The variety of ecosystems present across the park create niches for many special plants. Some of these plants are unique to the park and are quite rare. Others, such as northern rātā, are less abundant as a result of the presence and activities of humans and browsing animals for many decades. Both rātā and mistletoe will be great indicators of ecological progress as the park is transformed over the next 30 years, because each has been in steady decline due to the aforementioned factors. As those factors are removed or controlled, these plants should begin to thrive again. Keep an eye on this page as we add information about many of the rare and threatened species in the park.
