Global Plants Initiative (GPI):
The Herbarium Hamburgense is a partner institution in the Global Plants Initiative (GPI) and its precursor programs African and Latin American Plants Initiative (API, LAPI). Supported by the A.W. Mellon Foundation the types as well as historically important specimens of seed plants (phanerogams) are digitized and scanned. The datasets and high-resolution scans are presented online via the portals JSTOR Plant Science, GBIF as well the Herbarium Hamburgense homepage. The project has been started in 2006 and scheduled to last until 2015. Scans of some 20,000 type specimens are expected to be made available to the public.
Global Biodiversity Information Facility (GBIF):
From 2004 to 2006 four projects have been conducted with support from GBIF-Germany to digitize and scan parts of the HBG collections, viz. the collections of Aizoaceae, the orchid and bryophyte type specimens as well as the cultivated algae.
The collection of dried and living Aizoaceae in Hamburg is one of the largest of its kind in the world. It has been assembled predominantly during the past 40 years. Further collections are those of DINTER and SCHWANTES dating from the 1920ies as well as collections from the 19th century (ECKLON & ZEYHER, DR╚GE, SCHLECHTER).
After the reincorporation of herbarium material that had been evacuated and inaccessible from 1943 to 1992 and the rediscovery of the private orchid herbarium of F. KR─NZLIN, the Hamburg orchid collection has been studied by various specialists such as E.A. CHRISTENSON, D.L. SZLACHETKO and G.A. Romero. According to a recent inventory the HBG orchid herbarium contains ca. 1,000 type sheets. More than 2,000 sheets of types and other important specimens have been digitized.
Besides the orchids, the bryophyte collection has been traced for valuable type material, databased, photographed and made available online. Approximately 2,000 types and typoid specimens have been captured.

Checklists of Lichens and Lichenicolous Fungi
Checklists of lichens and lichenicolous fungi from 618 geographical units have been compiled with support from the German Science Foundation (DFG) and are searchable online.
