For years the ecofort GmbH Nidau (CH) familiar on the synthetic hair hygrometer from FISCHER. Now this hygrometer is used for the conservation of West African desert crocodiles:
The ecofort GmbH supports the efforts of Michel Ansermet (research associate of Aquatis, the formerly Vivrarium de Lausanne) to preserve the West African desert crocodiles from extinction. In Europe there are only 3 such crocos, in Lausanne is the only couple. While there were 1946 in Africa more than one million of them, today only 1,500 to 3,000 of these animals are counted.
Nature has done with the help of Michel Ansermet a miracle.
