As human populations inhabiting cities have grown dramatically, we have lost the ability to understand and even to see the natural world around us. We lack the vocabulary to describe our surroundings, and this lack of understanding limits our ability as citizens to contribute to political decisions about the landscape of cities, especially at the edges where land meets water.

Bay Lexicon, a field guide to San Francisco's shoreline, is a case study in establishing a working language for hybrid landscapes. Centred on a walk along the edge of the iconic San Francisco Bay, it documents, deciphers, and classifies the places and phenomena a person encounters - and the forces, histories, and interactions that underlie what is visible. In a unique synthesis of text and drawing, Jane Wolff applies analytical and representational tools based in design and documentary work to findings from the fields of geography, environmental and cultural history, public policy, urban ecology, and landscape studies. As our cities face increasing pressure caused by climate change, we will need to reimagine them in terms that do justice to their complexity. Bay Lexicon's methods for building landscape literacy are meant for translation, adaptation, and use far beyond San Francisco Bay.

Through activist scholarship that cuts across disciplinary boundaries and levels of expertise, this book examines how the landscape at the water's edge works, documents its historical evolution, brings its citizens' values to light, and frames conversations about how and why it might change.
