Grasslands are their only home

Within the grasslands, a significant number of Key Biodiversity Areas (KBAs) y Important Bird Areas (IBAs) have been recognized that harbor a wealth of biodiversity. For example, in the pampas and plains of the Southern Cone, thousands of species of vascular plants (+550 grasses) have been detected.

The diversity of vertebrates is also high. For example, in these grasslands there are:

+ 540 species of birds + of 138 mammals + of 225 reptiles


LUnfortunately, according to the International Union for Conservation of Nature (IUCN), 130 species are under some degree of threat. Of the 109 bird species recorded, more than one-fifth are globally threatened to some degree.


Even more worrying is that less than 0.2 to 0.5% of these territories are protected by State Protected Areas. For this reason, it is vital to guarantee the long-term protection and recovery of grasslands through conservation and sustainable production plans. In this way, not only biodiversity is protected, but also its cultural and livestock legacy.
