This was taken yesterday at Fern Cove Nature Preserve on Vashon Island in Puget Sound. A typical forest for the shores of the Puget Sound: mostly the brighter green trees are alder with a few big leaf maples. The evergreens are a mix of Douglas fir, hemlock and western red cedar.
These trees help to keep us cool. One of the factors heating up our area is cutting down the forest and replacing it with grass and pavement. When I was a child (a long time ago) we never saw temps in the 90s (degrees Fahrenheit), let alone days over 100.
