全球約 30% 的樹種面臨滅絕風險 - 報告
總體而言，受威脅的樹種數量是受威脅的哺乳動物、鳥類、兩棲動物和爬行動物總和的兩倍。

根據植物園保護國際 (BGCI) 週三發布的具有里程碑意義的報告，世界上近三分之一的樹種面臨滅絕的危險，而數百種樹種瀕臨滅絕。
根據《世界樹木狀況》報告，17,500 種樹種（約佔總數的 30%）面臨滅絕風險，而 440 種樹種的野生數量不足 50 只。
報告稱，總體而言，受威脅的樹種數量是受威脅的哺乳動物、鳥類、兩棲動物和爬行動物總數的兩倍。
BGCI 秘書長保羅史密斯在一份聲明中說：“這份報告向世界各地的每個人敲響了警鐘，樹木需要幫助。”
風險最高的樹木包括木蘭和龍腦香等物種，它們在東南亞熱帶雨林中很常見。報告稱，橡樹、楓樹和烏木也面臨威脅。
樹木有助於支持自然生態系統，被認為對應對全球變暖和氣候變化至關重要。單一樹種的滅絕可能會導致許多其他樹種的消失。

“每種樹種都很重要——對依賴樹木的數百萬其他物種以及世界各地的人們來說，”史密斯補充道。
報告發現，世界樹種多樣性排名前六的國家的數千種樹木面臨滅絕的危險。最大的單一數字是在巴西，那裡有 1,788 個物種處於危險之中。
其他五個國家是印度尼西亞、馬來西亞、中國、哥倫比亞和委內瑞拉。
報告稱，樹種面臨的三大威脅是作物生產、木材採伐和畜牧業，而氣候變化和極端天氣是新出現的威脅。
報告稱，至少有 180 種樹種受到海平面上升和惡劣天氣的直接威脅，特別是加勒比地區的木蘭等島嶼物種。
儘管生物多樣性豐富的國家面臨滅絕風險的品種數量最多，但島嶼樹種面臨的風險更大。
報告補充說：“這尤其令人擔憂，因為許多島嶼都有其他地方找不到的樹種。”

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 landmark report published by Botanic Gardens Conservation International (BGCI) on Wednesday.
According to the State of the World's Trees report 17,500 tree species - some 30% of the total - are a risk of extinction, while 440 species have fewer than 50 individuals left in the wild.
Overall the number of threatened tree species is double the number of threatened mammals, birds, amphibians and reptiles combined, the report said.
"This report is a wake up call to everyone around the world that trees need help," BGCI Secretary General Paul Smith said in a statement.
Among the most at-risk trees are species including magnolias and dipterocarps - which are commonly found in Southeast Asian rainforests. Oak trees, maple trees and ebonies also face threats, the report said.
Trees help support the natural ecosystem and are considered vital for combating global warming and climate change. The extinction of a single tree species could prompt the loss of many others.

"Every tree species matters — to the millions of other species that depend on trees, and to people all over the world," Smith added.
