Stream Survey - Natural History
Location: Dorset
Stream Survey 1 at Broadwindsor County Primary School
- report by Serena Bower, People and Wildlife Officer, Dorset Wildlife Trust, working with a class of 7 to 9 year-old children
“At 9.00am on Wednesday 24th September the class was split into two one hour sessions. This was for health and safety reasons; each half doing a one hour session on the stream.
When studying the stream, the group was split into two – one group doing the stream dipping and water quality, the other group making a start on the physical site descriptions.
The stream dipping went well, with some good water quality indicator species being found. On the whole, using a simple technique, the water quality was found to be of excellent quality. This took up most of the half hour so there was not time to do the solutions and pollutions section on the worksheet.
The physical studies of the river looked at things such as water temperature, depth, width and speed. It also looked at the bank side for things such as rubbish and tree species. There was not time to do the bank side vegetation quadrats or the mapping.
The idea of the exercise was to get the pupils to know the character of the stream and how it changes throughout the year. It is also a chance for them to monitor the changes, such as basic water quality and vegetation changes. The latter is particularly prominent at the moment as the bank has had some trees and nettles removed, allowing more light and space for other plants to grow.
Future work - There is plenty of follow up in-class work that could be done from these studies. This ranges from producing a largescale map and photographic records, to comparisons with other streams and the production of graphs showing the change through the years.
It was felt that once every term was sufficient to produce a good record of the stream. The next date is set for Thursday March 11th. The format will be very similar, although the worksheet will be altered to allow the vegetation to be studied in the time allowed.”
