Floristic and structural study of a forest with zurales in the Arauca municipality, Colombia ; Estudio florístico y estructural de un zural boscoso en el municipio de Arauca, Colombia

We described the structure and floristic composition of a zurales forest with earth-mounds presenting average heights of 1.36 m and average diameters of 2.7 m. This area was located in an alluvial savanna of the Arauca Department. We sampled 0,1 ha plot by setting 10 transects (50 x 2 m each) to survey all woody and herbaceous plant species. It was found 849 individuals from 29 families, 36 genera and 40 species. Based on their attributes such as the tree diametric distribution and sociological aspects, the “zural” forest does not seem appropriate for wood commercial extraction, but it is like... Mehr ...

We described the structure and floristic composition of a zurales forest with earth-mounds presenting average heights of 1.36 m and average diameters of 2.7 m. This area was located in an alluvial savanna of the Arauca Department. We sampled 0,1 ha plot by setting 10 transects (50 x 2 m each) to survey all woody and herbaceous plant species. It was found 849 individuals from 29 families, 36 genera and 40 species. Based on their attributes such as the tree diametric distribution and sociological aspects, the “zural” forest does not seem appropriate for wood commercial extraction, but it is likely to provide regulation ecosystem services. From the recorded species, three were notable; Sarcoglottis acaulis (Sm.) Schltr (Orchidaceae), considered a new record for the Arauca department, and Guapira cf. pubescens (Kunth) Lundell (Nyctaginaceae) and Pouteria cf. stipitata Cronquist (Sapotaceae) probably new records for the Colombian flora. ; Se determinó la composición florística y estructural de un zural boscoso con montículos de en promedio 1.36 m de altura y 2.7 m de diámetro localizado en la llanura aluvial del municipio de Arauca. Se muestreó un área de 0.1 ha con diez transectos de 50 x 2 m para estudiar vegetación leñosa y herbácea. Se registraron 849 individuos de 29 familias, 36 géneros y 40 especies. Por sus características de clases diamétricas y aspectos sociológicos del zural boscoso se considera que este tipo de bosques no podría ser usado con fines de extracción de madera a gran escala y posiblemente los servicios ecosistémicos que provee son de regulación. De las especies registradas se destacan: Sarcoglottis acaulis (Sm.) Schltr (Orchidaceae), como nuevo registro para el departamento de Arauca; Guapira cf. pubescens (Kunth) Lundell (Nyctaginaceae) y Pouteria cf. stipitata Cronquist (Sapotaceae), como posibles nuevos registros para Colombia.
