CANTILLO HIGUERA, Edgard Ernesto; CASTIBLANCO GUTIERREZ, Viviana; PINILLA MONDRAGON, David Fernando  and  ALVARADO, Claudia Liliana. Characterizing and valuing of regeneration potential of the seed germination bank at the Carpatos forest reserve (Guasca, Cundinamarca). Colomb. for. [online]. 2008, vol.11, n.1, pp.45-70. ISSN 0120-0739.

In the Cárpatos Forest Reserve the bank seed germinate (BSG) was marked and valued and the dispersion mechanisms and strategies of there serve defined. They subsequently determined the spatial, dinamogeneticand temporary structures of the seral states and their populations. For the vegetation on foot 61 species were recorded, represented by 53 genera and 36 families, alongside the BSG were 55 species, represented by 50 genera and 27 families. The minimum volume was 1.500 cm³, for a total of 13.150 germinating seeds; the total density for BSG was 1.553 seeds per m². The species emerged in the BSG were mostly herbaceous and flush - approximately 70% of all individuals and species -; Phytolacca bogotensis, Digitalis purpurea and Ageratina sp. were the dominant species in the three trials Bank, other important species were< I>Carex sp., Poa annua, Rubus floribundum, Bulbostylis sp.and Borreria sp. The species of woody habit usually varied in each trial according to the phenophase of each species, the most representative species were Cestrum Mutisia, Clusia ducu, Myrsine coriacea, Axinaea macrophylla and Miconia denticulata. As for phenology and dispersal, it was found that vegetation stands submitted to the zoocoria as the dominant scattering strategy in all fields; the maximum flowering occurred during the dry season, from December to March, though the greatest fruiting records correspond to the longest rainy season, from June to August.
