How to Reforest a Steep Slope Without Swales or Irrigation

12:35 minute video shows how native grasses can be planted in lines or curves to help slow down water enough to help it penetrate a hillside slope without disrupting the soil integrity.

The lady explains her choices of native tree species interplanted within the native grass, how the evergreens provide shade and protection to the rainforest species. She explains how the grasses help protect her saplings from freezing and baking hot weather. However she comes along periodically to weed away vines and grasses to prevent them from strangling the saplings, then uses the weeded materials as free mulch to further lock in moisture.

This example is in Australia so she also explains how the different species will support local natives including koalas.
