Interesting. Wikipedia [1] also says that these biomes are supposed to have canopy fires rather than smaller burns. I'm a bit skeptical (seems awefully convenient), but it looks like the 500 year climate record supports this idea [2].

If this is the case, then homes in this biome need to be engineered to survive nearby canopy fires every few generations.
