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.
