Forest enrichment experiences in secondary forest in the watershed “The Padmi”, Zamora Chinchipe-Ecuador
Keywords:
Growth, plantation, forest enrichment, conservationAbstract
This research contributes to the management of suitable and reliable species for forest enrichment, which impacts the management of secondary and primary forests, forest plantations, according to physiographic and ecological characteristics of southern Ecuadorian Amazon. Growth potential was assessed in 195 plants: 75 of Cedrelinga cateniformes, 45 of Cedrela odorata and 75 of Schizolobium parahyba through analysis of forest variables such as: survival, total height, diameter at breast height, basal area and volume. Likewise, analysis of descriptive statistics, analysis of variance (ANOVA) and comparison tests (Tukey) with a significance level of 0,05 % error was made to demonstrate the effect of the growth potential that developed the three forest species at 11 years of age in secondary forest. The results indicates that from the three species evaluated Cedrela odorata with 85 % of survival is a species of slow growth compared to the other two species tested. Furthermore, it was found that Schizolobium parahyba with 84 % of survival has an enormous potential due to its high growth in height, plant quality, excellent form of stem, goblet and its ability to perform a high volume per unit area. It was also noted that Cedrelinga cateniformes despite having the lowest survival rate (64 %) of the three species, has high growth rate in height and with high economic value is an optimal species to develop forest enrichment systems in secondary forests.Metrics
