…..and who owns the forest ? and will they want what would be a pack of wild dogs hunting in it ?
Seriously, the kindest thing you can do for these dogs is to arrange funds or resources that pays for a vet to sterilise as many of them as possible.
Living as they do their life expectancy is a handful of years at best. If you stop the uncontrolled breeding (which is what human society did as they changed them from wild to domesticated) and by natural selection (or selective euthanasia of those who are unfit/injured, etc.,) reduce their numbers and improve their health, then they're no longer so likely to be viewed as pests.
At that point folks start to value them again.
Stray dogs numbers don't reduce by themselves.
If you feed them, then they breed.
A big heart is a good thing, but it needs a thinking brain to be effective.
