- Abstract
Silvopastoral systems have been promoted as part of a strategy to improve livestock productivity and ecosystem services in the Cesar River Valley, Colombia. Between 2014 and 2017, patterns of diversity, structure, and composition of the vegetation (> 2.5 cm DBH) were studied in 35 plots of 1000 m2 located in silvopastoral systems, conventional pastures, and forests in cattle farms of the region. A total of 1852 individuals were registered, distributed in 281 morphospecies, 109 genera, and 44 families. The most abundant families were Fabaceae (35%), Bignoniaceae (7.5%), and Myrtaceae (6.7%). Leucaena leucocephala (Lam.) de Wit, Eucalyptus cf. tereticornis Sm., and Roseodendron chryseum (S.F. Blake) Miranda were the most abundant species. Forest fragments and riparian forests presented the highest values for plant density, canopy cover, leaf index, the total volume of vegetation, and species richness, followed by paddocks with scattered trees and mixed fodder banks. The largest trees were found in the relicts of forests and paddocks with scattered trees (Peltogyne purpurea Pitter., Enterolobium cyclocarpum (Jacq.) Griseb., Anacardium excelsum (Bertero & Balb.) Skeels., Ceiba pentandra (L.) Gaertn., and Albizia saman (Jacq.) Merr.). Silvopastoral arrangements contribute to landscape connectivity and complement the role of forest fragments to conserve 14.2 % of the tree species in the Cesar River Valley. However, restoring this landscape requires conserving and connecting existing forest fragments, scaling up livestock systems with trees and shrubs, and integrating a greater diversity of native species across all land uses.
