Buffer strips are designated “protected” areas of land we build using native plants, grasses, shrubs, or trees. They are highly effective in protecting soil and water quality by slowing runoff, reducing sediment loss, and filtering nutrients (nitrogen and phosphorus), and pesticides before they reach streams, wetlands, or other sensitive areas, like the Chesapeake Bay. They support pollinators, improve habitat, and enhance biodiversity by creating a corridor of natural vegetation.
A CRP CP-33 “bobwhite buffer” consisting of little bluestem and broomsedge grasses mixed with wildflowers. The bluebird boxes mark the buffer edge for farming. We often place the boxes in pairs, as one will usually be occupied by tree swallows, which will not tolerate other swallows but will allow bluebirds to nest in the adjacent box.
