The phrase "area of suitability" is correct and usable in written English.
It can be used in contexts where you are discussing a specific region or zone that is deemed appropriate or fitting for a particular purpose or activity.
Example: "The environmental assessment identified several areas of suitability for the proposed wildlife reserve."
Alternatives: "zone of appropriateness" or "region of fitness".
This study explored the application of geographic information systems (GIS) in modeling the locational and topographical aspects to identify areas of suitability.
Areas of sylvatic suitability are restricted to Central, East and Southern Africa, but commonly overlap areas of suitability for domestic cycles.
Ae. aegypti is predicted to occur primarily in the tropics and sub-tropics, with concentrations in northern Brazil and southeast Asia including all of India, but with relatively few areas of suitability in Europe (only Spain and Greece) and temperate North America.
Results from the four studies of tree species indicated substantial loss of area of climate suitability for the four subalpine species by 2100.
One of the most striking aspects of our results is that the primary area of predicted suitability in the United States, the Everglades, is the only place that the pythons have ever been found to have established populations.
The area of climatic suitability for every Cyclamen species is predicted to decrease.
Over the next 50 years we predict a northward shift in the area of climatic suitability, with many areas of current distribution becoming climatically unsuitable.
Many species show no future area of climatic suitability and these are considered to be at high risk of extinction due to climate change.
The area of climatically suitability value above 0.4 from the LGM prediction (430,602 km) was larger than that from the current prediction (311,860 km).
The area of climatically suitability value above 0.8 at LGM (70,032 km) was also slightly larger than the current most suitable habitat (67,329 km).
