Shanna has travelled from the USA to study for a Bachelor of Science in Environmental Geology at the University of Otago in New Zealand.  When she’s not studying she likes to hike, paint and read.

 

Left over from the mining processes are mine channels that were dug into the ground, which created steep slopes. The mining had also left large areas barren and exposed. Both of these factors lead to a lot of sediment runoff, which is washed down the slopes and then fans out on the flat ground at the bottom.

“Left over from the mining processes are mine channels that were dug into the ground, which created steep slopes.”

The old mine is in Central Otago, which is an arid region, and this leads to salt encrustations forming on the fans of runoff. Some tiny, endangered salt-tolerant plants actually thrive in this environment! Because they are so rare and endangered, the Department of Conservation in New Zealand made the old mine site a Scientific Reserve. Luckily, there are no toxic elements exposed by the mining, so the site does not need intensive remediation. It’s just really bare and really salty, and that counter-intuitively created a safe haven for some unique plants.
