The UK holds some of the world’s most important natural science collections. More than 130 million specimens have been collected from around the world and are held in over 90 institutions throughout the country.Continue reading “Releasing the power of UK collections | Digital Collections”
A Decade of Digitisation | Digital Collections
A guest blog by Pete Wing
January 2023 marks the tenth anniversary since I first started digitising the Museum’s collections. A lot has changed in that time but the main principle of digitisation has remained the same: to transform the access and use of the Museum’s collections through unlocking natural history data and sharing this with the world.Continue reading “A Decade of Digitisation | Digital Collections”
Digitising beans to feed the world
Legumes are a group of plants that include soybeans, peas, chickpeas, peanuts and lentils. They are a significant source of protein, fiber, carbohydrates, and minerals in our diet and some, like the cow pea, are drought resistant.
A new paper has been published in Biodiversity Journal about a project that the digitisation team started in 2018 with the Royal Botanic Gardens Kew (project Lead) and the Royal Botanic Garden Edinburgh, to collectively digitise non-type herbarium material from the legume family This includes rosewood trees (Dalbergia), padauk trees (Pterocarpus) and the Phaseolinae subtribe that contains many of the beans cultivated for human and animal food.
This project was made possible through Department for Environment Food & Rural Affairs (DEFRA)-allocated Official Development Assistance (ODA) funding, distributed by the UK government in its “global efforts to defeat poverty, tackle instability and create prosperity in developing countries”.

The legume groups Dalbergia, Pterocarpus and Phaseolinae were chosen for digitisation to support the development of dry beans as a sustainable and resilient crop, and to aid conservation and sustainable use of rosewood and padauk trees. Some of these beans, especially cow pea and pigeon pea, are sustainable and resilient crops, as they can be grown in poor-quality soils and are drought stress resistant (Varshney et al. 2009). This makes them particularly suitable for agricultural production where the growing of other crops would be difficult.
Digitally discoverable herbarium specimens can provide important information about the distribution of individual species, as well as highlighting which species occur naturally together. While there have been collaborative efforts between herbaria in the past, these have tended to prioritise digitisation of type specimens – as the example specimens for which a species is named, types are important to identification, but as individual specimens don’t offer insights into species distribution over time. By focusing on the non-types across the world and over the last 200 years, we have released a brand-new resource to the global scientific community.
Searching for beans
This collection was digitised by creating an inventory record for each specimen, attaching images of each herbarium sheet, and then transcribing more data and georeferencing the specimens, providing an accurate locality in space and time for their collection.
We originally had four months and three members of staff to digitise over 11,000 specimens. The Covid-19 lockdown was ironically rather lucky for this project as it enabled us to have more time to transcribe and georeference all of the records.
We were able to assign country-level data to 10,857 out of the total number of 11,222 records. We were also able to transcribe the collectors’ names from the majority of our specimen labels (10,879 out of 11,222). Only 770 out of the 2,226 individuals identified during this project collected their specimens in ODA listed countries. The highest contributors were: Richard Beddome (130 specimens), Charles Clarke (110), Hans Schlieben (98) and Nathaniel Wallich (79). The breakdown of records by ODA country can be seen in the chart below.
From our data, we can see the peak decade of collection was the 1930s, with almost half (4,583 specimens or 49,43%) collected between 1900 and 1950 (Fig. 10). This peak can be attributed to three of our most prolific collectors: Arthur Kerr, John Gossweiler and Georges Le Testu, all of whom were most active in the 1930s. The oldest specimen (BM013713473) was collected by Mark Catesby (1683-1749) in the Bahamas in 1726.
An interesting, but perhaps unsurprising, finding is that our collection is strongly male dominated. There are only two women (Caroline Whitefoord and Ynes Mexia) in the list of our top 50 plant collectors and they are not close to the most prolific collectors. We identified more women in the rest of our records, but their contribution is on average less than 25 specimens per person in the dataset consisting of more than 10,000 specimens. In contrast, the top five male collectors contributed 10% of our collection.
Both the Pterocarpus and Dalbergia genera include species that are used as expensive good quality timber that is prone to illegal logging. Many species such as Pterocarpus tinctorius are also listed on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. By releasing this new resource of information on all these plants from three of the biggest herbaria in the world is that we can share this date with the people who are taking care of biodiversity in these countries. The data can be used to could be used to identify hotspots, where the tree is naturally growing and protect these areas. These data would also allow much closer attention to be paid to areas that could be targets for illegal logging activity.
Pterocarpus tinctorius is a species of padauk tree that is listed as endangered on the IUCN Red List. Cowpea (Vigna unguiculata) is a food and animal feed crop grown in the semi-arid tropics.
The ODA-listed countries are economically impoverished and disproportionally prone to be disadvantaged with the changing climate whether from flood or drought or increase in temperature. Using data to identify good, nutritious plant species that can be grown in such conditions can therefore benefit local communities, potentially reducing dependence on imports, aid and on less resilient crops.
This dataset is now openly available on the Museum’s Data Portal and a paper about this work has been released in Biodiversity Journal. Stay in touch with the Digitisation team by following us on Instagram and Twitter.
