36 FISH AND GA^klE COMMISSION 



artificial roosts are being tested. Also, the effects of cover removal, grazing, cultivation, 

 controlled burning, rodent control, predator control, and hunting pressure on quail 

 populations are being investigated. This project is under the leadership of Wallace 

 G. Macgregor. 



Project 35-R, A Study of Diseases of Wildlife Species in California, is concerned 

 especially with those diseases which are of deiinite 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 13-D, 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 quail, and includes plantings for food and cover improvement, the erect- 

 ing of artificial quail roosts, and the construction of "gallinaceous guzzlers" or rain 

 catchment basins for providing quail with water. Through this habitat development 

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

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

 from county fine moneys, and physical labor from sportsmen and other interested 

 groups. 



The "gallinaceous guzzler" program has been accelerated by the use of prefabri- 

 cated plastic 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 moved to a new site, if the original location proves unsatis- 

 factory. 



During the biennium 574 guzzlers were installed, bringing to 734 the number 

 now in operation. 



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

 habitat, to extend the range of a species, and to supplement remnant species. The work 

 consisted of live-trapping and transplanting game mammals where required. The 

 project operated periodically only when the need for this type of work arose. 



Project 30-D, Development of Imperial Waterfowl Management Area, involving 

 12.W) acres of land, provided waterfowl feeding, resting, public shooting areas and 

 facilities for the proper management of the area by the construction of levees, ditches 

 and buildings, and by the development of the land for farming of waterfowl food crops. 



Project 38-D, Development of the Honey Lake Waterfowl Management Area, 

 involves 3,520 acres of land for the provision of waterfowl feeding, resting and nest- 

 ing areas and facilities for the proper management of the area by construction of 

 levees, ditches, roads and buildings. 



Project 39-D, Development of the Madeline Plains Waterfowl Management 

 Area, involving 4,776 acres of land, provided waterfowl feeding, resting and nesting 

 areas and facilities for the proper management of the area by construction of levees, 

 ditches, roads and buildings. 



LAND ACQUISITION 



Project lO-L, Tehama Winter Deer Range. This area provides winter feed for 

 deer migrating down from the mountains. To preserve this winter range 33,963 acres 

 have been acquired, and more land may be purchased if it becomes available. 



Project ] ] -L, Honey Lake Waterfowl Management Area. An area of 3,520 acres 

 ha.x been purchased for waterfowl feeding, resting, nesting, and to provide public 

 shooting areas. Additional segments of land will be purchased as they become available. 



Project 17-L, Madeline Plains Waterfowl Management Area. To provide water- 

 fowl with feeding, resting and nesting areas and to furnish the public with hunting 

 Krounds. 5.176 arr.'s of land have boon purchased. More land Avill be acquired as it 

 bocwmos aviiijabjo. 



Project 21 -L. Doyle Winter Deer Range. An area of 11,700 acres of land has 

 Wph purchfisod to r.rovide winter feed for the migrating interstate deer herd. Further 

 purchases will be made as the land becomes available.
