The IFA Farmland Code Of Conduct

Respect farmland and the rural environment
Do not interfere with livestock, crops, machinery or other property.
Guard against all risks of fire, especially near forests.
Leave all farm gates as you find them.
Always keep children under close control and supervision
Avoid entering farmland containing livestock. Your presence can cause stress to the livestock and even endanger your own safety.
Do not enter farmland if you have dogs with you, even if on a leash, unless with the permission of the landowner.
Always use gates, stiles or other recognised access points and avoid damage to fences, hedges and walls.
Take all your litter home.
Take special care on country roads.
Avoid making unnecessary noise.
Protect wildlife, plants and trees.
Take heed of warning signs - they are there for your protection.
