Suppression of Sugar Pine by Douglas-Fir in a Northern California Plantation
Competition from naturally invading Douglas-fir severely suppressed a 56-year-old sugar pine plantation in northern California. Only 19 percent of the planted 3-0 stock remained. The average tree was only 38.1 centimeters (15 in) in diameter and 23.8 meters (78 ft) tall. Unless weeded of native conifers, sugar pine is not a suitable plantation species in this area.
