The Dragon's Blood tree.
這是龍血樹
The key to their success lies in their bizarre shape.
龍血樹成功的關鍵 在于它們奇特的形狀
They live on the mountain tops where there's little soil,
它們生長在土壤不多的山頂上
but there are critical compensations.
但山頂有很重要的好處
Occasional morning mists sweep across the high ground.
這里偶爾會飄過晨霧
The mist condenses on the skyward-pointing waxy leaves.
霧氣在朝天的 蠟質樹葉上凝結成水
The droplets run down to the centre of the trunk
水滴沿著樹干
and down to its roots.
流到根部
Water is so precious that the tree cannot afford to waste any.
這里的水分太珍貴 一丁點都不能浪費
Drops that do escape and fall to the ground are not totally lost.
水滴到地上也不打緊
The tree's huge, densely packed crown acts as a parasol.
龍血樹巨大濃密的樹冠像把陽傘
It shades the ground so effectively
有效地遮住陽光
it allows time for the water to seep into the sand.
讓水分有時間滲入沙地
And it also shades the network of roots that lie just under the surface.
同時也護住位于地表淺層的根部
Another plant shares this parched desert, but survives in a very different way.
這片干熱沙漠還有另一種 生存策略很不一樣的植物
