Amphibians are a good indication beause their skin is very absorbant to chemicals and other nasties... look at it this way. U can kill a frog by touching his skin if u don't wet ur hand with his original water first. So they are very delicate creatures and if their living area becomes contaminated you can see a massive different in species and numbers. So to calculate say if a factory went up next so some wetlads or a marsh, people can take records from before it was built and compare the data to months after it was built to see if its polluting the area.

This means that if the air, water, or food source in a frog's environment is poluted, the frogs will have symptoms, including prone to diseases and abnormalties in offspring that let peole know that something is wrong.

∙ 15y agoThere is quite a large agreement that the frogs are good indicators of habitat disturbance, both locally and globally. The frogs skin is permiable in that it readily absorbs chemical substances, they have a fast generation time, they have low mobility at a landscape level in that if conditions are bad it is difficult for them to move on to a new habitat. They are also sensitive to changes in moisture, food abundances etc at the local area as they do not forage over a large area.
