Three proposed Log Transfer Facility LTF sites were investigated in Patterson Bay Figs. 1 2. There was minimal macrophyte development, and epibenthic invertebrates were relatively sparse at all sites. Site 1: Site 1, located about 200 meters north of the old LTF site, is the FWS preferred development site.

Summary
Description
This years brood count very likely gives a more thorough inventory of lake production than do the last two years counts: whereas most lakes were spot surveyed from shore in 1983 and 1984, almost all lake shorelines were completely canoed in 1985. On all the lakes inventoried, duck production was significantly higher in 19BS .61 youngacre on 71 lakes than in 1984 .37 youngacre on 9 lakes. However, a direct comparison of the 11 lakes which were surveyed in both years shows that duck production did not increase .44 youngacre in both years, and in view of the more thorough survey method this year, actual production probably decreased. Goose production on lakes also appears to have dropped in 1985; but it should be noted that young geese escape on land more readily than young ducks, so 1984s spot surveys may not have spooked as many goose broods as this years canoe surveys. Both duck and goose production on the Kanuti River were lower this year than last. The survey method was essentially the same in both years. Whitefronted Goose production fell drastically from.05 youngacre in 1984 to.01 youngacre in 1985.

Description
The survey visited all active fish camps to determine numbers of fish caught and methods of capture and preservation. Major streams were surveyed to determine escapement numbers and location of spawning areas. Chum salmon, Oncorhynchus keta, were found to be the most important species in the fishery. Silver salmon, Oncorhynchus kisutch, said to be the most abundant salmon, are not heavily utilized.

Summary
Description
Several understory communities display successional stages during the first 200 years after logging or fire disturbance in the Coastal PiceaTsuga forests of southeast Alaska. Residual shrubs and tree seedlings increase their growth exponentially after overstory removal. Understory biomass peaks about 15 to 25 years after logging. Vascular plants are virtually eliminated from the understory after forest canopies close at stand ages of 25 to 35 years. Bryophytes and ferns dominate understory biomass during the following century. An understory of deciduous shrubs and herbs is reestablished after 140 to 160years. Thereafter, biomass of the vascular understory continues to increase, while bryophyte biomass and tree productivity decline. Departures from this developmental sequence are related to unusual types of stand establishment, soil, microclimate, or disturbance.

Summary
Description
We found 16 nests during 1988 with an additional brood being observed in late July. Mean clutch size for 1988 was 4.6 eggs per nest found. We attempted to capture adults at 15 nest sites. We captured 28 or 93 percent of the 30 adults. A total of 63 nestlings were banded from 527 July. Radiotelemetry data were collected for a total of 25.5 hours over 9 days from 11 to 30 July. We continued to experience phenomenal success capturing adults using a great horned owl as a lure. We were concerned that adults experienced with this trapping technique would be less likely to be retrapped than inexperienced birds, but it appears that prior captures do not influence the likelihood that a merlin will be caught again.

Observations of translocated Aleutian Canada geese following their release at Nizki/Alaid Island in August 1990
Published By US Fish and Wildlife Service, Department of the Interior
Issued over 9 years ago
Summary
Description
Using available information, we estimate that 19 of the 20 birds in the first translocated flock were still alive 2 days after their release, and at least 8 birds from the second flock were alive 2 days after their release. On 2 different occasions, a banded gosling was seen in a large flock of geese, at least some of which were not among the translocated birds. Therefore, we can conclude that some of the translocated geese were mingling with the resident birds. We is recommend that Mallard Pond continue to be used as a release site on Nizki because the area immediately surrounding the pond provides good shelter and foraging habitat for geese and because of its proximity to Mallard Cove, which provides excellent boat access.

Summary
Description
Nesting success was high in 1990, and moderate numbers of subadult birds, which may nest in future years, were present. Furthermore, a translocation of 38 geese from Buldir Island in August supplemented the 1990 production at NizkiAlaid Byrd and Mayock 1990.The program to reestablish Aleutian Canada geese at NizkiAlaid is off to a good start. Nevertheless, this small nucleus from which a selfsustaining population must ultimately develop needs to be carefully watched and supplemented until it reaches a level 2025 pairs which would be relatively safe from extinction due to random processes.
