Maintaining biodiversity at Cass
A major threat to the native biodiversity in the Cass area is invasion of native ecosystems by woody weed species. UC is currently managing/controlling the following weeds at Cass:
- Douglas fir - this tree specis is invading the grassland and shrublands at CMRA and if left unchecked would become the dominate plant in the area.
- Gorse and broom. These weeds have spread onto Cass from the river corridor and the road and rail networks.
- Russel Lupins – these plants are major ecological weeds in the unique braided rivers of eastern South Island.
- Willows – As these are major environmantal weeds in lakes and river edges and invade wetlands, modifying the stream flows and altering native fish habitats. Currently UC is working on the removal of willows along the entire length of Grasmere stream.
UC is also undertaking mammalian pest control: this includes, possums, deer and pigs.
We control the invasive German/European wasps, by poisoning in late summer each year. This control has led to a noticeable reduction of wasps in the native beech forests at Cass and safer teaching field trips in the area.
History of Cass field station
The Cass Mountain Research Area (CMRA) consists of 1775 ha of eastern South Island mountain land located in the Cass River basin, upper Waimakariri River catchment, North Canterbury. The research area is owned and operated by the University of Canterbury. The CMRA is located on part of the land that was given to the University of Canterbury (as the Canterbury College) by the then Provincial Government as an endowment for the promotion of superior education. The main purpose of the CMRA is to provide research and learning opportunities for UC staff and students.
The CMRA comprises two prominent peaks, Cass Hill (1098m) and Sugarloaf (1359m), as well as river terraces and alluvial fans. The Cass Basin forms part of the mid-Waimakariri intermontane river basin in the central South Island and provides a very wide range of environments - montane grasslands, scrub, riverbed, scree, beech forest, swamp, bog, lake, stream and alpine habitats.
The history of the Cass Field Station is described in the 1977 publication "CASS: History and Science in the Cass District, Canterbury, New Zealand" edited by E. Percival & C.J. Burrows.
