Ms. Russell & Earthwatch Team,
My class and I started to discuss your trip to Kenya today. We spent some time discussing the main research question.
Why is the zebra population decreasing?
The class would like to know your thoughts regarding this question.
We took a poll in class today. The following are the results:
Disease 12
Climatic Change 6
Lack of Vegatation 4
Currently the Grevy's Zebra are threatened by a combination of challenges. Predation by Lions. The lions prefer to eat Grevy's over Plains Zebra. The very long drought-which has forced the zebras to travel farther distances to find water, which in turn changes the mares body from nursing their foals to survival. A mother zebra must have a good source of a water on a daily basis to produce good milk for their baby. Finally they are in competition with the Plains Zebra for the available grasses. Because there has been very little rain the Grevy's Zebra are eating very tough, very short grass that cuts their lips which then creates a bacteria (disease) that causes their death. The research we conducted on this trip will assist the scientists in determining the best possible way to help the Grevy's Zebra for the future.
