Characterization of natural regeneration in the permanent monitoring plot of the communal forest of the Lejía hamlet, Shamboyacu district, San Martín Region, Peru

Abstract

The purpose of the study is to characterize the floristic composition and the ecological variables of natural regeneration in the permanent plot of the Communal Forest of Caserío Lejía, Shamboyacu district, San Martín region, through the methodology of the Amazon Forest Inventory Network and the modified design. Camacho in 2000 and BOLFOR in 1999. 252 individuals were obtained distributed in 50 tall poles, 137 low poles, 48 seedlings and 17 seedlings, grouped into 29 families, the most abundant being Melastomataceae with 18.15%, Lauraceae with 11.69%, Rubiaceae with 10.89%, Fabaceae with 7.26%, Myristicaceae with 6.28% and Meliaceae with 6.45%, and a total of 104 species, of which the most abundant Qualea acuminata with 7.14%, Micropholis guyanensis with 476%, Sloanea sp. with 3.97%, Virola elongata with 3.57%, Miconia cf. bubalina and Protium tenuifolium with 3.17%, respectively. Regarding the ecological variables in low and high saplings, quality 3 prevailed, that is, 62.04% had curved stems and 58% had serious defects. The crown illumination category was not direct at all, it was 78.10% for low poles and 70% for high poles, highlighting the shaded plants vertically and laterally. The shape of the cup in low poles was very poor with 43.80%, in high poles it was tolerable with 40%, that is, irregular, despite the fact that they have the ability to improve if they are given space. The infestation of lianas in low latizal was classified in the quality without climbers with 81.75%, and in high latizal it obtained 60% in individuals free of climbers.
