the exmoor pony has been part of the landscape for generations, but it s an endangered breed. now a project is underway to preserve the genetic material from the ponies to help safeguard the animals in the future. andrea ormsby has this report. these exmoor ponies are in a rush. they have an appointment for the annual health check and they don t want to be late. feet are ok, eyes all right, not too many burrs in your hair. lovely, she s going to the top pen, please. we have just marked this mare up, we have given her a look over to make sure she is well, she is carrying enough condition to get her through the winter. and so far they are looking good? looking good, very pleased, yes. the wallace family from near dulverton on exmoor have been guardians of the anchor herd for more than a century. it s one of the founder herds, and the biggest purebred herd in the world. so no pressure. it is a responsibility. i do sometimes get quite emotional about it because it s just a lovely heritage
