Evolution, Ecology and Floristics in Northern California - Current Knowledge and Unexplored Realms

Schierenbeck, K [1].

A confluence of mountains and floras, or why Northern California is a great place to study evolution.

THE geographic region roughly defined as the northern third of California has high floristic diversity resulting from a confluence of three major floras. Ancient and recent geologic changes have resulted in a complex of edaphic habitats. Although some habitats (e.g. wetlands, Sequioa sempervirens forests) have been impacted dramatically, many relictual and recently evolved plant species and communities have experienced relatively little anthropogenic influence. Large contiguous areas of publicly owned land provide the ideal circumstances for ecological and evolutionary studies across multiple spatial and temporal scales. Of timely interest are questions regarding recent speciation and reticulate evolution, the impact of climate change on paleo- and neoendemic taxa, and landscape level conservation efforts. Projections for human population growth in Northern California indicate an immediate need to increase the documentation, understanding, and conservation of this area.
