Tussock and sedge
Chionochloa (tussock) is a hardy grass species with the ability to survive for hundreds of years in a range of soil conditions, including the exposed environment and high altitudes of the New Zealand high country. The soils of FLOCKHILL support two specific endemic tussock species; red tussock, with its rustic tones; and snow tussock, in shimmering greenish-gold. Both these tussocks play important roles at FLOCKHILL, helping to maintain life and biodiversity on the high country property. While red tussock provides an important barrier for wetlands and helps to reestablish wildlife habitat, snow tussock collects and retains water and provides habitat for a range of invertebrates. There are also many varieties of sedge around FLOCKHILL’s swamps, streams, and waterways; playing a critical role in wetland ecosystems by aiding erosion control and removing removing pollutants. Animals—both aquatic and and amphibious—depend sedge for their fruits, shoots and tubers; while fish depend on them for cover in waterways. The Carex also provides nesting material and sites for birds as well as habitat for invertebrates.
Trees
Many indigenous trees thrive in FLOCKHILL’s distinctive environment, with unique properties and qualities unmatched by any other species. The Matagouri, the only native thorny tree only found in New Zealand, offers shelter to sheep during snow and also relief from the hot summer’s sun. Flowers from the Mānuka tree provide an important source of pollen and nectar for native bees, flies, moths, beetles and geckos, and with the Kānuka tree, it provides shade and shelter from the wind to protect slower growing native plants. Towering Mountain Beech and Black Beech trees are a common sight at FLOCKHILL, hosting the beech scale insect which produces honeydew for native birds and insects. Mountain Beech forests also host endangered native mistletoe species that are facing risk due to possum browse. The evergreen Kohuhu tree is a common sight in New Zealand, but treasured for feeding native birds like the Kea and producing gums with medicinal qualities.
Shrubs
FLOCKHILL is home to a nationally endangered wildflower, the Everlasting Daisy. Often found in inland Canterbury, the rare climbing shrub provides an enchanting and vibrant burst of life, thriving alongside river gorges and terraces. Another endemic shrub is the fast-growing Koromiko, known as the New Zealand willow, which provides low shelter for other flora and fauna. Also thought to have medicinal qualities, Koromiko leaves have been used for a range of ailments.
