Ask a naturalist: Which kinds of trees make which color leaves?

Different tree species are associated with different colors. Hickory and sycamore leaves are golden-orange. Ash leaves tend to be yellow and purple. Oaks hold onto their leaves the longest and produce russet-brown foliage. Sugar maples take on an orange or red tone. There is evidence that red leaves are more prevalent when days are warm, dry and sunny, and the nights are cool (but not freezing). Red foliage has also been linked to fungus and drought.

Bard hosts second annual John Cage Mycology Weekend

Saturday/Sunday, Oct. 19/20: Besides being among the most revolutionary of 20th-century classical composers, John Cage was also an avid amateur mycologist. His interest in mushrooms was literally born out of hunger during the Depression, when he would take the specimens he’d foraged near his home in Carmel, California to the local library to see if they were edible. He spent much of the rest of his life collecting and studying fungi, even supplying upscale New York restaurants such as the Four Seasons with mushrooms he gathered in the local (reachable by subway) wild.
