NCCN Fish Inventory for Fort Clatsop National Memorial, NCCN Project FIa09. The NPS established the Natural Resource Inventory and Monitoring Program (I&M) to help park units collect scientifically credible ecological resource information and to develop or improve field and analytical monitoring techniques. As a first step, 5-year inventories were initiated in the North Coast and Cascades Network (NCCN) to gather core sets of data describing park vascular plants and vertebrate resources. A baseline inventory of fish species in two streams within Fort Clatsop National Memorial (FOCL) was conducted to: 1) determine the presence of fish species in each creek; 2) determine general distributions of fish in each creek; 3) establish a voucher collection; and 4) provide recommendations related to fisheries resources in the park. A total of nine fish species were observed in Alder Creek and five fish species in Hansen Creek. The abundance of each species was relatively low throughout each stream. Generally, there is limited spawning and rearing habitat throughout FOCL. It is likely that we did not capture the entire fish species assemblage in FOCL based on the limited sampling effort (spatially and temporally), the extent of seasonal movements of fish, and the presumed high occurrence of non-native fish species in the lower Columbia Basin.
