|birds love native grasses like this|
In north Texas we're fortunate to have many kinds of native grasses (sometimes called "ornamental" grass) to choose from. Some favorites of mine are Little Bluestem, Sideoats Grama, Lindheimer Muhly, Indiangrass, Eastern Gamagrass and Windmillgrass. These grasses are NOT your typical lawn grass; heights of native grasses range from 4 inches to 6 feet, they're drought-tolerant and almost maintenance-free.
A group in Louisiana has a clever idea - one of those "that's so obvious I should have thought of it" ideas like we all have sometimes. They acquired a number of birdhouses for a scenic trail, and had each one engraved with a mile number to indicate how far along the trail you were (the inhabitants don't care if there's a big "4" on the wall).
It not only reduced the need for a huge number of signs, but will increase the total bird life.
