“…This research was undertaken in April, 1971, under Laboratories, Prime AEC contract AT(26-1)-171. The 1967The -1971 studies under the latter contract allowed an assessment of the Amchitka vegetation and characterizations of the ecological processes controlling or influencing the composition, structure, and productivity of the vegetation. This part of the study has been suspended since 1974.…”

“…The Amchitka work has resulted in one comprehensive report (Amundsen, 1972), a published summarization (Amundsen and Clebsch, 1971), a cooperative assessment of the effects of nuclear tests on the geomorphology and plant ecology of Amchitka (Everett and Amundsen, 1975) and a compilation of ecological material from the botanical point of view in a chapter for inclusion in a forthcoming volume on the Amchitka bioenvironment (chapter manuscript. May 1976, now at the printer for publication).…”

A study, begun in 1971, continues to document the environmental factors which affect the recovery of damaged tundra landscapes. A measurement technique was developed on Amchitka Island to allow the rapid acquisition of data on species presence and frequency across areas disturbed at various times and in various ways. Samples across all examples of aspect, slope steepness and exposure are taken. Studies now include Adak Island and the Point Barrow area. We have concluded that there was no directional secondary succession on the Aleutian tundra, although there was vigorous recovery on organic soils. Our study led to recommendations which resulted in less intensive reclamation management at a considerable financial saving and without further biological perturbation. Because of the increasing activity on tundra landscapes, for energy extraction, transportation or production; military or other reasons, we have expanded our sampling to other tundra areas where landscape disruption is occurring, or is predicted.

“…Natural recovery of the maritime tundra in disturbed areas of the Aleutians is very slow (Amundsen and Clebsch, 1971;Amundsen, 1977;Williams, 1980). Disturbances from the 1940's through the present may be easily noted on the landscape and dated from construction reports.…”
