I have also included in the list some of the other species we interplant with as weed suppressing/fodder producing groundcovers/understoreys: 250mm - 450mm Rainfall (between drip/leeaky hose irrigated/broadacre unirrigated fruit/tree crops etc.) Acacia saligna (medium shrub) Acacia iteaphylla (medium shrub) Atriplex nummularia (small shrub) Atriplex amnicola (Prostrate Shrub) Cytisus palmensis (medium shrub/small tree) 450mm - 600mm Rainfall (between drip/leeaky hose irrigated/broadacre unirrigated fruit/tree crops etc.) Acacia retinodes (medium shrub - great edible seed yields esp. with varietal selection 1-1.5+ tonnes/ha @ yr. 5) Cytisus palmensis (medium shrub/small tree) Atriplex nummularia (small shrub) Atriplex amnicola (Prostrate Shrub) Casuarina cunninghamiana (tall tree - coppiced as multi-stemmed/suckering shrub) I once toyed with the idea of using Mesquite after reading J.Russell Smith's Tree Crops: A Permanent Agriculture, but then found that this was listed as an "economic plant" by virtue of its Noxious Weed status, and are therefore unable to utilise what appears to be an excellent species. With respect to the integration of leguminous species with Eucalypt forestry we have been successful in using the following species combinations (I can't list all combinations/species - just off the top of my head!) on both small and large projects. All are timber species with multiple low to high end use values. 250mm - 450mm Rainfall [835 spha (4m x 3m) with 70-80% thinned to final stocking rate - then harvested selectively as multispecies, managed permanent forest - no clear felling here!!] Eucalyptus cladocalyx Eucalyptus occidentalis Eucalyptus sideroxylon/tricarpa Eucalyptus camaldulensis Eucalyptus leucoxylon with Casuarina cristata Acacia pendula Acacia oswaldii Acacia stenophylla Acacia aneura Acacia salicina Acacia implexa 450mm - 650mm Rainfall [835 spha (4m x 3m) / 1000 sph (4m x 2.5m) / 1100 sph (3m x 3m) with 70-80% thinned to final stocking rate] Eucalyptus cladocalyx Eucalyptus botyroides Eucalyptus saligna Corymbia maculata Eucalyptus microcarpa Eucalyptus melliodora Eucalyptus occidentalis Eucalyptus sideroxylon/tricarpa Eucalyptus camaldulensis Eucalyptus leucoxylon Maclura pomifera Quercus lusitanica Quercus robur var. fastigiata Grevillea robusta with Allocasuarina leuhmanni Allocasuarina verticillata Robinia pseudoacacia Acacia pendula Acacia oswaldii Acacia stenophylla Acacia aneura Acacia salicina Acacia implexa Acacia dealbata Acacia melanoxylon Casuarina cunninghamiana Acacia mearnsii I hope that this helps you out, When our new web page is done you will have access to .pdf Fact Files (currenly huge files in MS Word) of all of the above and a lot more.
