Distribution and Habitat
The Mendocino Cypress is highly variable in growth form, depending on soil conditions. In the pygmy forest plant community on poor, acidic, nutrient-starved podsol soils with drainage impeded by an iron hardpan, it is a stunted tree from 0.2–5 meters in height at maturity. When occurring in its pygmy form, it is sometimes called Pygmy Cypress. When growing on deep, well-drained soils it can be a large tree up to 30–50 meters in height and 1–2.4 m in trunk diameter. The bark is dark gray-brown, with stringy texture, and fissured on old trees.
Mendocino Cypress occurs in very limited ranges within only Mendocino County, on some of the historical lands of the Yuki Native American people. In Mendocino County the occurrence is in a discontinuous coastal terrace strip, primarily as a pygmy forest associated with Bishop Pine (Pinus muricata) and Mendocino Shore Pine (P. contorta var. bolanderi). Occurrences are typically below 500 m in elevation. The Mendocino County official soils survey states that "While not formally recognized as a major forest cover type, the coastal portion of the survey area also includes Bishop Pine and Mendocino Cypress (pygmy) forest types".

Famous quotes containing the words distribution and/or habitat:
“There is the illusion of time, which is very deep; who has disposed of it? Mor come to the conviction that what seems the succession of thought is only the distribution of wholes into causal series.”
—Ralph Waldo Emerson (1803–1882)
“Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.”
—William James (1842–1910)
