Alnus jorullensis is a plant of tropical montane forests, where temperatures are cool, with abundant rainfall. They are also found in high-elevation, open, oak-pine and fir woodlands in Mexico[338 ]. Grows best in a sunny position, but is somewhat shade tolerant[310 ]. Prefers a heavy soil and a damp situation, but it succeeds in ordinary garden soil[11 ]. Grows well in heavy clay soils[11 ]. Tolerates very infertile sites[200 ]. The tree responds well to coppicing[303 ]. This species has a symbiotic relationship with certain soil micro-organisms, these form nodules on the roots of the plants 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 ]. Semi-deciduous in cool climates. In garden design, as well as the above-ground architecture of a plant, root structure considerations help in choosing plants that work together for their optimal soil requirements including nutrients and water. The root pattern is branching: a heart root, dividing from the crown into several primary roots going down and out [2-1].

Carbon Farming

• Agroforestry Services: Crop shade  Plants providing crop shade especially trees.
• Agroforestry Services: Nitrogen  Plants that contribute to nitrogen fixation include the legume family – Fabaceae.
• 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.
• Regional Crop  These crops have been domesticated and cultivated regionally but have not been adopted elsewhere and are typically not traded globally, Examples in this broad category include perennial cottons and many nuts and staple fruits.
