Dry forests of the Tuichi river 

The second study site of the expedition was conducted between June 22nd and July 5th, 2015, in the dry forests of the Tuichi River. The camp was established on the banks of the Machariapo river, at 740 m a.s.l., between the communities of Sipia and Suyo Suyo.

These forests contain a greater diversity of species as compared to other dry Andean forests in the Tropical Andes, as well as a great variety of endemic species. The dry forest is isolated because it is surrounded by montane forests and humid piedmont forests. Its flora is similar to that of the Chiquitano forests, the piedmont forests of the Tucumán-Bolivian region and the inter-Andean dry forests of Bolivia and Argentina, with characteristic species such as bromeliads, cacti and palms.

In total, 162 species of plants, 130 species and subspecies of diurnal butterflies and 265 species of vertebrates were recorded, of which 68 are new species for Madidi, 26 for Bolivia and 7 possible new records for science.

Mid-montane forest

The ninth study site of the expedition was conducted between September 25th and October 9th, 2016, in the Yungas mid-montane forest, with an altitudinal gradient between 1,700 to 2,700 m a.s.l. The camp was located in the Cargadero area, a three-day hike from the town of Puina, along the bridle path that connects to the town of Mojos.

The mountainous topography has very steep slopes. The montane forests dominate, with a small portion of treeline forest. The lower altitudinal limits from 1,300 to 1,700 m a.s.l. are seasonally humid Yungas forest, and the mid-montane pluvial Yungas forest develops between 1,700 and 2,600 m a.s.l.

In total, 368 plant species, 150 species and subspecies of diurnal butterflies and 197 vertebrate species were recorded, of which 76 are new species for Madidi, 6 for Bolivia and 33 for science.

Montane rainforest

The eighth study site of the expedition was conducted between June 16th and July 7th, 2016, in the pluvial montane forest of Mamacona, in the Yungas between 1,500 and 1,800 m a.s.l. The camp was located on the banks of the Huarajo river, one of the headwaters of the Hondo river.

The landscape is a set of hills, with associated ravines and small rivers. It contains medium-sized trees and very few tall trees, and in the upper hills and on the plateaus, the trees are small. It is characterized by high densities of a palm tree known as tola and the copal tree. In certain sectors there are immense patches of tacuara or bamboo.

In total, 378 plant species, 171 species and subspecies of diurnal butterflies and 239 vertebrate species were recorded, of which 76 are new species for Madidi, one for Bolivia and two for science.
