Site productivity assessment in rain forests: An objective approach using indicator species

Site pro ductivity assessment is a prerequisite fo r gro wth predictio n and yield fo recasting. Site index (to p height at an index age) is no t suitable in rai n fo rests where tree height is difficult to measure and tree age is impo ssible to determine. This paper repo rts a study which ranked 80 permanent plo ts acco rding to po tential diameter increment, and esta blished equatio ns which allo w site pro ductivity to be determined firm the presenceo r absenceo f se veral tree specieso r fro m geo lo gical maps and Landsat TM data
