| Peatlands act as information traps; archives reflecting changes in climate and environment, through pollen assemblages, sediment facies, plant fibre and C14 dating. The investigation of Maputaland peatlands presents an ideal opportunity to understand these changes during the Late Pleistocene and Holocene. The Maputaland peatlands in South Africa could be geographically divided into two distribution areas based on age: The Holocene age peatlands northwards of the Mkuze River inflow into Lake St. Lucia and the Late Pleistocene age peatlands south of this inflow. The grouping of peat thicknesses versus peat ages in a scatter diagram indicates distribution deviations from the ideal accumulation line. These might represent periods of low or negative growth and... |

| There is an exceptional group of alpine peatlands in the world situated in the arid grasslands of the central Andes. The peatlands in northern Chile occur in the most arid part of their range. Members of the Juncaceae are the primary peat-forming plant species. Fresh and mildly saline groundwaters originate from glaciers, snowmelt and rain are the water sources for the northern Chile peatlands. Paleoecological investigations suggest that some peatlands are recent features of the landscape having developed within the last three thousand years or less. These peatlands are unique, extremely fragile water features sensitive to climate changes and human disturbances such as regional mining activity. Much more work is required to develop scientifically based... |
