Urban trees contribute significantly to human health and environmental quality by improving energy conservation, increasing carbon storage, removing air pollutants, moderating urban heat island effects, providing recreation and wildlife habitat and increasing aesthetics and property values.  The quality of life of nearly 80% of the US population is impacted by urban forests (Dwyer et al. 2003). Despite the economic, aesthetic and environmental benefits of urban forests, assessments of the health of this living resource are rare (Cumming et al. 2001).  Monitoring urban forest health is essential to identifying changes within the forest resource as well as providing a foundation for improving resource management practices (McPherson 1993). A protocol was developed to monitor urban tree health in the CAP LTER study area and was used to assess tree health at urban sites that have been monitored as part of the CAP LTER Primary Productivy montoring project and an additional Survey 200 sites. Permanent in the Spring of 2006.
