This
is the Puget Sound!
|
|
|
|
| Home to many cities (Seattle for example), over 7
million people and our forest (look
for the blue star between Bremerton and Seattle on the map). |
|
|
|
| We will be looking closer at the area highlighted
on the map on the right. |

| These are
satellite images of forest cover from 1972, 1986 and 1996. The blacker
the area the fewer the trees. If you know the area you will also notice
Mount Rainer's glaciers showing up in the bottom right. A bit north of
Rainer is a checker board of clear cuts. |

|
| This is
another pair of tree cover images. I've overlaid them (and with a
little photo trickiness) so that the right hand panel shows
progressive tree cover loss. Those areas that are black were lost by
1972 and are still gone, those areas that are red were lost in the 24
years between 1972 and 1996. White areas are where there still is tree
cover. Yes the growth is shocking... what does it look like now? |

| The forest
cover data likely comes from http://www.americanforests.org/. The
overlay is done by me from this data. I don’t know the source
of
the image of Seattle or the original source of the top maps. |
