2006 October 21 & 22, Saturday & Sunday


Nine o'clock Saturday morning. Much fog and humidity but it would be sunny soon with temperatures up to 20ºC. The cobwebs give a good impression of the spider population on the terrain.
We also detected other mushrooms, among them  Astraeus hygrometricus which has the curiosity, as its name suggests, of opening like a star in 5 minutes  when in contact with water.

Also becoming quite active were the earthworms. The ones we have seen were all of considerable size and thickness (photographs will follow) and in some parts of the terrain they had almost literally ploughed the soil, leaving the typical hillocks of granular soil. It's clear that this activity is very good for the soil structure but in some cases I dared to suspect that it presented an obstacle for the forming of a vegetation layer. A plant that was able to colonize these hillocks was a tiny species of moss with an almost fluorescent green colour.

 

 

 

 

 

 

 

 

______________

 

 

The hillocks of the earthworms colonized by an unknown moss species, together with an Echium vulgare recently germinated.

Poa bulbosa (here with white stems) also seemed to prefer the hillocks. Here together with Thymus vulgaris and a Medicago species.

Another grass species in this area was Avenula bromoides with a special blue-green colour

Here an image of the zone in question from 3 weeks ago. The area with less vegetation and a lot of hillocks is on the left. Probably the trees which swallow a lot of humidity, together with the higher altitude, are mainly responsible for the bare and dry character.

 

 

______________

Another question is if we have to intervene to protect the soil or if we must let it go. Candidates for covering the soil are abundantly present in other parts of the terrain. It could be an interesting experiment to plant some specimen like:

Hieracium pillosella. Its best flowering season is spring (as happens with the other species here presented)

Potentilla reptans forms authentic plaques in some places .

Helianthemum violaceum. Behind it a recently arrived sapling of Quercus faginea

Centaurea scabiosa  is not exactly a plant that forms carpets but it may protect the soil with its rosettes.
22 Oct 16:19

 

A plant that colonized many barren and dry areas was an annual species of Medicago or Trifolium. Because of the absence of flowers and fruit I haven't been able to determine it yet.

Daucus carota has to be esteemed for its enormous attraction for insects...

 

Another plant that was becoming more and more prominent all over the terrain was Daucus carota, the wild carrot.

 

 

 

 

 

 

 

 

 

 

...and its almost architectonic build.

______________

At first we thought that this animal was the culprit of some very strange bubbling noises that could be heard coming from different directions at the same time, especially when stepping firmly on the ground. Later on we considered the possibility of the noise coming from the subterranean tube system made by the giant earthworms. As of January 2007 the noise couldn't be heard anymore. Let's see if they start to appear again in spring..
