The mountain pine beetle and the Southern pine beetle are native insects, and have natural cycles, bad infestations typically coming several years apart.
We have a bigger problem in this country with insects right now, ones that are imported, which our native trees cannot fight off. The emerald ash borer is devastating populations of ash trees in the northeastern and midwestern states, and it is spreading rapidly, having reached from the East coast to Missouri. Quarantines have not been able to control it so far. It is spreading in firewood that people transport and, to a lesser degree, in wood products made from infected wood. We also have a serious outbreak in the northeast, of the Asian longhorned beetle, which kills several species of hardwoods. And then there's one attacking pine trees that could potentially wipe out the Southern pine zone if it spreads. There are more on the imported insect list that threaten numerous species from coast to coast, including fruit and crops.
My job involves issuing stamps to companies that ship outside the US which show that the wood packaging they use has been treated with heat or fumigant to kill any insects that might be in the wood which could spread to other countries. Our company does monthly audits at these facilities to confirm that they are following the standards. Right now the branch of the USDA that exists to protect our country from such pests is gathering data aimed at setting up a program to require treatment of all wood packaging and firewood products that cross State lines within the US, in what amounts to a last-ditch effort to control the spread of these imported pests, and also to help control the spread of home-grown ones like the mountain pine beetle. Public meetings hosted by the USDA are taking place right now to discuss these problems. I attended the first one, in Wash. D.C. a couple of weeks ago. The second was just held in Houston, TX, and two more are scheduled for Portland, OR, and Grand Rapids, MI.
Our hunting will be impacted by these insects and their effects on our forests for generations to come. Our ash trees, which grow all over the US, might very well go the way of the American chestnut and the American elm, two important species that were devastated by imported pests in our recent past. We have real trouble brewing. It will take the USDA at least two years to get a State-to State program under way, and by that time, if these pests spread at anything like their potential, it may be too late for entire regions of the country.
We can all do our part by NOT transporting firewood from home for any reason. That seems to be the main vector for many of these insects. Dead trees are perfect for firewood, and if an insect killed the tree it is likely still in the wood in larval form. If you're going camping, get your firewood after you get there!
Just imagine scenes like the pictures above, everywhere in the country!
