Tag hinzufügen | Zusammenfassung: | The research is part of the project called "Monitoring Site and Experimentation, Podocarpus National Park (PNP)" proposed by the Consortium for Sustainable Development of the Andean Ecoregion (CONDESAN). It was carried out on the moor ecosystem of sector Cajanuma, PNP, 3 200 msnm (704000 UTM - 9545455 UTM), was developed during the months of May to July 2015. The monitoring area established for the project comprises 1 260 m2, within which three blocks of 420 m2, made up of 10 experimental units of 36 m2, each experimental unit comprises four subunits of 9 m2 were delimited; within which 30 quadrants of 1 m2 for florítico sampling, and 60 strips of 0,1 m2 for estimating biomass plant was installed. Regarding the floristic composition, 1 367 individuals belonging to 32 families, 49 genera and 66 species were recorded. The most diverse families are Asteraceae, Ericaceae and Melastomataceae; the species with the highest number of individuals are: Tillandsia aequatorialis with 47 000 ind/ha, Hypericum lancioides with 35 333 ind/ha, and Vaccinium floribundum with 35 000 ind/ha; in concordance to diversity index Shannon-Weaver, the floristic diversity in this ecosystem is high. Furthermore, an average value of the total plant biomass (dry weight) equals 14,76 t/ha ha was recorded; aboveground biomass contributes with 9,35 ind/ha; and necromass with 5,42 ind/ha. Aboveground biomass category includes subcategories vascular plants and bryophytes; where vascular plants provide 4,96 ind/ha and bryophytes 4,39 ind/ha. According to data obtained in this research, the moor ecosystem is important not only for the high floristic diversity, it is also because of the high amount of biomass that is recorded, whose estimate is crucial for quantifying carbon stocks, representing a huge opportunity to exploit the marketing potential of carbon credits as a tool to promote conservation of this ecosystem. |
