Environmental effects of drainage, drain-blocking and prescribed vegetation burning in UK upland peatlands
Peatlands are important ecosystems for carbon (C) storage, provision of water resources and biodiversity. This paper reviews the hydrological, physicochemical and ecological effects of 3 widespread UK peatland management practices, namely artificial
drainage, drain blocking and rotational heather burning. Relatively little is known about the environmental effects of rotational heather burning compared with drainage and drain-blocking management, and for all three of these management techniques
there is scarce information on river ecosystem response. The AA. hypothesize some likely effects of basin-scale drainage, drain blocking and heather burning on stream ecosystems and illustrate these with a schematic model. Such a holistic consideration of peatland

properties and is viewed as being analogous to, and governed by, essentially the same properties as artificial field drains. Close similarities in regolith characteristics and response to rainfall in the two areas are noted.

Erosion and natural revegetation associated with surface land drains in upland peatlands
This paper examines blanket peat catchments in northern Britain and provides data on the erosion and revegetation of land drains and the sediment production from peatland drains. It provides a novel survey of the geomorphology of peat drains
and the first detailed measured comparison of sediment flux from open drains, intact peat subcatchments, drains that have been blocked by peat dams and sediment production from the catchment outlet.

A review of pedogenic zonation in well-drained soils of the Southern Circumpolar Region
The objectives of this paper are : 1) to summarize data for major soils, in particular the well-drained or zonal soils| 2) to examine soil-forming processes along a bioclimatic gradient| 3) to refine Tedrow's (1977) pedologic zones| and 4

Cressey Dymock and the draining of the Fens: an early agricultural model
In England under the Protectorate, new patterns of land-ownership and the draining of previously waste lands made more urgent the need to evolve rational methods of land use. The work of Cressey Dymock, one of the Hartlib circle, is presented

The aims of this study were to assess the infiltration capacity of some extensive soils in Ireland and also its spatial and temporal variability. Infiltration capacity was measured using double-ring infiltrometers at one poorly drained, one
imperfectly drained and eight freely drained sites. Discussion of the results of two series of measurements performed in winter and summer, in 1988 and in 1995-1996. A pronounced seasonal effect is highlighted and therefore a significant risk of overland flow
