Paramo or puna?
Paramo is a South American term referring to a high-altitude moorland habitat above the tree line (and below the snow line) in tropical areas of South and Central America. It generally occurs between roughly 3,000–5,000m of altitude.
It is characterised by tussock grasses, cushion plants, evergreen shrubs and the distinctive Espeletia genus, known as frailejones, which form big leafy rosettes atop thick woody stems. Also common are puya, a member of the bromeliad family, which, like the frailejones, form leafy rosettes, but close to the ground.
Paramo receives a lot of rainfall, typically more than 2,000mm a year. In South America, it is mainly found in Venezuela, Colombia, Ecuador and northern Peru. Further south (in southern Peru and Bolivia), the habitat above the tree line is similar, but tends to be drier and is known as puna.
Some woodland can occur on paramo, with shrubs and trees forming what are called dwarf or elfin forests, which often grow to no more than a few metres high.
