Biological monitoring is the study of organisms found in our waterways. The type and abundance of these organisms can be used as indicators of water quality because all organisms require specific conditions to live.
The Important Of Biological Monitoring
It is a relatively inexpensive and reliable method of acquiring an indication of the water quality and uses simple and inexpensive tools. By identifying 'sensitive' aquatic insects, we can use them as 'bio-indicators' of different levels of water quality. These organisms can provide a relative view of the overall quality of a stream at any given moment.
Biological Monitoring Method
Make sure you have a container filled with water to place your organisms in before you begin. If you find anything, gently pick it up using forceps or your fingers, or use some water to wash it into the container. Once you have finished, please remember to return the animals back into the water carefully!
