Management and Restoration
Management and restoration of lowland wetlands
are based on three guiding principles - grazing, management of
water levels, and measures to reduce or eliminate harmful nutrient
Changes in farming practices mean that many wetlands are no
longer grazed. As a result they become dominated by scrub, tall
grasses and rushes with few other species. One of CCW’s aims is to
encourage good grazing practice.
Management and restoration activities on lowland wetlands are
usually geared towards maintaining a high and stable water level,
with low levels of nitrogen and phosphorus. Drainage leads to the
release of carbon from peat and loss of species. Restoring water
sources is a priority, but whole catchments will have to be managed
sympathetically if this is to succeed in the long run.
Too many nutrients
The soil in the most important wetlands is often acidic and has
few nutrients. Too many nutrients like nitrogen and phosphorus
causes some plants to grow too strongly, smothering others. This is
called nutrient enrichment and can be caused by too much use of
fertilisers, sewage, silage, waste and pollution in the atmosphere.
The best way to deal with nutrient enrichment is to tackle the
