Plants have pathogens. One of the most important for the Ponderosa pine are pine beetles (Dendroctonus ponderosae) that bore into bark to feed on phloem.
The plant responds with a chemical immune system: terpene-rich resin that flows through resin ducts, flushing out or drowning the beetle.

Mountain Pine Beetle - Profile | Invasive Species Centre
The mountain pine beetle is native to western Canada, but has expanded and could become invasive, due to climate change and past forest management programs.
