Fire contributes to Earth System Science (ESS).
Fire as a driving factor for ecosystem and biodiversity.
Fire management (Forester);
Fire as land management tool.
FIRE MANAGEMENT cont.
Fire dependent ecosystems,
Fire independent ecosystems,
Fire sensitive ecosystems, and
Fire influenced ecosystems.
Integrated fire management.
Old The Hedgehog Concept.
New The Fox Concept.
Fire independent ecosystems
Fire dependent ecosystems
Fire sensitive ecosystems
Fire influenced ecosystems

TYPES OF FIRE ECOSYSTEMS
South African environmental conditions are complex, not complicated.
Understand the conditions for better management.
Link + Interaction = Functionality
Fires can be beneficial.
E.g. management of the ecosystems.
Fires can also have detrimental effect.
E.g. Destruction of the land.
