Abstract

The study area is located in the River Negro Parroquia Baños County. Tungurahua Province. is a influence area of the Sangay National Park, located. A: Mountain chain Charm. 1730 m.. B: The 1.380 m„ C: Gallery of Pastaza river. 1.450 m., coordination approx 78*13”W01°25'S , in forest types of Lower Moutam Evergreen Forest Field wot* was done June 1999 and May 2000. In each, we used the transects methodology of 0.1 Ha. for species i 10 cm of DAP. we herborizó all the species everything was deposited at the herbarium Alfredo Paredes (OAP). under catalogue Cerón ef al. 38000 - 41000. To anahze the information we used the Similarity and Diversity Index. In the locality A. we found 94 individuals. 44 species, the more frecuent are Sauraula pralnlana var. pastazana Chrysophyllum vanezuelanense and Dyptiocaryum lamarckianum In the locality B. 144 individuals. 55 species, the more frecuent are Otobe parvltolia. Cordla cf cymosa y Oreopanax grandifolius Locality C 154 individúala. 62 speoes. the more frecuent are: Turpin la occldentalls Psychotria flavlflora and Sorocea stelnbachll The beta diversity is 144 speoes The Diversity Index is A« 19.7. B= 18 7. C * 26 6. the interpretation *i the three cases, are dose dnrerse moderately The Sirmhty is. A-B= 14.1% . A-C» 3% and B-C« 8%. that shows that the 3 plots in the area are flowering different The 3 localities of Black Ri- 2 Cerón: Diversidad, rio Negro ver. shuw disturb forest spots, similarity diverse to forest preserved better, with 2-3 Km of distance between their llowenng composition is different, their diversity is median, the forest present Andean and Amazonian species. It determine a new vegetable formation to the country
