Planting trees is an essential solution to protect biodiversity and fight climate change. However, the process is surprisingly complex. Good trees need to be planted in the right place, otherwise it can do more harm than food. Bring deforested areas back to life – plant trees in areas that were once forested. Do not alter other natural habitats such as grasslands or wetlands. From seed collection to tree planting, it is important to use appropriate infrastructure and seed supply chains, preferably local. (6) Select species to maximize biodiversity: When planting, use a mix of species while prioritizing native plants that promote mutual interactions and exclude invasive species. The authors found several examples of successful tree planting programs focused on the local population, including a community-based forest management project in Nepal, a system called “ngitili” in Tanzania that uses traditional local knowledge to support collective land management, and a community-led reforestation project using local indigenous species in eastern Madagascar. where community members worked together to restore areas degraded by fire and overexploitation. The rules show how reforestation is more complex than many think.
Large-scale reforestation can improve global ecology and help prevent climate change, but these long-term benefits only occur when they rely on sound science and the support of local communities. Natural tree regrowth can be cheaper and more effective than planting trees. Experts at the Royal Botanic Gardens, Kew say tree planting is a brilliant solution to tackling climate change and protecting biodiversity. However, the wrong tree in the wrong place can do more harm than good. In Figure 2 above, a horizontal two-by-two is screwed or nailed into two vertical screws two by two placed on the side of the root ball and driven through the planting hole into the native undisturbed soil. A second set is used on the other side when necessary for larger trees. In Figure 3 above, two or three wooden pegs are driven through the edge of the root ball. These do not need to be removed, as they simply rot on the spot.
There is no danger that this system surrounds the trunk because nothing is attached to the trunk. These two low-cost alternative systems eliminate the need to return to the tree to remove the staking system, as they simply disintegrate within a few years. Long-term restoration of native forests and restoration of what existed before is much better at restoring biodiversity than simply planting fast-growing cultivated trees. The sustainability of tree planting depends on a source of income for all stakeholders, including the poorest. Integrate tree planting into the local economy so that people and communities can thrive with the forest. 4. Dig a real hole. Make the hole deep enough so that the tree is slightly above the nursery level. Plant the tree on solid soil, do not fill the dirt. In other words, do not dig the hole too deep, and then add soil to the hole before placing the tree. The root torch (the point where the trunk and roots meet) must be visible.
If not, remove enough soil or medium for this to be the case. The width of the planting hole is very important. It should be three times wider than the root ball. Loosening the soil outside the hole so that it is five times the diameter of the root ball will allow the tree to spread its roots faster. But when people plant the wrong trees in the wrong place, it can do more harm than good. It is advisable to conduct small trials before applying large-scale techniques to ensure that the right trees are used and to test their effectiveness. Let`s dive a little deeper into our ten golden rules of tree planting. The best planning decisions for tree planting are made when scientific results are combined with indigenous knowledge, the authors advise. The traditional knowledge gained over many generations of people who have lived near the forest is incredibly useful, while field experiments conducted by scientists, while also important, can take a long time to produce results. Science can be used to provide more specific information to support species selection, for example, taking into account the ability of certain species to withstand future climate change and to breed species that may never have been cultivated before, where producing viable seedlings can be a practical challenge.
