These trees are pretty common in the Catskills and make great walking sticks. I also have fond memories of using them as catapaults in my childhood. When young, they are very flexible and springy. Bent back, one a couple inches in diameter and can propel a small child or large ball a considerable distance. I taught this skill to my nephew, much to my sister's annoyance, and at eight or nine he once launched himself so far away that he got lost for a couple of hours. : )

A small, mostly Northern tree with green bark vertically marked with thin white stripes.

Grows best in semi-shade, damp conditions.

Not very useful as a hardwood for construction or furniture. It just does not get big enough for commercial value.

This tree typically grows as an understory tree in wooded areas. It has bright green leaves in summer. Fall foliage is a beautiful bright yellow. Shady conditions are essential. It is intolerant of pollution, drought and heat.

This common tree is easily distinguished from other trees, with lobed leaves growing in pairs. Maples also have distinctive fruits called samaras-winged, paired seeds that spin to the ground like helicopter propellers.

What to look for: Leaves 3 lobed and finely toothed and pale below. Flowers are bright yellow on long hanging stalks. Bark is smooth and bright green with white stripes.

Habitat: Up lands and rich moist soil.

Size: 20 - 30 feet tall. Leaves 5 - 6 inches long.
