The University of Gdañsk Herbarium (UGDA) was established in 1970 on the initiative of Professor Hanna Piotrowska. Her collection documenting the flora of the Wolin Island and the Polish part of the Uznam Island numbering about 220 000 specimens including about 4500 from the Wolin collection is deposited in the herbarium to this day.​

Today the herbarium has accumulated resources, which due to their diversity are divided into several collections:​

• Herbarium of Vascular Plants (UGDA), which includes a large collection of vascular plants mainly from the area of Pomerania, with special emphasis on the area of the Slowinski and Wolin National Park.
• The herbarium of bryophytes (UGDA-B) containing about 12 000 specimens, mainly from the area of Northern Poland, with particular attention paid to the area of Gdañsk Pomerania
• herbarium of lichens (UGDA-L) including both domestic and foreign specimens, especially from South America; about 60 000 specimens.
• Prof. D. Szlachetko’s collection (UGDA-Orchid), created since the early 90’s and successively included in the herbarium resources, currently numbers about 10 000 specimens.
• Collection of samples of genetic material (UGDA-DNA) currently includes over 1,000 records deposited in the form of tissue and DNA extracts.
• The Orchidaceae wet preparation collection (UGDA-Liquid), numbering about 10,000 preparations, in which orchid flowers fixed in preservative liquids.
• Original engravings, whose collection of about 15,000 plant cards from around the world is a unique collection made during herbarium searches.

​As one of five Polish scientific institutions, the UGDA herbarium holds a CITES certificate (number in the register of CITES Scientific Institutions: PL003).​

The herbarium has been in existence since 1969 and represents a collection of approximately 68,000 herbarium sheets, including.

• Vascular plant collection – over 55,000 specimens.
• Collection of fungi (SLTC-F) – 2,950 specimens.
• Collection of lichens (SLTC-L) – 11,000 specimens.

The collection of vascular flora from Pomerania, with particular emphasis on the flora of Polish seaports (herbarium by E. Misiewicz).
In 1990 a collection of lichens was added (I. Izydorek herbarium). A part of the collection are materials dating from the mid-nineteenth and early twentieth century, the so-called Darłowo herbarium. The 1,500 sheets, dating from 1897-1943, are authored by German teachers, pastors and apothecaries, such as Ernst Holzfuss, Hermann Krause, Otto Karl, Alfred Bannier. Most of these collections come from Pomerania, but also from the Sudety Mountains, the area of Świdnica, Świeradów Zdrój and Wołów, as well as from Macedonia, Capri and Pompeii. Moreover, the herbarium of the Slovinski National Park in the number of 900 alegates stands out in the collection. It is a valuable historical document on vascular flora of this part of Pomerania. An integral part of the collection is also a herbarium of the former Botanical Garden in Slawno from the turn of the 19th and 20th century in the number of 78 cards of vascular plants.

The Herbarium’s botanical collection includes a number of plants that are both extinct and endangered on a national scale, as well as
Pomerania – the collections of Karl Friedrich Kohlhoff and Fritz Römer. Unfortunately, a part of Fritz Römer’s collection in the form of algates of the Rosaceae family was taken to the Botanical Garden Museum in Berlin Dahlem before the First World War. The same fate befell the collection of the Darlowo Museum, which was taken to Torun immediately after World War II and today forms part of the collection of the TRN – Nicolaus Copernicus University.

Herbarium Stetinense was established in 2013 on the initiative of Prof. Dr. Adam Zajac, Em. Prof. of the Jagiellonian University and Prof. Dr. Agnieszka Popiela of the University of Szczecin. The herbarium comprises the following collections: herbarium of vascular plants SZUB-VP, herbarium of lichens SZUB-L, herbarium of fungi SZUB-F and historical German collection (1837-1939). The Stetinense Herbarium currently holds about 60,000 vascular plant specimens, about 8,000 fungi, and 5,000 lichens.

Herbarium Stetinense is the first herbarium registered in Index Herbariorum in the history of Szczecin. It functions as the only synthetic source on the resources of West Pomerania with respect to vascular plants, fungi and lichens. It is an important evidence of the current and historical composition of the flora and mycobiota, a source of information on the biodiversity of Western Pomerania, a source of material for taxonomic, morphological, anatomical, ecological, etc. studies, a source of DNA for molecular systematics, and a source that plays an important role in assessing the degree of threat when developing biodiversity conservation programmes.

Particularly valuable are the historical collections of German scholars (e.g. German collections from the 19th century, Baenitz herbarium) and of Polish scholars who studied Pomerania after 1945: the collections of professors: Kownas, Jasnowska, Ćwikliński, Ciaciura) as well as taxonomically important and nationally unique developed scientific collections (Carex group flava, Elatinaceae, Opegrapha s.l., Rubus). Moreover, the collection includes vascular species and macroscopic fungi of Pomeranian fens, xerothermic lichens of Pomerania, lichens of the Bukowa Forest, Drawa and Wolin National Park, Goleniowska Forest and Wkrzanska Forest. Many of them are reference specimens quoted in publications. About 80% of the collection comprises specimens from Western Pomerania, the remaining ones come from other regions of Poland as well as Scandinavia (Bornholm, Norway), the Mediterranean basin (Balearics, Sardinia, Apennines, Peloponnese), Armenia and Russia (lichens). We also have specimens from exchange (mainly from South-East Asia).

The Szczecin Diatomological Collection is part of the Diatomological Unit of the Institute of Marine and Environmental Sciences, University of Szczecin. It was founded in 1996 by Professor Andrzej Witkowski.

The Collection contains samples and microscopic preparations of diatoms from all continents and from many unique environments, such as the Galapagos Archipelago and Madagascar. The Collection contains type specimens from which many diatom species new to science have been described, but also a number of samples still awaiting identification that contain numerous species potentially new to science. The total number of archived diatom preparations is about 48,000. The Collection also includes the Szczecin Diatom Breeding Facility (known as the Szczecin Collection of Marine Diatoms), which aims to collect live specimens, mainly of saltwater species. Currently, about 2000 strains are kept in the culture. Vast majority of isolated strains are benthic species from the littoral zone of various localities, in particular the coasts of the Atlantic and Indian Oceans and their marginal seas, and the western Pacific.
