The relative potentials of six grass cultivars for reclamation of the north-facing 30° slope of a limestone quarry spoil-heap in Yorkshire, UK, were assessed.

The nature of the moorlands of England and Wales is described and a brief outline of their postglacial ecological history is propounded. Emphasis then switches to a particularly critical phase in this evolution, namely the later centuries of the Mesolithic period of the mid-Holocene, when the human groups of the period employed fire as a management tool for vegetation.

The mountainous Kaokoveld of northwestern Namibia contains numerous endemic plants and animals whose ranges, in many cases, extend into the Etosha National Park, an area extremely rich in game. Etosha Pan, the most striking feature of the Park, is bordered on the South by natural springs and artificial waterholes. These provide drinking places for the animals which congregate in large numbers and cause overgrazing and browsing pressure in the area. Migration to regions beyond the Park boundary is prevented by an 850 km-long game-proof fence. The main factors affecting animal populations are anthrax and poaching. Even so, the culling of Elephants becomes necessary from time to time, and the sale of ivory and other products helps to finance the operation of the Park.

An Eelgrass (Zostera marina L.) bed in a very shallow subtidal habitat adjacent to a busy port in southwestern British Columbia, Canada, was the site of experimental transplants. Eelgrass populations were successfully established, using a variety of transplanting techniques, namely cores (plants with the sediment retained around the rhizomes and roots), sprigs (plants from which the sediment had been washed), and sprigs anchored to buried lengths of iron rod. Transplants took place in two sites — (1) a shallow channel that had eroded from the sea into the Eelgrass bed, and (2) at the landward edge of the existing vegetation.
