Many of the views and dramatic contrasts of light and shade Wright so carefully conceived throughout the property are nearly erased. An adelgid spray program has been in place since 2000, and Parnall and her team are experimenting with ways to protect the seedlings, as well as with alternatives to hemlock, such as white pine. But the canopy is much denser now than when Wright bough the denuded property, and the reduced light may be a big hurdle. "This is a 25- to 35-year project. We're really charting the course now," says Manitoga's executive director, Jean-Paul Maitinsky.
