Overview: Clear-Cuts, Washington State, p. 260

This area has almost all been harvested at one time or another. The gray areas are recent clear-cuts. Light green patches have been replanted and have young forests. Darker green areas are older forests. If you zoom in on them, you can see roads and staging areas left from the last harvest. A few small patches of tall trees remain.

1
Would you say that clear-cuts cover a significant or an insignificant proportion of the landscape in this area?
A)Clear-cuts are generally insignificant in this area.
B)Occasional clear-cuts can be found here, in various stages of reforestation.
C)At least half the landscape appears to be farms, surrounded by forests with occasional indications of clear-cuts sprinkled about.
D)Clear-cuts checker most of the landscape in any direction except south, where the land is mostly converted to agriculture.
E)Clear-cuts checker most of the landscape in any direction except north, where the land is mostly converted to agriculture.
2
A network of streams can be seen just to the north of this place marker. How much tree cover is left in the riparian zone along these streams?
A)The trees have been stripped completely from the riparian zone.
B)The riparian zone is a very thin row of trees.
C)The riparian zone is bordered by a strip of trees more than ten thick.
D)The riparian zone is bordered by a thick zone of old growth forest.
E)It's hard to discern where the riparian zone ends and the forest begins.
3
Zoom out slightly and move northwest, north, or northeast of the place marker. How many areas of unbroken forest do you find?
A)Unbroken forest is very hard to find in this region.
B)Unbroken forest is spotty in this region.
C)Unbroken forest covers roughly half of the region.
D)There are extensive areas of unbroken forest.
E)Most of the landscape is unbroken forest.
4
Peruse the place markers provided for Oregon and Alberta. If you like, also search other areas of these states and provinces, as well as in British Columbia. If you were looking for habitat for Northern Spotted Owls, a species which prefers large tracts of intact, old-growth forest, would it be easy to find suitable areas?
A)It would be easy, because old-growth forest covers most of this region.
B)It would be fairly easy, because there are still large tracts of old-growth forest remaining.
C)It could be done because almost half of the forest remains old-growth.
D)It would be fairly hard, although a few large patches of old-growth forest remain.
E)It would be quite difficult because there is almost no extensive old-growth forest remaining in this region.
