The Asian water monitor is semiaquatic and opportunistic; it inhabits a variety of natural habitats though predominantly resides in primary forests and mangrove swamps. It has been noted that it is not deterred from living in areas near human civilization. In fact, it has been known to adapt and thrive in agricultural areas as well as cities with canal systems, such as in Sri Lanka, where they are not hunted or persecuted. Habitats that are considered to be most important are mangrove vegetation, swamps, wetlands, and elevations below 1,000 m (3,300 ft). It does not thrive in habitats with extensive loss of natural vegetation and aquatic resources.
Quahog Bay Conservancy Staff collect water samples weekly at seven established monitoring stations throughout the Bay, which are screened for total coliforms (sewage contamination). Samples are tracked and analyzed for patterns based on location, tides run-off, or other adverse conditions. Data from monitoring will be used to identify 'hot spot' problem areas. The sample pictured here was collected and tested on August 10, 2016.
