Look at these choke cherries, living in the zone between the grass and the aspens.
In the perfect water zone where birds that pass between trees (for shelter) and grass (for insects and seeds) leave them, and where tracking animals (bears, coyotes), who follow edges, leave them: right between water, shelter and light. The correlation between saskatoons and choke cherries deepens the map of the interface.
Interface gardening makes sense.
