What's That Tree?

Identifying the trees on your forestland

Travelling across the state, you would soon discover that Oregon is home to a wide range of trees. There are 30 native coniferous species and 37 native species of broadleaf trees. Oregon varies greatly in terms of elevation, temperature, wind, rainfall and soil composition. Combinations of all these factors help determine the dominant tree species of an area.
