Montane bamboo is of very importance to the indigenous people inhabiting mountains of the Himalayas, and is a necessary component of highaltitude temperate forest ecosystems. Particularly, in Laya it is commonly used for weaving conical hat and other implements. Thamnocal amusspathiflorus (Trin.) Munro bamboo was documented as a main element of the conical hat making, displaying the highest altitude frost hardy bamboos in mixed coniferous forest. The cluster analysis specified major habitat of 60% significance (p-value ≤ 0.72) indicating a strong influence of bamboo density with associated species composition and other ecological factors. Unregulated harvesting of young culms and the harvesters repeatedly congregating in the same site resulted in unhealthy clump. Its narrow distribution pattern might threaten to population decline or total wipe off and also remote cause possibly by the spread of secondary forest tree species such as Picea spinulosa & Abies dens a that have gradually taken over areas previously occupied by the bamboo forest. Seventy percent of Laya pinter viewed agreed with the decline inthe production and use of conical hats. The element of this unique culture is under constant threat, for it was challenged by various factors including the stereotypical believes of the people.
