Deserts and drylands appear to be rough and tough but are very fragile. Extreme temperatures, intense sunlight, limited rainfall, and low fertility make natural recovery of these areas very slow after disturbance. Conditions suitable for plant establishment occur only infrequently. It may take hundreds of years for recovery to take place without active intervention. Understanding the nature of the history of the site and the changes that have taken place is critical. Soil treatment with pitting or roughening the surface can help and is often all that can be done. Seeding with locally collected native plants is not cheap and will often fail completely. Container planting with irrigation is even more costly but can be the key to starting recovery.

Selected papers and reports — technique
Techniques for desert restoration have been tested and some have worked well. Soil treatment, water harvesting, mulch, seeding and container planting can work. Irrigation is almost always required and the most efficient systems should be considered.

Selected projects and guidance
Reviewing the techniques used locally or in other areas with similar soil and climate is a good first step. Understanding the history of the site and the changes that have taken place is critical. It is important to consider what is already known, rather than simply charging ahead with a costly program that may fail completely.
