The Great Elephant Census | HHMI BioInteractive Video

How many African elephants are left and where are they? This video follows the work of researchers conducting the first census of African savanna elephants in over 40 years and the methods they are using to obtain accurate, up-to-date numbers across the continent. African elephants are threatened by habitat loss and by poaching to support the ivory trade. Conservation groups estimate that as many as 100 elephants are killed each day, so it is critically important to determine how many elephants remain and where they are. Scientists involved in the Great Elephant Census project (founded and managed by philanthropist Paul G. Allen) are conducting aerial surveys across millions of square kilometers to obtain accurate elephant census data. This video describes the strip transect sampling method they are using and how elephants are counted.
