Food and water
Most of the time, there is plenty of food and fresh water on Sable.
But in some seasons the horses must struggle to find nourishing plants
or a source of drinking water.
|
| The horses
grow fat grazing on lush summer plants. Summer fat is the key to
surviving hard winters, because the dried winter leaves of Marram
are not very nourishing.
|
Horses can sense where to dig for
water in a dry season.
|
|
|
Teeth and sand
Imagine chewing sand every day. The
horses take in a lot of sand as they graze. Hard quartz sand grains
wear down their teeth. Horse teeth keep growing for about 6 years,
so tooth wear is not a problem at first. But older horses may starve
when their worn teeth cannot grind the tough Marram.
