Harrington, J.B., Flannigan, M.D.
Long dry spells (sequences of dry days) are rare events, but they are important because they correlate significantly with the area burned during bad wildfire years. Previous attempts to model the frequency of dry spells have been successful for spells of short duration, but have failed for...

A study of the relation of meteorological variables to monthly provincial area burned by wildfire in Canada 1953-80
Download1988
Harrington, J.B., Flannigan, M.D.
The relation between meteorological variables and the monthly area burned by wildfire from May to August 1953-80 in nine Canadian \"provinces\" was investigated. A purely statistical approach to estimating the monthly provincial area burned, using meteorological variables as predictors, succeeded...

Assisted migration to address climate change: recommendations for aspen reforestation in western Canada
Download2011
Mbogga, M. S., Chen, P., Gray, L. K., Gylander, T., Hamann, A.
Abstract: Human-aided movement of species populations in large-scale reforestation programs could be a potent and cost-effective climate change adaptation strategy. Such large-scale management interventions, however, tend to entail the risks of unintended consequences, and we propose that three...

Spittlehouse, D.L., Hamann, A., Murdock, T.Q., Wang, T.
This study addresses the need to provide comprehensive historical climate data and climate change projections at a scale suitable for, and readily accessible to, researchers and resource managers. This database for western North America (WNA) includes over 20 000 surfaces of monthly, seasonal,...

Ecological controls on net ecosystem productivity of a mesic arctic tundra under current and future climates
Download2011
Dimitrov, D. D., Grant, R. F., Lafleur, P. M., Humphreys, E. R.
Abstract: Changes in arctic C stocks with climate are thought to be caused by rising net primary productivity (NPP) during longer and warmer growing seasons, offset by rising heterotrophic respiration (Rh) in warmer and deeper soil active layers. In this study, we used the process model ecosys to...

Fire regimes at the transition between mixedwood and coniferous boreal forest in northwestern Quebec.
Download2004
Flannigan, M., Kafka, V., Gauthier, S., Bergeron, Y.
Fire history was reconstructed for an area of 15 000 km2 located in the transition zone between the mixed and coniferous forests in Quebec's southern boreal forest. We used aerial photographs, archives, and dendroecological data (315 sites) to reconstruct a stand initiation map for the area. The...

Impacts of climate change from 2000 to 2050 on wildfire activity and carbonaceous aerosol concentrations in the western United States
Download2009
Mickley, L.J., Westerling, A.L., Logan, J.A., Hudman, R.C., Flannigan, M.D., Spracklen, D.V., Yevich, R.
We investigate the impact of climate change on wildfire activity and carbonaceous aerosol concentrations in the western United States. We regress observed area burned onto observed meteorological fields and fire indices from the Canadian Fire Weather Index system and find that May-October mean...

Hamann, A., Woods, A., Coates, D.
Dothistroma needle blight, caused by the fungus Dothistroma septosporum, is a major past of pine plantations in the Southern Hemisphere, where both the host and the pathogen have been introduced. In northern temperate forests where the pest and host trees are native, damage levels have...

Shabber, A., Logan, K., Flannigan, M.D., Skinner, W.R.
Relationships between variations in peak Canadian forest fire season (JJA) severity and previous winter (DJF) global sea surface temperature (SST) variations are examined for the period 1953 to 1999. Coupled modes of variability between the seasonal severity rating (SSR) index and the previous...

A Large Fire Database (LFDB), which includes information on fire location, start date, final size, cause, and suppression action, has been developed for all fires larger than 200 ha in area for Canada for the 1959-1997 period. The LFDB represents only 3.1% of the total number of Canadian fires...
