In 2018 Creekside Science was awarded a Disney Butterfly Conservation Initiative grant for work with the federally endangered Mission blue butterfly (MBB). This grant covers work with MBB habitat, with a focus on restoration of the butterfly’s host lupine species.
In December 2019 Creekside Science staff and Kirra Swenerton (of Root Wisdom) installed 10 blocks of experimental seed plots on San Bruno Mountain using 50 Lupinus formosus and 50 Lupinus albifrons seeds each. In addition to those experimental plots, 10 operational plots were installed, each containing 50 seeds (25 of each species). Lastly, 3000 seeds (1,700 L. formosus and 1,300 L. albifrons) were set out in expansion plots elsewhere on the hill. These plots join last year’s Lupinus formosus experimental seeding trials to further our understanding of how best to establish lupines in MBB habitat. The seeds were propagated in the Creekside Science Conservation Nursery. This is all part of a regional, interagency conservation effort to support lupine diversification and habitat enhancement for the recovery of the MBB. In cooperation with multiple agency partners, efforts to address known habitat enhancement challenges through updated host plant mapping, lupine seed amplification and experimental direct seeding strategies are underway.
