I am pretty sure that huckleberry patches at higher elevations were also "owned" by family groups, though I don't think they were intensively managed.
Camas was an important staple for Coast Salish peoples. Blue camas (Great Camas and Common Camas) beds were individually owned and passed down from generation to generation. Camas crop maintenance and harvesting can be termed semi-agricultural. Each season, families cleared their plots of stones, brush and weeds, often using fire in controlled burning. Harvesting the bulbs involved lifting small units of sod, removing the bulbs and replacing the sod layer. Camas bulbs were steamed in pits. The cooked bulbs were soft and sweet and frequently used to sweeten other foods such as soapberries. Care was taken not to harvest the similar looking, toxic Death Camas which usually grows in proximity to the Blue Camas - http://www.nps.gov/sajh/naturescience/the-cultural-prairie.htm
