TERN: Data infrastructure that enables fire management

  1. 1. TERN: Data infrastructure that enables fire management Nikki Thurgate, S. Guru and T. Clancy
  2. 2. TERN: • Infrastructure and networks to support a coordinated, collaborative ecosystem science community • Enabling sustained, long-term collection, storage, synthesis and sharing of ecosystem data • Connecting science with policy and management TERN: Australia’s ecosystem observatory delivering data streams to enable environmental research and management

  5. 5. TERN Fire data- Repeated fuel reduction burns in temperate forests, like this one in southeast Australia, have little long-term impact on soil greenhouse gas exchange

Age-structure in GWW woodlands Age class (years since fire) Percentageofwoodlandarea 0 20 40 60 80 Satellite image analysis 0-60 61+ • Understanding the age structure of GWW woodlands could provide clues as to whether recent levels of woodland fire are unprecedented • To provide a crude assessment of the age structure of woodlands across the GWW, we extrapolated the results from gimlet woodlands and landsat fire mapping to the regional scale, by assuming that the distribution in age classes older than 60 years is proportional to random samples from E. salubris woodlands Area mapped for fire age GWW boundary

  10. 10. Management implications • As diversity was highest in mature woodlands, there is no support for gimlet woodlands requiring recurrent fire to maintain plant diversity, at least within 400+ year timeframes • Intense stand-replacing fires at intervals of < 200 yrs would have adverse implications for biodiversity conservation. Species diversity would not increase to the community maximum Multi-century changes in plant diversity
