Chapter 29 Home Range Contamination Model

IN WAREHOUSE DEVELOPMENT

29.1 What is the Home Range Contamination Model?

The Home Range Contamination Model leverages a Bayesian Hierarchical Model to determine which home ranges are likely to harbor CWD positive hosts.

29.2 What Questions Does it Answer?

Question 1. Where should I cull hosts to have the highest chance of removing CWD positive animals? The predicts risk by age/sex segment, allowing for data-driven, targeted culling operations.

29.3 Output Details

A map that shows risk by home range and age/sex segment.

29.4 Abbreviated Tutorial

  1. Run the model in the CWD Data Warehouse.
  2. Explore the model logs, input file, and output files used in the run.
  3. If the model did not run, check the model logs to understand required data that was missing.
  4. Click through the outputs to compare and contrast the efficacy of various familiar management strategies in attenuating disease outbreak.

29.5 Parameters Needed to Execute the Model

  • Model type: Select ‘Home Range Contamination Model’ from the drop-down list.

  • Reference name: Label the run.

  • (Optional) Applicable season-year: Label the season-year of the run to assist in documentation.

  • (Optional) Notes: Enter any remarks about the run.

  • Season-year: Select the season-year to be used in the simulation.
