What does it mean to “preserve” a local ecology? “Wild” places hereabouts have been profoundly affected by human activity – Muwekma Ohlone tending and shaping the land, developers building the dam, others introducing yummy species for food. Perhaps we can preserve the functioning of a healthy ecosystem, allowing natural processes to come to equilibrium – and nudging the world toward a healthier state with strategic interventions.
Summer interns from Grassroots Ecology enjoy a tour led by Jerry Hearn and Helen and Dan Quinn. Sharp eyes draw my attention to interesting subjects.
Invasive Argentine Ants gather nectar and protect the galls of the Clasping Twig Wasp, native to California. Native birds and animals benefit from the wetlands above relatively recent Searsville Dam. Turkey Vultures, native to the entire west coast, feast on flesh of all. Invasive Bullfrogs threaten native species.
BONUS: as we arrive back home in Portola Valley Ranch, a Great Blue Heron departs the Frog Pond. We have just seen two others surveying Searsville Lake.
