Different methods described for estimating above-ground biomass are being used by different stakeholders. Among all the methods, biomass (including volume) estimation equations are likely to be applied the most. However, the number of species for which such equations are available is limited. In the absence of species-specific biomass equations, generic biomass equations are frequently used. Thus, it may be desirable for project developers and inventory experts to develop region-specific and species-specific equations. Once developed, they can be used for other projects in the region. In the absence of biomass equations, the simplest method is to estimate the volume of sample trees using DBH, height and the form factor and then converting the tree volume to tonnes of biomass by multiplying with wood density.
Non-tree biomass includes shrubs, herbs and grass biomass. Herbs and grasses are annuals, whereas shrubs are normally perennials. The focus of forest and plantation managers and greenhouse gas inventory experts is on tree biomass. However, non-tree biomass may have to be estimated for climate change mitigation projects, grassland development projects and community forestry programmes. The harvest method is used for estimating non-tree biomass in forest and non-forest land-use systems.
