The relationship is expected to be nonlinear asymptotic because 1) the number of foxes available to be culled
is finite; 2) the ratio of boundary to area increases as estate area decreases; and 3) the cull size within different landscapes reflects both the number of foxes available to cull and the culling effort applied, such that as estate area increases, the average effort of a single gamekeeper is spread more thinly until there is a clear need to employ an additional gamekeeper.
People often forget that 20,000 to 40,000 tammar wallabies are culled
annually on the island, Paton said.
If the badger cull does go ahead, less than a tenth of that number would be culled
But it said: "The council does not, however, believe that a badger cull will support this objective and will therefore, not allow badgers to be culled
on land which the Forest of Dean District Council owns, manages or controls.
We have an estimate of the birds to be culled
. We have also, in fact, checked the outward and inward movement of all the birds," said Surendra Gupta, District Magistrate Darjeeling.
The team found a 19 per cent reduction in the incidence of cattle TB in the areas culled
but a 29 per cent increase of the disease in surrounding farms up to two kilometres away.
Councillor Jim Wells wants the Irish to join in the slaughter of the popular duck, which is to be culled
to extinction in the UK.
Stephen Trotter, chief executive of the Wildlife Trust, said: "We don't want to see either cattle or badgers being culled
and we believe the problem could be resolved if we had an appropriate vaccine.
Surviving badgers from a partly culled
group tend to wander over a larger area and may have increased contact with neighbouring cattle, leading to the spread of TB, experts believe.
WELL, we have culled
(killed - word interchangeable) all the squirrels.
Under the experiment, recommended in a report to ministers published by Professor John Krebs last year, all the badgers in a defined area will be culled
, but in other areas culls will be carried out in response to TB outbreaks in cattle.
