Edgar Heim was born in Lima, Peru. He studied food engineer in Switzerland and has been working on that profession for more than 25 years, first as production manager, since 2007 as lecturer in operations and supply chain management at the Zurich University of Applied Sciences. Since his boyhood he was fascinated by nature, biodiversity and ecology. Botany and travelling are his beloved passions. Over the years he has collected a large amount of information about the vegetation around the world and accumulated more than 40'000 pictures of plants from different countries. Unfortunately many developing countries do not have any literature about the flora and their biodiversity. For his own sake he compiled his personal field guides and got a lot of compliments and encourragement while travelling. So he decided to publish the personal field guides. One of them is the "Flora and Vegetation of Bali indonesia," another one is the "Flora of Arequipa, Peru," several others are in progress. The author is convinced that knowledge of plants enhances environmental care. Only knowing people will love and care about the species living in their neighborhood. So he hopes to enhance environmental care with his booklets and contribute to global biodiversity conservation.
