Digitisation project within the vascular plant collections

Within the scope of the 2015-2020 strategy, the ETH Library supports the digitisation and publication of 100'000 vascular plant specimens from the United Herbaria Z+ZT based on the latest standards and optimised workflows. The project is divided into three subprojects:

1. Release of a hitherto inaccessible collection: The approximately 6'000 specimens assembled by Hans Hess from Angola will be mounted, labelled and digitised, before being made publicly accessible through our web portal, along with relevant metadata.
2. Establishment of international imaging standards: Thanks to two digitisation stations and state-of-the-art imaging equipment, all 15'000 type specimens housed at the United Herbaria Z+ZT are going to be photographed and made freely accessible through our webpage.
3. Annual management and release of 100'000 herbarium records: The establishment of an efficient digitisation workflow will enable us to re-organise and catalogue all estimated 85'000 records of the family Brassicaceae from our collections. With the help of (citizen) scientists, taxonomic revisions and relevant metadata will be incorporated, to promote the use of these specimens in future research projects.

Botanical curiosities discovered throughout our digitisation efforts are being regularly presented by Dr. Guilhem Mansion (in English or French).

Digital recording of the bryophyte collection Hans Hürlimann

The private bryophyte collection of Hans Hürlimann comprises around 4,800 specimens and was handed over to the herbaria Z+ZT in 2008. Besides specimens from Switzerland, it includes samples from numerous European countries and almost all other continents. The specimens were collected between 1937 and 2003. With financial support of the Foundation for the Promotion of Plant Knowledge, the specimens are now photographed and recorded digitally. The already processed specimens can be viewed publicly in the the online collection of the herbaria Z+ZT. The project will be completed by the end of 2018.

Botanical tourism in Saastal

The herbarium Keller-Naegeli (HKN), originally one of the largest private plant collections in Switzerland, is part of the United Herbaria Z+ZT. HKN amongst other focused their attention on the valleys around Visp in Valais. The project on botanical tourism in Saastal is an important step in the processing of this herbarium. Together with the written and photographic documents obtained, the historical plants provide a valuable insight into the cultural history of botanical collection.

Moosflora of Switzerland

The project "Moosflora der Schweiz" aims at providing electronic access to photographs and data on the morphology, ecology and distribution of all 1'100 mosses occurring in Switzerland. The United Herbaria Z+ZT have extensive bryological collections that are made available for the study of morphological features and the preparation of pictures for this project. The historical data further provide important information on the earlier distribution of the species.

Flora of the Canton of Zurich

The project "Flora des Kantons Zürich" is intended to systematically record the plants diversity in this Canton. The project does not only focus on the actual biodiversity, but also on historical plant distribution. The United Herbaria Z+ZT constitute an important source of historical data. We therefore support the project "FloZ" by actively participating in the collection of historical findings from the Canton of Zurich.
