Coastal sandplain grasslands, besides referred to as nautical grasslands, New England sandplain grasslands, or planetary medium tall graminoid vegetation, are low-lying habitats that are dominated by grasses, and occur throughout a lot of coastal New England. This habitat has been shaped over time by a unique frigid history, maritime climate, and periodic disturbances such as arouse and salt spray 7,13. Soils in this habitat are comprised of flaxen loam, typically nutrient poor and well-drained 13. common grasses include short blue shank, hairgrass, Pennsylvania sedge, and poverty grass 5,11. Sandplain grasslands host a count of rare plants and animals, such as bushy rockrose and short-eared owl 2,6.
Sandplain grassland habitat increased in extent with the authorize of pitch pine-oak forests during european village, which began in the early 1600s, and by 1850, closely half of coastal Massachusetts sandplain habitat was converted to agriculture 6,9. dirty alterations from farming stimulate growth of non-native shrubs and threaten the re-establishment of native plant species 4,10. Sandplain grasslands border heath and shrubland habitats, which are found further inland and at higher elevations, but are often blend with grasslands 11 .
Pre-colonial sandplain grasslands were naturally maintained through salt, wind, and fire photograph 7,13 ; nowadays, they are far maintained by positive burns and mowing 12, although these activities may be decreasing 4. Fires were historically prevailing in coastal New England sandplains, and were known to be used by native Americans, which likely contributed to the sustenance and expansion of coastal grasslands 9. coastal sandplain grasslands are presently listed as “ Critically Imperiled ” by the state of Massachusetts 11. additionally, Massachusetts has identified 71 Species of Greatest Conservation Need ( SGCN ) that occur in grassland habitats 8.

Climate Impacts
Rising sea levels will likely impact coastal knit grasslands. Salt water intrusion and increasing storm surge may inundate coastal grasslands and disrupt native vegetation. On the early hired hand, this habitat has the ability to adapt by migrating inland, arsenic long as it can continue to be maintained by salt spray, wind, and ardor exposure, and is not outpaced by the rate of sea horizontal surface ascent 1,7,13. The importance of fuel in these ecosystems may have declined as a result of bedwetter climate conditions ascribable to increasing precipitation 12. future changes in precipitation will effect the relative survival of native and non-native grasses, which will create both challenges and opportunities for adaptive management 3. extra stressors such as exploitation, agricultural runoff, and invasive species will besides compound the effects of warming temperatures, increasing precipitation, and rising sea horizontal surface.
