Urban and Rural Trees

We are no longer collecting new data about trees within our river catchments. You are very welcome to download and use any of the resources listed below. Any data collected can be added to the Treezilla website

Many thanks to everyone who came to one of our tree measuring events or who submitted data to our website.

 Trees and Drought

Natasha_TreeWhat will you gain?


School participation in the DRY Project provides an opportunity for students to assist scientists by gathering valuable data in their local area for our Tree Survey.

The tree monitoring activities can take place at any time and for each tree we need to know: the location of the trees, the date sampled, tree species, trunk circumference, height, crown spread and crown depth in 2017. We would also like to know additional information about the natural timing of life cycle events such as the flowering times of trees and how they change over the years. We are also interested in collecting information on temperature, relative humidity and rainfall in the environment where the tree measurements were taken. For some schools we are able to give out a series of ‘i buttons’ which monitor temperature and relative humidity close to the tree in order to measure the effect of these factors on tree growth.

Teachers can incorporate the monitoring activities in class or select elements to adapt to other programmes of work. Alternatively, students can be supported to carry out the survey activities at home with the assistance of parents/carers as homework. The monitoring activities can be used to achieve a range of learning objectives related to a variety of national curriculum subjects including Science, Geography, Mathematics and Information Computer Technologies (ICT):

  • Students learn about the importance of trees and identify a range of tree species in their local environment.
  • Collect measurements on tree heights, trunk circumference, crown spread and crown depth and learn about phenology.
  • Students will learn about the impacts of climate change and drought on trees.
  • Students engage in, and contribute data to, a national survey using methods employed by scientist.

Resources for teachers

Teachers can download our Tree Studies Handbook for guidance and other teaching resources detailed below:

School Visits

We can also visit your school to carry out a tree event to help get you started. Email Patty or Sarah on dry@uwe.ac.uk or ring 0117 32 87350 for further information/assistance.


This is an exciting opportunity to gain valuable experience on a large-scale scientific project, learn tree identification skills, tree ecology and more broadly about the impacts of drought and climate change on the environment. Volunteers will receive a certificate detailing the number of hours spent on the project and essential skills acquired, which are important for many ecological or conservation jobs. Volunteers can download our Tree Studies Handbook for guidance and our Survey Form
