Kick Sampling 2019 Season

Peter Welsh and Paul Leng undertook 3 kick sampling sessions during the 2019 season.  This provided us with indicative summaries of river life in our beat of the River Nidd


Sampling the river bed just below the bridge



A standard size net is used for all sampling procedures.  Here Peter is examining the contents following a 1 minute of sampling activity.  Initially the contents are washed within the net prior to being transferred to the holding bucket.



Once in position the net is placed onto the river bed and then a 'shuffling' or 'kicking' of the river bed is undertaken whilst slowly moving up stream during the minute the sampling is taking place.
This ensures a larger section of river is covered and hopefully this produces a variety of specimens to be examined.
The procedure is then repeated in different locations, subsequent sampling later in the year will try and ensure the same locations are used to enable comparisons to be made over the year and from year to year as we build up a data base of information.


Once the 3 One Minute samples have been gathered then the more difficult task of sorting and identifying each specie is undertaken.  The use of a standard size net is to ensure that there is comparability between each separate sample on the day as well as throughout all samples taken during the year.



Having sorted the sample into broad categories Peter and Paul then spend time examining each invertebrate to correctly categorise it prior to recording the results.  These can been seen below for the three samples taken during 2019
