Bob Gray thinks we need more forest fires in B.C. 91裸聊视频� fires that are prescribed, planned, and large.

91裸聊视频淭hat91裸聊视频檚 the only way to create barriers to wildfires,91裸聊视频� he said, adding up to 40 per cent of B.C.91裸聊视频檚 forests should be barriers to wildfires, not fuel for them.

He says whenever we harvest, the harvest area should then be burned.

91裸聊视频淣ow a lot of our harvests, they do not function as fire breaks. They speed up the fire. We harvest and we don91裸聊视频檛 treat the slash. Everything we do out there does not impede fire flow.91裸聊视频�

Gray will present these and other ideas at , a running Tuesday through Thursday this week in Nelson, featuring a variety of local and international speakers from government, industry and academia. He is a fire ecologist and the president of R.W. Gray Consulting Ltd. in Chilliwack.

91裸聊视频淚n the past,91裸聊视频� he said, referring to the time before governments started aggressively suppressing forest fires, 91裸聊视频渁n area that burned in a wildfire would possibly re-burn again once the trees came down and you would have this sort of fuel free situation. And then a forest grows into that, and it functions as a barrier for a long period of time.91裸聊视频�

How does he know it happened this way?

91裸聊视频淲e have old historic aerial photographs and fire history studies using dendochronology (tree ring dating) to determine past fire activity. We actually can develop a good idea of what happened and we run that through simulation models and we calibrate it, and then we can start to simulate those patterns, and then apply future management scenarios to it.91裸聊视频�

He said a lot can be discovered through these methods.

91裸聊视频淲e can look at past fires to see what burned in the perimeter and what burned the hottest and what has not burned at all, and we look for certain patterns and characteristics and we see stands that burned twice and survived wildfire because there is no surface fuel.91裸聊视频�

Fires in the past weren91裸聊视频檛 as big as they often are today, he said.

91裸聊视频淲e did not have these 500,000 hectare fires, at least not very often, and so we are trying to see what that pattern and process was on the landscape, and what were those stand types were that functioned as barriers to fire and how can we recreate those practices.91裸聊视频�

He said B.C. needs burning programs that have long term dedicated funding, not small short-term projects.

91裸聊视频淲e need programs situated in each fire zone with a combination of wildfire service crews and industry people 91裸聊视频� we need to have people trained up and qualified. You give them five years worth of funding and you make a schedule, what you are going to burn every year, and you have plans written out ahead of time and review and retrain. It is like a fire department.91裸聊视频�

Gray is also known for his opinions about B.C.91裸聊视频檚 funding for wildfire prevention versus earthquake preparation.

He says over the past 10 years fighting wildfires in B.C. has cost tens of billions of dollars, yet governments have invested about $100 million in mitigation. He says the ratio is about two per cent. But with seismic upgrading it91裸聊视频檚 a different story.

91裸聊视频淭he interesting thing is, if we look at flood mitigation and seismic mitigation we see that the funding is almost 1 to 1.91裸聊视频�
