Stomatal density and stomatal index of many species respond to atmospheric CO2 (Woodward, 1987; Woodward and Bazzaz, 1988) but are influenced
by other environmental variables as well (Poole et al., 1996).
By combining the CAO laser information with satellite maps of forest cover, deforestation, and
other environmental variables generated by the Peruvian Environment Ministry's Directorate of Land Management, a cost - effective means to monitor the country into the future has been established.
