Adorable baby Western pond turtle discovered at S.F. lake in Presidio, a sign of ecological comeback

- Wendy Leave a comment

This article is from April, but it’s the first I’ve heard of this. The turtles we reintroduced to Mountain Lake in SF have HAD BABIES! This is amazingly good news! These turtles had been extirpated (driven locally extinct) from the lake at some point in the past, and the fact that the introduced turtles are able to reproduce means that this population might be able to sustain itself into the future. LOVE THIS SO MUCH!

Ecosystem Exploration

- Wendy Leave a comment

This week, I’m using some Virtual Field materials in one of my classes (Ecosystem Exploration: https://thevirtualfield.org/virtual…/ecosystem-exploration).

In addition to the questions provided with the videos, I’m going to ask them to do some additional field journaling, including sketches. Here are the two I drew as examples (based on the Mojave Desert video), to give them some inspiration. (They aren’t expected to render things as completely as the tortoise, but the level of detail in the plant illustration should be doable by everyone).

As an aside, I think that Gopherus agassizii was the first scientific name I ever learned. My parents had hand towels with these tortoises (along with the name). Wow. It’s not actually too surprising that I’m such a nerd.

SAFE Western Pond Turtle Video

I might be biased, but this is a fantastic video about western pond turtles . . . the segment starting at 5:00 features the field site where I did my thesis research. The fellow being interviewed is my advisor, Nick Geist. And that’s your’s truly measuring the turtles in preparation to release them back into the lake. SO FAMOUS! 🙂

These Crazy Cute Turtles Want their Lake Back

- Wendy St. John 2 Comments

Hey, these are MY turtles! (Well, not just mine, but these are Geist Lab turtles. So I guess I could call them OUR turtles).

“Boxed in by a freeway, a golf course and a neighborhood, it’s a miracle that San Francisco’s Mountain Lake even exists. But not only is the tiny lake—located on the south end of the city’s Presidio park—still there, it now provides one of the few places in San Francisco where visitors can watch California’s only native aquatic turtle bask in the sun.”

At Mountain Lake, One Last Chance to See the Turtles Off

Another Bay Nature article featuring turtles from our lab. I’m quoted in this one!

“This turtle release is symbolic of so much transformation,” said Michael Boland, chief of planning, projects, and programs at the Presidio Trust. Mountain Lake, he said, is not just about Mountain Lake, it’s about how the environment is managed: “Nature survives in cities because of people.”

Which, said Sonoma State lecturer Wendy St. John, is one reason the project has succeeded. People around the lake have rallied to its restoration. “This is their neighborhood, not just a touristy area,” St. John said. “It’s been a community effort.”

Native Turtles Return to Mountain Lake

Although no one knows exactly when western pond turtles vanished from Mountain Lake in the Presidio of San Francisco, they are known to have been abundant historically. Now, as part of the ongoing restoration of Mountain Lake, this long-extirpated species is back. On July 18th, 28 western pond turtles reared by the San Francisco Zoo were released into the lake before an audience of more than 70 people. The release follows similar releases of other native species including Pacific chorus frogs and three-spined sticklebacks earlier in the year.

The western pond turtle release is also part of a research effort to determine which of two different release methods is better for the turtles in terms of their stress hormone levels. Half of turtles were brought to Mountain Lake and kept in a protected enclosure for three weeks to acclimate ahead of their release, while the rest were released without an acclimation period. All had their stress hormone levels measured upon their release and are equipped with radio transmitters so they can be relocated and have their hormone levels re-measured in the coming weeks and years. The preliminary results will inform another round of western pond turtle releases at Mountain Lake on September 12th and contribute to knowledge about native species reestablishment efforts in general. Future reestablishment projects at Mountain Lake may include the Pacific newt and the California red-legged frog.
