The hills around Bellingen could burn for a year...


NSW Forestry Corporation will log, bulldoze and burn Tarkeeth State Forest. “Residents have been told by Forestry Corporation that waste vegetation would be bulldozed into windrows and burnt over a period of a year or more...Imagine the smoke pollution right across the Valley." (source)

Study indicates 'biomass burning' may play larger role in climate change than previously realized. "Based on aircraft observations, satellite data and models, the findings indicate 'biomass burning' may need to be addressed with future regulations. Following closely after COP21, the results could suggest a need to look at other sources of greenhouse gas emissions, in addition to industrial activities and fossil fuel combustion in industrialized nations."

Smoke - "Globally around 340,000 deaths per year are thought to be attributable to the additional pollution from landscape fires. Ending deforestation by burning would have many benefits, not only for global climate and biodiversity but for human health too." (source)

The Control of Fire by Birds



Early humans are seen as inventors of fire technology. Now birds of prey such as the the Brown Falcon (Falco berigora) and the Black Kite (Milvus migrans) join the list of those propagating fires deliberately in the Australian savanna woodlands.

Many birds benefit from anthropogenic fires or lightning fires, but narratives of ornithogenic fires have for a long time survived in legends and ceremony in many places around the world.
"Fire provides the opportunity for pyrophilic behaviour by some birds. Brown Falcons, Falco berigora, perch at the fire-front waiting for grasshoppers, frogs, snakes, lizards and small mammals.

Local Aboriginal people believe that Black Kites set fires by carrying burning sticks to new locations and drop them into dry grass on unburnt grounds...I have seen a hawk pick up a smouldering stick in its claws and drop it in a fresh patch of dry grass half a mile away, then wait with its mates for the mad exodus of scorched and frightened rodents and reptiles.

“When that area was burnt out the process was repeated elsewhere. We call these fires Jarulan.”

There is an extensive body of recorded material – some over 100 years old – of Aboriginal myths and legends relating to birds and fire from across Australia." (Source)
