a S T A M M E R project 2011 May 22 to June 3 It may be the influence of a fellow
photographer or of the recent meteorological conditions but fact is
that sky and clouds fascinate me more than ever. The geographical location of our
zone may be quite privileged as well, just at the frontier between
the dry, clean skies of the Ebro valley and the frequently stormy
weather conditions of the Pyrenees. And then the views from our
place over the Pyrenean skies are unbeatable.

The stormy skies brought a lot of rain recently which was especially beneficial for the vegetable garden, the ponds and the green roofs. The next pictures give an impression of the four green roofs, each of them featuring a completely different substrate. For the moment the roof of the garden house and of the toilet building are the only ones which don't receive any additional watering. For a more detailed account of the green roof development see the corresponding section in the index.

This
picture was taken half May and shows abundant but quite ephemeral
growth of Medicago minima on the garden house roof
(see right picture). 13 May 11:37 |
The same corner 2 weeks later
than the left picture but without Medicago minima for which
the soil layer of 6cm is probably too shallow; no problem for the
yellow Sedum acre. 1 Jun 12:36 |
|
Little by
little the red tinged Sedum anglicum is occupying the empty
spaces with the expanded clay pellets. 1 Jun 11:38 |
Sempervivum tectorum is
going steady but slowly. 1 Jun 11:45 |
|
The
drain-pipe couldn't cope with stormy showers of 20lt in 15 minutes
but the overflowing water didn't cause mayor problems thanks to the
stones and the roof rim finish. 1 Jun 12:39 |
|
The green roof of the washing
machine shed is doing fine with only an occasional extra watering to
help the Sedum cuttings establish. 2 Jun 11:42 |
The
improvised green roof of the compost toilet building is furnished
with knobbed roll (HDPE) left-overs. Not completely watertight but
the knobs help to prevent the sliding of the substrate. 3 Jun 10:26 |
The roof of the fire wood shed
is not very green and needs regular watering. On a waterproof EPDM
sheet I put straw, tiles and then some soil in which I planted
Sedum cuttings. 3 Jun 10:22 |

The upper pond had dried out somewhat, causing quite some damage to
the macra alga vegetation of the Chara species which I don't
regret too much: it suffocated other aquatic plant life. At some
point I decided to add water from the mains and subsequent stormy
showers filled this pond up to the brim (helped by the tube from the
garden house roof to the pond). Although the mains water was added
very slowly, the resulting temperature shock and possibly the
nutrients and chlorine in this water
were disastrous for aquatic animal life as very few insects could be
seen afterwards. In the future I will add water from the mains in
less quantities and even more slower.

Ladder snake (about 100cm long) in the almost dry upper pond. |
Close-up of the beautiful snake. |
|
The lower
pond didn't receive water from the mains and counts uncountable
water fleas, water snails and backswimmers. 2 Jun 11:21 |
After the showers and the
fill-up the water in the upper pond is crystal clear but with very
little water wildlife. |
|
The cat family is alive and kicking. They move tactically every 3 of 4 days but their main base seems to be the compost toilet building. The kittens remain very timid and only Blanca is able to catch them with the exception of the black one which is nervous and explorative, not very sociable and going his own way (probably a male so).

First climbing lesson. |
Inspecting the compost heap. As can be seen, the heap (1 m3) is only half full, after receiving on average one human 'call of nature' per day for two years so far. 3 Jun 9:56 |

The vegetation of the zone is looking beautiful with an infinite
number of details and shades which are impossible to show
satisfactorily on a computer screen. This is a pity because so many
people are blind for this kind of details (having ultra-high
definition eyes) and only say mechanically How beautiful!
when they see the overkill of colours and forms of a typical
flower garden with lawn. But (with some effort)
I have to stop preaching, force myself to make a concession and show
some
close-ups of two conspicuous plants: the orchid Anacamptis
pyramidalis and the impressive thistle Onopordum acanthium.
Of the first I counted more than 50 flower heads, considerably
more than the 11 specimen I counted in
2007. |
