Washington hosts a fantastic range of plants. This diversity reflects the geography and topography of the state, as well as its geological and biological history. To explore the dramatic diversity of plants in Washington, we look across the state to specific places that differ in topography and climate to find a range of plant communities. These are groups of plants that tend to occur together in particular local environments. We first look at the forces that impact plant communities and how communities change over time. This will help to show why we find a range of plant communities and diverse kinds of plants in Washington. In most of this program, we visit specific locations in the state to introduce major plant communities that will help you understand better the environmental diversity of Washington.
