Pennantia baylisiana is considered to be only one tree in the wild. It's located at one of the Three Kinds Islands, off the coast of New Zealand.
St. Helena Gumwood
This tree is located in the South Atlantic and is one of the fourteen threatened species on the planet. The tree is known to be very useful in the wood craft industry, and in the use of timber for fuel. It is now St. Helena's official tree and is used very little for commercial purposes due to its rarity. Some pepole in St. Helena are building plantations in the hopes of creating more trees and have more supplies available to the crafting industry.
Honduras Rosewood
This tree is located in Belize, in Central America and it is confined to the most southern section of the country.
It is found almost exclusively along the rivers and in damp areas.
This tree is considered rare and is on the verge of endangerment. The reason for this is that it is one of the hardest woods out there, and it's primarily used for the manufacture of musical instruments.
As a result, more trees are falling for production than are being replaced.
Bois dentelle
This beautiful, delicate tree is exceedingly rare : there are only two Bois dentelle trees that remain in existence. The pair is located in the cloud forest of Mauritius. Though it has no commercial value, this species is near extinction because the cloud forest habitat has been severely damaged by alien invasive species. The Bois dentelle produces beautiful sprays of delicate hanging white flowers.
Florida torreya
This is a critically endangered conifer endemic to the Apalachicola River drainage of the Florida panhandle and adjacent southern Georgia. It has experienced a significant die-off and subsequent decline during the past century. Scientists believe that the most likely reason for the decline is fungal disease.
It is estimated there were 600,000 Torreya trees during the early 1800s. Only around 200 survive today.
Trees of Bambi
Trees of Bambi are Arrayan trees (Luma apiculata). They occur naturally only in very small areas of Patagonia and are one of the very rarest trees on earth. Disney animators on vacation found these amazing slow growing trees inspirational when they created the movie "Bambi."
Kauri tree [Agathis australis]
Kauri are among the world's mightiest trees, growing to more than 50 metres tall, with trunk girths of up to 16 metres and living for more than 2000 years. Kauri forests once covered 1.2 million hectares of New Zealand and were common when the first people arrived around 1000 years ago. Today they are declared "conservation dependent" by the IUCN. Waipoua is home to Tane Mahuta, king of the forest and the largest remaining kauri tree in the country. The 1500 year old Tane Mahuta is 51.5 metres tall, with a girth of 13.77 metres. The second and third largest kauri trees can also be found in the Waipoua Forest: Te Matua Ngahere and the McGregor Kauri. The forests of Waipoua are also vitally important refuges for threatened wildlife.
Baobab is the common name of a genus (Adansonia) containing eight species of trees, native to Madagascar (having six species), mainland Africa and Australia (one species in each).This tree is the National Tree of Madagascar.

The Baobab Tree is also known as the tree of life, with good reason. It can provide shelter, clothing, food, and water for the animal and human inhabitants of the African Savannah regions. The fruit, called "monkey bread", is edible, and full in Vitamin C
