Publication Open Access Fire in the woods or fire in the boiler: implementing rural district heating to reduce wildfire risks in the forest-urban interface(Elsevier, 2015) Blanco Vaca, Juan Antonio; Dubois, David; Littlejohn, Dale; Flanders, David N.; Robinson, Peter; Moshofsky, Molly; Welham, Clive; Ciencias del Medio Natural; Natura Ingurunearen ZientziakMany rural communities in British Columbia (western Canada) are at risk from wildfire. This risk will increase over time as a result of climate change because of higher average temperatures, longer growing seasons, and more intense droughts. On the other hand, these communities are also faced with rising fuel costs and a growing demand for heat as suburban population increases. The fact these communities are surrounded by forests presents an opportunity to combine community wildfire risk abatement with bioenergy development. Additional co-benefits include: 1) reduced community energy expenditures; 2) the creation of local jobs; 3) climate change mitigation; and 3) increased community energy security. Here, we present results from three pilot rural communities (Burns Lake, Invermere, and Sicamous, British Columbia) designed to evaluate the feasibility of wildfire risk abatement in conjunction with bioenergy production. Maps were created showing each community’s forest-urban interface area with quantified estimates of its sustainable woody biomass resource potential under different management scenarios while monitoring ecosystem and soil health. The results and experience gained through this work has been synthesized in a calculator tool to help other communities make their own screening-level assessments. This calculator is a freely available on-line tool: FIRST Heat.Publication Open Access Soil organic matter: a sustainability indicator for wildfire control and bioenergy production in the urban/forest interface.(The Soil Science Society of America, Inc., 2014) Blanco Vaca, Juan Antonio; Dubois, David; Littlejohn, Dale; Flanders, David N.; Robinson, Peter; Moshofsky, Molly; Welham, Clive; Ciencias del Medio Natural; Natura Ingurunearen ZientziakMany rural communities in British Columbia (western Canada) are increasingly at risk from wildfire as temperatures rise and droughts become more frequent. In addition, these communities are also faced with rising fuel costs, and a growing demand for heat as their populations increase. The fact these communities are surrounded by forests presents an opportunity to combine community wildfire risk abatement with bioenergy development. Here we show how the ecological model FORECAST was linked with GIS and economic models to create a freely available on-line tool (FIRST Heat) to help other communities make their own screening-level ecological assessments of combining wildfire risk control with district heating systems. The tool incorporates an ecological sustainability index based on the relative change in soil organic matter (SOM) after 50 years of management compared to initial levels. Two thresholds were defined: 10% SOM lost as “warning” level, and 20% SOM lost as “critical” level. The tool was able to adequately capture the influences of ecological zone, stand age, site quality, and intensity of forest management on SOM losses. Stands in the sub-boreal and arid interior were significantly more exposed to SOM losses than in other ecological zones, as well as soils in old-growth forests. Stands in poor sites were significantly more sensitive to forest management than young and fertile sites. All things considered, our results show the suitability of incorporating ecological models and SOM thresholds in user-friendly decision-support tools to successfully transfer scientific knowledge on forest soils to local stakeholders and decision makers.
