Essay On Forest Fire Regenerates The Ecology

Obviously plants can’t move away when a fire comes through an area, so how are they able to survive and persist?Most vegetative survival involves the protection of tissue from heat which would otherwise destroy it.stems Fire acts as a generalist herbivore removing plant material above the ground surface, thus enabling new herbaceous growth.Above ground re-sprouting: While many trees are killed by total defoliation following a fire, some can re-sprout from epicormic buds, which are buds positioned beneath the bark.Mortality is likely to be higher in flightless invertebrates, and also some insects in vulnerable stages of development (e.g. Dispersal is often an immediate reaction to fire, and it is an important cause of change in the composition of fauna at a site.Indirect effects of fire are related to the alteration of the physical environment.

Think about light availability, changes in nutrient levels, changes in competition, changes in micro-climate, hydrological changes, space, resources and predation pressure.Can you draw a conceptual diagram indicating changes in light penetration and water movement (infiltration and runoff)?Fire alters vegetation structure and composition, and can result in changes in resource availability for fauna.This can lead to These environmental changes then affect faunal populations.For further information, including about cookie settings, please read our Cookie Policy .By continuing to use this site, you consent to the use of cookies.Re-sprouting resprouts after a fire Root suckering can result in large clonal populations post-fire.Other plants have woody swellings at the base of their stems called lignotubers. (1976) Observations on the ecological significance of vegetation reproduction in the Katherine-Darwin region of the Northern Territory.They contain latent buds which are released from dormancy post-fire. Geophytes survive burning because the storage organs are below ground protected from burning. Look at the pictures below (pre- and post- fire in same habitat).They persist vegetatively between fires, and are stimulated to flower following a fire. What kind of changes do you think that there might be to the environment post-fire?
