Araucaria schmidii is a species of the genus Araucaria ( Araucaria ). It is endemic to theisland of Grande Terre, part of New Caledonia .
description
Araucaria schmidii grows as an evergreen tree that can reach heights of up to 30 meters. The ascending and feathery branches are 6 to 9 millimeters thick. The gray bark peels off in long strips that are 10 to 15 centimeters wide.
On young specimens, the thick leaves are scale-like and have a curved tip. They are lanceolate-keeled with a length of around 2 millimeters and a width of around 1.5 millimeters. On older specimens, the scaly leaves, which overlap like roof tiles, are 7 to 10 millimeters long and 1.5 to 2 millimeters wide and are lanceolate-keeled with a curved tip.
The male cones are about 5 inches long and 1.5 inches thick. The female cones reach a length of 9 to 11 centimeters and a diameter of 7 to 9 centimeters.
Occurrence
The natural range of Araucaria Schmidii includes the in the northeast of Grande Terre nearby Mount Panie . You can find them there in the summit region and on the higher mountain slopes. The entire distribution area covers an area of around one square kilometer.
Araucaria schmidii thrives at altitudes of 1500 to 1630 meters. It is the only araucaria species in New Caledonia that does not grow on ultra-basic rock . You can find them mainly in the cloud forest .
Systematics
Araucaria schmidii belongs to the section Eutacta within the genus of the Araucarias ( Araucaria ). It was first described as Araucaria schmidii in 1969 by David John de Laubenfels in Travaux du Laboratorie Forestier de Toulouse 1 (8) Art 5: p. 1.
Hazard and protection
Araucaria rulei is listed as "endangered" on the IUCN Red List . The total population is estimated to be less than 1000 fully grown trees. Due to the small distribution area and the small number of trees, the species is considered to be susceptible to capricious weather, as these can damage the entire population. Since Mount Panie is a popular destination for eco-tourists, there is also a risk that these diseases such as Phytophthora will be introduced into the population.
