A paloverde tree acting as a nurse plant to a saguaro in the Sonoran Desert not far from the Superstition mountains. A nurse plant is one that serves the ecological role of helping seedlings establish themselves, and of protecting young plants from harsh conditions. This effect is particularly well studied among plant communities in xeric ...
A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
By contrast, tropical reforestation projects lead to a positive change such as the formation of clouds. These clouds then reflect the sunlight, lowering temperatures. [57]: 1457 Planting trees in tropical climates with wet seasons has another advantage. In such a setting, trees grow more quickly (fixing more carbon) because they can grow year ...
Many studies suggest termite mounds are regenerating desert soil and promoting plant growth in these environments. Part of this is due to the termite’s ability to terraform, stirring up nutrient ...
Thus, the nature of species interactions may shift with environmental conditions. Facilitation has a greater effect on plant interactions under environmental stress than competition. [9] Another example is the positive effects of facilitation on desert plants that face the effects of rising aridification.
It aims to plant 50 million trees. [111] Despite this, the UK government has been criticized for not achieving its tree planting goals. [112] [113] There have also been concerns of non-native tree planting disturbing the ecological integrity and processes of what would be a native habitat restoration. [114]
The Three-North Shelter Forest Program (or "Green Great Wall") is a Chinese government tree-planting project begun in 1978 and set to continue through 2050. The goal of the program is to reverse desertification by planting aspen and other fast-growing trees on some 36.5 million hectares across some 551 counties in 12 provinces of northern China.
A eucalyptus plantation in final stages at Arimalam.. The type of tree planted may have great influence on the environmental outcomes. It is often much more profitable to outside interests to plant fast-growing species, such as eucalyptus, casuarina or pine (e.g., Pinus radiata or Pinus caribaea), even though the environmental and biodiversity benefits of such monoculture plantations are not ...
