The possible options are to conserve large areas and build in flexible boundaries for seasonal changes to accommodate uncertainty, as well as to build networks of MPAs as described in Section VII. Alternatively, for some populations such as southern community killer whales in the northeast Pacific, research has shown that targeting feeding hotspots as protected areas could confer the greatest conservation benefit because these whales have been shown to be the most susceptible to being disturbed while feeding, compared to traveling, socializing, or resting.
