[Wikipedia] Alameda County Population Note: One notable population occurs in the Cedar Mountain Ridge area of Eastern Alameda County. According to Carl Wolf, who extensively studied the New World Cypress in the 1930s and 1940s, seed from the Cedar Mountain stand of Cupressus sargentii produced the most vigorous seedlings.
