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!

Copeland Creek “Clean-up”

- Wendy

Last weekend, we had the first Copeland Creek event of the fall semester: a clean-up sponsored by JUMP and the Friends of Copeland Creek campus club. We had a small turnout, but it was a fantastic day out on the creek! Originally, we’d intended to pick up garbage and go after some of the Himalayan blackberry that’s creeping back into the restoration areas. When we went out to get started, however, I decided that there was more wild radish to be dealt with (and it’s much easier to work with than the blackberry – no thorns!!), so we had a radish-removal day instead.

Planting Graminoids!

- Wendy Leave a comment

Yesterday and today, we achieved a big milestone in the Copeland Creek riparian restoration project: putting in some native plants! For this first phase of planting, we started out with grasses, rushes, and sedges (collectively known as “graminoids”), all of them planted near the spot we call Snowberry Corner.

The plants were cultivated here on campus, by the Native Plant Propagation class – they provided us with more plants than we were able to get into the ground! Here they are in the greenhouse, the day before our first planting day:

Copeland Creek Work Day

- Wendy St. John Leave a comment

After months of planning, on Saturday, March 25, a group of volunteers gathered on the Sonoma State University campus to start the “muddy boots” part of our project to restore the riparian habitat along Copeland Creek. Over the past couple of weeks, our SSU project team identified native plants that we want to keep, and today our work team pulled up invasive species around these natives, to give them the best possible chance to thrive, and to make certain they’re not accidentally pulled up during a future phase of restoration work.  (All photos © the author, except where noted).

Wildlife on Copeland Creek

- Wendy St. John Leave a comment

On Saturday, March 25th, SSU collaborated with the California Conservation Corps’ Watership Stewardship Program to start work on our riparian restoration project (more details about the work we did on Saturday coming soon). One of the side benefits of working alongside the creek is encountering some of the wildlife that shares the campus with us. Here are a few of the highlights of our day . . .

Salmonid Field Trip

- Wendy St. John Leave a comment

Restoration Ecology’s final field trip of the Fall, 2016 semester was a wonderful adventure in the redwoods, looking at restoration projects aimed at restoring habitat for salmonid fishes, including chinook and coho salmon. Our hosts for the day were Sarah Phillips of the Marin Resource Conservation Department (RCD), Erik Young, a lawyer affiliated with Trout Unlimited, and Eric Ettlinger of the Marin Water District. Each of them shared with us a different perspective on the creek, and how restoration projects happen.

We started out in the Leo T. Cronin parking area for a brief introduction, and then we headed a bit downstream of the lot for our first close-up look at Lagunitas Creek.

Environmental Forum

- Wendy St. John Leave a comment

I was invited to speak as part of this year’s Environmental Forum at SSU, a lecture series put on by the Environmental Studies and Planning Department. I had a GREAT time giving this talk – I focused on the salmonid restoration that’s been done on Dutch Bill Creek near Occidental, and it went really well. The students were attentive, and asked a bunch of great questions at the end. Loved it!

Ready, Set, Reintroduce!

The Presidio’s Mountain Lake restoration is moving forward this year with several native species reintroductions. The Sierran chorus frog (Pseudacris sierra), is slated to be the first species reintroduced. This species was extirpated from the Presidio sometime in the 20th century and, although common throughout its range, has become very rare in the city of San Francisco. The first phase of the reintroduction will take place in February, when chorus frog egg masses will be placed in protective enclosures to keep them safe from predators as they acclimate to Mountain Lake. The tadpoles that hatch in those enclosures will then be released into Mountain Lake in March. Later in the year, threespine stickleback and the Western Pond turtles will also be reintroduced to the lake.

Reintroduction projects offer a wide range of opportunities for scientific exploration and citizen science engagement, so the Presidio Trust has been partnering with several organizations and institutions to broaden impact and expand knowledge in the fields of reintroduction biology and urban ecology. For instance, partners at Stanford University just published research on the potential to achieve improved water quality from the reintroduction of freshwater mussels, and the California Academy of Sciences produced an excellent video on the Mountain Lake restoration, including upcoming species reintroductions. Keep an eye on the Presidio Trust website and social media for more reintroduction-related news and events throughout 2015. It’s an exciting time in the history of Mountain Lake!
