We all enjoy the 4th of July festivities, the fireworks, all your friends and family gathered at the beach to gaze up in the night sky and the beautiful displays of pyrotechnics. What we all forget to do sometimes is look down, at the beautiful landscape on which we stand. We forget that all these events create tons of trash, lots of it single use plastic. ( straws, wrappers, packets, bottles…. the list goes on). This year The Aquafriends decided we needed to help our shorelines survive another onslaught of people just dropping their trash anywhere. We organized a July 5th Day After beach cleanup. We want to thank the SAN CLEMENTE WATERSHED TASK FORCE for supplying the bags, gloves, and grabber claws. and we cant do this without the dedication of our volunteers. THANK YOU ALL SO MUCH for the 43LBS of trash we collected. #saveourseas #nomoreplastic #theaquafriends

We have some sad news to report. 😢 🦁
On March 21, NPS biologists hiked in to the central portion of the mountain range after P-47's GPS collar sent out a mortality signal. They found the three-year-old mountain lion’s remains and noticed he did not have any visible wounds. A necropsy revealed that he may have succumbed to poisoning from anticoagulant rodenticide, commonly known as rat poison. Testing on a sample of his liver showed that he had been exposed to not just one, but SIX different anticoagulant compounds! Internal hemorrhaging was also found in his head and lungs.
Although it’s not known exactly how P-47 ingested the poisons, researchers believe mountain lions are exposed through secondary or tertiary poisoning, meaning that they eat an animal that ate the poisonous bait, such as a ground squirrel, or an animal that ate an animal that consumed the poisonous bait, such as a coyote.
Researchers first marked P-47 when he was around four weeks of age at the den with a tracking device. He was later fitted with a GPS collar in January 2017 when he was 14 months old and weighed 108 pounds. At his last capture in January 2018, he weighed in at exactly 150 pounds, which tied him for the largest among all the mountain lions in the history of the NPS study.
Biologists have documented the presence of anticoagulant rodenticide compounds in 21 out of 22 local mountain lions that they have been tested, including in a three-month-old kitten. 😔 Lab results for P-64, who died a few weeks after the Woolsey Fire, also found six different anticoagulant compounds in his liver.
