Karrbarda (Long Yam) on scratchpaper
The karrbarda used to be a very important bush tucker. It grows in sandy soil and sometimes gets as big as half a meter long. The time to dig karrbarda is in yekke (early dry season) when the leaves are still green but the flowers and fruits are dry. Today we use a crow bar but the old people used a kunbarlkbu (digging stick). The best digging stick is made from mandubang (ironwood). When you dig up the karrbarda you put the narrow part at the top back in the ground to grow again. The old people used to go a favourite place for digging karrbarda and camp for a couple of nights.
