SITE DESCRIPTIONS 



The sites of the community types are described below using tables and 

 short discussions.

Scam c.t. sites are similar to the Dist c.t. sites but are much moister. 

 Tests run on two soil samples from this type gave average electrical conductivity 

 values in excess of 10-3 mhos/cm and an average sodium-absorption ration of 52. 

 Some soil properties of selected communities are given in table 3. Grazing pres- 

 sure is hard to determine because of trampling caused by proximity to water; 

 utilization is low.
