Time. Maps. Closeup views

A previous post showed the general lay of the land over time in our neighborhood. Here is a closeup of changes we have wrought since we’ve been there. If you click on a photo it will take you to gallery view.

The first conservation treatment brought in a mower to cut down huge old growth scotch broom – scourge of Northwestern natural areas. Smaller trees were sheared on the west side, and near the middle of the 20 acres (2006-2007) to create the savanna and oak woodland. The relatively filled-in appearance after 1994 is likely due to a lot of regrowth of weedy brush (broom and blackberries) over disturbed ground.

Our latest treatment began in 2011. This is where you can see change on the landscape more clearly. We had more trees sheared, and a lot of larger diameter trees were removed – 2011 and 2012 photos show the opening of the oak woodland/savannah in the center and lower left (SW corner) near the pond, where the “boulevard” was opened along an existing pathway with removal of many smaller firs and some oaks).

Although the first treatment brought major changes on the ground, the activity is more obvious from the aerial perspective in the last couple of views – possibly because of the size and number of trees removed with the last cut. Over 100 oaks, and about 100 firs were removed, and they were larger than the ones that were sheared initially.

Another change that is more visible recently is seen in a faint diagonal opening just above the middle in the land of moose and squirrel. This is where fir trees were girdled and are now standing dead trees, plus three large snags intentionally left alive but with most limbs removed. Dead trees and a trail just above them look somewhat like the 1994 view before trees and brush filled in.

So, some real habitat changes now, encouraging the ‘traditional’ residents of the oak savanna and woodland. Got those white-breasted nuthatches (two at least) so maybe they will build a nest this year!

Perhaps I will take you on a video tour soon…
