Dr. Piero Genovesi
Head of Wildlife Service
ISPRA (Institute for Environmental Protection and Research), Italy


Piero GenovesiPiero gained a Masters degree in 1989 and a PhD in 1993 in Animal Ecology at the University of Rome, carrying on research on carnivore ecology.

Since 1996 he has worked with the INFS (Italian Wildlife Institute - the Italian government research institute for conservation), focusing on carnivore conservation and alien species. He has coordinated several research projects (eradication and management of invasive alien species, patterns of invasions of mammals, economics of biological invasions, etc.) and worked closely with the Italian Ministry of Environment and with several international institutions (such as the Council of Europe, the European Commission, and the European Environmental Agency) to develop guidelines and policies on the management of alien species (he is a co-author of the European Strategy on Invasive Alien Species).

In 2000 he was nominated Chair of the European section of IUCN SSC ISSG, and in 2005 appointed Deputy Chair of ISSG. In this capacity he has coordinated many activities on invasive species, providing technical support to States and institutions in the field of invasive alien species management and for the development of policies on the issue.

At present Piero is Head of Wildlife Services with the ISPRA (Institute for Environmental Research and Protection, created by the Italian Government after the suppression of INFS)

Shyama Pagad
Deputy Chair- Information, IUCN SSC Invasive Species Specialist Group
University of Auckland (New Zealand)
School of Biological Sciences
Centre for Biosecurity and Biodiversity


Shyama PagadShyama Pagad, is an Honorary Academic based at School of Biological Sciences, University of Auckland, New Zealand. Shyama is tasked with establishing a sustainable platform for the development, management and enhancement of IUCN ISSG's knowledge products, including the Global Register of Introduced and Invasive Species (GRIIS) and the Global Invasive Species Database (GISD). She will work closely with the Global Biodiversity Information Facility (GBIF) and the Secretariat of the Convention on Biological Diversity to deliver GRIIS country checklists to national governments for their use in the management of invasive alien species. She will also lead the team that works on the development of biodiversity indicators related to alien and invasive species within the Biodiversity Indicator Partnership (BIP) of the UNEP-WCMC.

Riccardo has been working for several institutions and organisations based in Austria, Belgium, Bulgaria, Croatia, Denmark, France, Italy, Switzerland, The Netherlands, UK and New Zealand, among which the European Commission and some related bodies (the Executive Agency for Small and Medium-sized Enterprises, the Research Executive Agency, the European Environmental Agency, the Joint Research Centre), the Council of Europe, IUCN International, WWF-European Policy Programme.


Kahili ginger

Kahili ginger (Hedychium gardnerianum) is a showy ornamental which grows over a meter tall in wet climates, from sea level to an altitude of 1700 meters. It displaces native plants, forms vast, dense colonies and chokes understory vegetation. It can also block stream edges, altering water flow. It is dispersed by birds over short distances and by man over long distances (in garden waste or via the horticultural industry). Even small root fragments will re-sprout, making it a very difficult plant to control. Manual removal and using herbicides are some of the options used in the control of its spread.

Kahili ginger is one of the '100 of the World's Worst Invasive species'.     Please read the Kahili ginger (Hedychium gardnerianum) profile on the Global Invasive Species Database (GISD) for more information on the ecology of the species, its introduced range, impacts on biodiversity and ecosystems and ways to prevent and manage its spread.
