Why Problematic Termites Are Beneficial In Times Of Drought
Just about everyone is well aware of the fact that termites inflict significant damage to timber-framed structures, but fewer people are aware of the fact that termites consume wood in order to secure the nutritious cellulose that makes up all forms of plant material. Therefore, termites can also consume smaller wooden items, the paper in books or even champagne corks. Termite damage to structural wood is almost always inflicted by subterranean termites, while both dampwood and drywood termites are the most frequent culprits behind infestations found in smaller objects containing cellulose. Pest control professionals encounter subterranean termite infestations in structural wood far more often than they encounter drywood or dampwood infestations in smaller wooden objects. Subterranean termite damage to structures accounts for a majority of the economic costs of termite damage, which is around 5 billion dollars per year. While subterranean termites may be one of the most economically devastating insect pests that exist, they may also mitigate the negative effects of long-running droughts.
Scientists have long known that termites play an essential role in the health of the ecosystem, as they aerate soil with their subterranean tunneling activity and convert dead plant matter to fertile soil. But now, scientists have found evidence that termites allow soil to retain significant levels of moisture during times of drought. In a large forested area, researchers compared the moisture levels in soil that had been inhabited by subterranean termites with soil that had been free of termites. When droughts did not occur, moisture levels in each area of land remained the same, but during a 20 year drought, termite-inhabited soil retained enough moisture to allow for plant growth. Considering this finding, subterranean termites, although harmful to structures, can maintain a soil fertility during even the most significant of drought periods, thus allowing for the survival of economically valuable cropland.
Considering the above described study, do you believe that subterranean termite activity in crop-soil could be of benefit during dry spells?
