Restore or create traditional water meadows
A 1998 review of case studies in France, gathered from published and unpublished literature (Muller et al. 1998) reported one French study showing an increase in plant species richness (from 5 to 10-25 species over four years) on a wet grassland in Brittany following introduction of grazing by Camargue horses (Rozé 1993).

Reduce chemical inputs in grassland management
A 1998 review of case studies in France, gathered from published and unpublished literature (Muller et al. 1998) found no monitoring results from France for the effects of reduced management intensity on agriculturally improved grasslands. Three Dutch studies were cited (including (Berendse et al. 1992)) which showed that stopping fertilization does not cause a rapid increase in plant species richness.
Restore/create species-rich, semi-natural grassland
A 1998 review of case studies in France gathered from published and unpublished literature on grasslands (Muller et al. 1998) found that the restoration process generally takes eight years or more and does not always work as expected. Fifty-one case studies were identified across France (including 16 on wet grassland). Most were not discussed in detail. On chalk grassland, one study showed an increase in a plant species diversity index over three years in response to mowing (Dutoit 1996). On meadows degraded by engineering work or ski tracks, seven studies were found demonstrating that grasslands can be artificially re-created, but that it takes many years. One study, for example, demonstrated that achieving vegetation similar to the original vegetation took nine years (Bédécarrats 1991). Another demonstrated how, over eight years, sown species gradually disappeared to be replaced by a newly created grassland with a different plant community from the original (Maman 1985, Coin 1992).
