The Spring 2015 Origins Field School students are now settled in at the Turkana Basin Institute and have been busy with the Ecology Module for the past few days. One of our first lessons has been looking at the vegetation. In this arid region, plants are essential for animals, including livestock, which is what supports the livelihood of pastoralists. As livestock graze on plants, they shape the vegetation community and plants respond in different ways. One of the most important species for goats, sheep and camels in this region is the short, spiny plant called Indigofera spinosa.
