Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Botswana, Iran, Kenya, Namibia, and Tanzania. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Christmas Fern

Habitat

Typically found in moist, shaded forest floors and tropical canopies.

Range

Distributed across Belgium, Canada, and United States.

Cheetah

地球上で最も速い陸上動物で、アフリカとイランの草原において短距離走で時速112kmに達する。深い胸部、長い脚、独特の黒い涙縞模様を持つ細身の体型が特徴だ。他の大型ネコ科動物とは異なり、チーターはチャープ音やパー音で鳴く。生息地の分断と大型捕食者との競争により、残存個体数は約7,000頭のみとなっており、危急種に分類されている。

Christmas Fern

The Christmas fern (Polystichum acrostichoides) is a robust, evergreen fern in the family Dryopteridaceae, native to eastern North America from Nova Scotia south to Florida and west to Kansas and Nebraska. It is one of the most common and widely recognized ferns in eastern North American forests, frequently encountered in deciduous and mixed woodland understories, shaded stream banks, rocky slopes, and ravine walls. The common name refers to the fact that the dark green fronds remain green through the winter, including the Christmas holiday season, making them a traditional decoration in some areas. The stipe and rachis are covered in brown scales, and the pinnae have a distinctive ear-like auricle at their base pointing toward the frond tip. Like other Polystichum species, the Christmas fern produces dimorphic fronds: sterile fronds with broad pinnae and fertile fronds with narrower, spore-bearing pinnae toward the tip. The species forms clumps that can persist for decades in suitable habitat. It is tolerant of shade and a variety of soil conditions, though it prefers moist, well-drained soils rich in organic matter. The Christmas fern is commonly used in native plant landscaping and is considered secure in conservation terms throughout its range.
