FAQ'S

Roots are very shallow in rainforests. The rainforest soil is poor in nutrients available at surface level. The tall trees have developed buttress roots to create the support they need. These roots may reach 15 ft of height above the ground and they increase the area over which nutrients are absorbed.
Most of the root biomass is in the first 0.3 m of soil.

Key species:
According to our research, monitoring and carrying out projects with specific species may not be the ideal way to develop our project. A tropical rainforest contains an average of between 20 and 86 species of trees per acre (this may sound as a very wide range, but compared with about 4 species in temperate zone forest this range is enough to make our point). This means there is a great variety of species, but it also means that there are fewer individuals. In fact, there may be zones where you won't find individuals from certain specie. Therefore, there are no dominant species in tropical rainforest. Plants of the same specie do not grow together. Selecting species will not cover the huge biodiversity of the Amazon rainforest. But we recommend using epiphytes as indicators of the state of other plants if necessary.
