The natural barriers separating Chiloé from Chile create special conditions that enable the existence of unique and valuable species and marine and land ecosystems on the Island. 
In this context, public access to Parque Tantauco is an important opportunity given that its territory is located on one of the world’s 25  Biodiversity Hotspots (www.biodiversityhotspots.org/)Moreover, its surface is part of “Sitio Chaiguata”, defined by Chile’s CONAMA (National Environmental Commission) as a priority spot for the conservation of wildlife. 
The Park’s flora includes species such as the Guaitecas cypress (Pilgerodendron uviferum) and the coastal Olivillo (Aextoxicum punctatum); its fauna includes the huillín otter (Lontra provocax), the chilote fox (Pseudalopex fulvipes) and the blue whale (Balaenoptera musculus).
