Assessing the sustainability of the harvest of animals can be done by obtaining data from processing facilities and establishing that vital attributes of the harvested animals (e.g., size, age structure, sex ratio) do not change over time. This model works if the traders operate in a free market without any regulations on what can be harvested, processed or exported, and when harvest methods and harvest areas do not change between assessment periods. Several studies assessed the harvest effects…

Trade in Southeast Asian Box Turtles from Indonesia: Legality, Livelihoods, Sustainability and Overexploitation

Southeast Asian box turtles Cuora amboinensis are distributed in mainland Southeast Asia and throughout most of insular Southeast Asia and are often found in habitats shared with humans. In the 2000s



Jungle Giants: Assessing Sustainable Harvesting in a Difficult-to-Survey Species (Python reticulatus)

The study underpins the need for robust science to inform wildlife trade policy and decision-making, and urges wildlife managers to assess sustainability of difficult-to-survey terrestrial wildlife by drawing inferences directly from the harvest itself.

The international trade in live reptiles impacts significantly more species, with international trade documented for at least 642 taxa, and the largest trade in volume for all uses of reptile species and included 75 species from 2000 to 2017.

Challenges in Evaluating the Impact of the Trade in Amphibians and Reptiles on Wild Populations

The overcollecting of some species highlights the need to assess the trade and ensure that it is not contributing to declines in wild populations, and policy changes to acquire baseline biological information are urgently needed.

Global wildlife trade across the tree of life

The assessment underscores the need for a strategic plan to combat trade with policies that are proactive rather than reactive, which is especially important because species can quickly transition from being safe to being endangered as humans continue to harvest and trade across the tree of life.
