Park-assigned Study Id. # CRLA1991AACV
Permit Expiration Date: Jan 01, 1998
Permit Start Date: Jan 01, 1998
Study Starting Date: Jan 01, 2001
Study Ending Date: Jan 01, 2001
Study Status: Completed
Activity Type: Other
Subject/Discipline: Birds / Ornithology
Objectives: Inventory park lands for individuals and pairs of spotted owl (strix occidentallis). Identified pairs will be banded and locations will be recorded. This information will be used in comparison with pairs in non-stable environments on surrounding national forests.
Findings and Status: Two nesting pairs of spotted owls and two other separate individuals, one of the pairs produced two offspring.
For this study, were one or more specimens collected and removed from the park but not destroyed during analyses? No
