I'm amongst the designated "prospectors" and recon group so movements would not be limited at all really. It would be easier to explain on a map, but again.... I know nothing about such a place.
Excellent idea with the geese. Growing up, my grand parents had guinea hens (not sure if I spelled that right though) and those were also a more reliable alert system than dogs. So possibly a variety of bird options to consider. A concern would be that either can be heard from a relative distance and could attract undesirables, but... no more noise than a truck, tractor, atv, etc. so still a very viable/useful option in my opinion.
