Estuary Research Biome Project
Organisms that live in estuaries have developed unique adaptations to help them survive. The mangrove tree, for example, have developed the ability to survive in brackish waters by using filters in their roots to remove salt from the water they take in. Blue crabs have also adapted to life in estuaries by releasing their offspring into ocean water to develop before returning to estuaries and either moving upstream as males or downstream as females.
Why They are Important
How Have Humans Impacted Them?
2. Another way humans have impacted estuaries is through large-scale conversion of estuaries with draining, filling, damming, or dredging. This results in the loss of estuarine habitats.
3. Pollution is another impact humans have had on estuary biomes. Historically, estuaries have been considered areas to discard wastes. Pollutants like chemicals, heavy metals, and pathogens have severely degraded the water quality of the estuary and harmed the delicate and commercially important fish and shellfish that live in estuarine areas.
