Moving beyond the ecosystem in ecosystem health report cards

Laumann KM, Nastase EA, Vargas-Nguyen V, Kelsey RH, Carew A, Donovan EC, Fries AS, Spitzer SE, and Dennison WC ·

Early ecosystem health report cards focused on assessing the health of natural ecosystems, producing a “snapshot” of ecosystem health at one point in time. Ecosystem health report cards are used to guide efforts that improve ecosystem health through natural resources manage- ment and stakeholder engagement. Common themes among Report Cards include water quality and quantity and habitat. These indicators are not strictly environmental concerns, though.
