WF17058Short-term stem mortality of 10 deciduous broadleaved species following prescribed burning in upland forests of the Southern US

Tara L. Keyser, Virginia L. McDaniel, Robert N. Klein, Dan G. Drees, Jesse A. Burton and Melissa M. Forder

Two years following prescribed fire in upland forests of the Southern US, stem mortality of 10 deciduous broadleaved species ranged from 7 to 59%. Stem size was inversely related to the probability of stem mortality (P(m)) whereas maximum bole char height was positively related to P(m) for all species examined.

WF16221Mapping Canadian wildland fire interface areas

Lynn M. Johnston and Mike D. Flannigan

This study defined and mapped the interface areas of Canada. The wildland–urban interface was found to cover 32.3 million ha (3.8% of total national land area). Two novel interface types were also mapped: the wildland–industrial interface (10.5 million ha; 1.2% of land area), and the infrastructure interface (109.8 million ha; 13.0% of land area).


Simulation modelling showed that an unrealistically large-scale prescribed-burning program across Tasmania would be necessary to reduce wildfire extent and intensity under dangerous fire-weather conditions. By contrast, more feasible, but geographically constrained, broad-scale prescribed-burning plans had substantially reduced effects on area burnt and fire intensity. This study highlights the need for targeted localised fuel treatments rather than broad-scale prescribed burning.
