Bridging the Gap Between Seafood and Forest Management

This Friday marks the beginning of a well-loved Sitka tradition, the Alaska Seafood Festival! The festival began in 2010, as a way to celebrate the bountiful ocean resources Sitka and Southeast Alaska has to offer. The fishing industry supplies significant revenue and jobs for the community as well as attracting tourists. Because seafood is such an important part of the Sitka community, it is essential that the resource is not only celebrated at the festival but also considered beyond the city limits.

Most Sitka residents and visitors enjoy the benefits of having plentiful wilderness recreation sites just a short distance from the city. These recreation sites are often within the Tongass National Forest. Like all national forests, the Tongass is under management of the US Forest Service. Over the past few weeks I’ve had the opportunity to work with Sitka Conservation Society (SCS) and the Forest Service to evaluate different forest treatment plans created to ensure the forest, streams, and salmon are all working together in harmony. One concern is ample habitat for rearing juvenile and spawning adult salmon. Salmon depend on wood in the streams to create sheltered areas with a reduced current. However, past harvesting in the Tongass has disrupted the conifer growth that supplies this habitat. The good news is that the Forest Service has been applying different forest treatment plans to different areas with the goal of growing larger conifers that will eventually fall into the stream to provide habitat. Plentiful habitat then ensures thriving salmon populations that will prosper in the future.

One such area is Appleton Cove located on North Baranof Island. SCS and the Forest Service recently traveled to this area to observe how trees along stream banks are growing and what kinds of trees there are. Our studies consisted of setting up four to six plots along the stream bank and flagging every live tree within these plots. We then recorded the tree species, diameter, and height. This study was also done at Fish Bay, Noxon, and other sites in order to create a representative and diverse sample. These studies will be combined with developing Forest Service research to guide how the trees along stream banks will be managed through treatments such as thinning.

Another Forest Service Project dedicated to preserving salmon populations is present at Redoubt Lake. Redoubt Lake is one of the largest meromictic lakes in North America meaning the lake has areas of salt water and fresh water that do not mix. Each year thousands of salmon swim from the ocean and up the falls to reach Redoubt Lake to spawn. The Forest Service has set up a weir at the opening of the lake, which is essentially a gate preventing fish from passing except in specific areas. Forest Service workers are then able to count the fish and identify their species as they swim through the weir or past a camera in the evenings. Sockeye and Coho salmon are also sampled meaning they are weighed, measured, and have a scale taken. This information is then used to further study the fish at Redoubt and their genetic make up. One concern is that farmed fish could be mating with wild fish and disrupting wild type DNA. The scale sample comes into play here as it is analyzed by geneticists to determine if the fish has any DNA inherited by a farmed fish. Counting the fish that return to Redoubt Lake each year will also help the Alaska Department of Fish and Game set appropriate harvest limits to ensure future abundance.

This weekend while enjoying festival events such as cooking and canning classes, the seafood banquet, film screenings, and more remember to also consider the connection between forest management and the sustainability of valuable Alaskan seafood.
