Point Reyes Seal Colony


Elephant seals are some of the most interesting and unusual creatures that can be found on the Point Reyes Peninsula. During the 1800’s there were countless thousands of these marine mammals ranging from Baja Mexico, to Point Reyes California. Not unlike whales the seals were hunted nearly to extinction for their oily blubber. Being extremely large one bull elephant seal will yield almost 25 gallons of oil. Although it is unclear how many elephant seals there were in the past it is believed that there were only 1000 left by 1910. In 1922 the Mexican government put a ban on hunting the animals in the attempt to protect them, and shortly after this United States followed suit. Thanks to government protection, and the fact that the animals spend almost all of their lives at sea the population has risen to an estimated 150,000.(Nps.gov/pore) In the 1970s, after being gone for almost 150 years, the seals were sighted again on the sandy beaches of Point Reyes. The first breeding pair was discovered near Chimney Rock in 1981.(Nps.gov/pore) Since then there has been a drastic increase in population with an annual average increase of 16%. The estimated seal population of Point Reyes is now between 1500 and 2000.(Npss.gov/pore) Dispersing from the original breeding spot the seals have formed several new colonies and continue to spread out onto popular beaches. Including the formation of a new colony last breeding season on Drakes Beach that included three females.(Sarah Allen Interview)
