Climate, Trees, and Legacy: 02 - Lessons of Torrey Pine
Published on Mar 18, 2014
In this second installment of traveling across the USA in 2014 evaluating the need for "assisted migration" of trees in a time of rapid climate change, Connie Barlow focuses on America's rarest pine tree: the Torrey Pine of the foggy coast of southern California.
Her conclusions: (1) In this case, size of habitat doesn't matter; San Diegoans are so proud of their native tree that they are planting and watering it on lawns and street-sides. (2) Experience does matter — it matters greatly; though reading scientific papers is crucial for understanding the needs of trees, so is ground truthing. The venerable tradition of nature study and the kinds of simple outdoor experiments that Darwin excelled in will become increasingly important as plant zones head north faster than tree species can follow.
In addition to Torrey Pine, Connie encounters and draws lessons from Brazilian Pepper Tree, Navel Orange Trees, Cherimoya fruit trees, and California Torreya. She also reflects on the abundance of wind turbines in California and the drama of increasing drought and dwindling flows in California's aqueduct network — and thus the growing tension between residential and agricultural water demands in this most populous state.
The series host, Connie Barlow, is the founder of the citizen activist group Torreya Guardians. She is the author of "The Ghosts of Evolution" and is speaking along the 2014 route of The Great March for Climate Action (from Los Angeles to Washington D.C.).
