The plants are native to North and Central America, Europe, Asia, and northern Africa. Several species are useful as a source of timber, and a number are cultivated as ornamentals.

The Douglas squirrels are distinguished by their orange colored front teeth that never stop growing. Hence, they constantly control the length of their teeth so that they don't overgrow.
As a result of recent fire history and decades of even-aged forest management, many coniferous forests in western Oregon are composed of young ( yrs), densely stocked Douglas-fir stands. Often these stands are structurally simple - a single canopy layer with one or two overstory tree species - and have a relatively sparse understory.
The lack of structural complexity in these stands may. If Trees Could Talk: Middle School Curriculum “The Greatest Good” Teaching Guide; Lynn W. Day Distinguished Lectureship in Forest and Conservation History.
