Las Torres stream, Noel Kempff Mercado, Bolivia
Bolivia, Plurinational State of, Santa Cruz
Riparian forest, swamp forest, and seasonally inundated savanna in the lower areas, with deciduous forest (cerradão) and rocky outcroppings on the slopes. Two clear water streams flow from the adjacent serranía. Trails with access to the Huanchaca plateau (Serranía Negra). Site near to Río Iténez/Guaporé. Closest place with people occurence: Camp of park guards with few facilities on bolivian bank; Vila Neide on brazilian bank.

- Surrounding area
Swamp forest mostly where water from underground springs filters through soils at the base of the escarpment. The most noteworthy structural characteristic of this site is the high density of stems, approximately 30% greater than the average of most moist upland sites. This type of environment mixes with parts of savanna wetlands.
Terrestrial vegetation near biotope:
- Qualea sp., fam. Vochyseaceae
- Lacistema aggregatum, fam. Lacistemataceae
- Mouriri apiranga, fam. Melastomataceae
- Underwater landscape
Mix of parts with tree roots, logs and grasslands in open areas. Some roundish rocks appear in stream banks and main channel.

- Threats to ecology
Like everywhere on Earth main threat is human. Exploring of natural resources, cutting trees, planting soy and other crops. Fortunatelly the Bolivian government reacts very good in the area of wetlands, and National Park preserves the natural beauty of the area.
Global problem that affects park is a phenomenon called El Nino. This causes draughts, and therefore creates problems in wetland areas. Also high level of CO2 in atmosphere is predicted to reverse the expansion of tropical rainforests. This process can have impact on vulnerability of rainforests to sustain while draugths.

Comment by the expert
Heiko Blessin: Very complete descrition of the biotope parameters. Well done!
Nathan K. Lujan: Little description and/or illustration of the natural underwater aquascape and habitat. Good lists of species and decent references.
