This is a delicate habitat that regenerates veryslowly – so with the loss of the peat, you also lose the wild flowers Environmentallyand specialist wildlife that depend on them. 96% ofnative peat bogs have now disappeared and the Friendly Gardeningremaining 4% are under threat due to demand for peatfrom gardeners and growers. This demand is nowthreatening to cause damage to peat bogs in Europe aswell. Similarly, damage is being caused by moss collection from the wild, for hanging baskets, rather than from managed sources. If considering furniture in the garden, an eco-friendly gardener would ensure that furniture is not made usinghardwoods taken from the wild, but those grown in a sustainablymanaged forest.Consideration also needs to be given to the chemicals inpreservatives and paint used to treat and colour the furniture andthe implications these may have in contaminating the surroundingenvironment.
