Project summary

Edit project overview to modify the project summary.


The project began in the fall of 2009 and was complete in early August 2012. First were carried out detailed hydrogeological surveying and evaluation and technical and design work for the water supply of the area. By building a system for sustainable maintain adequate hydration was restored water regime on the field. The area was cleared of construction and other waste. Done to overhaul the road leading to the protected area and carve him as cycling tracks, fencing and marking the boundaries of the area, permanent monitoring and security in the period of flowering and harvest. For visitors created recreation areas with gazebos, and information and signposting give detailed information about the area and protected species.
