For centuries, human activity has intentionally or unintentionally driven the spread of plant species to areas far outside their native habitat. On average, about 10% of non-native species worldwide become invasive, often causing large ecological and economic consequences for affected regions.
Samoa has set her sights on planting three million trees, and possibly more, to protect the environment and fight back against the adverse impact of climate change. As of 2020, more than 2 million trees had been planted by school children, community based groups, N.G.Os, sports people and ot
The number of tree species on Earth
One of the most fundamental questions in ecology is how many species inhabit the Earth. However, due to massive logistical and financial challenges and taxonomic difficulties connected to the species concept definition, the global numbers of species, including those of important and well-studied life forms such as trees, still remain largely unknown. Here, based on global ground sourced data, we estimate the total tree species richness at global, continental, and biome levels.
Western Sydney University researchers have contributed to a world-first study that estimates there are 73,000 tree species on Earth, including about 9,200 species yet to be discovered, of which 1,500 species are likely to be concentrated in northeast Australia and the Pacific Islands.
Almost a third of the world’s tree species are at risk of extinction, while hundreds are on the brink of being wiped out, according to a new report.
If you're a tree, country life is much easier than city living. Rural trees—which can live long, productive lives of sometimes more than 100 years—draw on vast resources of an extensive forest network of nearby trees.
A University of Guam review of published research on the critically endangered Serianthes nelsonii tree has revealed a reason why the population of the trees continues to be endangered despite a long history of funded conservation projects and a national recovery plan implemented 26 year
Samoa has officially crossed the finish line in its Two Million Trees campaign, the Ministry of Natural Resources and Environment (M.N.R.E) has told the Samoa Observer. The campaign was designed to plant native and fruit trees from 2015 to 2020 to restore Samoa's forests after a decade of de
Tubi is a rare tree species found only in two provinces in the Solomons group: Isabel, where Korona is; and Choiseul, to the country’s west...For the people of Isabel, Tubi is a tree of significant value that holds a special place in their culture and belief system...Locals referred to it as the
