The survey will help discover the wildlife in school playing fields
The wildlife that lives around Bristol's schools is to be recorded for the first time.
The project, which has been set up by the Avon Wildlife Trust, will see children across the city taking part.
The results from the Big Bristol Habitat Hunt will then be used to help develop plans for conservation.
Julie Doherty from Avon Wildlife Trust said school fields are "really important not just for learning but for the bio-diversity in Bristol."
She added that school playing fields are often home to all sorts of creatures and plants.
"In our increasingly urban environment sometimes the school grounds are little pockets of wildlife," she added.
"We want to do this strategic analysis to investigate and understand exactly how these fit in to the wider picture.
"We can put some things in to help maintain these and help manage them for the future."
