In winter black locust trees are stark – black, with sharply twisted branches, almost creepy. When flowering, as they are now, they are completely covered with gently drooping, beautiful flowers that almost cover a background of delicate leaves.
About one in a thousand ash trees is able to kill some emerald ash borer larvae and forest geneticists have crossed these rare trees with each other in the hope of finding an ash tree that can kill all the larvae.
Most of us have heard that the CO2 level in Earth’s atmosphere today is higher than it’s been in a million years, but a new study, published in Geology, concludes that there’s now more CO2 than there has been in the past 23 million years. Something to think about while we fan ourselves.
The big damselflies called ebony jewelwing make it hard to walk the brook any faster than at a snail’s pace. The black wings of the males are pretty, but it’s their shining emerald abdomens that stop you in your tracks. They occur in masses here along the top of a new beaver dam.

Not to be confused with damage from the emerald ash borer.
