Both plants and animals have multiple strategies for surviving and reproducing after fire. Plants in wildfire-prone ecosystems often survive through adaptations to their local fire regime. Such adaptations include physical protection against heat, increased growth after a fire event, and flammable materials that encourage fire and may eliminate ...
A 2020 meta-analysis found that while 39% of vascular plant species were likely threatened with extinction, only 4.1% of this figure could be attributed to climate change, with land use change activities predominating. However, the researchers suggested that this may be more representative of the slower pace of research on effects of climate ...
Plants have evolved many adaptations to cope with fire. Of these adaptations, one of the best-known is likely pyriscence, where maturation and release of seeds is triggered, in whole or in part, by fire or smoke; this behaviour is often erroneously called serotiny, although this term truly denotes the much broader category of seed release ...
Since even non-serotinous cones and woody fruits can provide protection from the heat of fire, [6] [7] the key adaptation of fire-induced serotiny is seed storage in a canopy seed bank, which can be released by fire. [8] The fire-release mechanism is commonly a resin that seals the fruit or cone scales shut, but which melts when heated.

In contrast, fire will occur less frequently and less severely in closed canopy forests because the fuels are more dense, shaded, and therefore more humid thereby not igniting as easily. The closed canopy of the dominant forest vegetation will also limit the growth of certain species, and permit the growth of shade-tolerant plants.
NASA imagery showing the interrelatedness of climate and fire. Active fires are represented by red dots. [14] Climate change has affected fire regimes globally, with models projecting higher fire frequencies and reduced plant growth as a result of warmer, drier climates. This is predicted to affect fire-intolerant woody species in particular by ...
The passage of fire, by increasing temperature and releasing smoke, is necessary to raise seeds dormancy of pyrophile plants such as Cistus and Byblis an Australian passive carnivorous plant. Imperata cylindrica is a plant of Papua New Guinea. Even green, it ignites easily and causes fires on the hills.
