Researchers from the South China Botanical Garden of Chinese Academy of Sciences developed a species screening model to select more species that have comparable restoration abilities to the target species that have high survival rates for vegetation restoration. Based on a software platform developed by themselves, the researchers conducted their study in a tropical coral island of southern China's Hainan Province. Among the 66 species identified as high potential for restoring the island, the researchers identified and measured 28 traits that are strongly associated with harsh environments including drought, high temperatures, intensive UV radiation, lack of real soil and nutrients and high salinity and alkalinity. They transplanted seedlings of all 66 species to the island to monitor the seedlings survival and found that 12 species had high survival rates ranging from 86 percent to 91 percent. The vegetation selection based on the research procedure can be finished within two months. Selecting suitable species for vegetation restoration was crucial for land managers and scientists. The researchers hope their work can be helpful for vegetation restoration in tropical islands, as well as other ecosystems.

Phosphorus is considered a crucial nutrient element for plant growth. Its undersupply may influence the productivity and carbon sequestration of natural terrestrial ecosystems and crop yield in farmlands. Phosphorus addition is an experimental approach, which can be used to judge whether plant growth is significantly limited by phosphorus supply. In a research article recently published in the journal Nature Communications, researchers from the South China Botanical Garden of the Chinese Academy of Sciences studied the global pattern of phosphorus limitation on plant growth in terrestrial ecosystems. They found that 46.2 percent of the 652 field experiments witnessed a significant promotion of plant growth by phosphorus additions. Globally, phosphorus additions increased aboveground plant production by 34.9 percent in natural terrestrial ecosystems and increased crop yield by 13.9 percent in farmlands, said the article. The research findings showed that phosphorus limitation of terrestrial plant growth is a worldwide phenomenon. “The results do not necessarily indicate the need for phosphorus fertilization in natural terrestrial ecosystems because excessive phosphorus fertilization may cause loss of biodiversity and eutrophication of water bodies,” said Hou Enqing, the lead author of the article. “Instead, we highlighted the critical role of phosphorus supply on terrestrial plant growth and call for more attention to phosphorus supply.”
