When we make habitat for New England cottontails, aren't we destroying habitat needed by other wildlife?

Different kinds of wildlife require different types of habitat. There’s plenty of mature forest in New England and the Northeast for the animals that need that kind of cover. But there's not enough of the thick, brushy young forest and shrubland that New England cottontails need. Young forest and shrubland are short-lived habitats, lasting only 10 to 20 years before they get too old and important ground vegetation gets too thin. For that reason, we need to keep creating and renewing young forest and shrubland so there's enough habitat to support healthy populations of New England cottontails and more than 60 other kinds of wildlife that require such dense cover.
