Following advice from the R&A relief may be taken from staked trees under Rule 24-2 on the card.
Removing the rule about staked trees proved to be a more complex issue than first imagined as the following email illustrates.
By removing the Local Rule for protected trees players would no longer be entitled to relief from the trees i.e. the trunk or branches.
However if the stakes were to remain then they would be automatically treated as obstructions due to the fact that they are manmade. This means that if they could be removed with unreasonable effort and without causing damage the stakes would be considered moveable and could be moved without penalty. ( as per Rule 24-) and if they could not be without reasonable effort that stake would automatically considered an immovable obstruction and the player would again be entitled to relief without penalty under Rule 24-2. However this would be from interference from the stake only and not from the tree. As the Rules of Golf would automatically consider the stakes to be obstructions you would not need to put any specific Rule in place, however given the change it would be certainly worth educating your members on this point, for example by clarifying on your notice boards, or by email how the stakes themselves may be treated now the Local Rule has been removed.
