Im in the south of Portugal - Algarve, I guess zone 9?
On my land there is what i recently found to be old spring that has dried up.
I noticed in winter (when it rains) that it starts trickling again and there are some moisture loving plants that seasonally grow here.
Further down it fills up the well which stays with water until the end of June.
At the moment there are some very old stone oaks still planted but the rest of the little valley is completely dry and exposed. And Im guessing and hoping this is why the spring has disappeared.
Last winter before I realised it used to be a spring I started planting the trees I had in pots around (the spring source)
A little further down I noticed that even as little as 10 cm beneath the top soil was super wet.
My question is which trees do I plant to replant the spring ?
So far I have put in the vicinity:
Monchique oak (Quercus Canarienses)
Wild strawberry (Medronho)
Are any of these a bad tree to plant i.e. will it deplete the water instead of plant it?
Also about 40 meters higher is the old ruin that Ill be reconstructing from its original Taipa (mud)
Ill be pulling down the outhouses that were built from old bricks etc and as the slope is quite steep in front of the house and as I want to have minimum waste, Im planning on using the rubble to extend the area in front of the house using the rubble and dirt instead of removing it with a skip.
Do we think this will affect the (currently dry) spring further down (around 40metres) in a negative way or by planting more trees would it raise the water table somehow through the covered rubble?
