1. WETLANDS PROFILE 



Complete items (a) through (g) to give a name and address to each wetland 

 site. 



For the purpose of the National Wetlands Priority Conservation Plan, a 

 wetland site is an identifiable property, tract, area, or region containing 

 wetlands or a complex (aggregation) of physically- or functionally- 

 related wetlands. A wetland site may contain a variety of wetland types, 

 interspersed habitat of other types and associated upland buffer areas. 

 The boundary of the site should be specific and as geographically 

 restricted as practical, determined by application of sound acquisition 

 principles. In other words, regardless of size, a wetland site should be 

 treated in terms of a unit which would generally fit the acquisition goals, 

 process and needs of the user. 



2. WETLAND LOSSES 



Wetlands will be classified as follows: System, subsystem, class and 

 water regime according to Cowardin et al., 1979 (refer to key on next 

 page). Estimate percent of site for each type.
