If there was that much poop, there were too many animals left on the land too long. And they should have used sheepies instead of goats. Goats are more browsers. They'd be excellent for flash grazing (overstocking but moving away after, say, 48 hours, 72 max) an area with weeds and a little woody stuff coming in. But sheep would crop the grass nicely if managed correctly.
People would often ask about the advisability of buying sheep to keep their lawns down. They're overlooking the way grass grows. In the east, if you have enough sheep to stay ahead of the grass in the Spring, you have way too many for the rest of the summer.
Of course you are right, and I knew that too.
The problem is that is always what happens when free enterprise meets liberal politicians.
The politicians wanted the field "mowed" in the shortest time at the lowest cost, so they hired someone who trucked in a completely non-sustainable number of goats right after the grass & weeds had achieved their maximum growth. That way, one grazing period of a week or so reduced all of the grass to goat poop.
That way, the politicians look good, the newspaper reporters, whose shoes have never touched anything other than carpet indoors and concrete outdoors, gushed glowing reports, and anyone who wanted to actually used the land was shafted.
My brother bought an abandoned farm with about 7-10 years trees/vines. He bought two goats and everyday would manually cut brush and the goats would strip it then he’d burn the sticks/stems. Good in theory but slow in practice. After a year he bought a bush hog and the goats are now pets.
