Tree density by development stage in the “El Carrizal” wathershed of Tapalpa, Jalisco: Tree density by development stage in the “El Carrizal” wathershed of Tapalpa, Jalisco
The Tapalpa forest presents an abundance of pine trees in the juvenile stage of regeneration and sapling, but this amount progressively decreases in the successive stages, when the trees show larger dimensions and take up more space to grow. However, it was unknown how much the loss was and how much it reached the maximum size. The objective was to quantify the grove, the individual space, the separation between trees and their decrease. The stages were classified according to the normal diameter and the sites were classified as excessive, recommendable, sufficient and poor density. Frequency distribution, loss, spacing, and distance between trees were calculated using the Hart-Becking formula. During the development cycle, the loss was close to 90 % with a rate of 0.2 to 3 %, presenting a cumulative of 60 % in the monte bravo and vardazcal stages. The recommended class began with 1 300 to 2 700 trees ha⁻¹ in the juvenile phase, with their respective spacing of 2.07 to 2.98 m, while the mature stage culminated with 150 trees ha⁻¹ separated at 8.77 m. The distance between trees is considered an auxiliary tool in thinning operations.
