That certainly seems true of local species if you are talking about adult
plants and not seed germination. During our fire season most local Drosera
are dormant as they are Tuberous Drosera which do best in a cleared area.
Some species flower more rapidly when they emerge after fire, producing
flowers before they produce leaves. Non-tuberous Drosera such as D. binata
manage to re-generate from protected buds or from their roots and are quick
to re-appear after fire. The areas where they are easily found are prone to
fire.
