we have a big pond with a half acre island which we have used for summer grazing for goats for the last few years.
it was ungrazed for 20 years and 5ft high with plants but is now 50% bare soil. it was covered in willowherb but this has disappeared since the goats set foot on it. being an island, it doesnt seem to catch many seeds from land nearby.
we are wanting to reseed it but as it was rough soil from digging out the pond, it is still loose, sandy and stoney in places, not what you can call top soil as it was dug out from the 4ft deep pond. it is also steep around the edge but flat on top. it did have a tree but the goats have de-barked it

any ideas on the best seed to bind the loose soil together more but also is ideal for grazing goats?
im hoping to use the goats feet to help get the seed into the ground, but do i need to get the goats off once the seeds have started to germinate? (catching them will involve alot of trampling feet)
thanks
