I have about 3.5 acres of total land and it is essentially split right in half by a small creek that runs year round. One side is mostly grass and about as flat as it gets in the appalachian mountains with a few dispersed trees. the other side is a fairly steep (40%) forested area. The property essestially all slopes towards that creek in some way. The former owner maintained short grass and kept all creek side growth very small.
As I consider my design a big question is introducing animals but not negatively affecting the water. Almost everyone around here just gives free access to creeks and streams to goats, sheep, horses, cows, etc and they leave essentially no riprarian buffer. SO I am looking for some good info on managing this scenario. I would like to keep sheep, goats(pulsed most likely), ducks , and chickens (all in reasonable numbers) but I dont want to have negative impact on the water. So im looking for good info on how close is too close? If they are rotated and there is a riprarian buffer is it ok. Obviously I dont want to be putting lots of manure in water but simultaneously wild animals obviously poop close to and sometimes in water.
I appreciate any info
