Abstract
As baleen whales recover from severe exploitation, they are probably subject to a wide variety of
threats within the Antarctic marine ecosystem, including directed take. Here we review both the management
and current status of Antarctic baleen whales and consider those threats likely to impact on them. Threats range
from global problems - marine pollution and climate change - to localized issues including shipping, habitat
disturbance, unregulated wildlife tourism and fishery activities. We identify the most pressing anthropogenic
threats to baleen whales including scientific whaling and climate change. It is unclear whether current
management approaches will be able to effectively encompass all these threats while also accounting both for
the differing levels of scientific understanding and for the differing recovery rates of the whale species. For
management we recommend the following: 1) incorporation of both ecosystem considerations and the suite of
identified threats not limited to direct take, 2) identification of measurable indicators of changes in whales that
allow more certainty in monitoring of populations and the environment, and 3) recognition of significant
relationships between baleen whales and habitat features to provide information on distribution and use.
