Logging in Dry Chaco Forests Not Harming Key Tree Regeneration.
Logging intensity in the Dry Chaco forest can impact the structure of the canopy and understory, affecting the regeneration of valuable timber species like Schinopsis lorentzii and Aspidosperma quebracho-blanco. A study across 13 sites with different logging histories found that canopy cover and shrub basal area decreased with logging intensity, while shrub stem density remained unchanged. The density of A. quebracho-blanco saplings was positively related to shrub stem density, suggesting a potential positive impact of logging on its regeneration. However, S. lorentzii regeneration was not affected by logging intensity. The results indicate that dry Chaco forests may be resilient to logging practices, with canopy cover and shrub basal area potentially recovering after a long rest period. It is suggested that logged forests need decades to fully recover their structure.
