Birds, insects, and reptiles are common even in the desert. A species can be native to an ecosystem or region, without naturally occuring in an small locality.
If humans manage water more efficiently than nature would have in this locality, it stands to reason that the resulting local ecosystem would be able to attract and support more native wildlife.
This is observable and provable for golf courses which manage their resources with a focus on limiting their natural resource use and increasing local biodiversity.
You just hate golf courses, which is fine, but you sound pretty uninformed.
