It is estimated that one in three tree species is at risk of extinction due to agriculture, grazing and animal husbandry, according to one report.
The Manai Knife, with only 30 trees grown in its North Wales home, is one of hundreds of endangered species, according to the first “Tree Condition” report.
Assessing the roaming of some 60,000 tree species worldwide, 30% or 17,500 are at risk of extinction, and the most popular species, such as magnolia, are endangered.
Oak, maple and ebony are endangered, according to a report published by Boknik Gardens International.
The study compiles international tree evaluation work over the past five years, examining the risk of extinction for more than 60 institutions and more than 500 professionals for 58,497 tree species.
One of the five tree species is used directly by humans for food, fuel, wood, medicine, horticulture, and other uses.
But despite the value of trees to humans, at least 142 species have been extinct due to over-exploitation and mismanagement, and many more have been lost.
The main threats are clearing for crops, logging and deforestation, the assessment warns.
Climate change is also a growing concern, as more trees become warmer and the climate changes, the Central American cloud species are particularly endangered.
There are at least 180 species of trees in the Caribbean, including magnolia, due to sea urchins and extreme weather, increasing the risk of fire in Madagascar and American oak.
The report warns that more than 440 species of trees remain in the wild, with only a few remaining on Mount Mulanje, including the Manai White Blaine and Mulanje Cedar in Malawi.
Islands have the highest risk of deforestation, with 69% of the trees on the island of St. Helena at risk of extinction, and 59% of those found in Madagascar.
In Europe, 58% of European trees are endangered in the wild, whites and rhubarb are endangered, and Brazil has the highest number of tree species.
“This report is an alarm to all around the world that trees need help.”
Dipterocarpaceae species are endangered from palm oil fields in Borneo, timber production in Madagascar Ebony, and mahogany and rhododendrons in the Caribbean and Brazil.
Magnolia and camellia species, which are used for sustainable commercial harvesting, pests and diseases, are causing a sharp decline in ash in the UK and North America, and oak has become a rarity in the forest, particularly in South and Central America, the report said.
The report highlights the need to care for trees, two-thirds (64%) of all tree species can be found in at least one protected area, and about 30% can be found in orchards, seed banks or other collections.
BGCA calls on governments and experts to extend the protection of endangered species, to protect all endangered trees in plant gardens and seed banks as much as possible, and to increase public and corporate funding.
In its report, the organization called for the expansion of tree planting plans – by planting endangered and indigenous species – and by increasing international cooperation to combat deforestation.
Paul Smith, BGCC Secretary-General, said: “This report is a wake-up call to all around the world that trees need help.
Every tree species is important – to millions of other tree-based species and to people around the world.
Thanks to the World Tree Report, we can pinpoint which tree species need our help, so policymakers and conservationists can deploy resources and skills to prevent future extinction.
“For the first time, the world’s trees are in a state of total decline,” said John Paul Rodriguez, chairman of the World Conservation Commission.
“Knowing where they are and why they are shocked is the first step in protecting them.
Despite the alarming data, I look forward to future world tree reports as I look forward to learning from the growing success of the planned breed and the declining risk of extinction. ”Integrated World Conservation Action.
