There are over 700 species of trees, shrubs, flowers, grasses and ferns on Open Space and Mountain Parks (OSMP). Many of the plants migrated to the area when the climate was quite different; others have evolved in this area, and some have been either accidentally or purposefully introduced by people since 1858. This has resulted in a tremendously diverse spectrum of plant species, including those common to the Great Plains tallgrass prairies as well as the Southern Rocky Mountains. Such Ice Age relicts as paper birch trees and Black Snakeroot can be found on OSMP, as well as a number of critical plant species of special concern.
BE CAREFUL! Poison Ivy grows in many places throughout Open Space and Mountain Parks, especially in moist drainages. Watch out for three shiny leaves.
