Groups of closely related types within a geologic district 

 with recurring patterns of landforms, soil, and vegetation. 



Group of neighboring phases within a land type association 

 with similar soil series or families with similar plant commu- 

 nities at the level of Daubermiire's (1968) habitat types (e.g., 

 valley bottom). 



Group of neighboring sites within land types having similar 

 soil properties with closely related habitat types. 



Repeating units within valley bottom classes that are made 

 up of distinctive groups of riverine and riparian types. 



Repeating types within riverine and riparian complexes 

 dictated by the location and combination of soils and water. 



What's at that final point (i.e., pool, riffle). 



States Are used to describe functional position within a number of 



major site environments for a particular piece of ground 

 fixed in space and the cause/effect relationships that deter- 

 mine its position. 



Ecological Considerations: Daubenmire concepts of succession, climax, ecological site are 

 incorporated at the complex and commimity type level. 



Use, Testing, Validation: The method has undergone testing and is now being applied in a 

 regional scale to northern Nevada. 



Ease of Application: The upper hierarchical data requirements are fairly easy to obtain 

 though the use of existing resource information. The data requirements at the complex and 

 community type level require field data collection similar to that required in most of the 

 Daubenmire procedures. The site information can be as complex as the user wants to make 

 it The procedure would require personnel from several areas of expertise. 



Use in Defining System Response and Potential: System response is a key element and 

 one of the objectives of the procedure. 



Use in Determining State of System: The state of the system is inherent in the procedure. 



^ Riverine and riparian types are two distinct mappable uses, with riverine ecosystems being 

 that within the channel.
