The Adaptations and Response of Organisms to the Abiotic factor of Rainfall

Canada geese are dependant on the availability of fresh water at Race Rocks. During the winter, the higher level rock pools are refreshed by rainfall. There is no other natural source of water on the island. By the time their eggs hatch in June, most of the pools have dried up, so they have to take their young off the island and over to the mainland. They may make it past the eagles….(Photo by PB)

The availability of water for vegetation on Race Rocks has major implications for the species of plants which can survive on the island. Not only do they have to survive dessication from salt spray, but abundant water in the winter months and almost a total lack of water from June to September. One of the best grasses to tolerate these conditions is Fescue. Here you can see it growing on the natural rock outcrops on the island.
