Thank you for your excellent service. It corrected many mistakes and indeed improved my manuscript. Many of the questions that you asked are related to professional jargons, as you probably have figured out already. Some of them are forestry related (plantation forests, thinning from below, etc.) and some are statistics related. My potential readers will have no problem in understanding what they mean.

With Best Regards,
