The Farallon Islands are host to five species of pinnipeds (seals and sea lions). For over one-hundred years, human occupation and hunting decimated much of the wildlife on the island and Northern Elephant Seals and Northern Fur Seals were extirpated in the 1800's. The Elephant Seal began re-colonizing the island in the late 1950's and in 1972; Point Blue witnessed the first pup born there in over a century. More recently, in the last two decades, Northern Fur Seals have begun to return to the Farallones and their populations have grown at an extremely rapid rate. Point Blue continues to monitor these colonies to gain a better understanding of the population dynamics of all seals and sea lions on the Farallon Islands.
