Revised Page: Annual Update 2003
 

Note that the data published in the 2002 State of the Nation’s Ecosystems Report as well as the 2003 and 2005 Web-Only Updates have been superseded by the 2008 Report and thus should be used with caution. For the most recent data, purchase the 2008 Report from Island Press.

Can we report trends? Are there other useful reference points?

System Dimensions Updated
Data Available Total Cropland How much land is used directly for production of crops and livestock? Trends 2003
2005
Data Available The Farmland Landscape How much of the farmland landscape is forest, grasslands and shrublands, wetlands, or urban and suburban? Current data only, regional comparison  
Data Inadequate Fragmentation of Farmlands Landscapes by Development How intermingled are croplands and urban and suburban development? No data reported  
Data Inadequate Shape of "Natural" Patches in the Farmland Landscape How much of the “natural” area in farmlands is in patches of different shapes? No data reported  

Chemical and Physical Conditions Updated
Data Available Nitrate in Farmland Streams and Groundwater How much nitrate is there in farmland streams and groundwater? Current data only, federal standard, cross-ecosystem comparison  
Data Available Phosphorus in Farmland Streams How much phosphorus is there in farmland streams? Phosphorus in Farmland Streams Current data only, federal guideline, cross-ecosystem comparison  
Data Available Pesticides in Farmland Streams and Groundwater How many pesticides are found in farmland streams and groundwater, and how often do they exceed federal standards and guidelines? Current data only, federal standards and guidelines
