Obyan Beach Reef Flat- Benthic & Macroinvertebrate Results

The Obyan Beach reef flat is located in the South Coast of Saipan, CNMI. Several beaches made up of coarse sand and gravel give the reef flat a total area of about 3,300 feet with a vairable width of up to 150 feet. The strong currents at Obyan can make swimming quite dangerous a times.

The main access road is crushed coral gravel and subject to serious erosion during rainy seasons.  CRM and DEQ are actively seeking to mitigate the effects of this pollution source.  Parking lot relocation and paving as well as revegetation where the main road led to the beach appears to be having a positive effect in reducing near shore turbidity and increasing coral cover.
