The School of Sciences of the University of Navarra has organized, together with the Public University of Navarra and the high school Pirenaico de Ecología-CSIC of Jaca, the XIX Herborization Campaign of the association de Herbarios Ibero-Macaronesicos (AHIM), which has taken place in the western Pyrenees and Pre-Pyrenees (Aragón-Navarra).

More than 60 institutional or individual members are members of this organization and maintain scientific collections of pressed, dried and labeled plant species as samples for study and as evidence of the presence of a species in a specific place and at a specific date.

In this context, 33 botanists representing fourteen herbaria, mainly from universities and research centers in Spain and Portugal, have traveled for four days to different localities of the Pre-Pyrenees (Canal de Berdún, Foz de Sigüés, Sierra de Leire, Sierras de Loarre, Monrepós, Cinco Villas) and Pyrenees (Valle de Tena, Formigal, Portalet, Balneario de Panticosa, Búbal, Biescas: Formigal, Portalet, Balneario de Panticosa, Búbal, Biescas), and have collected material for incorporation into the participating herbaria, as well as for programs of study specific to some of the scientists: yarrow(Achillea millefolium) for genetic and phytochemical research, ivy(Hedera sp. pl.) for programs of study biogeographical research, various Gramineae (Festuca, Trisetum...) for the project Flora Iberica, etc.

The activity has been completed with the visit to the organic cultivation of aromatic and medicinal plants of the business Josenea in the "Finca Bordablanca" of Lumbier (Navarra).

The list of herborized flora species and their localities can be consulted at bulletin of the AHIM and through the herbaria participating in the database of the Global Biodiversity Information Facility (GBIF), the main global initiative that allows free and open access to nearly 400 million records of biodiversity data .
