A more thorough explanation:

Disturbance of common refers to a wrongful interference with someone else's right to use a common property. This can happen when someone puts their cattle on the land without permission or when they put animals that are not allowed on the land, like hogs or goats.

For example, if a group of farmers share a pasture for their cows to graze on, and one farmer puts more cows on the land than they are allowed, it can cause a disturbance of common. This is because the other farmers' cows will not have enough grass to eat, and their right to use the common land is being interfered with.

Another example could be if a group of people share a park for recreational activities, and one person decides to set up a large tent in the middle of the park, blocking others from using that area. This would be a disturbance of common because it is interfering with the other people's right to use the park for their own recreational activities.
