They are often under water for significant periods of time, meaning that they are frequently deprived of oxygen. AWF works with pastoralist people to develop appropriate sustainable solutions for agricultural and settlement growth by providing training on best practices and incentivizing conservation when appropriate, like in the Congo where we provided pastoralists with increased seed varieties and new planting techniques. These groups maintain distance from one another through territorial calling. Colobus monkeys are active during the day and are able to make long leaps between trees.

Now I wont get into all the science that goes into the process, but to sum it up, their stomach contains a bunch of microbes that ferment and break down all those leaves which then allows their body to absorb the nutrients.
