Tasmanian police have charged seven people over violence in the southern forests last week.
Three of them have been charged with common assault and four with trespass.
It is alleged forest workers attacked a car containing two conservationists which was blocking a road in the Upper Florentine Valley.
It is also alleged the conservationists were trespassing in an exclusion zone.
All seven have been charged by summons and will appear in the Hobart Magistrates Court at a later date.
