Tree Alert Page Topper

This accessibility statement applies to all domains.

Our websites are run by Forest Research. We want as many people as possible to be able to use this website and other sites in our portfolio.

To ensure this happens, the main website has been built using government guidelines and specific standards. That means that all core information is easily accessible by:

  • people with older systems or browsers
  • people with a slow internet connection
  • people with various abilities

The standards used mean that:

  • Most of all core information is text based (with the exception of maps, and images showing leaves, insects etc.)
  • the information is in web standard formats (e.g. html and pdf)
  • all file sizes are as small as possible
  • pages are structured
  • all text should be easily read
  • the navigation is clear and easy to use
  • any plug-ins required are available for free
  • the site will still be useable with images turned off
  • the site should look the same on different systems and browsers

We’ve also made the website text as simple as possible to understand.

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

Barriers to accessibility

Although we are striving to reach AA level of accessibility which should ensure that most people with most technologies will be able to access our website and information, some areas will not meet the required criteria. Mostly they are legacy areas and websites and documents, such as our older PDF documents. Some areas rely on particular technologies such as mapping. In those areas we are aiming at providing the user with alternative ways to obtain the information if they cannot access it via the website.

Some websites such as Right Trees For a Changing Climate and Forest Research Decision Support Tools Portal v2.0 ( are legacy online databases and we are working on a plan to make their content and information fully accessible.

Accessibility of Tree Alert is part of an ongoing programme of development which we are improving all the time. The nature of TreeAlert means that users are occasionally asked to compare what they can see, such as visible signs of leaf disease or a type of insect inhabiting the tree, with photos of typical occurrences to assist in the identification of a disease. The nature of this functionality is difficult to achieve effectively under accessibility guidelines, and the likely users which this may affect (such as those with colour blindness).

Reporting accessibility problems with this website

We’re always looking to improve the accessibility our websites. If you find any problems not listed on this page or think we’re not meeting accessibility requirements, please contact us, or get in touch with our Communications team.

Enforcement procedure

The Equality and Human Rights Commission (EHRC) is responsible for enforcing the Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018 (the ‘accessibility regulations’). If you’re not happy with how we respond to your complaint, contact the Equality Advisory and Support Service (EASS).

Technical information about this website’s accessibility

Forest Research is committed to making its website accessible, in accordance with the Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018.


Our websites are partially compliant with the Web Content Accessibility Guidelines version 2.1 AA standard, due the non-compliances and exemptions listed above.

Non-compliance with the accessibility regulations

Some images and maps do not have a text alternative, so people using a screen reader cannot access the information. This fails WCAG 2.1 success criterion 1.1.1 (non-text content).

The heading structure is incorrect on a small number of pages, with the “heading 5” level not containing text. This fails WCAG 2.1 success criterion 1.3.1 (Info and Relationships).

Some form data entry fields do not contain information for what the field is for, so a screen reader cannot relay this information. This fails WCAG 2.1 success criterion 3.3.2 (Input Assistance).

When we publish new content, we will make sure our use of images meets accessibility standards and we will review current ones as we come across them. 

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

Some older content is not covered by accessibility regulations and is listed here. These are not applicable to TreeAlert, but do occur in other parts of our website.

PDFs and other documents

Some of our PDFs and Word documents are essential to providing our services. For example, we have PDFs with information on how users can access our services, and forms published as Word documents. We hope to have all top accessed information either in HTML pages or accessible word documents by early 2022.

The accessibility regulations do not require us to fix PDFs or other documents published before 23 September 2018 if they’re not essential to providing our services. For example, we do not plan to fix archive pdfs.

Any new PDFs or Word documents we publish will meet accessibility standards.

Live video

We do not plan to add captions to live video streams because live video is exempt from meeting the accessibility regulations, however we strive to have subtitles for most of our videos from Aug 2021.

How we tested this website

We use the Web Content Accessibility Guidelines V2.1 level A and level AA to test how accessible the Forest Research website is. We selected the sample of pages to test based on the popularity of the page, the importance of the information on the page and the visibility of the page.

This website is under active development and is being tested on an ongoing basis using the following:

  • Google Lighthouse
  • WAVE
  • SiteImprove
  • Manual inspection

We tested our main website, available at and TreeAlert at

What we’re doing to improve accessibility

Forest Research is undertaking a programme of development on its website and related tools and service to comply with accessibility regulations and a give better user experience. We expect the work to be completed during 2022.
