Table 17. Muhlenbergia cuspidata - Agropyron spicatum Community Type Site Description 



SOIL texture: 



10» sandy loams; 50X loams; 30" silt loams; IQ'i clay loams 



SLOPE-SLOPE ASPECT 



Mean : 



Standard deviation: 



Range: 



Sites having: 



Positive slope-slope aspect values: 

 Slope-slope aspect values of 0: 



The site descriptions for the Agsp-Mucu c.t. and those for the Agsp/Bogr- 

 Cafi c.t. do not point to any conclusive difference. These two sites for the 

 two types differ most noticeably in their slope-slope aspect values, but these 

 do not differ significantly if the atypical value is dropped from the Agsp/Bogr- 

 Cafi c.t. site data, and only at the 0.5 probability level if all the data are 

 used. Perhaps the best explanation is that substrates for this type are more 

 gravelly than Agsp/Bogr-Caf i c.t. substrates.
