I want to start off this post by celebrating my dear friends that I have made at the intern housing. These art folks that are participating in different projects at Point Reyes, including archeology, fisheries, range management, exotic plant and wildlife monitoring, and habitat restoration. We learn from each other and discuss the many facets of research and natural resource management that go into maintaining a successful national park. This past fourth of July weekend, we roadtripped to Mono Lake and made a stop in Yosemite for some outdoor rock climbing. This was my first visit to these parks. I remain speechless by their beauty and am so thankful for the wonderful company I had with me.
After a long weekend, I went back to work (still can’t believe that what I do is considered work). I had the incredible opportunity to help a masters student, Tracy, from San Diego State University on her crab diversity research. She is comparing the crab species in two estuaries, Elkhorn Slough and Drake’s Estero. Drake’s Estero is a beautiful estuary in Point Reyes that has just undergone an extensive eelgrass restoration project, which is great habitat for crabs! The photo to the right is my supervisor, Ben, who was driving the National Park’s boat for us.
On Wednesday, we set out six sets of two different sized traps. The larger trap targeted crabs while the smaller trap targeted fish, specifically the Pacific staghorn sculpin. The next day, we went back out on the boat to see what we had caught. Over the course of the week, we came across three different species of crab, Below is a photo of a female Metacarcinus gracilis, or slender crab. I loved these crabs because of their beautiful, purple color.
We pulled the crabs out of the cage and measured their carapace (the upper shell) at its widest point, determined the sex, identified the species, and then released them. For the fish, we only measured their length before releasing them. Tracy said the crabs caught in Drake’s Estero were massive compared to those in Elkhorn Slough.
This was such a cool week. While out in the estuary, we saw leopard sharks, bat rays, harbor seals, and river otters. It’s difficult to describe how incredibly lucky I feel.
