Remove vegetation to create nesting areas
A controlled trial conducted over two seasons (1986-7) at two sooty tern Sterna fuscata breeding colonies in grasslands in the Culebra Archipelago of eastern Puerto Rico (Saliva & Burger 1989) found that terns did not nest in six experimental plots that had been entirely cleared of vegetation, but did nest in three plots in which partial removal of vegetation had resulted in 25%, 50% or 75% vegetation cover. In 1987, there were more nests in partially-cleared areas than in control (un-cleared) plots (58 nests in three regrowth plots vs. 40 in four controls).
