. A series of biennial reports from the U.S National Research Council have reviewed the progress of CERP the fourth report in the series released in 2012 found that little progress has been made in restoring the core of the remaining Everglades ecosystem; instead most project construction so far has occurred along its periphery the report noted that to reverse ongoing ecosystem declines it will be necessary to expedite restoration projects that target the central Everglades and to improve both the quality and quantity of the water in the ecosystem to better understand the potential implications of the current slow pace of progress the report assessed the current status of ten Everglades ecosystem attributes including phosphorus loads peat depth and populations of snail kites birds of prey that are endangered in South Florida Most attributes received grades ranging from C (degraded) to D (significantly degraded) but the snail kite received a grade of F (near irreversible damage) the report also assessed the future trajectory of each ecosystem attribute under three restoration scenarios: improved water quality improved hydrology and improvements to both water quality and hydrology which helped highlight the urgency of restoration actions to benefit a wide range of ecosystem attributes and demonstrate the cost of inaction Overall the report concluded that substantial near-term progress to address both water quality and hydrology in the central Everglades is needed to reverse ongoing degradation before it is too late. . Iberia Madrid Prior to urban development of the South Florida region pine rocklands covered approximately 161,660 acres (654.2 km2) in Miami-Dade County Within Everglades National Park 19,840 acres (80.3 km2) of pine forests are protected but outside the park 1,780 acres (7.2 km2) of pine communities remained as of 1990 averaging 12.1 acres (49,000 m2) in area the misunderstanding of the role of fire also played a part in the disappearance of pine forests in the area as natural fires were put out and pine rocklands transitioned into hardwood hammocks Prescribed fires occur in Everglades National Park in pine rocklands every three to seven years. The underlying bedrock or limestone of the Everglades basin affects the hydroperiod or how long an area within the region stays flooded throughout the year Longer hydroperiods are possible in areas that were submerged beneath seawater for longer periods of time while the geology of Florida was forming More water is held within the porous ooids and limestone than older types of rock that spent more time above sea level a hydroperiod of ten months or more fosters growth of sawgrass whereas a shorter hydroperiod of six months or less promotes beds of periphyton a growth of algae and other microscopic organisms There are only two types of soil in the Everglades peat and marl Where there are longer hydroperiods peat builds up over hundreds or thousands of years due to many generations of decaying plant matter Where periphyton grows the soil develops into marl which is more calcitic in composition.
As of the 2000 census the urbanized area had a land area of 1,116 square miles (2,890 km2) with a population of 4,919,036 for a population density of 4,407.4 per square mile (1,701.7 per square kilometer) Miami and Hialeah (the second largest city in the metropolitan area) had population densities of more than 10,000 per square mile (more than 3,800 per square kilometer) the Miami Urbanized Area was the fourth largest urbanized area in the United States in the 2010 census. ! .
