Dr. Piero Genovesi
Senior Conservation Officer
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 a senior conservation officer with the ISPRA (Institute for Environmental Research and Protection, created by the Italian Government after the suppression of INFS), where he coordinates the activities on alien species management.

Riccardo Scalera
Programme Officer, IUCN SSC ISSG


Piero GenovesiRiccardo Scalera is a naturalist with over 13 years experience in conservation biology, wildlife management and vertebrate ecology. He has a broad expertise on several nature conservation issues, such as biological invasions, international wildlife trade, herpetofauna conservation, vertebrate ecology and on EU nature conservation policies and related financial programmes (i.e. LIFE+).

He has been working as independent consultant for a number of public institutions and private companies in Italy, Belgium and Denmark, including the European Commission and the European Environment Agency. In Italy, other clients include the Ministry of Environment, the Ministry of Agriculture-National Forestry Corps, and the University of Rome.

In the past few years he has been collaborating extensively with the ISPRA (Institute for Environmental Research and Protection) (Italy) on several invasive alien species related projects, i.e. on DAISIE (Delivering Alien Invasive Species In Europe), a major initiative funded by the European Commission aimed at filling in the main knowledge gaps on the issue, on a document for the Council of Europe aimed at the development of a black list, and on a study funded by the European Environment Agency for the development of an early warning and information system.

Piero GenovesiShyama joined the ISSG in 2003 as Species Information Officer working mainly on the Global Invasive Species Database (GISD) supervising the compilation of species profiles and their peer review process.

Since 2009 she has been managing species information services for the ISSG; and the ISSG Regional Pacific Office, based at the University of Auckland in New Zealand. The Regional office serves as the Invasive Species focal point for IUCN Oceania Suva, Fiji.

Her work involves management and the development of invasive species related information resources, working on collaborative projects with global conservation groups. Shyama is the moderator of the ISSG's list service Aliens-L. She also operates an active referral service for global invasive species stakeholders.

Her research interest is in the area of assessing the impact of biological invasions on threatened species and vulnerable habitats.

Shyama's background is in Horticultural Sciences and Geographical Information Systems.

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.
