Douglas fir (Pseudotsuga menziesii) is a another classic example of the right plant in the wrong place. An important component of our forestry industry, Douglas fir is prized for its durability and resistance to decay.
But, unfortunately, Douglas fir seed is very lightweight and can spread long distances by wind—up to about 10 km. This means that unwanted Douglas fir seedlings can appear well into the Park, with no commercial value but considerable weed potential.
Particular areas of the Park at risk of Douglas fir establishment include the southern end of the Park, from Marahau to Stilwell Bay, and the Canaan Downs/Moa Park area. If you spot a young seedling you can pull it out, but in the case of larger trees please report them.
