2. Mixed Planting

This mixed planting (native and exotic species) was designed to be part of the primary windbreak, as well as an extension to the secondary windbreak.  It provides a high back-row, effectively lifting the westerly and NW winds well beyond the arboretum. Two additional rows of E. saligna were initially established for fuelwood (coppiced annually), however the volume of fuel produced far exceeded current demands and so the trees were removed (prunings, old fallen acacias, dropped branches from eucalypts etc. provide a continual source of fuelwood in lieu of the coppice).

Fraxinus pennysylvanica has performed exceedingly well, growing strongly on these shallow ridge-top soils and in competition with adjacent Eucalypts. Planted in 1999 with no losses to-date, the species shows remarkable resilence in dry periods.  In fact, they have required regular pruning to maintain unhindered vehicle access between windbreak rows.
