Grape phylloxera spread model

Dataset

Description

A model was developed to simulate the movement of phylloxera through a vineyard block(s).

The below code simulates phylloxera spread through two blocks that contain all preferred soil.
PhylloxeraSpreadModel_AllPrefSoil.R

We also assessed the influence of soil type (preferred/nonpreferred) on phylloxera spread in the code below.
PhylloxeraSpreadModel_PrefNonprefSoil.R

Next, multiple surveillance strategies were developed that either used the standard surveillance strategies or variations to it (PhylloxeraSpread_StandardSurveillanceVariations.R) or a surveillance strategies that targeted soil types (PhylloxeraSpread_TargtedSurveillanceVariations.R).

These surveillance strategies were overlaid on the spread simulations (output from spread model) to determine the time to detection and total spread of phylloxera.
