506 CALIFORNIA FISH AND GAME THE STUDY AREA Gray I^odge State Refuge, where the study was conducted, is an area of approximately 2,500 acres situated in the north-central Sacramento Vallev, 10 miles southwest of the town of Gridlev. The elevation is from 58 to 68 feet above sea level. The refuge has been developed primarily for waterfowl with nearh' 1,800 acres of pond and marshland. It con- tains 22 miles of roads and approximately 18 miles of ditches. Scattered fields of millet, rice, wheat, barley and milo are g-rown, interspersed with edgeland and ungrazed open fields. Pasture lands, cereal crops and private duck clubs adjoin the state property. Most rainfall occurs from October through March, with an average precipitation of 22 inches. ^Maximum summer temperatures often go above 100 degrees F. but winter temperatures seldom fall below 26 degrees F. The principal trees in the area are the white Avillow (Salix sp.) and the Fremont cottonwood (Poj^uhis fremonti). Within the studv area, two small units were closelv observed for in- formation on productivity and general life history of the doves. One of these, the AVillow Pond Area, consisted of approximately two acres of willows surrounding a small pond. This area is shown in Figure 1. The other unit, here called the Headquarters Area, constituted the trees and buildings of the Gray Lodge Refuge Headquarters, an area of approxi- matelv three acres. The term "refuge area" refers to all that area of Gray Lodge Refuge excluding the Willow Pond and Headquarters areas.
