CANTILLO HIGUERA, Edgard Ernesto; LOZADA SILVA, Alberto  e  PINZON GONZALEZ, Julián. Successional study for the restoration at Cárpatos forest reserve in Guasca, CundinamarcaCaracterização sucessional para a restauração da reserva florestal de Cárpatos, Guasca, Cundinamarca. Colomb. for. [online]. 2009, vol.12, n.1, pp.103-118. ISSN 0120-0739.

Based on floristic and structural characterization, four stages of secondary succession were analyzed within a matrix of vegetation that had been disrupted (185 ha) at Cárpatos Forest Reserve. This reserve is located in the foothills of Colombian's Eastern Mountain Range (Cordillera Oriental), among 2600 and 3000 meters above sea level, and it is aimed at making a contribution to prepare a restoration protocol. In flat, wet areas, vegetation represented by grassland whit Rubus floribundum y Pteridium aquilinum, grows up to 0.7 m height on average. It is characterized by Pteridium aquilinum, which holds an average of 1638 individuals per 0.1 ha and a total of four species with the same number of genera and families bushes of Solanum inopinum and Chusquea scandens, less than 3 m height, were dominated by Chusquea scandens, with an estimated average of 638 individuals per 0.1 ha and a total of four species and the same number of genera and families. In areas of steeper slopes and lower humidity more structured vegetation grows. This forests in recovery dominated by Miconia theaezans y Myrsine coriacea, which contains two types of vegetation: Hedyosmum crenatum y Myrsine coriacea, which are dominated by a shrub layer no taller than 5 m, with Myrsine coriacea as its most important species, and an estimated average of 1742 individuals per 0.1 ha and a total of 18 species, 16 genera and 13 families, and Weinmannia pinnata y Miconia theaezans, represented by Myrsine coriacea, Miconia theaezans and Weinmannia pinnata as important species, which held an estimated average of 1833 individuals per 0.1 ha and a total of 14 species, 12 genera and 11 families. Myrsine coriacea, Miconia theaezans, Weinmannia pinnata and Hedyosmun crenatum are regarded as the most suitable to start reproductive, adaptive and developing silvicultural protocols. Management analysis suggests that there is a correlation between higher clay content and the secondary-succession initial-state communities, while in previous stages the values are higher in terms of sand content, cation exchange capacity, organic matter and slope.
