The series had a simple formula (as recapped on the show's fan website):
The Junior Forest Rangers live in a "Never-never land, unmarred by schools or parents, in which the only rules are the rules of conservation." Though the kids always manage to get involved in trouble, there is little violence involved, mainly just threats from wayward adults who put themselves in danger because they didn't heed the advice of the Chief Ranger. In the end, the wrong-doers are usually brought back to the Chief Ranger's (Department of Lands and Forests) office and scolded, but are rarely handed over to the law.
I remember watching this show avidly, cringe-worthy though I'm sure it would seem today. Some things are best left to the rose-coloured memories of childhood, LOL!
And yes, that's Gordon Pinsent as the RCMP officer. The Forest Rangers was his first role in a major TV series.
