The flora of Grip. A story of increasing species diversity.

Grip is a small island 14 km NW of the town of Kristiansund in western Norway. The settlement, from the early Middle Ages, has always relied on fishing. Since 1974, the island has had no permanent inhabitants. Over the years, practically all the vegetation has been removed, especially to provide bare rock for drying fish. Five lists of vascular plants, from 1936, 1947, 1969, 1996 and 1999 are compared. Although there are many doubts about their representativity and completeness, the lists indicate an increase in the number of species. Many of the (presumably) new species are either ruderal or exacting as regards soil depth and nutrient content. Six woody species are assumed to occur spontaneously, having been carried to the island by wind or birds. The vegetation cover on the island is slowly recovering.
