The islands of Ipipiri (the Bay of Islands) were cleared of invasive rodents and mustelids in 2009. Since then, there have been over 50 incursions of predators to the island group. The Department of Conservation invited myself and others to visit the islands last week in anticipation of another bumper summer of cat, rat and…

For the last three years I have been travelling and collaborating across Brazil to increase awareness of the role of invasive alien species. As my trip to the Pantanal comes to an end so too does this time working in Brazil. On the last morning with Projeto Tamanduá we wake early to capture a giant…

Like all science, invasion biology depends on clear and strict definitions. The concept of a native invasive species therefore sounds implausible, but is exactly what I have found on Fernando de Noronha. Without consistent definitions, scientists can talk at odds over one another, not realising they are talking about different things. Examples of important distinctions…

The Amazon is not typically a place one thinks of as insular, but the Parque Nacional de Anavilhanas in Brazil has over 400 islands in the Rio Negro. My visit to the national park coincided with the end of the dry season, when the river is at its lowest – up to a staggering 10…

I was visiting to understand how the community feels about proposals to eradicate introduced mammalian predators from the entirety of the island – Predator Free Rakiura. The eradication of…

Plans to manage pest species are becoming increasingly larger in scale and ambition. The outcomes of such programmes can have just as important impacts on the resident human communities as the plant and animal communities. Today in New Zealand protests and arrests took place outside the Brook Waimarama Sanctuary, after a legal appeal to prevent…

Last summer after visiting Great Mercury Island I had the brief opportunity to visit nearby Slipper Island off the coast of the Coromandel. With only a weekend on the island, I set out to perform a ‘bioblitz’ terrestrial fauna survey. I was particularly intrigued about reports of Polynesian rats on the island, as this rat…

This month two major invasive species meetings are being held in Britain. First is the Island Invasives conference in Dundee, and later in the month a symposium on the macroecology of alien species. Each meeting will give a unique perspective on the science and management of invasive alien species around the world. The Island Invasives…
