The Accidental Introduction Of Invasive Termites Is Increasing Globally
Termites are no doubt beneficial to the environment. In fact, if all termites were to disappear from earth, humans would have a very difficult time surviving, as plant debris would progressively accumulate over soil until the continued growth of vegetation would become impossible. While it can be agreed that termites are good for the world, there is no denying their destructive capacities. The rate of termite destruction around the world is increasing, and this is partly due to a global increase in invasive termite populations. There are several factors that contribute to this increase, and global warming is often mentioned as the primary driver. However, global trade is also a major factor behind the global increase in invasive termite populations, and experts believe that this trend will only intensify in the future.
Several studies have found that subterranean termites in North America are moving northwards. One particular dampwood termite species that used to dwell only in America has now established itself well into Canada. These termites migrate into non-native regions where they can establish an invasive presence. This same trend is occuring in Europe. However, Europeans are blaming the negative trend on relaxed custom checks as opposed to climate change.
Researchers have noted that softwoods exported from Europe and America sometimes contain termites. Native termite populations in foreign lands are often completely destroyed by the invasive termites contained within these imported softwoods. During the past few decades, custom checks have become less strict within the European Union. Back in 1993, shortly after the EU relaxed certain aspects of custom checks, an invasive termite infestation appeared in Devon, England. This was notable, as England does not contain any native or non-native termite species. Although nobody knows how the invasive termites arrived in the country, many people were convinced that they were either wittingly, or unwittingly brought into the country by foreign visitors passing through customs. Invasive termites have been a problem in France for years, and many believe that inadequate custom checks are enabling their entrance into the country. One researcher has predicted that relaxed custom checks in the EU, and not climate change, will be the most significant factor behind future introductions of invasive termites in the union.
Do you believe that lawmakers generally fail to recognize the threat of invasive insects?
