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

Range

Found in China. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Chittagong Croton

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Bamboo bear

ジャイアントパンダ（Ailuropoda melanoleuca）は中国中部の山岳竹林に生息し、体重最大125キログラムになるクマ科の動物で、食肉目に分類されながら食事の99%を竹が占める特異な食性を持つ。偽の親指（橈側種子骨）を使って竹の茎を把握し、1日14時間もの採食時間を費やす。2016年にIUCNレッドリストで絶滅危惧から危急（VU）へ改善されており、保護繁殖プログラムと自然保護区の設置が個体数回復に貢献している。

Chittagong Croton

The Chittagong Croton (Croton chittagongensis) is a Critically Endangered plant species in the family Euphorbiaceae, named for the Chittagong region of southeastern Bangladesh where it was first documented. The genus Croton is one of the largest in flowering plants, containing over 1,200 species of trees, shrubs, and herbs distributed across tropical and subtropical regions worldwide. Members typically produce alternate leaves that are often covered in stellate (star-shaped) hairs, and small unisexual flowers arranged in racemes or spikes. Like many Croton species, C. chittagongensis may produce aromatic oils or latex in its tissues. The critically endangered status of this species reflects the catastrophic scale of deforestation in the Chittagong Hill Tracts and surrounding lowland forests of Bangladesh, where remaining natural forest cover has been severely fragmented. The Chittagong region historically supported rich mixed-deciduous and semi-evergreen forest, but decades of agricultural expansion, fuelwood extraction, and urban growth have reduced forest extent dramatically. With an extremely restricted known range and severely degraded habitat, this species faces genuine risk of extinction without targeted conservation intervention. Formal population surveys, ex situ seed banking, and habitat protection or restoration efforts within the remaining forests of the Chittagong Hill Tracts and adjacent Myanmar border areas are urgently needed.
