The San Francisco Peninsula ecoregion occurs at the northern end of the peninsula, with a climate affected greatly by the marine influence. It is cooler than much of adjacent Ecoregion 6t, and fog is common. Soil temperature regimes are mostly isomesic, with some thermic on the bay side. Some metamorphosed sedimentary and volcanic rocks occur, but large areas are covered by Quaternary marine and sand dune deposits, with recent alluvium and large areas of fill on the bay side. There are some small serpentine outcrops and bluffs. Natural vegetation consisted of California oatgrass, purple needlegrass, coast live oak, California bay, dune communities, and some saltmarsh species. Some rare and endangered plant species persist. Like Ecoregion 6t, the San Francisco Peninsula ecoregion is nearly all urbanized.
