Clean Boats, Clean Ports - A Framework to Protect Pacific Island Countries and Territories from Invasive Species
SPREP Publications, Island and Ocean Ecosystems, BRB
Available Online

Secretariat of the Pacific Regional Environment Programme

2023
The clean boats, clean ports framework is a Pacific Regional Invasive Species Management Support Service (PRISMSS) Protect our Islands (POI) initiative to enable countries to better secure international entry ports that are gateways to priority domestic destinations. This Battler Series publication supports the prevention of the spread of invasive species among islands within countries. The document outlines a flexible framework that recognises the diverse situations in Pacific island countries and territories and that capitalises on existing strengths, while highlighting achievable and aspirational targets. This publication is part of a collection of Battler guides on preventing the spread of invasive species in the Pacific region. For an introduction, read the Battler publications Protect our islands with biosecurity and Catch it early: invasive species early detection and rapid response. This guide is targeted for decision-makers prioritising improvements to prevent invasive species arriving, establishing, and spreading, to guide the implementation of targeted enhancements. The guide aligns with many aspects of the regional Guidelines and particularly C1. Biosecurity – Preventing the spread of invasive species across international or internal borders.

Biodiversity is a term that describes the number and diversity of the different plants, animals, and other living things within our environment. Biodiversity is a key factor in natural resilience to the impacts of environmental change. All species contribute to environmental resilience, including those that are naturally common and those that are rare. Natural biological communities have evolved over thousands or millions of years and have resulted in adaptations to local conditions that make these species resilient to natural environmental change. This community of native species contributes to ecosystem functioning and together provides the ecosystem services that we rely on. These services include provisioning (such as food, fuel, raw materials, and medicines), regulating (such as provision of clean water and air, climate regulation and flood protection, waste decomposition, and biological pest and disease control), supporting (such as nutrient cycling), and cultural services (such as spiritual and heritage value, recreation, and science). When ecosystems are disturbed or disrupted, due to habitat modification, overharvesting, or invasive species, their function is affected, the benefits they offer decline, and resilience to further change is reduced. In this time of unprecedented global environmental change, protecting biodiversity is more important than ever to ensure we can retain the benefits of the natural world on which all our lives depend.

There is much debate surrounding the impact of feral cats (Felis catus) on wildlife. Conservancies areusually areas where indigenous flora and fauna are protected and aliens excluded or managed. The University of KwaZulu-Natal’s Howard College campus (HCC) is an urban conservancy containing feral cats that are presently not managed, and little is known about their ecology and behaviour. Consequently a feral cat population census was conducted, and their home range investigated. Estimates of the overall campus feral cat population numbers ranged between 23.4–40.0 cats/km2 with a minimum of 55 identified as resident. They were not randomly distributed in the study area, with spacing patterns being related to resource availability. Home range area and core distribution of eight radio-collared cats were determined over 13 months. Total home range areas were relatively small, with considerable overlap between them. Home ranges were clustered in areas with permanent feeding stations and these were also within the cats’ core ranges. Supplemental food resources appear to have a major influence on numbers, home and core range area, and behavior of cats. It is clear that cat densities grow to high levels with reliable and abundant food supply and only ad hoc sterilization. This has implications for their management in the HCC urban conservancy.
