The contribution of fire damage to restricting high mountain Polylepis australis forests to ravines: Insights from an un-replicated comparison

Abstract: High mountain forests are often restricted to ravines and much debate has existed on the explanations of this distribution, with arguments ranging from abiotic site conditions being more favorable in ravines to there being reduced herbivory or reduced fire frequency and damage in ravines. We aim at understanding the contribution of fire damage and provide data to help test the hypothesis that fires are less damaging and that trees recover faster in ravines as compared to ridge sites. We evaluated crown damage,… Show more

“…While the study must be considered as a starting point that requires further exploration, the prehistoric record of Quebrada del Real 1 indicates that the maintenance of habitat dominated by P. australis trees to stop erosion is critical to the conservation of the upper mountain grassland range and their headwater catchment that provide water to modern cities located basin down. Thus, the zooarchaeological data of C. viarapaensis support the immediate need to achieve more control of modern livestock densities to prevent fires, soil erosion and biodiversity losses under semi-arid conditions as it was proposed by many researchers (Renison et al 2004;Renison et al 2010;Alinari et al 2015;Cingolani et al 2015;Chartier et al 2016;Argibay & Renison 2018;Giorgis et al 2020), mostly when the application of these management policies displayed positive results in the Parque Nacional Quebrada del Condorito (Fig. 2b).…”

“…The loss of soil probably caused the extinction of C. viarapaensis, mainly when it was a rodent strongly adapted for digging (De Santi et al 2020). Several studies report the aggressive effect of the traditional method of livestock production on soil, whose advance leaves behind exposed bedrock areas (Renison et al 2010;Cingolani et al 2013;Barros et al 2014;Alinari et al 2015;Chartier et al 2016;Argibay & Renison 2018;Giorgis et al 2020). Under such environmental changes, Ctenomys populations that could not move to another location disappeared as happened with C. viarapaensis and as it would be occurring today with C. osvaldoreigi (Torres & Tamburini 2018;Mora et al 2019).…”

“…Como hay una única parcela por tratamiento, se trata de un muestreo sin repeticiones. No obstante, este tipo de análisis estadístico se considera adecuado para estudios de caso; por esta razón, nuestros resultados están acotados a la situación analizada, sin poder extrapolarlos (Hargrove and Pickering 1992;Huber and Trecamán 2004;Alinari et al 2015).…”

“…En aquellos bosques cuyas plantas leñosas suelen rebrotar después de los incendios, el fuego no produce cambios sustanciales en la composición de especies, pero sí en la fisonomía, debido a la drástica reducción de la biomasa arbórea que favorece la proliferación de hierbas y de arbustos (Türkmen and Düzenli 2005;Giorgis et al 2017). Sin embargo, un mismo incendio puede afectar de distinta manera a ejemplares de una misma especie leñosa, dependiendo, entre otras cosas, del tamaño de los individuos y de las condiciones del microambiente (Marañón et al 2004;Alinari et al 2015;Landesmann et al 2015). De este modo, los tejidos de algunos árboles resultan muy dañados, mientras que los de otros pueden sufrir menos daño.…”

“…De este modo, los tejidos de algunos árboles resultan muy dañados, mientras que los de otros pueden sufrir menos daño. Los individuos más dañados perderán más biomasa aérea y tendrán menos probabilidad de sobrevivir al fuego o, si sobreviven, tardarán más tiempo en recuperar su biomasa en comparación con los individuos menos dañados (Cable 1965;Renison et al 2002;Ordoñez et al 2005;Alinari et al 2015). Por estas razones, el tamaño de los árboles y las condiciones del microambiente, al influir sobre el daño de los tejidos, pueden afectar la velocidad a la cual el bosque recupera su estructura anterior al fuego.…”
