A floristic composition of the riparian forest in La Laguneta's microwatershed, Pueblo Nuevo municipality, Estelí

Abstract

The study was conducted in the watershed La Laguneta, site located in the municipality of Pueblo Nuevo, Estelí department, in order to assess the species composition of riparian forest. The research was conducted in three stages: the first involves the recognition of the study area, the second forest inventory in the riparian forest and the third analysis of the collected information. The collection of information is done through a systematic inventory on plots of 10 m² on a transept parallel to the banks of the river. The total number of plots were 23, where each took all trees greater than 10 cm dbh and within this stood a 1 m² subplot to inventory all the plants under 10 cm in diameter. We calculated the Shannon diversity index and Simpson to the top, middle and lower watershed. he study shows greater diversity in the upper and lower in the bottom of the site. In the inventory of trees over 10 cm were found 31 species in 21 plant families represented projecting the Mimosacea (6), for natural regeneration found 12 species in 8 plant families represented. A total of 300 trees per hectare found of which most belong to 10-19.9 cm diameter classes that are most representative and 27.0915 m²/ha basal area which is found in greater concentration in the categories of 50-59.9 and > 60 cm. There is environmental degradation due to deforestation in the lower due to agricultural activity. In the same study found that the top is the least affected by agricultural activities. This study was one of several Bachelor theses, funded by the project UNA/CARE/MARENA-PIMCHAS.
