The Green Hairstreak Butterfly Corridor is an area of land, starting in the mid-Sunset and extending down to Hawk Hill Park, designed to be habitable to the locally-endangered Green Hairstreak Butterfly.  The Green Hairstreak butterfly can only fly a few hundred feet from its original habitat, so creating a range of habitable land for the butterfly is essential to its survival.

The corridor itself is a set of strategically placed plants, placed throughout parks and other green space.

The project was started in 2006 by lepidopterist Liam O'Brien and is currently maintained by Nature in the City.

The map on this page shows only the rough area of coverage of the corridor. For a more complete map, please see this link. (We can also add the spots here on LocalWiki, too!)
