Diversidad de especies arvenses en plantaciones de Tectona grandis (teca) en diferentes estadios temporales de 9 a 18 años en la época seca en la zona de los cantones Balzar y Palenque, año 2018.

The objective of this project is to identify the diversity of weed species in plantations of Tectona grandis (teak) in different time stages from 9 to 18 years in the dry season in the area of Balzar and Palenque cantons, year 2018, where a total of 47 species in the 16 Sampling Units in the four study sites. Qualitative and quantitative data were taken such as common name, description of the individual, number of individuals per species and the coordinates of each site, for the diversity analysis parameters were taken: frequency, abundance, the Jacard, Shannon Indexes were also used and Simpson, in addition to the cluster analysis that measured the interactions between the different sampling units. There were 2634 individuals in 47 species, of which the most abundant was Acalypha alopecuroides Jacq., they were grouped into 33 families and 37 genera. The Shannon Index determined a high diversity in all the sampling units while the Simpson Index determined an average diversity for all the sampling units.
