Update: 64 death and more than 200 injured people.

There is more than one factor influencing this. I wish eucalyptus was the only cause. It's true that we have a lot of Eucalyptus. Way more than would be expected regarding the territory suitability for other species.
Eucalyptus is more flamable than our native species, for sure, and that is a problem in case of fire. However, I'd say the presence of eucalyptus is probably a bigger problem for biodiversity.
It what wildfires are concerned, the professionally managed exploitations do not burn that much, even if they have plenty of eucalyputs. This should ring a bell. (They have money enough to invest in prevention and even have professional firefighters working for them.)

Concerning native species:
Portugal is known for being the worlds' biggest cork producer. In fact, Cork oak (and the also important Holm oak) are dying like never before. There is a fungus, there is an insect, there are droughts. All of this is true. But the places with less mortality and with more regeneration are in professionally managed exploitations. This should ring the same bell as before :)
