KINGSTON, R.I. \u2013 July 17, 2017 \u2013 Michael Bradley calls eelgrass \u201cthe canary in the coal mine for estuarine health.\u201d The flowering plant that grows beneath the surface of coastal waters and salt ponds provides nursery habitat for shellfish and finfish while also dampening wave energy, stabilizing sediments and serving as an indicator of clean water.<\/p>\n
But according to a recently issued report by the 溏心vlog免费B站\u2019s Environmental Data Center, eelgrass in Rhode Island is declining in Narragansett Bay and in most of the state\u2019s coastal salt ponds.<\/p>\n
The report found 1,144 acres of eelgrass and other submerged vegetation in state waters, an 18 percent decrease from 2012. The largest declines occurred in Quonochontaug Pond (52 percent), Point Judith Pond (48 percent) and Little Narragansett Bay (25 percent).<\/p>\n
More than half of the state\u2019s eelgrass occurs around Jamestown, which experienced a 19 percent decrease in eelgrass acreage. Ninigret Pond was the only coastal pond not to have a decrease, and the Narrow River was the only site that experienced a significant increase (45 percent) since 2012.<\/p>\n
\u201cIt\u2019s difficult to know exactly what\u2019s going on,\u201d said Bradley, a 溏心vlog免费B站 research associate and lead author of the report. \u201cThe reasons can be varied. An increase in water temperature could have something to do with it. Pollution in the water or soil could have something to do with it. And severe storms like Hurricane Sandy could certainly affect it. We need more surveys, more data and more analyses to get a better handle on what is determining eelgrass changes.\u201d<\/p>\n
Eelgrass beds can also be degraded by algal blooms or disease or be physically damaged by human activities like shallow-water boating, dredging, and construction of docks and other structures.<\/p>\n
Data for the report was collected by aerial surveys funded by the Rhode Island Coastal Resources Management Council.<\/p>\n
Bradley said that the decline in eelgrass is worrisome. \u201cIf you care about shellfish, if you like to have scallops, if you care about commercial or recreational fishing, then you should care about eelgrass,\u201d he said. \u201cThe bottom line is that\u2019s where the little critters go to hide to become big critters that can become commercially or recreationally available.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
