The infestation of Douglas-fir bark beetles that took over 90 hectares of forest just outside Nelson is a sign of what one local expert calls an impending provincial catastrophe.

Gerald Cordeiro, a forest development manager with Kalesnikoff Lumber, first alerted Nelson city council to the infestation . On Monday he returned to say the infestation had been mostly been removed, but the entire region is vulnerable.

含羞草研究社淚 don含羞草研究社檛 think it含羞草研究社檚 an exaggeration to call it a crisis,含羞草研究社� said Cordeiro. 含羞草研究社淚t含羞草研究社檚 not on the scale of the mountain pine beetle, but fir forests are generally not on the scale of pine forests in B.C., or what we used to have as a pine forest.

含羞草研究社淲e have some really heavily fir-dominated forests [in the Kootenays], especially on our south and west aspects. We含羞草研究社檙e going to see some pretty devastating effects.含羞草研究社�

Cordeiro said a cutting permit was granted by the forest ministry to remove infested trees. Trap trees, which are fallen healthy trees, were also used to attract beetles. Those trees were in turn taken to a mill and destroyed along with the beetles inside.

Although the majority of the infestation was removed, Cordeiro said beetles still likely exist at the Ward Creek and Wee Selous Creek sites because those locations were not accessible.

He also warned the infestation could return to Selous Creek, which serves as a secondary water source for Nelson that is used in the summer to support the main source at Five Mile Creek.

含羞草研究社淵ou have to continually monitor it because the bugs are very mobile, they fly. We could reduce to an endemic population in one area and they could fly in from a neighbouring watershed in a very short period of time.含羞草研究社�

Douglas-fir bark beetles kill trees within one to two years, after which the infested wood cannot be salvaged.

A by the provincial government found 78,471 hectares of forest infested by the beetle.

Cordeiro pointed to developing infestations on the North Shore and around Kokaneee Creek, and added some beetles have already been found on private properties within city limits.

含羞草研究社淚 would say it含羞草研究社檚 almost becoming ubiquitous in the fir forests around Nelson.含羞草研究社�

Fire break proposed

As the infestation grows, so too does the possibility of previously green trees becoming more likely to burn.

Cordeiro said Kalesnikoff has begun a planning process in partnership with the Regional District of Central Kootenay that would build an estimated 150-hectare fire break in the Selous Creek area.

含羞草研究社淚t involves a sort of light touch, selective cut to remove the most flammable, most at-risk, what we would call climate change loser trees, unfortunately,含羞草研究社� he said.

含羞草研究社淭hose being cedar and hemlock that carry that really scary Crown fire. So the idea is to reduce the amounts of those trees, open the canopy up a little bit, [and] promote more broad leaf species and brush.含羞草研究社�

Cordeiro added the company will engage in public consultation as part of the planning.

He also said he含羞草研究社檚 exploring how agroecology, which is the study of how ecological processes can be applied to agricultural production, might be used to find new uses for land undergoing fuel mitigation.

As forests are thinned and canopies opened up, Cordeiro said, the space can still be used to provide for societal needs such as food security.

含羞草研究社淚 don含羞草研究社檛 have all the answers right now but I feel the concept is good, that we can get back some other benefits from those forests so we含羞草研究社檙e not just managing them for timber or aesthetics,含羞草研究社� he said.

含羞草研究社淲e含羞草研究社檙e going to be managing them for fire hazard so let含羞草研究社檚 take advantage of whatever opportunity that throws at us.含羞草研究社�
