Root and branch research with big Black Country tree survey
THE Big Black Country i-tree Eco project is now in progress, and surveyors are out in the area, measuring trees across the Black Country with sample plots being surveyed in Dudley, Wolverhampton, Sandwell and Walsall.
There are 1000 of them in total, each measuring 11.3 metres in radius. Plot areas are assessed and broken down into land use categories: tree, shrub, and other land cover. Also noted are the types of trees present, and the sizes of the trees. Plots are located in a variety of urban locations: parks, woodlands, as well as public and private land.
Consortium
This study is being led by the Black Country Consortium, in partnership with Birmingham Tree People, Treeconomics, Barton Hyett Associates, and Forest Research. The project is being funded by The Woodland Trust.
Those carrying out the data collection include not only experienced surveyors but also volunteers from across the area.
These volunteers are mostly tree wardens, but also some students from local universities and the Birmingham Institute of Forest Research (BIFOR). All volunteers have been trained in how to assess plots, and have been given equipment with which to do so. They are encouraged to use an app called Plantsnap, to help them identify the trees they find, and apps to help with measuring tree height. Volunteers are encouraged to identify the trees and shrubs they find, or to seek help if they are unsure.
Paul Barton, of Barton Hyett Associates, said: “Our teams of surveyors are making good progress with the survey and are generally well received by the local community, where they need to access plots on private land. We always find that explaining to landowners what we are doing is in itself worthwhile, as it gives us an opportunity to explain a little about how the urban forest provides so many benefits.
This study will be a really interesting one given the Black Country’s industrial heritage and we hope will lead to positive action to ensure trees in the area are valued by all.”
Over 500 plots have now been surveyed, and it is estimated that surveying will continue until the end of October. Once the fieldwork is complete, the data will be analysed using ‘i-tree Eco’, a software package used around the world to assess the environmental benefits of urban trees and their value to society. The final report will reveal exactly what the Black Country’s trees are contributing to the environment, and to the people who live and work there.
