Not made up, Sybil.
Are eucalyptus trees the cause of the CA fires?

Not really. It's the brush that isn't clear away.

Yes they are made up. You have not proved them true.

I don't need to prove history, Sybil. You just want to deny it.

Thanks for confessions.
Perhaps you'll need to direct your confessions to this:

Assumption of victory fallacy. That won't work, Sybil.

Are Eucalyptus Trees Flammable?
Eucalyptus trees are widespread in California and have been introduced to many other warm states. In California, the trees have spread so prolifically that there are entire woodlands almost completely made up of gum trees. Efforts are underway to eradicate the introduced species and return woodlands to their native species. This is because the eucalyptus has displaced natives and it changes soil composition where it grows, altering other life forms as it does so. Eucalyptus fire hazards are also cited in efforts to remove the trees. There are some native eucalypti, but the majority have been introduced. These hardy plants have delightfully scented, volatile oil in all parts of the plant. The tree sheds bark and dead leaves, which make a perfect pile of tinder under the tree too. When the oils in the tree heat up, the plant releases flammable gas, which ignites into a fireball. This accelerates the eucalyptus fire hazards in a region and discourages firefighting efforts. Removal of the trees has been recommended largely due to eucalyptus fire damage but also because they are taking the place of native species. The plants are considered dangerous in fire-prone areas because of their habit of shooting sparks if they catch fire. Eucalyptus oil and fire are a match made in heaven from the fire’s perspective but a nightmare for those of us in its path.
Eucalyptus Fire Hazards: Are Eucalyptus Trees Flammable
Are eucalyptus trees flammable? In a nutshell, yes. These beautiful stately trees are filled with aromatic oil, which makes them highly combustible. Learn more about the fire hazards of eucalyptus trees in this article.

The self-heating and ignition of vegetation debris
Abstract
Leaves of the tree Eucalyptus saligna were examined for their propensity to self-heating and spontaneous combustion. The method used was basket heating and application of thermal ignition theory. Similar work was carried out on wood shavings. The leaves were shown to be a possible ignition hazard in practical situations, the wood shavings less so. Agreement of the results with the predictions of thermal theory was satisfactory.
A Review of Leaf-Level Flammability Traits in Eucalypt Trees
Abstract
With more frequent and intense fires expected under future climate conditions, it is important to understand the mechanisms that control flammability in Australian forests. We followed a systematic review approach to determine which physical traits make eucalypts leaves more or less flammable. Specifically, we reviewed 20 studies that covered 35 eucalypt species across five countries and found that leaf water content, leaf area (LA), and specific leaf area (SLA) are the main drivers of leaf flammability. These traits are easy and straightforward to measure, while more laborious traits (e.g., volatile organic compounds and structural carbohydrates) are seldom measured and reported. Leaf flammability also varies with species, and, while the biochemistry plays a role in how leaves burn, it plays a minor role in fire behaviour at landscape scales. This review highlights the range of different protocols used to measure flammability and leaf water content, warranting caution when comparing traits and results between studies. As a result, we propose a standardised protocol to measure leaf water content and advocate for long-term measurements of leaf traits and flammability. This study not only contributes to the understanding of how and why eucalypt leaves burn but also encourages research into the relative importance of traits in influencing flammability and provides a guide for selecting traits that can be monitored using satellite images to inform fire management policies and strategies.

So eucalyptus trees burn easily. Several species of trees do. Meh.
Clean up the brush so fire doesn't get into them, do something about your arsonists, and build water reservoirs and adequate power generating systems.

Heat. Eucalypt exudes flammable gas. Dry . Oil-filled eucalypt detritus internally combusts. Gas ignites. Bush-fire.
