Such adaptations include physical protection against heat, increased growth after a fire event, and flammable materials that encourage fire and may eliminate competition. For example, plants of the genus Eucalyptus contain flammable oils that encourage fire and hard sclerophyll leaves to resist heat and drought, ensuring their dominance over ...
Pyrophytes are plants which have adapted to tolerate fire.. Fire acts favourably for some species. "Passive pyrophytes" resist the effects of fire, particularly when it passes over quickly, and hence can out-compete less resistant plants, which are damaged.
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 ...
In response to forest fires, the trees have developed various adaptations. The thick, fibrous bark of coast redwoods is extremely fire-resistant; it grows to at least a foot thick and protects mature trees from fire damage. [55] [56] In addition, the redwoods contain little flammable pitch or resin. [56]
The fire interval is the number of years between fires and is highly dependent on spatial scales. Fire rotation is a measure of the amount of fire in a landscape (the amount of time required to burn an area the size of the study area). The fire rotation statistic is best used for large areas that have mapped historic fire events. [6]
All the Australian sclerophyllous communities are liable to be burnt with varying frequencies and many of the woody plants of these woodlands have developed adaptations to survive and minimise the effects of fire. [23] Sclerophyllous plants generally resist dry conditions well, making them successful in areas of seasonally variable rainfall.
Fire exclusion has resulted in a declining reproductive output, and thus population size, of some species of pyrogenic plants. [3] Additionally, evidence suggests that fires that occur outside of normal seasonal burn times (typically summer months) can have negative repercussions on pyrogenic flowering plants, including lower flowering and seed production when compared to fire-exposed plants ...
Rudyard Kipling wrote, "The fire-weed glows in the centre of the drive ways". [29] In The Fellowship of the Ring (1954), J. R. R. Tolkien lists fireweed as one of the flowering plants returning to the site of a bonfire inside the Old Forest. [30] As the first plant to colonise waste ground, fireweed is often mentioned in postwar British literature.
