This interactive module explores methods used to survey large animal populations, and what they have revealed about the current state of the African elephant population.
African elephants provide a powerful case study for how science can inform conservation. Knowing how many elephants are left and where they live is important in devising strategies to protect them. In this Click & Learn, students consider the advantages and disadvantages of different methods and approaches that scientists use to measure and monitor elephant populations.
The accompanying worksheet guides students’ exploration.
