Isn't there a pine tree (Jack pine?) that releases it's seeds after a forest fire. But I think it's because of heat not smoke.

That's true; some plants rely on the heat of a fire for seed activation; others, like some eucalypts, regenerate bark and ditch the superficial layers so as to be fire resistant themselves. There are also some plants in WA called "Black Boys" that sprout ferociously when they are burned.

Mum taught me that with many natives in Australia, bushfire heat is what causes germination of the seeds so you put them in boiling water for a few minutes before planting them e.g. Bottlebrush.
