2007 April 14 & 15, Saturday & Sunday


Even more rain had fallen in the previous weeks so it was no surprise to find the terrain and the surrounding fields in an astonishing green colour. There was still a lot of humidity in the air and especially Sunday was a strange day with thick layers of mist and clouds but also some longer spells of sunshine.

The massively germinated annual Alyssym alyssoides is reaching the end of its flowering cycle.

No surprise to find some nice surprises in this period of the year. Saturday still with buttons but on Sunday the first flowers started to emerge from this Lady orchid (Orchis purpurea), another characteristic species of dry chalk grasslands (Festuco-Brometea). I had the impression that all the orchids on the terrain belonged to the same species because of their similarity of their rosettes (compare 10 March 2007). The Lady orchid distinguishes itself nicely from other local orchids because of its relatively robust size and height (up to 80 cm; according to the 'Herbario de Jaca').

The Portuguese oaks (Quercus faginea) were also starting to bloom although in a much less conspicuous way.
The Common fig (Ficus carica) has something architectural about its shape and unfolding of the leaves. The old Fig I had pruned  was budding promisingly while the buttons of the cuttings of the same tree I had planted in February seem to have dried up. Perhaps some lateral buttons will take over.

This weekend as well as last week I worked quite a lot with stones. I chose adequate stones from the stone wall which I could handle and transport with the wheelbarrow. For their placement I chose the area on the highest terrace in the western part where the soil is relatively bare with little vegetation. There the stones will not be at risk of being overgrown by plants and at the same time they will offer some shade and temperature buffering for the vegetation.
Some lessons I learned on the run:

  • Even these relatively small stones are extremely heavy

  • Even the ugliest stones can have an interesting touch if you choose the right position and angle and won't make a point of burying in some cases more than 70% of the stone into the ground.

  • One corresponding hole in the ground produces one wheelbarrow load of earth.

 

 

 

 

 

 

 

 

 

 

This experience leads to some question marks as what to do with the big ones of the stone wall. We will need a bulldozer to transport and manipulate the stones and I am afraid that it will have an enormous impact on the terrain: soil compaction, big holes, piles of superfluous soil. Perhaps it won't be possible to manipulate and change the position of the stones as we want and we get stuck with some really ugly, out of place monoliths.
So we are seriously considering the option to leave the stone wall where it is, adding some soil to help vegetation growing there and planting some rock plants.
