Study of the diversity and floristic composition of a forest in the C.P. El Triunfo, San Ignacio – Peru

Abstract

The objective of this research work is to study the diversity and floristic composition of a forest in the C. P. El Triunfo, Huarango district, San Ignacio – Peru. The research project was developed in two plots of one hectare each, in a primary forest in the C. P. El Triunfo. Within the one-ha plot, 25 subplots were delimited, where arboreal and arborescent individuals with DBH ≥ 10 cm were recorded. The results achieved were the following: A total of 570 individuals were inventoried, identifying 20 species distributed in 12 botanical families; Licaria triandra (Sw.) Kosterm was the species with the highest number of individuals, also this species was the one with the highest IVI and the Lauraceae family was the one with the highest IVIF. The predominant diameter class was between 10 to 20 cm DAP, registering 215 individuals (PI) and 193 individuals (PII); For both plots, a slight absence of species uniformity is notable due to obtaining values close to zero for the Pielou uniformity index; The mixing coefficient for PI was 0.0614 and for PII it was 0.0578. The forest evaluated in this study has low biodiversity with a notable slight absence of species uniformity, which is concluded to be due to the intervention resulting from anthropogenic activities.
