Planting in conservancy areas

Hi everyone, We have a project in a greenfield, it's conservancy areas consist of vegetation that is mostly dry grass. For this reason most of the protected areas are originally designed for landscaping. Could we plant native or adaptive plants that require low irrigation in these spaces since the current scarce vegetation and deteriorated ground will benefit greatly from a more dense and colourful vegetation, take into consideration that fauna will also take advantage of these plants. Areas outside the allowed disturbance space will be properly protected. Thank you!
