About the Image

A coastal prairie and UNESCO Biosphere Reserve north of Lincoln City, Oregon, USA on the Pacific Ocean. The ungrazed promontory of the preserve supports a diverse flora and fauna, including rare and endemic species. Color-coded organza bags were used to retrieve inbred and outbred progeny from hand pollinations of the rare Silene douglasii var. oraria (inset) for reintroduction. Transplants of outbred progeny had higher survival over 5 years than the inbred progeny in this headland (foreground), and seedling establishment was lowest for the rare variety in natural and experimental plots. This case study will facilitate the design of larger scale attempts at successful reintroductions.
