maintain for Spotted Crakes would seem to
be consistent shallow water areas that do not
dry out during April–September, and which
retain relatively open vegetation, although
the type and height of the vegetation seems
less crucial. It would seem advisable, for this
reason, to remove the most rank and
aggressive vegetation, and grazing by
livestock of peripheral areas late in the
season may be an advantage, although it is
difficult to see how cutting machinery or
grazing stock will affect the wettest core
areas that Spotted Crake seem to favour.
The data presented here are initial results
from a pilot one-year study. We advocate
further similar studies of the species,
covering birds breeding at other sites whilst
maintaining monitoring activity at Lille
Vildmose, to determine between-year and
between-site patterns of habitat occupancy
and home range assessment. This should
lead to more definite conclusions about
habitat choice and the role of water levels,
for developing a sympathetic management
programme for the species.
