| Taken in June
2002, this image showing land cover for central Puget Sound. Dense
Urban (75% Impervious Surface) are in Black; light-medium urban area
(10-75% impervious surface) are in Red; agriculture/grass in brown;
mixed and deciduous forest in light green; coniferous forest are dark
green; wetlands light green; shoreline
gray; water blue. |

| The image on the
left is a closer view of the area around our forest. In this image I've
changed the agriculture/grass areas to white instead of brown so they
show up better. On the right is a satellite image of the area with a
yellow arrow and dots marking where our forest is. As our forest is a
mix of coniferous and deciduous forest, it shows mostly as light green.
It is easy to compare the two images and see the spread of houses
tracks with the increase of impervious surfaces. The increase of red
and black areas mean the decrease of areas for wildlife. We do see a
green corridor still running down the center of the map, so there is
hope. |
