, low natural waterfalls and water abundance that flow from mountains to valleys has make wonderful beauty in this region.
The top design alternatives were regionally appropriate vegetation
Previous research in Arizona found that plant species composition was not as important for black rail habitat selection as appropriate vegetation
structure (high stem densities and canopy coverage) and substrate characteristics (Flores and Eddleman 1995).
The Purple Swamphen (Porphyrio porphyrio) is a medium sized water bird (Ali 1981) which lives in marshes, lagoons, and reservoirs with appropriate vegetation
