Appendix 1-6 



a WETLANDS THREATS 



For the purpose of the National Wetlands Priority Conservation Plan, 

 threat is defined as the likelihood that a wetland site, or portion thereof, 

 will be destroyed or degraded, directly or indirectly, through human 

 actions. 



In establishing the threat threshold, a wetland site is considered to be 

 threatened if an estimated > 10 percent of the site's wetland functions and 

 values are likely to be destroyed or adversely affected through direct, 

 indirect, or cumulative impacts over the next ten years considering: 



1. the array of potential wetland threats; and 



2. the probable degree of protection provided by the various relevant 

 laws, ordinances and regulations. 



At a minimum, the following items should be considered when evaluating 

 wetland threat (indicate activities that either destroy or degrade wetlands 

 at the site): 



a. Drainage or filling 



b. Agricultural conversion or use 



c. Livestock grazing 



d. Groundwater withdrawal/depletion 



e. Loss of instream flows 



f. Residential or commercial development 



g. Oil, gas, mineral development 



h. Power plants 



i . Transportation (roads and bridges) 



j . Navigation project, port, marina or pier 



k . Water development project(s) 



1. Water pollution 



m . Other, (e.g., timber or vegetation removal, mosquito 



control practices, diverse ownership with no individual 

 commitment to protection): 



Indicate all laws, ordinances or programs that have some degree of 

 wetland protection potential for this site: 



a. Clean Water Act (Corps section 404 regulatory program) 



b. River and Harbor Act (Corps section 10 regulatory 



program) 



c. Endangered Species Act 



d . Water Resources Development Act of 1986 



e. Food Security Act of 1985 



f . Local zoning or ordinances (e.g., local wetland or 



floodplain zoning)
