Here's a You Tube video of Charles reading his poem Garden Noir.
Charles was lead editor, with Kathleen Dean Moore and Fred Swanson, of the volume In the Blast Zone: Catastrophe and Renewal on Mount St. Helens, which includes essays and poems by Ursula Le Guin, Kim Stafford, Robert Michael Pyle, Robin Kimmerer and others.
The Ecopoetry Anthology, a remarkable collection edited by Ann Fisher-Worth and Laura-Gray Street (Trinity University Press, 2013) includes Charles' "Millennial Spring" a prose piece with embedded haiku-like poems modeled on the Japanese haibun. The introduction by Robert Hass is an insightful overview. Click here for more info about this cool book.
