Data for the ultrasound estimation of log MOE from non-destructive standing tree measurements7.75 kB
DataCC BY V4.0, Open Access
Data from 68 pine hybrid trees (Pinus elliottii var. elliottii x P. caribaea var. hondurensis) sampled in southern Queensland (note no data exists for tree 61, hence tree numbers range from 1 to 69). The trees were collected from three sites in the southeast Queensland plantation estate owned by HQPlantations. Tree sizes were stratified by diameter at breast height, to ensure we collected the full range of sizes in the plantations. Ages of the trees ranged from 19 to 28 years.
23 variables in columns and 69 lines of hybrid pine data:
1. Tree#: Identifier for the tree 2. Stocking, 3. DBH: Diameter at breast height (1.3 m) overbark 4. Whole log Density: Average density of the approximately 8 m log 5. Whole log Density: Average density of the approximately 8 m log 6. Whole log MOE: 8 m log MOE estimated using resonance acoustics and log density 7. Butt Log Dia: Large end diameter of a 1.3 m peeler log taken from the bottom of the 8 m log collected from the field (between discs 1 and 2) 8 . Butt Log density: Average density of the 1.3 m bottom log (between discs 1 and 2) 9. Butt log MOE: 1.3 m butt log MOE calculated using resonance acoustics and density measured on the butt log 10. Sawlog Log Dia: Large end diameter of a 3.9 m sawlog log taken from the middle of the 8 m log collected from the field (between discs 2 and 3) 11. Sawlog Log density: Average density of the 3.9 m sawlog log (between discs 2 and 3) 12. Sawlog log MOE: 3.9 m sawlog MOE calculated using resonance acoustics and density measured on the sawlog 13. Top Log Dia: Large end diameter of a 1.3 m peeler log taken from the top of the 8 m log collected from the field (between discs 3 and 4) 14. Top Log density: Average density of the 1.3 m top log (between discs 3 and 4) 15. Top log MOE: Top log MOE: 1.3 m top log MOE calculated using resonance acoustics and density measured on the top log (between discs 3 and 4) 16.
