  1. Designate protected area

    A replicated study in 2000–2012 of 28 protected areas in northeast China (Lu et al. 2016) reported that the area of marsh and swamp within them decreased over time. Statistical significance was not assessed. The combined area of marshes and swamps decreased by 9% between 2000 and 2012, from 8,444 km2 to 7,724 km2. The area of natural aquatic habitats (rivers and lakes) decreased by 16%, from 5,805 km2 to 4,886 km2. The biggest cause of these losses was conversion to cropland (responsible for 39% of the area of marsh/swamp/aquatic habitat lost). The study also reported “degradation” of the landscape-scale structure of marsh/swamp/aquatic habitats in 21 of the 28 protected areas (reported as an index based on metrics such as the size, shape and separation of habitat patches). Methods: Twenty-eight protected areas were studied. They had been established between 1979 and 2003 (22 before 2000). All but one contained areas of marsh and/or swamp. Most were probably freshwater but some were probably brackish/saline (not explicitly reported). Land cover was determined from satellite images taken in summer or autumn 2000 and 2012. Classifications were verified in the field. Rainfall was similar in both years for each protected area (statistical significance not assessed).
