Sometimes, driving past a place where a beautiful forest was rustling until recently, a person asks himself the question: "What happened?" How is it that mighty trees die in a short period of time, leaving only charred skeletons? Unfortunately, despite the apparent power and greatness, the forest can die for many reasons.
Instructions
Step 1
The most common cause of tree death is forest fires. You have probably seen an advertisement more than once, which calls not to kindle fires in the forest. It appears in May and is broadcast until the fall. And, nevertheless, every weekend, groups of friends, tired of the strenuous workdays, rush out of town. Often they take with them a brazier and alcohol, but not everyone brings a shovel to dig a fireplace. As a result, the fire at the tipsy company gets out of control, and it's good when would-be tourists manage to get away from the fire.
Step 2
Sometimes, in order to start a fire in the forest, it is not even necessary to start a fire. An unextinguished cigarette can cause no less trouble than a fire.
Step 3
However, fires are not only the work of human hands. In hot weather, a fire can occur on its own. The worst is when the peat bogs are on fire. Underground fire can extend for kilometers, destroying everything in its path. The difficulty lies in the fact that burning peat bogs are difficult to extinguish, so this is a real disaster for the forest.
Step 4
It is easy to destroy a forest by disrupting a fragile ecosystem. Often, during deforestation, all old trees are removed, and the young remain untouched. This is done, of course, in order for the forest to recover in a few years - young trees have grown, spread out their crowns, and the new forest appears in all its glory. In fact, it turns out that birds that feed on insects live in old trees. If these trees are cut down, the birds will fly away to a new place, and colonies of bark beetles and other pests will fall on the young, which will be able to feast on young trees with impunity.
Step 5
Climate change, which worries scientists around the world, leads not only to the melting of glaciers, but also to unexpectedly increasing populations of parasites, which, due to the warm summer, manage to give, for example, not three, but five populations. So in 2011, the forests near Moscow were threatened by bark beetles-typographers, whose population increased significantly due to warming.
