馬拉河
Massive amounts of deforestation in the Mau Forest region has changed the hydrology of the Mara River where its source is. The river dried up for the first time in the 2010s. There are invasive species of plants such as Siam weed, Prickly pear, Feverfew, Mexican sunflower. The western side of the park is growing at four percent in human population each year. The livestock numbers are growing as well while the area is getting turned into land for farming and demand for land rises. It is estimated 200,000 animals are killed by poaching every year.
