Researchers Call ‘Field of Dreams’ Restoration Hypothesis Misguided If we build it, won't they come? —Mary W., Austin, TX The “Field of Dreams” hypothesis is a premise that restoration ecologists use to support arguments in favor of restoring plant diversity in that doing so will also lead to the return of wildlife. The hypothesis name comes from the 1989 film of the same name in which Kevin Costner heeds the “if you build it, they will come” call, building a ballfield in his cornfield which leads to all-stars from the ages showing up for an epic game. Conservationists would like to believe they can do similar things with land by reintroducing native plants so that animals will also return given the more hospitable surroundings.
