**6. Conclusions**

Seen from above, the Amazon rainforest often appears some floristic and relief uniformity. Conversely, the large extent of continuous natural forests is a mosaic of different ecosystems and overlapping ecotone zones, constituting different environments, and biodiversity in fauna and flora, on irregular topography. The botanical inventories conducted in the Central Amazon have pointed out, in general, a high diversity of Fabaceae in its floristic composition [13], which leads us to propose strategies that can provide instruments for the planned use of these resources. The assessment of the economic potential of biodiversity becomes a priority in areas of high diversity.

In practical terms, the results of these studies could potentially reach the following groups of beneficiaries: the industrial chemical sector of wood products; reforestation companies for timber production or for species suitable for agroforestry systems and for the recovery of degraded areas; small farmers' communities, generating production alternatives; the scientific community, through the dissemination of specialized information; and, the general population, through the dissemination of technical information made accessible to a larger audience.

Recognizing that wood is the most valuable product of Amazonian Fabaceae, there is no doubt that the role of many species in reforestation and recovery of eroded soils may be greater than the current one. Reforestation with legumes inoculated with bacteria from the rhizobium group can be a promising alternative in Amazonian agroecosystems contributing to nitrogen sustainability. The planting of NFTs has been successful in areas disturbed by poor land use, such as those resulting from abandoned pastures and mining activities [25].

In the Brazilian Amazon, even with the maintenance of protection and conservation areas distributed in this biome, such as National Parks, Biological Reserves and Ecological Stations, Natural Protection Areas, etc., the economic potential of wood has been exploited for economic purposes. Despite their economic value for the timber potential, Fabaceae are important in the recovery of degraded areas and in the reforestation of marginal soils to reduce the costs of wood produced as well as obtaining raw material for industrialization [26]. For the products and services that fabaceae species offer is certainly an important resource for exploration, preservation and conservation of biodiversity in the Amazon and, in this third millennium, its valorization to the world.
