From Pest to Profit: Exploring Market Forces as a Tool for Managing Invasive Species

WWF's report explores using market forces to manage invasive species, specifically focusing on the development of a framework to evaluate the ecological and business viability of such efforts. It highlights a proof-of-concept project involving the processing of invasive carp for pet food via the company IGNIZA, which utilizes a former limestone mine to reduce energy costs. The report provides detailed ecological and business checklists to prevent unintended consequences, such as incentivizing the spread of invasive species, and applies these to case studies of invasive carp and black locust trees.

• Invasive species represent a severe global threat, contributing to 60% of global extinctions and incurring annual costs estimated at $423 billion, with these costs increasing fourfold every decade.
• WWF has developed a 'Market Uses for Invasives' framework consisting of ecological and business checklists to ensure that market-driven harvesting provides environmental benefits without causing further harm, such as incentivizing the propagation of the species or harming native species through bycatch.
• A primary bottleneck in using invasive carp for pet food has been the lack of large-scale processing; to address this, the company IGNIZA has established a 'Fishility' processing center in a former limestone mine in the St. Louis region.
• The use of a former limestone mine for carp processing provides significant energy savings due to a constant year-round temperature of 58°F, which could potentially reduce total emissions from processing, transport, and storage by up to 40 percent.
• Applying the framework to invasive carp suggests that medium levels of harvest can limit their spread, decrease population density, and improve local biodiversity, while filling a gap in the pet food market where demand for protein is outpacing the supply of animal byproducts from human consumption.
• The framework's application to black locust trees indicates that while they offer high-value, rot-resistant hardwood for construction, market creation for honey production could be counterproductive by incentivizing the protection and increase of tree populations.
