.... In the 1990s, the U.S. Long Term Ecological Research (LTER) Network embraced these challenges and expanded to include sites in urban centers, adding the Baltimore Ecosystem Study, Maryland, and the Central Arizona-Phoenix, Arizona, sites in 1997. Since then, other LTER sites, particularly coastal sites...
