A protective plot is nothing you can claim. Those plots was created to protect areas outside existing (claimable/buyable) plots. With this feature you can protect an area outside the plots if you don't have the the protect area outside plots feature enabled in the configuration file.

Creating a protective plot with PlotGuardian is pretty straightforward and the only thing you have to do is to mark two selections (the plot corners) and then type the creation command.

Please take a look at the image below. To create a protective plot the diamondselector tool is required to mark the corners of a plot. The corners define the protective plots area and create a cuboid, just as big as the grass cuboid in the image. This means the selections must be at the opposite corners.

To make a first selection you take the diamondselector and left-click on the desired corner. To mark the second selection you do the same thing but right-click the second block this time. Please look at the example image below for further explenation.

When you have done this you can simply type the creation command (/plot protect <plotname>), <plotname> defines the protective plot name and can be replaced with any word. For example protective13. Please note that this command above will also calculate the height between both selections and the plot will be created within those two selections. In the example image below the plot will only cover the grass layer.

To make life a bit simpler there is another feature to easily adjust the Y-height of the plot by simply adding two arguments to the command. For example, if you type /plot protect protective13 0 255 a protective plot with the name protective13 will be created and stretch all the way from bedrock to the highest buildable block.
