biosphere processesbasic ecosystem functions Brittle and nonbrittle environmentsSubmitted by Peter Donovan on Sat, 07/10/2010 - 07:24A new measure of ecosystem function, vital in understanding seasonally dry ecosystems and reversing desertification. Why management that helps some landscapes harms others Index of articles and linksBrittleness is a fairly new measure of ecosystem function that allows us to match land management to what each landscape needs. Desertification--what it is and how to fix itSubmitted by Peter Donovan on Sat, 07/10/2010 - 07:19Why conventional "solutions" fail to reverse desertification; proven methods that work. Index of articles and linksDesertification is an age-old problem. Since writing was invented, people have lamented landscape damage and urged better care of the land. Despite the march of science and billions spent to combat desertification, the world's deserts continue to grow. What is desertification?Fundamental ecosystem processes and how they work: articles and linksSubmitted by Peter Donovan on Fri, 07/09/2010 - 17:40Basic knowledge to help you manage ecosystems successfully. Index of articles and linksBy understanding and monitoring a few fundamental processes that operate in every ecosystem, we can simplify the complexity of natural systems enough to manage natural resources skillfully.
Landscape monitoring for ecosystem healthSubmitted by Peter Donovan on Fri, 07/09/2010 - 17:23Conventional land monitoring can't detect ecosystem improvement or deterioration until symptoms are severe. Presents methods that detect changes early. Index of articles and linksAccording 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 soilSubmitted by Peter Donovan on Fri, 07/09/2010 - 17:10Practical methods based on proven success. Improving soil health and building new soil
Fortunately topsoil can be grown fairly quickly. Even land so damaged it has no topsoil can be restored. Working with soil lifeSubmitted by Peter Donovan on Fri, 07/09/2010 - 17:08Information about the most overlooked and underrated members of land ecosystems. Index of articles and linksDesertification: what it is and how to fix itSubmitted by Peter Donovan on Fri, 07/09/2010 - 14:47Why conventional "solutions" fail to reverse desertification; proven methods that work. Index of articles and linksDesertification is the process by which formerly productive land (grasslands, savannas, forests, and farmland) becomes desert. How to heal damaged landSubmitted by Peter Donovan on Fri, 07/09/2010 - 14:42Index of articles and linksGrasslands 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 landSubmitted by Peter Donovan on Fri, 07/09/2010 - 14:40Index of articles and linksEven 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.
