Financial resources for protected areas increased from 3.4 pesos (0.3 USD) per hectare in 2001 to 12.7 pesos in 2006 (roughly 1 270 pesos or USD 98 per km2). Figure 5.6 shows total federal budget spending on protected areas from 2001 to 2011. An analysis by Figueroa and Sanchez -Cordero (2008) found that 37 protected areas (54%) were effective, 16 (23%) barely effective and 16 (23%) ineffective.
