Assessing Bash Risk Potential of Migrating and Breeding Osprey in the Mid-Atlantic Chesapeake Bay Region

Osprey (Pandion haliaetus) pose a significant risk to safe military flight operations. A multi-agency research project was initiated to quantify the risk of osprey-military aircraft collisions in the Mid-Atlantic Chesapeake Bay Region. During the 2006 nesting season, six adult osprey (three males and three females) were fitted with satellite transmitters near Langley Air Force Base, Virginia. We monitored satellite-tagged osprey movement patterns and obtained the location of each osprey at two-hour intervals during 0500-2300 hours during the breeding and fall migration periods of 2006....


Eradicating Tall Fescue Using Glyphosate followed by Cool-season Grass Seedings

Tall fescue (Festuca arundinacea) grasslands do not provide quality habitat for northern bobwhite quail (Colinus virginianus). Converting tall fescue fields to other cool-season grasses and legumes (CSG) may provide more favorable wildlife habitat. We evaluated the effectiveness of spring and fall pre-emergence Round-Up PRO” applications with and without prescribed burns for eradicating tall fescue and establishing CSGs. Two tall fescue fields were located in western Kentucky. Prescribed burns, herbicide applications, and CSG seedings were applied in 2 0.05-ha treatment plots during spring...
