I'm looking for a technical term to describe the study of infestations of invasive species. It seems that "epidemiology" is defined (by WHO) as
the study of the distribution and determinants of health-related states or events (including disease), and the application of this study to the control of diseases and other health problems. Various methods can be used to carry out epidemiological investigations: surveillance and descriptive studies can be used to study distribution; analytical studies are used to study determinants.
But it also seems that this word has a "human disease" component thoroughly baked into it.
Specifically, I am writing a report that concerns an infestation of a specific kind of insect in a forest. Can I say something like "botanical epidemiology"? The insect causes a disease within trees which kills them.
I am just wondering if there is a word specifically for invasive species infestations.
