CARACTERIZACIÓN DE UN BOSQUE DE QUEÑUAL (Polylepis spp.) UBICADO EN EL DISTRITO DE HUASTA, PROVINCIA DE BOLOGNESI (ANCASH, PERÚ)

Abstract: ResumenLos bosques del género Polylepis, a pesar de cumplir un rol central en la ecología de los Altos Andes, constituyen en la actualidad uno de los ecosistemas más vulnerables de Sudamérica. Sin embargo, la percepción de su valor está cambiando y se está reduciendo su deforestación e incentivando su conservación. Con el objetivo de caracterizar la población de dos especies de Polylepis (P. reticulata y P. sericea) presentes en el bosque de la microcuenca de Paria -distrito de Huasta, se muestreó 109 parcelas… Show more

“…In the light of the findings, it is possible to establish the criterion that the different Polylepis species are specifically adapted to the particular conditions of temperature, humidity and altitudinal gradient. The high and negative correlation between the water potential and the altitudinal gradient obtained for the plants in each forest reflects the great capacity of adaptation of the Polylepis individuals to the extreme climate changes that occur at high altitudes in the central sierra of Peru and Latin America, due to their presence from Venezuela to the south of Chile (Castro and Flores, 2015).…”

“…The Polylepis canoi forests of the Tasta and Nahuin localities were characterized by much taller and thicker trees compared to the two other localities. It could be argued that at these localities the trees experience less severe growth conditions, with relatively higher temperatures and precipitation levels (Castro 2014;Mendoza 2005). The forests of P. canoi were characterized by presenting a tall and dense structure limiting the amount of light in the forest understory and inhibiting the development of young seedlings (Morales et al 2017), unlike a forest of P. besseri in which the absence of regeneration is due to a high degree of human impact (Martínez and Villarte 2009).…”

“…Previous studies have shown that the structural and spatial heterogeneity of treeline habitats is related to elevation, latitude and topography (Bader and Ruijten 2008;Bunyan et al 2015). Polylepis subsericans and P. incana evidence a relationship between the location of forests associated with topographic features which varies in relation to elevation (e.g., Coblentz and Keating 2008;Toivonen et al 2018), whereas in other species such as Polylepis flavipila, P. reticulata, P. incana and P. australis the population structure and density have been characterized, demonstrating the importance of this information to know the current state of the forests and propose conservation actions (Camel and Castañeda 2018;Castro 2014;Cierjacks et al 2008;Pacheco 2015;Renison et al 2011). In disturbed forests, Kessler et al (2014) found no saturation of tree height related to the increase of the diameter, since cutting and extraction of firewood affected the largest trees, altering the dasometric and spatial structure of the forests.…”

“…Están distribuidos de manera reducida en laderas y quebradas (Trinidad & Cano, 2016;Segovia-Salcedo et al, 2018), encontrándose la mayor cantidad de especies en los Andes del sur de Perú (Mendoza, 2005). Cumplen un papel fundamental en la ecología de las zonas altoandinas, estableciéndose como ecosistemas de gran importancia (Castro & Flores, 2015;Trinidad & Cano, 2016) y forman parte del hábitat de la flora y fauna (Hurtado et al, 2018), por lo que existe una pluralidad de aves especialistas y variedad de especies asociadas, que dependen de estos bosques (Huaira et al, 2019). Así mismo brindan servicios ecosistémicos directos como combustible, medicina natural y material para construcción (Hurtado et al, 2018); del mismo modo, almacenan carbono comportándose como sumideros para hacer frente al cambio climático (Eyzaguirre, 2015).…”

“…Así mismo brindan servicios ecosistémicos directos como combustible, medicina natural y material para construcción (Hurtado et al, 2018); del mismo modo, almacenan carbono comportándose como sumideros para hacer frente al cambio climático (Eyzaguirre, 2015). En la actualidad constituyen los ecosistemas más vulnerables, por la constante actividad antropogénica, la deforestación y el pastoreo (Zutta et al, 2012;Castro & Flores, 2015;Caiza et al, 2018;Rossi et al, 2018;Guzmán et al, 2021). A pesar de la importancia que poseen como recursos necesarios para la conservación de la biodiversidad y la regulación hídrica, existe poca información sobre su fenología y no se han implementado estrategias de conservación y restauración (Zutta et al, 2012;Franco et al, 2021;Guzmán et al, 2021).…”
