  1. 6. Modelling of stand basal area from leaf and plant area indices in boreal forest systems of Sweden

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Alex Appiah Mensah; [2018]
    Keywords : leaf plant area index; plant area index; Norway spruce; Scots pine; mixed forest; basal area; national forest inventory; Sweden;

    Abstract : Leaf or plant area index (LAI/PAI) is a useful biophysical indicator to characterize the interrelationships between forests and the atmosphere and offers greater potential to estimate productivity of forested landscapes. Recently, hemispherical photography has been used in a pilot study implemented in the Swedish National Forest Inventory (NFI) to estimate LAI. READ MORE
