Invasive"fire steppe" in Arizona?

Re the recent discussions on change, invasives et al, the Alpha Environmentalist sends this link from the Arizona Daily Star on how non- native, fire resistant species have created a dangerous environment for such natives as the green- barked paloverde and the iconic saguaro cactus. Neither can survive burning, while the non- native steppe plants can. And a lot of birds, reptiles, bats and more depend on the plants of this unique "xeric forest".

Not mentioned in the article are the thousands of trophy houses going up in this unsuitable ecosystem, and how a "permanent burn" steppe might affect their real estate values. Ill winds... may be blowing.
