Recommendations for reducing environmental impact of pest mammal monitoring in New Zealand

The introduction of pest mammals and plastic pollution are two significant contributors to biodiversity loss in New Zealand (NZ). My research aims to minimise both these issues by offering a solution to pest mammal monitoring that is more environmentally friendly. Despite NZ’s reputation as a ‘clean, green’ country – we have trouble managing waste, leading to challenges in the fight against climate change. We have already banned plastic bags, and are expanding the ban to include all single-use plastics - targeting items that commonly end up in landfills and pollute soil, waterways and the ocean. It is estimated that more than 2 billion single-use plastics will be removed from our landfills yearly. By phasing out unnecessary and problematic plastics, we will reduce landfill, improve recycling systems and encourage reusable or environmentally responsible alternatives. While the NZ government focuses on removing single-use plastic from many large sectors, such as hospitality, smaller less-recognised sectors, such as conservation and biodiversity, are often overlooked. Instead of waiting until the spotlight turns to the single-use plastic used in pest monitoring and control, we should begin phasing out single-use plastic ourselves. Currently, the most commonly used pest mammal monitoring options are plastic. New biodegradable, environmentally friendly pest mammal monitoring equipment options can be designed and compared with traditional plastic options to determine if they can become the new industry standard. I will also be investigating potential by-products from other larger sectors that could potentially be used to create sustainable monitoring equipment. Complementary research is being done to develop biodegradable traps and long-life biodegradable lures; however, more effort is required for monitoring equipment. Throughout this study, I will conduct fieldwork that looks at encounter and interaction rates of plastic and biodegradable detection devices – with both free-ranging and captive animals. Current ...
