Paramo grasslands in Northwest Peru. Photo: Alexander More. Paramo Grasslands Unlike the puna grasslands, the paramo grasslands are rather humid grasslands mixed with shrubby vegetation. The Paramo Grasslands occur above treeline and above the montane evergreen forest and elfin forests. Scattered small lakes and boggy depressions are common features in Paramo habitats. Paramo grasslands occur […]
Typical riverine sand beach showing some of the first colonizing shrubs. Photo: Diego Calderon. Riverine Sand Beaches Riverine sand beaches occur largely in whitewater Amazonian rivers, which are subject to changes in water levels of up to 7 meter between the wet and dry seasons. During the dry season, extensive sandbars are exposed along the
Puna grasslands in the Andes of Cusco-Peru. Photo: Nestor Ccacya. Puna Grasslands The puna grasslands occupy the higher mountain slopes and plains of the Andes from northern Peru south to northern Argentina and Chile. Puna grasslands are found generally above 3,500 meters. They are largely dry grasslands but vary in floristic composition from pure grass
Northern temperate grasslands in Mexico. Photo: Ken Lund. Northern Temperate Grasslands The northern temperate grasslands occupy large areas of northern and central Mexico at elevations of about 1,100 to 2,300 meters. Floristic composition varies with elevation and location. Unfortunately, the northern temperate grasslands have been heavily impacted by overgrazing and excessive fire. Large areas of
Southern temperate grasslands in La Pampa, Argentina. Southern Temperate Grasslands Southern temperate grasslands include several types of grasslands. This habitat type covered much of extreme southeastern Brazil in southern Rio Grande dos Sul, Uruguay, and Northern Argentina, extending locally to Tierra del Fuego. Conversion of the Pampas to pastureland was nearly complete by the early
Panoramic view of a habitat classified as low, seasonally wet grasslands in the Venezuelan Llanos. Photo: Araguato. Low, Seasonally Wet Grasslands Low, seasonally wet grasslands include a variety of grassland types, which occur in well-drained slightly higher grounds. These type of grasslands are wet but become hard and dry during the dry season. Low seasonally
Campo grasslands. Photo: Alessandra-Fidelis Campo Grasslands Campo grasslands are upland grasslands with little or no woody vegetation. This habitat type occurs locally in the Brazilian and Guianan shields. The complexity and grass diversity of these grasslands vary from region to region. Grassland savannas occur in northern Venezuela and northeastern Colombia (Llanos) Southeastern Venezuela (Gran Sabana), the
Semi-humind montane scrub in an inter-Andean valley in central Peru. Semi-Humid and Humid Montane Scrub The Semi-humid and humid montane scrub are zones of moist dense shrub and scrub. These habitat types are generally found at elevations of 2900-3000 meters, particularly in moist inter-montane valleys and extend up to the puna grasslands. Semi-humid montane scrub with patches
Pine-Oak forest where oaks are a dominant species of tree. Photo: Jon Anderson/Flickr Pine-Oak Forest The Pine-Oak forest is found in the mountains of Northern Mexico through Nicaragua mainly at elevations ranging between 900-2800 meters. Throughout its range, this forest ecosystem is composed of a mix of oak and pine with oak species replacing each
Tropical deciduous forest during the dry season in Piura-Peru. Definition: Tropical deciduous forests occur in regions with heavy rainfall for part of the year followed by a marked dry season. These forest formations are dense and lush during the wet summers, but become a dry landscape during the dry winters when most trees shed their
