I actually worked on some Callitris years ago for Val LaMarche’s S hemisphere project. I’ll look that old one up, I need more from the south for Oldlist!
Hi Pauline, excellent question, and no we did not consider those at all. I’ve not included any in my Oldlist, mainly due to questions of dating continuity of genets between living and remnants. But a ripe area of study for sure!
Thanks Steve! I do need to modernize the list someday soon…

At the root of all our problems stands one travesty: politicians’ surrender to the super-rich | George Monbiot

The dramatic images from wildfires tearing through Spain and Portugal year after year have become a mainstay of Europe’s increasingly blistering summers.
But experts say that most of the damage is, in fact, preventable — if only authorities at regional, national and European levels would act.

Wildfires are preventable. So why does the Iberian Peninsula keep burning?
Governments can’t use climate change as an excuse for failing to take preventive measures, scientists say.

Good article, but wildfire is never “preventable”; all of the management strategies outlined will never stop wildfire from burning at some point, but will “mitigate” severe effects and damage to human infrastructure. But fire itself is inevitable in these ecosystems; best accept that fact.

The Turkeyfeather Fire in the Gila Wilderness, NM has burned as a low-severity fire over about 24,000 acres (so far). This is a continuation of a fire regime that existed for millennia before the 20th century. This 🧵reviews the fire history of the Gila, as my colleagues and I have studied it. 1/18
