As a wildland firefighter, we use fire to help diversify and strengthen ecosystems. Fire helps fertilize the soil. The heat from the fire also helps propogate certain species of plants, such as conifer trees; their cones are opened and the seeds are dispersed. Depending upon the intensity and duration of the fire, a lot of species may survive. However, if the fire burns long enough and intense enough, trees may be killed and certain grasses will be lost. Fire is also used to kill off non-native species, such as some cedars.

Hi, I'm a farmer in Australia. In my experience, fire generates all sorts of new growth in many or our native species. And quite rapidly too, only a couple of months after a bushfire, lots and lots of new shoots have formed, when just after the fire, all was black. The Aboriginals going back 3000 years ago used to burn off areas of bushland to get this new growth to regenerate, but they were confined to areas, to allow animals to survive and recover after a fire in the un-burnt areas and also it was done in the spring, after winter so that things weren't really dried out after summer when a fire can cause more destruction. The wild life seems to suffer more from a bushfire than the plant life. But of course, a fire that is too hot will destroy anything. And the eucalyptus oil in the trees is quite flammable, so if the fire gets into that, then it will burn the tree out.

If it's one thing plants love, it's fire. They will cackle with joy when you light them up! Especially the pine trees. I think the pine trees love it more because all those needles are always pricking their branches and what not making it very uncomfortable, but the fire solves that problem.
They actually love the fire so much that people have seen some trees taking the fire from others!! I know, it's criminal, but then again, they don't have laws.

that depends on the plant. a giant sequoia tree's seed cannot open without extreme heat, like a forest fire. other plants die from fire, so it all depends on the plant.

Wild blueberries and blackberries grow better right after a fire
because the soil is more acidic
