Accessibility statement for the Kew science sites. These websites are run by Royal Botanic Gardens, Kew.

Giant waterlily pads in a pond

This accessibility statement is for Kew's science sites. These websites are run by Royal Botanic Gardens, Kew. We want as many people as possible to be able to use the websites. For example, that means you should be able to:

  • change colours, contrast levels and fonts
  • zoom in up to 200% without the text spilling off the screen
  • navigate most of the website using just a keyboard
  • navigate most of the website using speech recognition software
  • listen to most of the website using a screen reader (including the most recent versions of JAWS, NVDA and VoiceOver)

We’ve also tried to make the text on our websites as simple as possible to understand. Sometimes we use scientific language to explain our work. When we do this, we try to offer an explanation in plain English, or link to content elsewhere on our websites that will provide more information.

    AbilityNet has advice on making your device easier to use if you have a disability.

    The following sites are covered by this statement:

    • Plants of the World Online
    • ColPlantA
    • ColFungi

    JD Hooker

    The following aspects of the site are not fully accessible:

    • Content that is visible on hover is not shown on keyboard focus (2.1.1 keyboard)
    • Some information is displayed on hover via the title attribute, which isn’t available for keyboard users (2.1.1 keyboard)
    • An obvious focus indicator was missing from many interactive elements (2.4.7 focus visible)
    • The focus order was not always predictable because positive tabindex values are used (2.4.3 Focus order)

    Disproportionate burden

    Where the impact of fully meeting the requirements is too much for an organisation to reasonably cope with, the organisation can argue that meeting the requirements is a ‘disproportionate burden to fix’. We believe that the following science data and digital resources meet this criteria.

    Archive catalogue

    The online archive catalogue contains collection and item level descriptions relating to the archive holdings of Kew. This includes manuscripts, bibliographic records, digital images of photographs and many other types of material held by us. We believe the current site is a disproportionate burden to fix as we are already in the process of rebuilding this site, which is due to go live in Summer 2022.

    Basidiomycete checklist

    This Basidiomycete checklist database provides information on all species of the fungal phylum Basidiomycota (including mushrooms and toadstools, bracket fungi, puffballs, earthstars and stinkhorns, club and coral fungi, tooth fungi, jelly fungi, rusts and smuts) recorded in the British Isles. We believe the current site is a disproportionate burden to fix as the site uses old web technology and has a small user base. We are in the process of developing a new website to provide access to fungal names and taxonomy – this will be released in October 2022.

    Economic Botany Database

    This is the online database for Kew’s Economic Botany Collection (EBC), which is one of the largest collections of specimens at the Royal Botanic Gardens, Kew. It contains about 90,000 plant raw materials and artefacts representing all aspects of craft and daily life worldwide, including medicines, textiles, basketry, dyes, gums and resins, foods and woods. We believe the current site is a disproportionate burden to fix as the data held within this database is being migrated into Kew’s new integrated collections data portal at which point this website will be decommissioned. The planned date to complete this is January 2023.

    Fungarium Catalogue (Herb IMI)

    This website allows users to search the Herb IMI database which contains around 400,000 records, mostly comprising specimens vouchered in the IMI fungarium (dried collection of fungi). We believe the current site is a disproportionate burden to fix as the data is being migrated into Kew’s new integrated collections data portal at which point this website will be decommissioned. The planned date to complete this is October 2022.

    Fungarium Catalogue (K)

    The Fungarium Catalogue (K) at the Royal Botanic Gardens, Kew contains data on the largest collection of dried fungi in the world. Together with the CABI collection [collection code IMI], it contains about 1.25 million specimens, including the British National Collections (ca. 300,000 specimens), approximately 50,000 types, and other specimens from over 240 countries on all seven continents. We believe the current site is a disproportionate burden to fix as the data is being migrated into Kew’s new integrated collections data portal at which point this website will be decommissioned. The planned date to complete this is October 2022.

    GeoCAT

    The Geospatial Conservation Assessment Tool can perform rapid geospatial analysis of species in a simple and powerful way. We believe the current site is a disproportionate burden to fix as the site uses old web technology and does not have sufficient users to justify redevelopment.  We plan to discontinue this website in May 2022 after incorporating the functionality it contains in other services.

    Grassbase

    The Grassbase website presents a set of detailed morphological descriptions of all grass species. We believe the current site is a disproportionate burden to fix as the site uses old web technology and does not have sufficient users to justify redevelopment.  We plan to discontinue this website in May 2022 after incorporating the information it contains in other services.

    Herbarium Catalogue

    The Herbarium Catalogue provides access to specimen records and images available in Kew’s Herbarium. We believe the current site is a disproportionate burden to fix as the data is being migrated into Kew’s new integrated collections data portal at which point this website will be decommissioned. The planned date to complete this is October 2022.

    Index Fungorum and Species Fungorum

    The Index Fungorum and Species Fungorum websites are the result of a project to index all scientific names in the fungus kingom. The sites use old web technology and have a niche audience. We believe the current site is a disproportionate burden to fix as we are in the process of developing a new platform to provide access to fungal names and taxonomy – this will be released in October 2022.

    Millennium Seed Bank Partnerships Data Warehouse

    The Millennium Seed Bank Partnerships Data Warehouse provides seed accession data, germination test data, georeferenced data, x-ray images and IUCN threat categories for seeds banked by the Millennium Seed Bank Partnership. We believe the current site is a disproportionate burden to fix as it is not possible to fix the current site without updating the database software used to manage the data. This upgrade will be completed by November 2023, by which time an updated site will be in place.

    Millennium Seed Bank Seed List

    The Millennium Seed Bank Seed List shows Millennium Seed Bank Partnership collections held at Kew's Millennium Seed Bank and at Partner Institutes. We believe the current site is a disproportionate burden to fix as a rebuild is nearly complete and is due to go live in June 2022.

    Seed Information Database

    The Seed Information Database is a compilation of seed biological trait data from the Millennium Seed Bank Partnership's own collections and from other published and unpublished sources. We believe the current site is a disproportionate burden to fix as this site is being retired in May 2022 when the information will be migrated to several of our other databases.

    World Checklist of Selected Plant Families and World Checklist of Vascular Plants

    The World Checklist of Selected Plant Families and the World Checklist of Vascular Plants are international collaborative programmes that provide the latest peer reviewed and published opinions on the accepted scientific names and synonyms of selected plant families and vascular plants. We believe the current sites are a disproportionate burden to fix as these sites are currently being phased out and will be retired by the end of 2022.

    UK Overseas Territories Online Herbarium

    The UK Overseas Territories Online Herbarium provides internet-based access to a virtual herbarium which, in the first instance, comprises digitized geo-referenced herbarium specimens from Kew's collection together with associated data, field images and key botanical literature. We believe the current site is a disproportionate burden to fix as it is not possible to fix the current site without updating the database software used to manage the collection. This upgrade will be completed by November 2023, by which time an updated site will be in place.

    Content that's not within the scope of the accessibility regulations

    State of the World's Plants and Fungi microsite

    We believe that the microsite created for the State of the World's Plants and Fungi reports (2016-2018) is exempt from the Public Sector Accessibility regulations as it is a legacy site and has not been updated since 2018.

    Technical information about this website’s accessibility

    Royal Botanic Gardens, Kew is committed to making its websites accessible, in accordance with the Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018.

    Preparation of this accessibility statement 

    This statement was prepared on 5th July 2022. This page was last reviewed on 8th July 2022.

    This websites covered in this statement were tested between October 2021 and June 2022. The tests were carried out by Nomensa.

    We took a sample of pages that represented the templates and types of content available on the website and tested a selection of journeys and tasks. We also ran an automated scan of the website to find areas that might have different issues.

    What we’re doing to improve accessibility

    Following audits across all Kew sites between October 2021 and July 2022, we have identified a number of areas where their accessibility can be improved. Some of these fixes have been made and we expect a significant number more to be made during the remainder over the next 6-12 months. We will regular review and update this statement as these changes are made.
