Mother Nature : she can be so predictable, and its her reliable rhythms that we’ve come to depend upon and even appreciate. Organisms living and working together in ecosystems, cycling energy, recycling nutrients, cleaning the air and water, keeping things moving at the right pace so that there’s no build-up of waste. When these systems are working seamlessly and in sync, we simply notice is the beauty of nature, but when some thing throws the systems out of balance, that’s when we sit up and take notice. All too often, humans are the “thing” that threw mother nature out of balance, and it’s not until the damage is widespread do we realize the impacts of our actions. Today’s post is about just that sort of situation.
Bark beetles encompass a number of different beetle species that share similar life cycle characteristics, mainly that they all lay their eggs under the bark of different coniferous trees. As I’ll explain below, beetle activity can damage and kill trees. This often happens at a slow rate and is actually beneficial to forests: weak trees are killed, making space for healthy, young trees to grow. The “problem” occurs when bark beetle activity is happening so fast and so intensely that wide swaths of relatively healthy trees are also killed.
