Report Number: 12792

Permit Number: CRLA1996AOZM

Date Received: Jan 01, 1998

Reporting Year: 1996

Principal Investigator: Elizabeth Horn, Missoula, MT

Park-assigned Study Id. # CRLA1996AOZM

Permit Expiration Date: Jan 01, 1998

Permit Start Date: Jan 01, 1998

Study Starting Date: Jan 01, 1996

Study Ending Date: Jan 01, 1996

Study Status: Completed

Activity Type: Inventory

Subject/Discipline: Ecology (Aquatic, Marine, Terrestrial)

Objectives: Study the ecology of the Pumice Desert to learn more about the lack of succession.

Findings and Status: Preliminary findings from the vegetation plots examined during the summer of 1995 indicate fewer plant numbers; this is probably due more to the recent years of drought in the Northwest than any indication of successional stages. Comparison of photo points (1965, 1995) whowed that many of the trees in the 1965 photos had died; causes were not determined.

For this study, were one or more specimens collected and removed from the park but not destroyed during analyses? No
