The aim is to monitor the population densities of the lepidopteran defoliator Lymantria dispar in Sardinian oak woodlands. This is done through egg mass counts with the aim of predicting the areas at risk of defoliation and plan insecticide applications accordingly.
Case studies tagged with sampling methods
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.
