According to a U.S. National Research Council report in 1994, using conventional monitoring methods and data, it is impossible to determine whether U.S. rangelands are improving or degrading. They recommended an approach based on multiple indicators of basic ecosystem processes.

Improving soil health and building new soil



Soil health is vital to ecosystem health. Today the U.S.A.'s biggest export, in tons and dollar value, is eroding topsoil. What topsoil remains is often drenched with chemicals and nearly devoid of life. This stops the soil-building process.

Fortunately topsoil can be grown fairly quickly. Even land so damaged it has no topsoil can be restored.

Desertification: what it is and how to fix it

Why conventional "solutions" fail to reverse desertification; proven methods that work.

Desertification is the process by which formerly productive land (grasslands, savannas, forests, and farmland) becomes desert.

How to heal damaged land

Index of articles and links

Grasslands and grazers evolved together in the world's seasonally dry and arid (brittle) environments. Healing this land usually involves managing livestock to perform the ecosystem functions once performed by wild animals. This works even on severely damaged and eroded land, and in places where no topsoil remains.

Revegetating soilless land

Even land that has lost all its soil -- or where no soil ever existed -- can be revegetated. Using the method shown, up to a foot of soil can be created in three years, even in arid areas.

Animal impact: how trampling and disturbance benefit grassland ecosystems

Grasslands and dryland ecosystems are adapted to, and dependent upon, disturbances such as grazing and trampling.

Landscape brittleness: how "good" management can harm land

Summary: Landscapes in different climates respond very differently to similar management. Management that doesn't suit the landscape is the leading cause of desertification worldwide.
