types (Brinkley and Buehler 2012).…”

“…Five cerulean warblers were observed in the Walker Branch Watershed in April 1996, and two additional observations of this species were recorded that same month in a 3-to 5-year old regenerating clearcut loblolly stand near the Poplar Creek floodplain (Mitchell et al 1996;Mann et al 1997). Recent PIF survey records include New Zion Patrol Road (1999), Poplar Creek (2001, 2004) and Gallaher Bend (2005, 2006, 2009. The most recent eBird records are for April 10, 2013, at Freels Bend and May 25, 2013, at the North Boundary Greenway Trail.…”

“…ORR forests are mostly oak-hickory, pine-hardwood, or pine. Minor areas of other hardwood forest cover types are found throughout the Reservation, including northern hardwoods, a few small natural stands of hemlock or white pine, and floodplain forests (Parr and Hughes 2006) (Fig. 2).…”
