From these, only two works
have formally evaluated the response to precipitation of NDVIderived
surrogates of ANPP in drylands of SE Spain at the local
(Miranda et al., 2009a) and regional (Paruelo et al., 2005) scales.
Miranda et al. (2009a) used NDVI to evaluate the response of ANPP
to controlled precipitation reductions in annual plant communities.
Paruelo et al. (2005) used NDVI to evaluate the differences in
the APAR-precipitation correlation between protected and nonprotected
landscapes.
