Japanese honeysuckle, Chinese privet, Bradford pear, Chinese mimosa, also fill the woods and fence lines.
In southwest Oregon, wild blackberry bushes can be planted
near water like the edge of a river or stream.
Blackberry bushes grow huge and produce an astounding
number of berries.
When I lived in SW Oregon I lived on a road that dead-ended
at the North Umpqua river - and there was a HUGE mass of
wild blackberry brambles between the dead-end and the river.
Some mornings I would take a bottle of water, a colander and
a spoon down to the end of the road, pick berries off of
the bushes, rinse them with water, sit down on the grass
by the bank of the river, and eat them. There is no better, pleasant
and free breakfast that I know of.
When I was a kid we had honey suckle completely engulf the chain link fence across the back of our yard. We got two white pekin ducks for Easter one year. By the next year the honey suckle was almost gone. They ate it all.
