San Francisco, Biodiversity, and the Department of the Environment
We’re aware of San Francisco’s Department of the Environment as the first line of defense against toxic chemicals in our public lands. But they’re more than the defense-against-the-dark-chems guys. They’re the recycling guys. The energy saving guys. The community gardens … Continue reading

Interwoven and Integrated: Non-native and Native Species in Life’s Web

Twin Peaks, Glen Canyon, Natural Areas, and Imazapyr

Native Plants, Oxalis and the Futility of Garlon
