Análisis comparativo de arreglos florísticos utilizados en módulos de restauración

Abstract

The Parque Ecológico Distrital de Montaña Entre Nubes, located in the extreme southeast of the republic's capital, is located at an altitude of 2600 m to 3100 m; an average annual temperature of 12.3 ° C, in addition to rainfall of 800 mm in the northwest of the park and 1,200 mm to the southwest. (Fundación Natura, 2013), has 626 hectares and a perimeter of 30 km. (Secretaria Distrital de Ambiente, 2006). According to Acosta and others in 2008 from the 50 they appeared dynamic, which strongly affected the park degrade the soil and radically changed the physiognomy and floristic composition of native vegetation. Under the contract agreement No. 670-07. Loan BIRF 7162-CO, the "Proyecto implementación de diseños de restauración ecológica en nacimientos, franjas de infiltración y rondas de la quebrada Hoya del Ramo, en el Cerro Juan Rey, Parque Ecológico Distrital de Montaña Entre Nubes" is created. (Fundación Natura, 2013) implementing 2 treatments and 4 floristic arrangements with 56 repetitions, where native species were planted in rectangular and circular modules 1 and several species. In a second monitoring 20 species, 18 genera and 15 families, 824 individuals vs 831 in the previous survey found. The species with the highest IVI was Ageratina tinifolia (43.62); the rectangular module 5 had higher increase in height of its individuals (0.52 m/ year), while the broader module 6 cups (0.87 m2/ year) and had the largest increase in diameter was made in Module 3 (0,62 cm/ year). The modules monospecific favor the appearance of exotic vegetation associated circular modules lie that favors native species determined that the best floristic arrangement is circular design 3 species
