Not Seeing the Forest for the Trees: The Oversight of Defaunation in REDD+ and Global Forest Governance

Background

REDD+ (Reducing Emissions from Deforestation and Forest Degradation) aims to mitigate climate change by preserving forest carbon stocks. Although REDD+ focuses mainly on reducing deforestation, it largely ignores defaunation—the loss of forest wildlife caused by unsustainable hunting. Many tropical forests suffer from "empty forest syndrome," where hunting removes large frugivores and seed dispersers, disrupting seed dispersal and carbon sequestration. This study highlights how REDD+ policies overlook the ecological role of forest fauna and argues that neglecting defaunation threatens the long-term success of forest conservation.

Roles of indigenous women in forest conservation: A comparative analysis of two indigenous communities in the Philippines

Background

This study examines the roles of indigenous women in forest conservation in Nueva Ecija, Philippines: the Ikalahan-Kalanguya of Caraballo Mountain in Carranglan and the Dumagat women of Mount Mingan in Gabaldon. These communities contain the highest number of indigenous people living in or near the forest in the province and have retained indigenous forest preservation practices. Historically, people have considered indigenous peoples in the Philippines, including women, protectors of the environment. However, specific studies focusing on the direct contributions of indigenous women to forest protection are lacking.

Synergistic Effects of Seed Disperser and Predator Loss on Recruitment Success and Long-Term Consequences for Carbon Stocks in Tropical Rainforests

Background

Defaunation—the loss of animal species due to hunting, habitat destruction, and other human activities—affects tropical forests profoundly. Large frugivores play a key role in seed dispersal, while seed predators influence recruitment success and plant population dynamics. Previous studies focus mainly on how defaunation impacts seed dispersal but often overlook the role of seed predators and potential compensatory ecosystem effects. This study examines how losing both seed dispersers and seed predators simultaneously affects tree recruitment and long-term carbon storage in tropical forests.

Fungi and Insects Compensate for Lost Vertebrate Seed Predation in an Experimentally Defaunated Tropical Forest

Background

Defaunation disrupts key plant-animal interactions such as seed dispersal and seed predation, triggering cascading effects on plant regeneration, species composition, and carbon storage. While past studies emphasize the negative consequences of losing vertebrate seed dispersers and predators, it remains unclear whether other organisms like fungi and insects can compensate for these losses. This study investigates whether non-vertebrate predators offset the decline of large vertebrate seed predators in a tropical rainforest.

Size-Related Differential Seed Predation in a Heavily Defaunated Neotropical Rain Forest

Background

Defaunation, driven by hunting and habitat loss, disproportionately affects medium and large mammals, often leaving behind a residual community dominated by small rodents. This shift in mammal communities can alter seed predation dynamics and impact forest regeneration. In heavily defaunated areas like Los Tuxtlas, Mexico, small rodents have become the primary seed predators. This study investigates whether seed predation patterns differ based on seed size in a highly defaunated forest. Specifically, it examines whether small rodents preferentially consume small seeds while large-seeded species escape predation, potentially influencing seed germination and plant recruitment.

Drivers and spatial patterns of avian defaunation in tropical forests

Background

Tropical forests harbor an immense diversity of bird species, but hunting and wildlife trade are driving widespread declines in bird populations. Unlike habitat loss, hunting often occurs in seemingly intact forests, making its impact more difficult to detect. Birds are harvested for both subsistence (food) and commercial purposes (pet trade), but the spatial extent and drivers of avian defaunation remain poorly understood. This study aims to assess the factors influencing bird population declines and map defaunation patterns across tropical forests.

Defaunation affects carbon storage in tropical forests

Background

Tropical forests play a critical role in global carbon storage, holding approximately 40% of the Earth's terrestrial carbon. While deforestation, logging, and climate change are well-documented threats to these forests, the impact of defaunation (the loss of large frugivorous animals due to hunting and habitat loss) has been largely overlooked. Many large-seeded hardwood trees rely on large vertebrates for seed dispersal, and their decline could significantly affect forest composition and carbon storage.
