Autumn Purple Ash (outer leaves are dark purple to bronze in color, while the inner leaves are yellow) and Green Ash are common urban forest trees. The green ash leaves turn yellow in the fall.

Larch or Tamarack Tree - not native to Wyoming; is a deciduous conifer. The larch is in the pine family, but the leaves (feathery groups of fine textured needles) turn yellow and fall off of the tree every fall. "Deciduous" means the tree leaves come off of the tree in the winter to save on water loss in temperate climate trees. "Conifer" means a cone bearing tree. Cone structures are where the tree's seeds develop. There are native conifer species of pine, spruce, fir, and juniper in Wyoming.  Bald Cypress is deciduous conifer, non-native to Wyoming. (Tree located northeast side of E. 23rd St. and Evans Ave.)
