The objectives of the San Juan Ecology Project remain
unchanged, namely to determine the effect of increased
snowfall on the major biotic and related physical
ecosystem components of the San Juan Mountains target
area, with emphasis on those components which are of
economic and/or public interest to man. Because of
the large variation in the annual snowfall of the area,
and the relatively small anticipated increase as a
result of seeding, the effects of snow variation,
rather than those of snow increases, are being inves-
tigated here.

The project ~s organized under two main groups, a
Forest Ecosystems Team and an Alpine Tundra Ecosystem
Team. Colorado State University and Fort Lewis College
combine in the former, while the University of
Colorado, through its Institute of Artie and Alpine
Research, is responsible for the latter.

During the reporting period, overall administration
of the project was conducted through the Project
Coordinator (Dr. H. Leo Teller, Colorado State Univer-
sity) and the two Team Leaders: Forest Ecosystems -
Dr. Harold W,. Steinhoff, Colorado State University;
Alpine Tundra Ecosystems - Dr. ,Jack D. Ives, Univer-
sity of Colorado.

Major decisions concerning the whole project were made
by a Steering Committee, which included the Project
Coordinator as Chairman, the two team leaders, and
three other members; Dr. Herbert E. Owen, Fort Lewis
College; Dr. C. Patrick Reid, Colorado State Univ-
ersity; and Dr. Patrick J. Webber, University of
Colorado. Mr. R. Carl James, as Project Monitor,
provided 1isison between the Project and the Bureau
of Reclamation.

Liaison was ~intained with the Medicine Bow (Univer-
sity of Wyoming) and the Montana State University
weather modification ecology teams, and with various
agencies, such as the Forest Service and the National
Center for Atmospheric Research, which are also con-
cerned with weather modification effects.

The fourth annual SJEP Technical Conference was held
on November 29, 1973 at the University of Colorado.
In addition,; each of the Teams hold regular seminars
through the year, where principal investigators and
graduate res,earch assistants discuss current develop-
ments in the'ir work and consider problems of general
interest. During the 1973 summer, exchange visits of
project personnel and university administrators were
made to intensive sites in both ecosystems.

Dr. H. Leo Teller took special leave from CSU for an
assignment with UNESCO, Paris, so he resigned as
Coordinator on July 1, 1974. Dr. Harold W. Steinhoff
was named Coordinator and was responsible for compil-
ation and publication of this report.
