•
During the field season of 1966 (the third of a five-year program) additional
data were gathered to determine trends in and speed of change in the vegetation
of Teton County. Particular attention has been given to the aspen stands along
the lower banks of Pacific Creek. Some information gathered during the past
season has been released as Wyoming Range Management Issue No. 233, and article
entitled "A 1966 survey of summer elk ranges in southern Yellowstone".

Sedum of North America, North of the Mexican Plateau
Robert T. Clausen
Cornell University
Project Number 142
The Research Station was used as a base while working in the Teton Mountains
and the adjacent Pinyon Peak Highlands in July and August. Studies were concerned
with the classification, distribution and evolution of species of Sedum, the genus
of stonecrops. Detailed studies of populations, as part of a sampling survey, and
collections of living plants for experimental investigations at Ithaca were made.
The small laboratory at the Station made possible the temporary culture of plants
there, until they could be either shipped or taken back to Ithaca. Also, the
program at the Station included preliminary microscopic examination of the gross
morphology, especially of the floral parts. The work on Sedum in 1966 is part of
a comprehensive study of the whole genus. Results of the research in Wyoming are
being incorporated in the manuscript of a book on the North American species.
