Acid rain in Big Sur – October 2011

The rainy season has started early again this year in Big Sur, with the first rains falling on October 3. October rainfall at my rain gauge (see station photo below) totaled 3.53”. Below are the pH readings. Three of the four readings are notable higher (less acidic) than usual here in Big Sur, though all the readings are more acidic than what is considered normal for unpolluted rainfall pH (~ 5.6). This is not meant to imply, however, that the acidity measured here in Big Sur is due to anthropogenic pollution. There is a distinct possibility that a portion of the acidity is coming from natural, oceanic sources. Still, no one knows for sure where the acidity in the Big Sur rain is coming from.

Monterey oaks improving despite oak worm/moth infestation

4 11 2011

Last week I visited some oaks in Monterey that were first treated with fire mimicry last year at this time. This year there has been a heavy oak worm/moth infestation in the area with many oaks being nearly defoliated. However, most of the treated oaks shown here have not only survived the infestation, they are actually showing signs of improved health since last year. See the photo comparisons below:
