Warden's Seed Rescue Saves Rare Cow-Wheat Colony

- Crested cow-wheat (Melampyrum cristatum) is a rare hemiparasitic annual restricted to a small part of eastern England, relying on ants to drag its oil- and protein-rich seeds underground where they germinate in nest soil.
- An 1980s colony near Ufford declined after rabbit populations fell, allowing grass to grow long enough to smother the shade-dependent plant, and the population eventually vanished.
- A reserve warden, seeing the Ufford colony fading, harvested seed and transplanted it to a site where plentiful ants and winter cattle grazing now keep the sward open — conditions that sustain the rescued population of thousands of plants.
- Sarah Lambert, on her annual visit, describes the rescued colony as a tangled abundance of primrose-coloured tubular flowers that flush magenta with age, growing alongside orchids, wild liquorice and common valerian.
Why it matters: The piece illustrates how one 1980s seed rescue by an unnamed reserve warden preserved Melampyrum cristatum locally in eastern England; the transplanted colony now depends on specific ecological conditions — winter cattle grazing to suppress grass and abundant ants for seed dispersal — that were precisely what the original Ufford site lost, showing rare-plant survival is conditional on active habitat management.
