%description
Simplifies the process of estimating above ground biomass components for
teak trees using a few basic inputs, based on the equations taken from the
journal "Allometric equations for estimating above ground biomass and leaf
area of planted teak (Tectona grandis) forests under agroforestry
management in East Java, Indonesia" (Purwanto & Shiba, 2006)
<doi:10.60409/forestresearch.76.0_1>. This function is most reliable when
applied to trees from the same region where the equations were developed,
specifically East Java, Indonesia. This function help to estimate the stem
diameter at the lowest major living branch (DB) using the stem diameter at
breast height with R^2 = 0.969. Estimate the branch dry weight (WB) using
the stem diameter at breast height and tree height (R^2 = 0.979). Estimate
the stem weight (WS) using the stem diameter at breast height and tree
height (R^2 = 0.997. Also estimate the leaf dry weight (WL) using the stem
diameter at the lowest major living branch (R^2 = 0.996).
