These are the types of worries I have….

Hi again,

The things that I find troubling to do with climate change are when due to the temperature, the natural environmental balance is affected.

For example: The recent warmer than usual temperatures have allowed for higher than  usual survival rate for these long-horn beetles. These beetles, which are native to Asia, have been in the news for some time now, since 1996, and the fact that they are a non-native species is another problem all together. Normally, these beetles will freeze and die during the winter months, and only the ones with the highest fitness survive to eat trees as per usual. This reduces the size of infestation, and thereby keeping the problem the beetles cause small/ manageable.

These beetles are a problem because when the adult beetles colonize a tree, they chew sites in the bark in order to lay eggs on the branches, trunk and root flare. In its early stage, the larva feed in the sappy, green inner bark. Eventually, the larval activity cuts off the transport of nutrients and water. The tree then starts to die from the top down, foliage on the tree wilts and the canopy may appear sparse. As the larva matures, it bores into the sapwood and heartwood, chewing large tunnels which structurally compromise the tree. Feeding by adult beetles also occurs on the leaves of trees, causing significant damage and further weakening the host tree.

I do not mean to sound like Chicken Little, but we are witnessing a huge disaster to our forests, lumber, and maple syrup industries. I am only speaking (blogging) about how until recently, our climate has protected our forests from this invasive species. Because these beetles are non-native species, they have zero natural predators. And according to these articles, and, the very symbol of Canada, the maple tree, is at risk.

I do not know how to stop these many fears associated with climate change, because this long-horned beetle is only one of the many scary things that appear to be getting exponentially worse as our climate continues to change.
