In this video, she describes the rich diversity visible from a map of south Santa Clara Valley.It represents landscape from the time of European American settlement: wetlands, marshes, etc. She explains how native habitats are robust, complex, dynamic, interesting, and how native californians managed them while providing/maintaining diversity,

Ruth Askevold examines maps with grids, the USGS Topo map, township and range from 1812, and the history of US surveying in California Bay area.
