Roaring Fork Valley Phenology | October 28, 2013

Since spring this blog has paid special attention to the shrubs in the Aspen area.  We witnessed an amazing flowering season, followed by more berries than anyone can remember. Now we're focusing on our feathered and furry friends that feast on the shrubs' fruit, berries! Bear conflicts have almost been a non-issue in town this summer and fall because of the bumper crop of berries. They should be going into their dens full and fat in the next couple of weeks.

We have been caught in a dilemma the past couple of weeks at Hallam Lake. Five separate snow events have covered the fallen leaves from our numerous cottonwoods. Usually a little snow on the leaves is not a problem for raking. If we wait a few days for the high pressure and sunny skies to show up, the snow disappears leaving light dry leaves that can be easily raked up off of the trails, driveways, and decks. But with the pattern we have seen lately the leaves on the ground have stayed wet and heavy, which are not efficient to move.

Wooly bear caterpillars, the larval stage of the Isabella tiger moth Pyrrharctia Isabella, have been spotted around the Aspen area over the past week or so.

Can the width of the wooly bear’s central rusty stripe predict the length and severity of the coming winter? Folklore suggests if the stripe is thick, a mild winter will follow, and if it is thin winter will be harsh. Have there been any studies to explore this? How did this idea gain popularity?
