  Argentina is one of the most biodiverse countries in the world hosting one of the greatest ecosystem varieties in the world: 15 continental zones, 2 marine zones, and the Antarctic region are all represented in its territory. This huge ecosystem variety has led to a biological diversity that is among the world's largest: 9,372 cataloged vascular plant species (ranked 24th); 1,038 cataloged bird species (ranked 14th); 375 cataloged mammal species (ranked 12th); 338 cataloged reptilian species (ranked 16th); and 162 cataloged amphibian species (ranked 19th).
  
  The original pampa had virtually no trees; some imported species such as the American sycamore or eucalyptus are present along roads or in towns and country estates (estancias). The only tree-like plant native to the pampa is the evergreen Ombú. The surface soils of the pampa are a deep black color, primarily mollisols, known commonly as humus. This makes the region one of the most agriculturally productive on Earth; however, this is also responsible for decimating much of the original ecosystem, to make way for commercial agriculture. The western pampas receive less rainfall, this dry pampa is a plain of short grasses or steppe.
  
  The National Parks of Argentina make up a network of 35 national parks in Argentina. The parks cover a very varied set of terrains and biotopes, from Baritú National Park on the northern border with Bolivia to Tierra del Fuego National Park in the far south of the continent. The Administración de Parques Nacionales (National Parks Administration) is the agency that preserves and manages these national parks along with Natural monuments and National Reserves within the country. Argentina had a 2018 Forest Landscape Integrity Index mean score of 7.21/10, ranking it 47th globally out of 172 countries.
