2007 February 3 & 4, Saturday & Sunday


This is what we saw upon arriving at our terrain and having a look at the eastern border on Saturday morning. Our neighbour had drastically moved and levelled his terrain for a horse meadow. What also surprises is the deep layer of soil below the chalk rocks. This must be a mayor resource for water and nutrients especially for trees and shrubs.

At the eastern border.

On the highest terrace. Brambles cleared away giving more opportunities to Cornus sanguinea, Ligustrum vulgare, Crateagus monogyna, Buxus sempervirens and Lonicera species.

This weekend I finished the mayor part of all the pruning and clearing. I used part of the cut branches to cover the barren soil on the right but most of the branches and trunks ended up on a wall we had installed on the western border of the terrain. The wall measures 1 by 7 metres with a height now of 1.5 metre. It offers shelter, building materials, humidity and a little bit of warmth to a host of animals. Interesting to know how fast the wall will diminish with time.

Other small elements may offer similar advantages to wildlife. Some thick pine trunks have been scattered over the terrain. Perhaps I will bury some of them  halfway in the soil to accelerate the decomposition process.

 

 

In the next photograph I had just gathered some dispersed stones to pile them up to form a small wall.

The 'biowall' showed an interesting phenomenon on Sunday morning: the area in front of the south side was clearly a little bit warmer than its surroundings. This reminds me of the same phenomenon on the terrain of the 'Ecocathedral' of Le Roy in the Netherlands where it seems that the average annual temperature is some degrees above normal due to the huge amount of stone.

 

 

 

 

Another surprising 'human factor' effect were the green circles around some shrubs near the caravan. A clear result of the fertilizing effect of human urine.

In the same photograph you can see the remainders of the bramble shrubs on the ground (left) which decompose quite quickly.

The extreme temperatures of last week had gone but the temperatures still dropped a bit below zero in the morning. Nevertheless, this specimen of Euphorbia cyparissias seemed to give it a try.

What (orchid?) flower will appear from these rosettes of leaves which appeared here and there on the terrain? A surprise for next spring..

 

And what will remain of these spontaneous ligneous seedlings at the edge of the wood?
