Title:  The nature trial of the miner  -  a project for biodiversity preservation of Brusada-Ponticelli area. 

Context: a  project aiming at individuating  and safeguarding the rare botanic species around the mine of Brusada Ponticelli through:  1) An educational and environmental laboratory aiming at increasing   people awareness towards biodiversity protection. 2) An experimental yard to test the most suitable techniques to restore the identified area. 3) A project never carried out in Valmalenco to preserve autochthonous rare species in the identified area  in order to increase the conservation of their genetic heritage. 4)  A nature  trial carried out with the realization of 8 panels describing the most important aspects of environmental and local morphology.
Solution: during summer of 2009 an  accurate survey  has individuated the following 4 interesting rare species:   Armeria Alpina, Carex bicolor, Saxifraga Rotundifolia and Sanguisorba dodecandra.  These species have been cultivated ex – situ in a specific laboratory and after their germination have been gathered and reintroduced in the nursery set for biodiversity preservation.  In addition -  thanks to the cooperation of two   naturalists  - some panels have been designed  in order to create a specific trial along which people can be led to discover  conifers, broad-leaved trees, lichens, woodland animals, woodland flowers and learn more about evolution of species. In the same period the involved naturalists have also  tested - in the identified area  -  two different restoration  techniques in order to choose the most suitable one.
Results : three of the above mentioned species (Armeria Alpina, Saxifraga Roundifolia and Sanguisorba Dodecandra),  gathered on spot and then cultivated in the laboratory, have germinated and  have been reintroduced in the nursery set to guarantee their genetic heritage. Whereas the fourth species (Carex Bicolor),  that has found difficulty in germinating,  was sent  at the laboratory for a second attempt of reproduction. Furthermore the best restore technique has been defined after having compared two autochthonous  mix  of seeds,   one of them has in fact reported a better growth and has been chosen for eventual future intervention. Recently the seedlings placed in the nursery were transferred to the natural environment within this area.
Guiding tours  with experts naturalists  can be booked at  the City Hall each month. Thanks to this initiative,   visitors can better  understand that  the diversity of living things results from the evolutionary  process, which starting out from the original forms has led to a continuous differentiation. In addition, didactic  activities can be planned  thanks to a permanent laboratory  kit reserved for school workshops, through which kids can learn through simples activities of observation the true meaning of biodiversity.
