Observations on Peat Growth and Long-term Peatland Cycles in Scotland
Over long timescales peat bogs are dynamic entitites, going through periods of growth
and erosion. Page 9 of this document also shows how the type of vegetation cover can
indicate whether a given bog is actively sequestrating carbon, only storing it, or actively
liberating it: a topical issue.
However peat bogs can be complex and, on a landscape scale, all the above can be
happening in different places so it can be difficult to determine the overall impact of the
peatland on the carbon budget.

From Pools to Peat Hags: the Later Stages of Peat Bog Development
A new hypothesis for the orientation and expansion of pools in temperate blanket and
raised bogs
The origin of the pools which occur in regular patterns on peat bogs (‘patterned bogs’) has
always been a matter of debate amongst peatland ecologists. This paper presents a new
hypothesis for their formation, with two insights:
1. The surface of the bog (the acrotelm) can deform under gravity: on slopes it can form a
regular wave pattern, giving rise to parallel pools; on level ground it deforms randomly, giving
rise to round pools (‘dubh lochs’).
2. Hollows or pools with dense Sphagnum lawns, instead of indicating areas of high peat
accumulation, indicate areas of low or negative accumulation – which is one reason why pools
expand over time. This is counter-intuitive.
