The best way to observe forest succession is to compare the prevalent plant life from disturbances in the same area. On our hike to Mt Aspiring on the Rob Roy Glacier track, we hiked along through a mostly filled forest, although we could observe rockier patches where disturbances like landslides, heavy wind and flooding had occurred. Attached is one of the more recent disturbances that we saw, evident by the most common types of plant life and lack of shrubs and smaller plants. Some of the plants we found in the filled regions of the forest were tree fuchsia , silver beech, lancewood and pittosporum, but these plants were not around in the earlier successions. In the space where the photo was taken, tutu and young beech trees were present, but likely will be washed away after the next heavy rain and flood. Most common was lichen and moss growing on the rocks, beginning to break down the boulders and rocks stacked from a landslide or 'slip'.
Glaciers carve out valleys as the move forward and retreat, and the valley floor is obviously full of nutrients because of the luscious forest we encountered. These valley walls can be steep, though, which makes it easier for landslides to occur with erosion because most of the nutrient soil is in the bottom of the valley so plants have little to hold on to. Above is what it looks like after a landslide and as plants grow back, the most luscious parts will be towards the bottom where lichen have been able to eat away at smaller rocks which have shrunk from tumbling down the sides of the valley. Tutu and young beech plants are some of the first to grow back, but koromiko, celery pine, wine berry and broadleaf come next after the conditions can allow for plants to grow strong without being knocked down.

I think it might be Anthosachne solandri.

The flowering plants (angiosperms), also known as Angiospermae Lindl. or Magnoliophyta, are the most diverse group of land plants. Angiosperms are seed-producing plants like the gymnosperms and can be distinguished from the gymnosperms by a series of synapomorphies (derived characteristics). These characteristics include flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure; they are fruiting plants, although more commonly referred...
