The Ecological Staircases of Mendocino County

Original Publication DATE: 11/7/2012

A sequence of five elevated marine terraces along Jug Handle Creek in coastal Mendocino County constitutes a nationally and internationally famous ecological staircase. So outstanding is the combination of canyons, terraces and ancient dunes, tall redwoods and firs, bishop pine forest and dwarfed pines and cypresses that…It has become a Mecca for naturalists, botanists, ecologists, pedologists (soil scientists), geographers and nature-oriented laymen. It is being praised as the best preserved ecological showplace of coastal landscape evolution anywhere in the northern hemisphere.” –Hans Jenny 1973


Throughout the Pleistocene, as the climate fluctuated, sea levels rose and fell in conjunction with the size of the polar ice caps thus allowing oceanic wave-action to cut coastal terraces around the world. Subsequent tectonic forces then slowly pushed these terraces upward. What we now witness in coastal Mendocino County is, as Jenny states, the best preserved ecological showplace of coastal landscape evolution in the Northern Hemisphere.

Parque Nacional – Sierra de San Pedro Martir

This mountain range had been a place in my dreams for many years. I had heard about its rich conifer forest, that many of the conifers (and other plants of course) common within California reached their southern range extension here, and that a natural fire regime had been ‘maintained’ by mother nature. This was an intact a forest–in as natural a state–as we 21st century explorers might hope to find. The mountains themselves are part of the Peninsular Ranges which I was quite familiar with, having lived in the San Gabriel’s for many years.
