Ărboles del Santuario HistĂłrico de Machu Picchu: Monitoreo de diversidad y carbono a largo plazo
Get PDFUnderstanding how the richness, diversity, and carbon monitoring vary and are distributed through altitudinal gradients in Andean montane forests is essential to understand how these forests are adapting to global warming effects. Botanical explorations and general collections were carried out within the limits of the Historic Sanctuary of Machu Picchu in an altitude gradient of 1600 to 4200 m.a.s.l. Two permanent plots of 1.0 ha were established in the sectors of Intipunku (SHM â 01) at an altitude of 2,653 m.a.s.l and Kantupata (SHM-02) at an altitude of 3,200 m.a.s.l., with the standardized methodology of RAINFOR in 2013 and remedied in 2016. We updated the number of tree species for the Historic Sanctuary of Machu Picchu, 364 species are reported so far, this catalog includes all wild and cultivated species but also tree ferns and palm trees. In recent years, four new tree species have been described whose TYPE collections come from SHM forests: Ocotea alveatavan der Werff, Ocotea mollivillosavan der Werff (Lauraceae), Bunchosia cuscanaW.R. Anderson (Malpighiaceae), Ficus machupicchuensisC.C. Berg (Moraceae). In the two permanent plots, a total of 69 species were recorded in 1286 individuals. Individually in the SHM â 01 plot, 26 families, 36 genera and 45 species were recorded in 682 individuals; and in the SHM â 02 plot: 22 families, 28 genera and 31 species in 604 individuals. Stored aerial biomass was higher in the Intipunku sector (146 Mg ha-1) compared to Kantupata sector (101 Mg ha-1). Our research shows that the Andean forests of Machu Picchu provide important ecosystem services, and there is still much to do in terms of scientic research. The continued discovery of new tree species in the locality demonstrates the need for conservation to protect forests that support some of the highest levels of endemism in the world
