Grazing
management is nothing new to the islands there are many examples in the past of
rotational or managed grazing systems that have been successful. But now with
the advent of reliable electric fencing systems two and three wire electric
fencing can now be used to split up camps and make better use of the feed on
offer.
There are now
several experimental grazing management systems set up on East and West Falkland.
These systems use an intensive method of grazing through 8 to 15 paddocks during
summer. Other camps are then spelled and used during joining and lambing. By
doing this feed on offer to stock is of higher quality and rested paddocks can
be used more efficiently in a yearly rotation. Benefits to date are being seen
in easier stock handling due to more contact, maintenance of animal production
and healthier pastures.
Changes in
plant species and the production of sheep in these managed grazing systems are
being monitored to demonstrate the longer term benefits of this management
system.
A simulated grazing trial carried out at
Fitzroy has demonstrated over several years that managed grazing can lead
to 2-3 times as much dry matter production as a set stocking system in the
Falkland Islands.
In 2008 the DOA brought in grazing management
specialist Jim Gerrish to continue the training of DOA staff in grazing
management skills.
