content: Normally true, but not true in cases where there are abundant invasive plant species. See it in California all the time. When the native forest is in tact the exotic invaders can't get a real foothold, but after the fire they have no competition and they run roughshod over the native plants. If there was a such thing as nigger plants, that would be a lot of the invasive weeds. They sprout the instant the first rains fall and they suck up all the moisture from the ground trying to grow and multiply as fast as possible. The indigenous plants are more slow to sprout because they evolved not to sprout at the first rain, which could be the last for some time. Instead, they wait until the ground is good and wet from a few rains. They're like the white guy who plans his winter firewood stash and the nigger weeds come and steal it.
