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 ...
Climate change adaptation has garnered more importance in UNFCCC negotiations in the 2020s as opposed to older times, when mitigation was given more focus. Silvopasture systems which integrate trees and other woody plants along with crops, forage and livestock are a highly sustainable strategy that has huge adaptive capacity, besides its mitigation potential.
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.
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]
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 ...
The term allelopathy from the Greek-derived compounds allilon-(αλλήλων) and -pathy (πάθη) (meaning "mutual harm" or "suffering"), was first used in 1937 by the Austrian professor Hans Molisch in the book Der Einfluss einer Pflanze auf die andere - Allelopathie (The Effect of Plants on Each Other - Allelopathy) published in German.

Many animals obtain energy by eating the surrounding vegetation, however, desert plants are much more difficult for organisms to consume. [10] To avoid intense temperatures, the majority of small desert mammals are nocturnal, living in burrows to avoid the intense desert sun during the daytime.
Some naturalised species, such as palms, can act as ecosystem engineers, by changing the habitat and creating new niches that can sometimes have positive effects on an ecosystem. Potential and/or perceived positive impacts of naturalised species are less studied than potential and/or perceived negative impacts.
