Hopefully they won’t be a huge threat to the ecology of Tarra-Bulga National Park but it was interesting to spot this crop of potatoes that seem to have become naturalised in a small patch in the park on the roadside along the Bulga Park Rd.
When cyclists from the Great Victorian Bike Ride “ascend” on Tarra Bulga next week they will notice along with the many native plants in flower some attractive looking flowering plants that are in fact not so desirable. One of the most obvious they will see is Creeping Buttercup – (Ranunculus repens). Although there are native Buttercup species this one comes from the Northern hemisphere. As can be seen by the sea of yellow along the roadsides at this time of the year, it has been well established for a long time and has also penetrate to some moist areas deeper in the park resulting in the displacement of native species.
Another weed that is threatening to take over and become more of a pest is Myosotis sylvatica or Wood forget-me-not. There are also native relatives of this plant in existence, but this species is native to Europe and has been introduced to Tarra Bulga from garden escapes. It is popping up all over the roadsides and is threatening to penetrate deeper into the park. Park staff and volunteers are vigilant in trying to remove seedlings whenever they are encountered but the task seems to be getting more difficult.
