The Ansc-Agsp c.t. is found chiefly on scoria and, to a lesser extent, 

 badlands. Although the Ansc-Agsp c.t. might phytosociological ly be inter- 

 preted as being part of a continuum between the Ansc c.t. and the Agsp/Bogr 

 Cafi c.t. and a close relative of the Juho/Ansc-Agsp c.t., it seems to be 

 found on decidedly warmer sites. Slope-slope aspect values are significantly 

 different than Juho/Ansc-Agsp c.t. site values at the 0.05 probability level 

 and different than the Ansc c.t. site values at the 0.2 probability level. 

 Slope-slope aspect values for this type are most similar to Agsp/Bogr-Cafi 

 c.t. site values. There is no significant difference using all data, but a 

 significant difference appears at the 0.1 probability level if one atypical 

 value is dropped from the Agsp/Bogr-Cafi site values.
