Key messages

  • One study evaluated the effects on peatland vegetation of reducing harvest intensity (of wild biological resources). The study was in a bog.
  • Moss cover (1 study): One replicated, controlled study in a bog in New Zealand reported that Sphagnum moss cover was higher, three years after harvesting, when some Sphagnum was left in plots than when it was completely harvested.

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. A replicated, controlled study in a bog in New Zealand (Whinam & Buxton 1997) reported that incompletely harvested plots regained Sphagnum moss cover more quickly than completely harvested plots. In plots where 30% of harvestable Sphagnum was left in place, Sphagnum cover was 90% after three years. In contrast, in plots from which all Sphagnum had been harvested, Sphagnum cover was only 50% after three years. No statistical tests were carried out and details of methods were not reported.
