The Brazilian tropical forests are recognized for its astonishing biodiversity and its pivotal role in climate change mitigation. These forests are predominantly recognized in the Amazon and Atlantic Forest biomes, but they also extend expressive areas across Brazil’s Cerrado, Caatinga, Pantanal, and Pampa biomes. Each one hosting diverse forest ecosystems with unique biodiversity and playing critical roles in global climate regulation, carbon cycling, and ecosystem services. However, the rapid climate change accelerated by human activities is modifying the forest structure at unprecedented rates, leading to disruptions in forest functioning. In this context, permanent monitoring plots are indispensable for tracking these impacts over time, offering robust data on how forests are responding to changes in climatic conditions. Unfortunately, the distribution of long-term monitoring efforts across the forested regions within Brazil’s biomes remains highly uneven. The Amazon, as a globally renowned tropical forest, has been extensively studied and focal for research conservation funding, whereas forests in biomes like the Pampa and Pantanal remain neglected, despite their ecological importance. This symposium aims to summarise a comprehensive overview of the current state of long-term ecological research regarding to climate change in forests across all Brazilian biomes, bringing together experts and representatives from each biome. It will also explore the disparities in research focus and funding, discuss the challenges and opportunities in establishing and maintaining monitoring networks, and identify solutions to strengthen ecological studies across all biomes. Attendees will gain valuable insights into how different long-term monitoring projects improve our understanding of biodiversity, forest dynamic, functioning, and ecosystem resilience across diverse ecological and environmental contexts. The session will also encourage collaboration and networking opportunities to address unique challenges to each biome, ultimately aiming to strengthen Brazilian ecological research infrastructure and unify our understanding of its diverse ecosystems. This session is essential not only for researchers working in tropical forests but also for anyone interested in equitable and inclusive approaches to global conservation. By promoting dialogue, collaboration, actionable conservation strategies, and policy recommendations, this symposium emphasizes the importance of understanding distinct forests as interconnected and essential components of the planet’s ecological balance.
