About ColPlantA and POWO

In 2015, the Royal Botanic Gardens, Kew launched its first Science Strategy establishing its vision to document and understand global plant and fungal diversity and their uses, bringing authoritative expertise to bear on the critical challenges facing humanity today. The Science Strategy also committed Kew to delivering nine strategic outputs with the overarching aim to disseminate Kew's scientific knowledge of plants and fungi to maximize its impact in science, education, conservation policy and management. The Plants of the World Online portal (POWO), is one of the nine strategic outputs and its aim is to enable users to access information on all the world's known seed-bearing plants by 2020.

With over 8.5 million items, Kew houses the largest and most diverse botanical and mycological collections in the world in the Victorian Herbarium and Fungarium in West London. They represent over 95% of known flowering plant genera and more than 60% of known fungal genera and yet, only 20% of this knowledge is available online. POWO is Kew's way of turning 250 years of botanical knowledge into an open and accessible online global resource.

POWO draws together Kew's extensive data resources including its regional Floras and monographs, alongside images from the digitisation of the collections. The portal has been designed to maximise accessibility and enables the dissemination of plant information to its users via a mobile, tablet or desktop computer.

POWO was launched in March 2017 with a focus on key tropical African Floras - Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa specifically. Descriptive data from these Floras was linked via a curated taxonomy to images from the digitisation of the collections enabling Kew to finally put a substantial part of these Floras online. In addition, data from Kew's Grassbase and PalmWeb databases have also been included along with species level data for some but not all Orchids.

It is important to note that POWO is not perfect and represents work in progress - see Limitations below. Ultimately, POWO will become a single point of access for authoritative plant species information, a multi-dimensional catalogue of plant life, including information on identification, distribution, traits, conservation, molecular phylogenies and uses. The codebase is open source and Kew hopes to support existing partner networks to set up their own portals, creating a distributed network of botanical data hubs. POWO aims to become a resource that has global coverage which can empower and inform citizens, policy makers, conservationists and farmers everywhere, about the importance of plants and fungi to life.

Limitations of POWO

POWO is not perfect and represents work in progress. Data comes from a variety of sources which are both monographic (global) and regional in scope. These data sources vary in the extent to which comprehensive synonymy is included, their stage of development (proximity to publication) and the degree to which they have been exposed to peer review.

There exist other reliable authoritative sources of taxonomic opinion for some groups or some regions which we simply have not had time yet to include. Our ambition is for future versions to be more inclusive and comprehensive. POWO is a dynamic resource and content is added continuously. By 2020, POWO will be the most comprehensive single information resource covering all plants but it will be imperfect and not all the taxonomic decisions contained derive from a peer reviewed, curated, authoritative source. POWO therefore should only be treated as advisory. Other, more authoritative lists may exist for particular regions or taxa.

POWO is only possible through the generous support of our benefactors, Michel and Hélène David-Weill.

What ColPlantA is

  • ColPlantA is a landing page with pre-filtered species profiles, hosted in the Plant of the World Online Portal (PoWO;, with specific features (i.e. links to items in Kew/RBGE collections, additional information on global/Colombian geographic distribution, etc.).
  • ColPlantA will aggregate extant information in other portals (such as SiB Colombia and Catálogo de Plantas y Líquenes de Colombia), and will link to them. Therefore, it will be a window of visibility for these Colombian portals, amplifying the impact that they already have.
  • ColPlantA will live in the platform POWO, and therefore will have a strong management support as a long-term, sustainable resource.
  • ColPlantA will be an authoritative, expert-driven, constantly updated resource.
  • Because of the limited budget, most of the information to be hosted in ColPlantA will come from aggregation of data already available in other portals and in Kew's databases.
  • ColPlantA will hold only open-access information. Kew's policies state that all data have to be freely accessible (CC BY license). Therefore, information in ColPlantA may contribute to SiB Colombia (both in number of registers and contents). Prioritisation of species profiles can be decided in agreement with SiB Colombia and Colombian partners.
  • As part of PoWO, ColPlantA will be based on structured content, following pre-defined standards (e.g. Darwin Core archive (DwCA), Economic Botany Standards). This will facilitate sharing and exchanging information with Colombian partners (e.g. SiB Colombia, Catálogo de Plantas y Líquenes de Colombia)
  • Kew is always looking for collaborative efforts, and this is not the exception. By creating ColPlantA, Kew expect to be able to establish a two-way collaboration with Humboldt and the SiB Colombia Team.

What ColPlantA is not

  • ColPlantA will not compete with any other portals. It aggregates information from different sources, providing the link and reference for the sources. Therefore, ColPlantA is not another SiB Colombia or another Catálogo de Plantas y Líquenes de Colombia.
  • ColPlantA will not be another parallel platform, since there is no any platform aiming to aggregate information from other Colombian and global sources.
  • ColPlantA will not be built from zero (not a build-from-the-ground portal). It will be hosted in the PoWO, and therefore will use the same global taxonomic backbone and infrastructure for data.

Advantages of ColPlantA

While SiB Colombia is focused on local, Colombian information and scale, ColPlantA will build species profiles taking into account verifiable content from national, regional and global sources. In addition, by keeping the references and links to the source data, ColPlantA will increase visibility of partners collaborating with the project (e.g. SiB Colombia). For instance, the profile for Vachellia nilotica, shows in the description sections from Flora Zambeziaca and Flora of Tropical East Africa, in addition to Kew's information. Then information already available from SiB Colombia profiles could be displayed (of course with the previous consent from the SiB Colombia Team) in ColPlantA.

ColPlantA is possible thanks to

The Royal Botanic Gardens, Kew (Kew) is an executive non-departmental public body part-funded by the United Kingdom Department for Environment, Food and Rural Affairs. Kew is a global resource for plant and fungal knowledge, whose scientific vision is to document and understand global plant and fungal diversity and its uses, bringing authoritative expertise to bear on the critical challenges facing humanity today.

This work was delivered by the Royal Botanic Gardens, Kew supported by a Newton-Caldas Fund grant. The grant was awarded by the UK Department for Business, Energy and Industrial Strategy under the Colombia Bio partnership between the British Council and Colciencias.
