Abstract
The authors analyzed data from Section 404 permits issued in California from January 1971 through November 1987 that involved impacts to wetlands and required compensatory mitigation. The purpose of the study was to determine patterns and trends in permitting activity and to document cumulative effects of associated management decisions on the California wetland resource. The 324 permits examined documented that 387 compensatory wetlands (1255.9 ha) were required as mitigation for impacts to 368 wetlands (1176.3 ha). The utility of the data on wetland area was limited, however, since 38% of the impacted wetlands and 41.6% of the compensatory wetlands lacked acreage data. The number of permits requiring compensatory mitigation and the number of impacted and compensatory wetlands increased from 1971 to 1986. Documentation of the details of Section 404 permit decisions was inadequate for the permits examined.
