| a Primary source: Barbour et al. (1991). Figures are for vegetation types throughout the state of California. They have not been recalculated to exclude desert areas east of the CFP and include the Oregon and Baja California portions of the CFP. For the vegetation types listed, percentages of change for California are probably similar to those for the CFP. Figures originally given in acres were converted to ha with the same number of significant digits. | |||
