Using Tree shelters to improve the initial performance of huisache (Vachellia schaffneri) plants in reforestation projects

Abstract

Objective: To evaluate the impact of tree shelters on the survival and early growth of huisache seedlings (Vachellia schaffneri (S. Watts) Hermann) in semiarid regions featuring soil conservation structures.

Design/Methodology/Approach: The experimental design comprised two planting conditions: (1) within areas where soil was retained by conservation works, and (2) outside such structures. These were combined with two protection treatments: (1) seedling protection using light-transmissive polyethylene tubes, and (2) no protection. Survival and growth metrics were monitored during the first year post-planting.

Results: While the protective tubes did not significantly affect survival rates, they markedly reduced herbivory by defoliating insects. Additionally, seedlings with protection exhibited enhanced height growth. Although the protective effect on diameter growth was less pronounced, it was notably significant under the planting condition outside the soil conservation structures. Defoliation, while not impacting survival, had an adverse effect on seedling growth.

Limitations/Implications: These findings carry practical significance for reforestation initiatives aimed at rehabilitating degraded semiarid landscapes.

Findings/Conclusions: Tree shelters enhance the initial establishment and growth performance of seedlings in reforestation efforts within semiarid environments
