Pollen analysis (Davis, 1989) has often been used in retrospective monitoring. An analysis of the relative proportion and incidence of pollen from different plant species found in deposits of peat or other substrata, together with other sources of information, can be used to construct a picture of ecological processes that have occurred over the last few thousand years (Fig. 2). 19 Ecological monitoring increasing rate of mire formation increasing alder carr formation loess-rich topsoil surface erosion of conservation woodland reducing tree and shrub diversity 13,000 BRONZE AGE 2,000 1,000 AD BC 1,000 2,000 NEOLITHIC 3,000 4,000 5,000 6,000 7,000 some mires formed LATE GLACIAL 12,000 tundra 11,000 ROM-BRITISH IRON AGE MESOLITHIC deposition; active erosion 10,000 PRE-BOREAL (improving) MODERN AND MEDIEVAL last phase of loess 9,000 heath expansion 8,000 BOREAL (continental) woodland clearance, 7,000 heath and grassland 6,000 ATLANTIC (warm, damp, climatic optimum) immigration of species 5,000 oak, hazel 4,000 SUB-BOREAL (possibly more continental) birch/pine 3,000 woodland 2,000 oak, hazel, alder, lime, elm,willow max.

The Antarctic Treaty included no specific provisions on mining. The 1988 Convention on Regulation of Antarctic Minerals Resource Activities (CRAMRA), would have allowed exploration for minerals and controlled mining, had it not been unsuccessful because of a lack of signatories. More recently, there was the establishment of the Protocol on Environmental Protection to the Antarctic Treaty, 1991. This prohibited all mineral resource activities but also called for regular and effective monitoring to allow assessment of the impacts of ongoing activities on the Antarctic environment and associated ecosystems.

The Community and Member States shall cooperate to ensure consistency of monitoring and measurement methods. If for no other reason, there was an overwhelming case for ecological monitoring in Europe because of the EEC’s ambitious plan to encourage development in the poorest regions of Europe. The Worldwide Fund for Nature (WWF) and the Institute for European Environmental Policy (IEEP) warned that governments were hastily assembling major but possibly unviable schemes, the impacts of which had not been considered sufficiently.
