Models of Vegetation Dynamics in Semi-arid Vegetation: Application to Lowland Central Otago, New Zealand
New Zealand Journal of Ecology (1997) 21(2): 129-140 ©New Zealand Ecological Society these conceptual extremes should be seen as being endpoints of a range of possible situations, and not as discrete alternatives. It is therefore unlikely that an observed field situation would be completely described by any one of the models alone. More recently developed models use the conceptual extremes as c...
متن کاملPost-pastoral changes in composition and guilds in a semi-arid conservation area, Central Otago, New Zealand
Changes in the vegetation of Flat Top Hill, a highly modified conservation area in semi-arid Central Otago, New Zealand, are described four years after the cessation of sheep and rabbit grazing. Unusually moist weather conditions coincide with the four-year period of change in response to the cessation of grazing. Between 1993 and 1997, the average richness and diversity (H’) of species increas...

New Zealand Journal of Ecology (1995) 19(2): 175-194 ©New Zealand Ecological Society temperatures among the most extreme recorded in New Zealand (Maunder, 1965). The Central Otago region has a complex history of disturbance. Post-glacial forest may never have extended to the drier basins of Central Otago, and the establishment of grassland, possibly through natural fires, preceded human settlem...
متن کاملThe Landscape as a Unit for Rangeland Inventory in Arid and Semi-arid Regions of Iran
Severe range degradation was critically extended in many region of Iran and caused many rangelands were restricted and interwoven with croplands in a complex system. Therefore, rangeland planning and inventory as an isolated activity has become almost impossible. Current landscape planning involves contributions of different social organizations often with different interests and with different...
متن کاملQuaternary lacustrine deposits in a high-energy semi-arid mountain environment, Karakoram Mountains, northern Pakistan
impressive Quaternary lacustrine deposits are present as terrace remnants throughout the Karakoram Mountains, northern Pakistan. They are mainly the result of damming of drainage systems during glacial advances or by catastrophic mass movement deposits. The longevity of most lakes is relatively short, in the order of years to tens of yeaa, but sedimentation rates are extremely high as a consequ...
