Prefers a sandy loam and a very sunny position[1, 260], though it also succeeds in dry soils and is tolerant of wet conditions[260]. Succeeds in any good garden soil that is not excessively limey[11, 260]. Most species become chlorotic on limey soils[200]. Tolerates salt-laden winds and maritime exposure[200]. An extremely rugged tree, it grows rapidly, is adaptable to barren slopes, derelict land, and exceptionally arid conditions[269]. Reported from the Australian Centre of Diversity, orange wattle, or cvs thereof, is reported to tolerate alkalinity, drought, heavy soil, poor soil, salinity, salt spray, sand, shade, slope, waterlogging, and weeds[269]. Trees are not very hardy outdoors in Britain, they tolerate occasional temperatures down to between -5 and -10°c, but even in the mildest areas of the country they are likely to be killed in excessively harsh winters[11]. Plants spread by means of suckers[200] and trees that have been killed in cold weather can sometimes regrow from the roots. Regrowth of established bushes is so good that Acacia saligna can be completely grazed off without harming the plants[269]. Because of its hardiness and profuse reproductive abilities, Acacia saligna has become a serious menace in parts of South Africa by invading and displacing indigenous vegetation[269]. It infests water courses (sometimes decreasing the water available for irrigation), and has proved difficult to eradicate[269]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200]. It also has a symbiotic relationship with ants[200].

Carbon Farming

• Agroforestry Services: Nitrogen  Plants that contribute to nitrogen fixation include the legume family – Fabaceae.
• Agroforestry Services: Windbreak  Linear plantings of trees and shrubs designed to enhance crop production, protect people and livestock and benefit soil and water conservation.
• Fodder: Bank  Fodder banks are plantings of high-quality fodder species. Their goal is to maintain healthy productive animals. They can be utilized all year, but are designed to bridge the forage scarcity of annual dry seasons. Fodder bank plants are usually trees or shrubs, and often legumes. The relatively deep roots of these woody perennials allow them to reach soil nutrients and moisture not available to grasses and herbaceous plants.
• Fodder: Pod  Fodder plants with pods.
• Industrial Crop: Biomass  Three broad categories: bamboos, resprouting woody plants, and giant grasses. uses include: protein, materials (paper, building materials, fibers, biochar etc.), chemicals (biobased chemicals), energy - biofuels
• Industrial Crop: Gum  Used as thickeners and gelling agents. Non-destructively harvested gums come from tapped trees and seed.
• Industrial Crop: Tannin  Occur generally in the roots, wood, bark, leaves, and fruit of many plants. Used in tanning leather, dyeing fabric, making ink, and medical applications.
• Management: Coppice  Cut to the ground repeatedly - resprouting vigorously. Non-destructive management systems maintaining the soil organic carbon.
• Management: Standard  Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
• Minor Global Crop  These crops are already grown or traded around the world, but on a smaller scale than the global perennial staple and industrial crops, The annual value of a minor global crop is under $1 billion US. Examples include shea, carob, Brazil nuts and fibers such as ramie and sisal.
