Supervivencia y desarrollo de dos especies de Pinus en una reforestación de la Región Montaña de Guerrero

Forest ecosystems are essential for the planet; however, they prone to anthropogenic disturbance. To counteract this trend,restoration practices such as reforestation used, in order recover degraded areas. The objective of study was evaluatethe development and survival a Chinameca, Atlamajalcingo del Monte, Guerrero. A plantation with species ofPinusayacahuite Pinuspatula carried out 784 m² plot, three-bolillo design at 2 m distance between plants,these were monitored every two months from establishment experiment. total 150 plants established threeblocks 25 seedlings per species. Survival evaluated 73 days until completing 257 variables basal diameter(mm), height (cm) crown area (m). overall average 79.99%; P.patulapresented 85.33% whileP.ayacahuiteonly registered 74.66%. All obtained submitted analysis variance (ANOVA) by speciesafter 8 months, where only significant differences found P.patula reached 35.71 cm,while P.ayacahuite 26.86 cm. It is concluded that suitable implement activities region.
