REASONS FOR CURRENT STATUS 



This lizard has become increasingly difficult 

 to find throughout most of its range because of 

 agricultural development and urbanization. The 

 few remaining areas of prime habitat, along the 

 western side of the San Joaquin Valley, are under- 

 going rapid development following the recent 

 completion of a major new aqueduct (the Califor- 

 nia Aqueduct) (Erode 1978, Bury 1972, Monta- 

 nucci 1965, Snow 1972, U.S. Dep. Int. 1973). 

 Off-road vehicle recreation is damaging the re- 

 maining habitat in some nonagricultural areas 

 (Erode 1978). Overgrazing and agricultural pest 

 control may be detrimental to C. (G.) silus popu- 

 lations (Anon 1978).
