Supporting evidence from individual studies
A replicated, controlled trial in 1984-7 on a reserve on the island of Islay, west Scotland (Percival 1993), found that more barnacle geese Branta leucopsis used wet pasture fields if they were reseeded, compared to if they were fertilised or untreated (reseeding increased dropping density by 60-135%; fertilisation by 17-42%, but not in all fields or years). The effect of reseeding declined over time, and as the overall area of rotational grassland on the reserve increased. Reseeding consisted of ploughing fields and sowing with a perennial rye-grass Lolium perenne dominated seed mix in May.
