Funny loggers...

Not sure what they do this, if it for testing wind issues / downfall or just wanted to leave a mark for Google earth but you see this all over up in an area I ride. Can see them from some of the view points. Dice anyone?

GP Yahtzee?
That's 10pts for the CHANCE box.


Strange indeed.

Or a domino....Very weird, got any illegal "aliens" up in the PNW???

Oh my gosh, crop circles on a mamoth scale. The extraterristials in you're area must be giants.

Bit bigger than the English crop circles. I wonder what its all about, then again I wonder why I am bothering to wonder at all.

Maybe they are not destroying someone's crop and livelihood in this case ... Looks like weyerhauser work ... they got plenty to waste ...

Here is your answer Kelly... my sister works in high levels for the BC Forest Service. There are several tests being done in BC and in the forests of Washinngton State/PNW..
Basically a large scale Moss test.

This is from her....

"it would appear that they are “circular forest aggregates” used for various studies. See this article for some info:

Short-term effects of timber harvest and forest edges on ground-layer mosses and liverworts



Cara R. Nelson and Charles B. Halpern


Abstract: Limited information exists on the effects of forest management practices on bryophytes, despite their importance to forest ecosystems. We examined short-term responses of ground-layer bryophytes to logging disturbance and creation of edges in mature Pseudotsuga forests of western Washington (USA). The abundance and richness of species were measured in four 1-ha forest aggregates (patches of intact forest) and in surrounding logged areas before and after structural retention harvests. One year after treatment, species richness, total cover, and frequency of most moss and liverwort taxa declined within harvest areas. Within forest aggregates, mosses did not show significant edge effects; however, richness and abundance of liverworts declined with proximity to the aggregate edge. Our results suggest that, over short time frames, 1-ha-sized aggregates are sufficient to maintain most common mosses through structural retention harvests but are not large enough to prevent declines or losses of liverworts. Thus, current standards for structural retention, which allow for aggregates as small as 0.2 ha, may be inadequate to retain the diversity and abundance of species found in mature, undisturbed forests.
Key words: bryophyte, edge effects, forest borders, forest management, logging effects, structural retention harvest.

Good stuff, figured it was for some sort of testing.

I'm sure that Tim is correct but it was much more fun to entertain the idea of really big aliens.

Sorry.... guess I was the "FunSucker" as my nine year old daughter would say.....to anyone that ruins her day....
