In late August 2026, Brazilian urban forestry efforts expanded to include stricter pruning regulations and advanced climate resilience strategies. In Araras, São Paulo, the Secretariat of Environment and Agriculture established that while certain formation and conduction pruning tasks do not require permits, ‘drastic pruning’—the removal of more than 30% of a tree’s canopy—is classified as an environmental crime punishable by a R$ 3,842.00 fine. Similarly, Quatro Pontes issued warnings against unauthorized interventions that could compromise tree stability and the vital ecosystem services they provide, such as air quality and temperature regulation.

Scientific and policy frameworks are also evolving to address extreme heat. Research continues to emphasize the cooling capacity of mature trees, which can reduce canopy temperatures by up to 3 °C; experts note that preserving one mature tree provides benefits equivalent to approximately 400 saplings. To support tree survival in compacted urban soils, specialists recommend specific irrigation and soil composition techniques. Furthermore, urban planners are increasingly adopting the ‘10-20-30 rule’—limiting the percentages of species, genera, and botanical families—to enhance biodiversity and prevent mass pest devastation.

These technical advancements support the proposed National Urban Arborization and Thermal Resilience Policy. This federal initiative seeks to mandate tree coverage targets in large cities and vulnerable neighborhoods, prioritizing shade infrastructure near schools and health centers while offering incentives to municipalities that achieve specific preservation and planting milestones.
