CIR 1484: Use of Amphibians as Indicators of Ecosystem Restoration Success

Figure 6. Diagram showing how the proportion of an area occupied (PAO) by various amphibian species might differ in four habitat types. Arrows indicate direction of increasing hydroperiod from very few days in pineland habitat to almost permanent inundation in cypress habitat. The size of the circle around each amphibian species indicates the PAO for that species in that habitat. Little Grass Frogs (pink circle) are relatively abundant in pine-lands, but decrease in terms of PAO in the wetter habitats. Greater Sirens (red circle) are only found in wetter habitats, but reach their largest PAO in open marsh habitats.
