We have some nice hedges along fence rows but our tall trees are also all over the place.
Using these trees, it's easy for predators like hawks and owls to pick them up.
Our fence rows could have 10 ft. of weeds and grass beside them but enough tall trees are always on fence rows.
Some places in Michigan where I used to hunt discourage tall trees along fence rows.
I noticed places I've observed in Iowa that has good Pheasant population don't have tall trees like next to railroad right of way.
