Can Valldaura Monitoring program

  1. 1. QV monitoring program The landscape process 1905 2012 1905 2011 100 years ago. Crops with ploughless agriculture. Land-use abandonment drives to a biodiversity loss. The forest was exploited to make charcoal. More Flora and fauna linked to open habitats gone nearly water on streams with fishes. Very high biodiversity extint. Pinus halepensis, once the main structural due to the agricultural/forest interface. Key species component of the forest, is now in decadence. Great were abundant. risk of forest fire forces constant efforts on forest fuel extraction in order to reduce fire risk. Now Greenfab Lab is changing the landscape structure in order to Shift the water cycle Get open spaces with Plant different crops Make energy balance to the blue grass cover (crops (different intensities of from the forest water system (runoff and grazing) management) biomass and well water) Optimize rainwater harvesting and water management without affectin the drainage ecosystem Optimitze traditional and And so a monitoring program is That will lead to experimental crop estrategies needed in order to get an adaptive management estrategy Optimize the positive impact on landscape and biodiversity Physical and Biological processes to be controlled Soil erosion controlBlue water-green Forest Open habitat flora and and fertility water balance structure fauna recovery enhacement The cleared areas and also the untouched ones can have changes in their 3D structure. So we need fixed datums and points of view in order to have visual and temporal references. IR photography and fish/eye photography ban be of great help. Placing pluviometers on different places can help to measure the rate of rain interception of the forest canopy. Relative humidity and temperature are basic data. The difference of leaf and air temperature is a good indicator of water stress during summertime. Trunk diameter changes on broadleaved trees is a good indicator of the water availability and water stress. Notch weirs are used to measure water discharge on streams and channels. An adaptation of the system can be used for the existing subterranean water mines. Runoff plots are needed to know which level of rain intensity overcomes infiltration and promotes superficial runoff. This is reqalted to slope and class of cover. Forest clearances should make easier to get water runoff for lower precipitation. A shift to blue water. Erosion pins are simple and precise devices for measuring erosion. We only need to place the pin at a GPS positioned place and measure the distance to soil surface with a precision calliper. There is also an urgent need to provide efficient homes for desired fauna. As rabbits went extinct time ago, we need to make safe places for their colonies with palets. We should also place safe nestboxes for different species of owls. Specially for barn owl (Tyto alba), little owl (Athene noctua), and scops owl (Otus scops). The existing and frequent tawny owl (Strix aluco) is also welcomed.
