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

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.
