Management Information Sheet

Ash dieback was identified in the county in 2012. In 2016 we began surveying roadside trees to help us establish its distribution and the health of the trees.

As part of our research we would like your help to find out how many ash trees we have at our schools and how healthy they are. Finding trees that are either showing symptoms of ill health or those that are showing signs of possible resistance are both very important to us to help identify how the disease is impacting the trees.

If you have trees in your school grounds it's important that you identify if you have any ash trees.

If your school is owned or managed by Norfolk County Council:

Between mid-June and mid-September we need you to carry out a simple survey of your ash trees, take photos of them now, file them and photograph from the same places next year to determine how the crown has changed. This is a good way to assess whether a trees health is in decline.

The best time to assess an ash trees health is mid-June to mid-September when they are in full leaf. Without their leaves, dieback can be more difficult to spot, especially in mature trees.

You will need to complete a short questionnaire and return it to ashdieback@norfolk.gov.uk.

To help you assess the dieback level we have produced a guide. The questionnaire and how to guides are available on the Norfolk Schools website.

If your school is not owned or managed by Norfolk County Council:

You will need to monitor any ash trees in your grounds. The guide on the school website will help you to assess dieback, you can also keep photographic records to monitor dieback.

If you have any questions or require further information please email ashdieback@norfolk.gov.uk.
