Because infected snakes seem to be able to spread the fungus to new snakes or new habitats, you decide to cull infected snakes found in the wild to reduce further spread as much as possible. The humanpower required to seek out snakes across the state makes this an expensive and time-consuming intervention, and even after all that hard work, you estimate that you were only able to cull 30% of infected snakes. You can do this intervention again later if you have enough resources. In NetLogo, click the “cull-infected-snakes” button a single time, which should cause many of the red dots to turn black temporarily. Now advance 6 weeks/ticks and subtract $100,000 from your budget. What would you like to do next?
