Stuck on a Airplane

VAN 046

When I returned from my recent trip to southern California, I had the pleasure of being held on the plane circling for an hour before being sent back to Sacramento. As beautiful as it was in 90% of the county, apparently there was heavy fog at the Aracta airport – and well, you all know the drill around here. At least I got some awesome views of our county. This is over the central-east portion of Humboldt. If you note the savannah-grasslands above the wing, you can see Indian Creek, which is in between the two open ridges. From this vantage you can really see how isolated the oak and savannah types are becoming, as they continue to be rapidly encroached by Douglas-fir.

When I took this picture, the plane was right over McClellan Mountain. The Van Duzen River cuts through the melange geology here. You can still see the grey scars remnant from the 1964 flood. The strange formation in the center of the picture is the Eaton Roughs. I have written about the roughs previously here: http://nooksand.wordpress.com/2012/11/30/the-desolation-2/

    1. Well considering how much we have seen in the past 80 years, I think it wont be that long. 100 years or less! Now some of those truly open soils may not support Douglas-fir now and would take centuries to develop soils that would- but it appears that most of at least the woodland soil types can be encroached.

      The trend I have been noting lately is that the black oak appear to grow on more productive sites, and that is where the encroachment has been the worst. The white oak areas are poor sites, and thus the conifer encroachment rates are slower, though it is happening. Id bet most of the un-encroached woodlands that exist are mostly white oak.
