Area of land that the organization reforested during the reporting period.
Organizations should footnote all assumptions used.
This metric is intended to capture the area of land reforested, a proxy for the efficiency of management measures, natural regeneration, and the magnitude of effects of the reforested area on surrounding areas. Analysis of area reforested often suggests needed management adjustments as a result of biotic and abiotic factors such as diseases and droughts. Organizations are encouraged to closely monitor deforestation and its causes through remote sensing data, tracking the evolution and speed of reforestation over time.

IRIS Metrics Work Better in Sets
To use IRIS metrics—and the resulting data—to understand impact performance, IRIS metrics should be used and analyzed in generally accepted sets and according to well-defined objectives. IRIS+ gives you access to generally accepted Core Metrics Sets aligned to common Impact Themes and Sustainable Development Goals (SDGs).
