Thickness assessment and weight modeling of cork in Tunisia: case study of Ain Snoussi forest

Cork stoppers

Estimate reproduction cork thickness as a criterion to examine the commercial value and to fit a non-linear model for predicting cork weight to guide the forest decision makers toward a reasonable harvest.

The objective is to guide forest decision-makers towards a reasonable cork harvest by:

• examining the thickness of cork as a criterion for estimating commercial value

• evaluating the intensity of the debarking operation on the tree

• establishing a non-linear model for predicting cork weight.

Field sampling methods for cork value evaluation before cork debarking

Cork sample (cala) being extracted from a tree.

The objective of the current work is the analysis of alternative sampling methods and intensities for estimating cork value before its extraction (price per unit of weight), considering the trade-off between sampling precision and costs. The dataset includes 30 sampling clusters for each of the 6 stands, where the measurement of the tree coordinates in each plot allowed for the simulation of several sampling methods and intensities, and the comparison of the percent errors and sampling costs.
