The Swallowtails of Market Street: an Extraordinary Tale of Urban Adaptation
Known for his creation of the Green Hairstreak Project and ongoing efforts to secure the endangered Mission Blue population atop Twin Peaks, San Franciscan lepidopterist/ illustrator Liam O’Brien will focus this evening’s presentation on one of the city’s least-likely natural habitats: the downtown Financial District. As hard as it is to imagine nature in this piece of the urban jungle, there is a story of miraculous adaption by our largest native butterfly: the Western Tiger Swallowtail (Papilio rutulus). Liam’s first book, The Butterflies of the Presidio, (co-authored with Matthew Zlatunich and produced by the Presidio Trust) will be published in the fall of 2012. Randall Museum Theater, 199 Museum Way, San Francisco CA 94114. 7:30-9 pm. For more information, go to www.sfns.org or contact Patrick Schlemmer at JKodiak@earthlink.net or (415) 225-3830. Free and open to everyone.

“WANTED WEEDS” at SF Flower & Garden Show
Mar 20 – Mar 24 all-day

“WANTED WEEDS”
This garden provokes and inspires conversation, questioning our values around European invaders. The garden will be mobile as beds of weeds roll around the expo floor. When we think of weeds, we think tenacious, invasive, opportunistic…all negative judgments. However these villains can be virtuous host plants, nectar sources, and medicinals. We place our natives on a pedestal; we have a somewhat pious attitude about what should survive and thrive. Do we desire a pure white nature? Perhaps this fantasy is not worth perpetuating? Maybe changing our attitude about weeds is the answer and the nature that we should look towards.

San Francisco McLaren Park Bioblitz
May 11 @ 7:00 pm – May 12 @ 5:00 am

Nerds For Nature is bioblitzing! And we need your help.

Join us on May 11 as we nerd out with biologists, botanists, and lepidopterists to observe and record the biodiversity of the Bay Area, starting with our kickoff event on May 11 in McLaren Park, San Francisco.

Details

Start time: 12 pm sharp (brief orientation and iNaturalist training session.)

End time: 5 pm

BONUS: Evening moth ID session with renowned moth expert Jerry Powell (he wrote the book on western moths)

What we’ll do

Nature Nerds, scientists, and amateur naturalists will work together to find and identify as many different species as possible within McLaren Park – everything from ants to redwood trees (called a ‘bioblitz’). We’ll break the park up into zones and even encourage some friendly zone-to-zone competition. Bring yourself or a group of friends! We have 300 acres to explore.

We’ll use iNaturalist, a smartphone app, to record and photograph what we see. Check out iNat’s place page to get a sense of all the cool stuff we might see! And we’ll build on this list too!

If you have a smartphone, we also recommend signing up for an iNaturalist account ahead of time. The morning orientation will review how to use the tool.
