Cephalotus: Another Example of a Pioneer Plant

Cephalotus in the wild

I think one of the neatest things about carnivorous plants is how many are pioneer species. I've discussed and provided some evidence that Sarracenia purpurea and Drosera intermedia and rotundifolia are pioneer species (and here) in New England bogs, and mentioned the same for Pinguicula casabitoana, but I never really considered whether Cephalotus was a pioneer species. It was just so different. Turns out, it is a pioneer species, too.

Bushfire in the Tilley Swamp Conservation Area

In this month's Carnivorous Plant Newsletter, Richard Nunn argues that Cephalotus is a pioneer species in the sense that it is among the first species to reemerge after the swamps in which it lives are burned in bushfires. The life cycle of a Cephalotus plant, then, is to grow in a fairly cleared out area of swamp, get surrounded by larger, competing grasses and other vegetation, and subsist largely on its small, non-carnivorous leaves and fleshy rhizome until a bushfire burns through the swamp, at which time the plant begins rapidly producing pitchers to acquire more nutrients to grow its rhizome in advance of being crowded again. 

Thus, Cephalotus is a lot like Sarracenia in Gulf Coast savannas in that it colonizes open peat lands before being crowded out by other species. The ability to retake or retain hold on its habitat depends, in large part, on whether a fire burns through the area and leaves it open enough for the carnivores to retain dominance.
