| Abstract: | In some vegetation types, total fuel loading (phytomass) can be predicted by easily-measured variables such as vegetation type and height. A double sampling scheme is proposed in which fuel loading is estimated on a particular site by using quadrat sampling within patches of similar vegetation to develop a general prediction equation, and then line intercept sampling is used to estimate the mean of the easily-measured variables on the site. This method is applied to estimate the total fine fuel loading on a heathland site. |
