Not everything is the boogeyman, Matt.

"Eucalyptus oil is highly flammable; ignited trees have been known to explode.[29][30] Bushfires can travel easily through the oil-rich air of the tree crowns.[31][32] Eucalypts obtain long-term fire survivability from their ability to regenerate from epicormic buds situated deep within their thick bark, or from lignotubers,[33] or by producing serotinous fruits.

In seasonally dry climates oaks are often fire-resistant, particularly in open grasslands, as a grass fire is insufficient to ignite the scattered trees. In contrast, a eucalyptus forest tends to promote fire because of the volatile and highly combustible oils produced by the leaves, as well as the production of large amounts of litter high in phenolics, preventing its breakdown by fungi and thus accumulating as large amounts of dry, combustible fuel.[33] Consequently, dense eucalypt plantings may be subject to catastrophic firestorms. In fact, almost thirty years before the Oakland firestorm of 1991, a study of eucalyptus in the area warned that the litter beneath the trees builds up very rapidly and should be regularly monitored and removed.[34] It has been estimated that 70% of the energy released through the combustion of vegetation in the Oakland fire was due to eucalyptus.[35] In a National Park Service study, it was found that the fuel load (in tons per acre) of non-native eucalyptus woods is almost three times as great as native oak woodland.[35]"
