Golden Hour has partnered with the US Fish and Wildlife Service Partners in Wildlife Program, the San Francisco Recreation and Parks Division, and butterfly maven Liam O’Brien to begin a 3 year stewardship program that will emphasize habitat enhancement for the federally threatened Mission Blue Butterfly.  USFWS will be helping fund this extraordinary project which will help maintain critical habitat for the butterfly long term.

Here is an adult Mission Blue male (although difficult to tell from this photo) resting on a silvery bush lupine waiting for the sun to emerge and the dew to burn off.

Liam O’Brien coined the term “Mission Blue Crew” for regular group of volunteers helping maintain habitat for this butterfly which was nearly chased from the top of Twin Peaks with its habitat being replaced by development. With years of professional translocation, monitoring, and stewardship work, there are now many hundred eggs that are regularly located on lupines on Twin Peaks, indicating the butterfly is slowly recovering.

We tested out a volunteer day in April when the Blues were flying and are now ready to scale this up to an 8-day-a-year project wherein trained volunteers have the opportunity to work as habitat stewards in various stage of this butterfly’s life cycle. Although adults can only be spotted flying for about one month out of the entire year, there is much work outside of those months that needs to take place.

Please inquire with us about opportunities and we’ll make sure it’s a good match for the goals of the stewardship program.

I’m interested in Mission Blues for awhile. I was a docent at Botanical Gardens, SF and Member of CNPS and saw Lech Naumovich do a wonderful presentation on Oct 2, 2014 @ SFCFB. I bike ride up Twin Peaks often and thought the two interests would combine well. I have noticed in the last 1&1/2 years the increase in autos, parking, litter, trashing the trails and just wandering of people on the loose. I know there must be a way to suggest to people to stay on the paths. Actually we had no smoking signs up there at one time. I know this may be of interest, because the results could help save our endangered species. I know Funston helps seed plants. Are they later transported to Twin Peaks to assist the Mission Blues?

Thanks and look forward to hearing your reply.
