A typical phenomena that starts with autumn is the temperature inversion in the nearby valleys, causing abundant fog.

2011 October 23 to 28


October was dry and only at the end of the month there was a depression which brought about 30 lt of rain, which filled up ponds and water deposit (partly because they receive the drain water from the roof of the house).
 Little by little autumn colours are reaching their climax.

'El Camarero' is a kind of stable mate by now, his girlfriend, 'la Frisona´, is a more irregular visitor.

In the last weeks we had some notable visits from wild boar. We almost never get to see or hear them but their excavations all over the zone are substantial, especially in areas with straw cover (for plantings or against erosion). Some earth moving is not bad and might even be beneficial for new plant species to germinate and settle, but to see some areas completely turned upside down is somewhat unsettling, to say the least. I am not thinking (yet) about hunting them down with a riffle, but I have put a mass of bramble cuttings in the areas where they seem to enter the zone. Around the vegetable garden I even planted many bramble cuttings to form a future hedge. The vegetable garden itself has not received many visits and this might be party caused by a number of long bramble cuttings I had laid out over the straw mulch in summer.

The recent rain after the drought was a nice moment to check the hygrometric qualities of Carlina vulgaris, commented last September.  And indeed, the plants are practically dead but the bracts completely folded during the rain.

Carlina vulgaris with completely folded bracts, protecting the flowers from the rain when still alive, but these parts of the plant are dead by now.

  Another thistle, also dead by now, and equally impressive, Onopordum acanthium.
Notice the transparent stem ledges.

The occasional rain shower is probably also quite beneficial for the filter pond, refreshing and washing the pond contents. The water is nevertheless usually quite clear and only one or two days after using the washing machine the water turns white from the (bio-degradable) detergent. Birds almost never cease to bath in the water and they might even appreciate the occasional soapy ingredients.
I detect several dragonfly larvae in the water which seem to survive the changing water conditions and they might have an important role in the fortunate absence of mosquito larvae.
