Wildfires: record-breaking heat waves in spring and early summer meant fire seasons started Causes, Consequences, and Coexistence earlier with longer, more pronounced summer droughts – our new reality given ongoing climate change and the fundamen- tal links between heat, drought, and wildfire. Not every fire season will break records, but years like 2017 and 2018 will become increas- ingly common over our lifetimes. Importantly, we have learned our mountain forests and the communities within them are not resilient to wildfire and adaptation is urgently needed.4 Wildfire: A Diverse and Complex Force of Nature Understanding wildfire is a necessary first step to ensure adaptation is effective. Wildfire is an essential ecosystem function and evolutionary force that has shaped the ecology of many trees, plants and fauna. The intensity, rate of spread, and behaviour of individual wildfires are determined by weather, topography, and characteristics of the vegetation or fuels that burn. Three general types of wildfires include ground Syringa Creek Wildfire, 2018.

firebreaks, and lower risk of subsequent uncontrollable wildfires. Proactive vegetation management is a surrogate for wildfire closer to communities where we continue to suppress wildfires. In fact, vegetation management is one of the seven pillars of FireSmart – a program designed for all Canadians who live in fire- prone environments (see text box). In the wildland-urban interface, the chance of successfully stopping wildfire increases when hazardous surface and ladder fuels are reduced and the canopy opened by thinning and pruning trees. The resulting forest struc- ture is less likely to conduct crown fire and creates a defensible space to aid firefighters in the case of a wildfire. Therefore, all com- munities surrounded by forests would benefit from proactive management to mitigate fuels, regardless of forest type and degree of disruption to historical fire regimes. Under the right conditions, fire can do more good than harm — prescribed burning is the ultimate example of “fighting fire with fire.”31 Carefully planned and detailed Figure 6 – Transforming from an era BC.28 Given projections of more frequent and Transformative Change: of megafires (left) to coexisting with prescriptions are put into operation only severe fires, the short intervals between fires Learning To Coexist With Fire fire (right).

Last year KFN and the Dan Keyi Renewable Resource Council jointly hosted the Kluane Lake Research Summit to review current and past lake research. The Summit encouraged two-way learning opportunities among dele- gates through presentations, dialogue and activities. The main recommendations from the Summit included engaging in cross-cul- tural learning, developing KFN research protocols and priorities, and the push to further include Traditional Knowledge in research. Another research summit is planned for spring 2019.
