;irtifit'i;il roosts are being tested. Also, the effects of cover removal, grazing, cnltivation, 

 controlled hnrning. rodent control, predator control, and hunting pressure on (piail 

 I)opulations are being investigated. This project is under the leadership of Wallace 

 C. Macgregor. 



Project 35-R, A Study of Diseases of \\'il(llife Species in California, is concei-ned 

 esijccially with those diseases which are of definite known importance in respect to 

 wildlife, and which appear to offer possibilities of being controlled by management 

 practices. Merton Rosen is leader of this project. 



DEVELOPMENT PROJECTS 



Project 9-D, Suisun Waterfowl Refuge, involves 1887 acres of land to provide 

 waterfowl feeding and resting areas by construction of levees, ditches and tide gates. 



Project l.'M). Gray Lodge Waterfowl Refuge, involves 2,542 acres of land to 

 provide waterfowl feeding and resting areas by construction of levees, ditches, roads 

 and buildings. 



Project 26-D, The Restoration of Valley Quail, Gambel Quail and Mountain 

 Quail in California. This project represents the major effort in habitat development, 

 for California (luail. and includes plantings for food and cover improvement, the erect- 

 ing of artificial (junil roosts, and tlie construction of "gallinaceous guzzlers" or rain 

 catchment basins for i)roviding quail with water. Through this habitat development 

 program, many areas that were formerly unsuitable as quail range are now producing 

 fpiail for California's hunters. The program has received help through financial aid 

 fi-oni county fine moneys, ;ind ])liysical lal)or from sportsmen and other interested 

 groups. 



The "gallinaecous guzzici-" iimgi-ani has ix'cn accelerated by the use of prefabri- 

 cated ])lastic basins and glass mat (asphalt emulsion) catchment aprons. The installa- 

 tion of the plastic model requires about one-fifth the time needed for the construction 

 of the concrete type of guzzler. Another advantage gained by using the plastic model 

 is that it can readily be mo\ed to a new site, if the original location proves unsatis- 

 factory. 



During the biennium r)74 guzzlers were installed, bringing to 734 the number 

 now in operation. 



Project 34-D, Game Trapping .-iiul Transplanting, to restock formerly occupied 

 habitat, to extend the range of a sjx'cies, and to supidemeut remnant sjiecies. The work 

 consisted of live-trai)iiing and traiisiilantiiig game mammals where required. The 

 lu-oject operated iieriodica 1 1.\ (iiil.\ w lien ilir need for this type of work arose.
