Fig. 3From: Within-tree, between-tree, and geospatial variation in estimated Pinus radiata bark volume and weight in New ZealandVariation in the ratio of green bark density (GBD) to green wood density (GWD) with height in the stem for 25- to 26-year-old radiata pine trees from central North Island sites. Log height classes are in increments of 5.5 m: 0–5.5, >5.5–11.0, >11.0–16.5, >16.5–22.0, >22.0–27.5, and >27.5–33.0Back to article page
