Longitudinal and radial variability of the physical properties of Escallonia pendula wood in andean premontane ecosystems

Abstract

Premontane ecosystems play a crucial role in biodiversity and the provision of ecosystem services, but they have been studied less than other ecosystems. Escallonia pendula, a native species of these ecosystems, stands out for its potential in soil stabilization and for its contribution to the regeneration of degraded areas. This study evaluated the physical properties of E. pendula wood and its longitudinal and radial variability to determine its potential as a timber resource in Andean premontane ecosystems. Sampling was conducted in a premontane humid forest in northeastern Peru, specifically at Fundo Tesoro Perdido. Three representative trees were selected, and wood samples were collected from different trunk heights and radial positions. The physical properties analyzed included moisture content, density, shrinkage, and dimensional stability, following Peruvian Technical Standards. Results showed that, along the longitudinal axis, basic density was higher in the basal section, while moisture content was greater in the central section. No significant differences were found among radial positions for the evaluated physical properties, indicating high uniformity in wood characteristics across the trunk radius. The wood of E. pendula was classified as medium-density and exhibited good dimensional stability. These results suggest that E. pendula has high potential for use in the timber industry, particularly in applications requiring dimensional stability and moderate strength, such as furniture manufacturing and lightweight structural components. This study provides a foundation for the sustainable use of this species in industrial applications and ecological restoration projects.
