Population status of California sea otters

Technical Report · Wed Nov 30 00:00:00 EST 1988

OSTI ID:5729664

The main objective of the study was to develop a simulation model to facilitate analysis of the risk of oil spills to the threatened California sea otter population. Existing data on the dynamics and demography of the population were synthesized. The additional data needed for model development were collected through radiotelemetry studies of sea otters in Alaska and California. The simulation model contains four interrelated stochastic submodels: a short-term population model, a long-term population model, a sea otter distribution model, and a sea otter movement model. The report includes a detailed description of the model, the data on which it is based, and an operating manual.
