Tanzania is one of the most biodiverse countries in the world, and is home to some of the most iconic places on earth. The country boasts 19 national parks, including the world-renowned Serengeti National Park, the Kilimanjaro National Park, and the Ngorongoro Conservation Area. It also hosts 25 game reserves, 3 marine parks, 15 marine reserves, and multiple forest reserves. Tourism is a key engine of growth, representing 13% of the national Gross Domestic Product. However, habitat degradation, poaching, overexploitation of biological resources, and climate change are threatening this rich array of resources. The Government of Tanzania is devoting significant efforts to the fight against poaching and illegal wildlife trade, and positive results are already showing.
