OLIVA, Manuel et al. Floristic composition of herbaceous forage species in natural prairies of the main livestock watersheds of the Amazon region. Scientia Agropecuaria [online]. 2019, vol.10, n.1, pp.109-117. ISSN 2077-9917.  http://dx.doi.org/10.17268/sci.agropecu.2019.01.12.

There is a great diversity of forage species in the natural grasslands of the Amazon region, and there are few studies regarding the identification of them. In order to deepen the knowledge on the subject, the identification of the floristic composition of these species in the ma in livestock micro-basins and altitudinal floors of the Amazon region was carried out. The livestock microbasins identified were Shocol, Leyva, Ventilla, Alto Imaza, Pomacochas, Condechaca and Leymebamba. On the basis of livestock micro-basins and natural grasslands, two variables referring to production systems (silvopastoral systems, SSP, and open field pastoral systems, SPCA) and four altitudinal ranges were defined: <1900 m.a.s.l., 1900-2400 m.a.s.l., 2400-2900 m.a.s.l. and> 2900 m.a.s.l. Transects were used, identifying a total of 34 families and 113 species between forages and non -forages, of which 27 species were classified as forage species that group a total of 05 families. We found percentage differences of abundance and diversity among species with respect to the variables studied.
