Summary

The extent of compositional difference in assemblages needed to designate separate threatened communities is very subjective, and may be increased by uncertainties over resident status of some taxa. Large-scale changes that have received particular attention include those associated with deforestation, conversion of land for agriculture and agroforestry (typified by large areas of lowered-diversity monocultures replacing previous high-diversity natural communities), and urbanisation (including industrialisation) and recreational activities. The importance of landscape structure and abrupt changes between adjacent habitats is illustrated well by studies of Lepidoptera across such boundaries, for example between contrasting woodland and abutting open ground – with the ‘edge’ considered as a distinct third environment, and so incorporating a variety of both anthropogenic (disturbance) and environmental factors in site suitability. The principles lead to many individual management measures that harmonise or restore natural values – including wellbeing of Lepidoptera – with human uses.
