Biz Bell is Senior Ecologist with Wildlife Management International Ltd (WMIL) and has over 20 years’ experience in island restoration, invasive species control and eradication, seabird research and conservation. Beginning her conservation career under the guidance of her father, Brian D. Bell, a pioneer in conservation and island restoration, Biz has managed four successful major rodent eradications in the UK (Lundy Island, Isle of Canna, St Agnes & Gugh and the Shiant Isles) and a further 20 invasive species (rat, mouse, rabbit and hare) eradications around the world. Many of these eradications have been on islands with communities or were privately owned and all were completed with the assistance of volunteers, partner agencies and with the support of communities and landowners. The recent successful operation on St Agnes & Gugh in the Isles of Scilly was the largest community-led rat eradication in the world. In addition to directing eradications, Biz has audited rodent control and monitoring programmes and investigated the feasibility of eradicating rats from islands around the world. Biz has also undertaken large-scale research projects into the population size, abundance, distribution, home range and impact of rats (particularly in relation to seabird populations and island ecosystems) and re-incursion probabilities for islands within the UK and around the world. Biosecurity and incursion strategies are also an area of Biz’s expertise that make up an important part of her work before, during and after invasive species eradication projects on islands. Not only working on invasive species, Biz has also undertaken one of the longest (21-year) seabird monitoring and research projects in New Zealand; determining population parameters and at-sea distribution of the black petrel.
