Is a forest that is made up of one type of tree more likely to survive a disease or a forest that has many types of trees?

A forest made up of many types of trees is generally more likely to survive a disease than a forest dominated by a single tree species. This diversity enhances resilience, as different species may have varying levels of resistance to pathogens. In contrast, a monoculture can be more vulnerable to disease outbreaks, as a pathogen that targets that specific species can quickly devastate the entire forest.
