On New Zealand's Banks Peninsula sits Hinewai, a reserve where botanist Hugh Wilson has spent decades letting a native forest reclaim farmland. The film opens in 1987, when Wilson announced to skeptical local farmers that he intended to retire grazing land and let gorse, long treated as a worthless weed, take over. Interviews with Wilson and shots of the reserve show why: gorse turns out to be a nurse plant, shading out grass and sheltering native seedlings until forest canopy closes over it and the gorse dies back on its own. The film follows this succession across the hillsides Wilson has managed, contrasting the tidy, controlled aesthetic most conservation projects favor with his hands-off approach of simply removing pressure and waiting. Neighbors who once mocked the scheme now watch native bush return where there was pasture. It is a quiet argument for patience over intervention, told through one man's decades-long experiment and the landscape it produced.
