Xiaohua,
Here we have been using Sigmascan to estimate herbivory, but it is very
expensive. There are other free downloadable packages, not quite as easy to
use but still not bad.
Generally, I am very skeptical that any automated scanning package can
reliably assess herbivory damage on temperate zone leaves with their complex
and highly variable lobed shapes. But simple leaves - such as are found in
tropical rainforest - might be done reliably using an automated system. For
temperate zone leaves, we can the leaf then take the damaged area 'by hand'
using a mouse and doing a calculation.
Regards,
Jonathan Adams
