SUMMARY
Examþles of results of the vegetation survey of a
highland common range and a lowland farm.

In order to demonstrate the íinal results
and the practical value of the vegetation
research program in Iceland two examp-
les are given: One from a highland range
in South-Iceland extending from 200 to
1200 m elevation. The calculations are
made separately for each 200 m elevation
belt. The results are presented here on
plant community level and are shown in
tables 1 to 5.
Table 2 shows four calculations of the
carrying capacity of the land range with
varying feed requirements of the sheep
due to different length of the grazing sea-
son, different weight of the ewes, weight
gains of ewes and lambs and different
fertility of the ewes.
The other example is from a lowland
farm in the South-vestern part of Iceland,
including vegetational data on plant
society and plant community levels, car-
rying capacity and data on arable land on
the farm.
