Most unplanned hot fires change the plant composition and reduce growth and carrying capacity in the following season.
The Department of Primary Industries and Regional Development (DPIRD) provides this information to support managers and others suffering from the effects of fire on the farm.
Farmers have asked the questions below after serious fires in the agricultural areas of south-west Western Australia.
Wind and water erosion risk is increased after fire removes groundcover and some seed reserves.
Farm fires will often lead to contaminated surface-water supplies: ash and soil from burnt paddocks and bushland can be blown or washed into farm dams and provide nutrients for bacteria and algae.
Farms in the agricultural areas of south-west Western Australia are particularly susceptible to fire in the hot, dry summer months – accidental and intentionally started fires are not uncommon.
Agistment is an option for removing livestock from a property, for a number of reasons – after a fire, when paddock feed is inadequate, to spell pastures, or to finish livestock for sale on better
Fires can cause significant damage to bush on farms and may devastate revegetation areas.
Following a fire that removes paddock ground cover, the risk of water erosion is greatly increased.
Western Australia's climate has changed over the last century, particularly over the last 50 years. Average temperature has risen about 1°C.
