Habitat degradation

According to Olson and Dinerstein (1998), most temperate freshwater biota are threatened by invasion of exotics, pollution, dams, and habitat degradation. 

Nr is responsible for eutrophication, hypoxia, loss of biodiversity, and habitat degradation in coastal ecosystems. Nr is now considered the biggest pollution problem in coastal waters (e.g., Howarth et al., 2000 NRC, 2000 Rabalais, 2002). 

The abundance of this naturally rare plant appears to be declining due to human collection for traditional uses, and habitat degradation (Shrestha, 2010). Himalayan Amchi Association (HAA) and a private herbal farm (Khamso Nature Product) have initiated to domesticate this plant in Mustang and Manang, respectively, in small scale (per. obs. of BBS). 

However, naturally rare and fragmented population, habitat degradation due to high grazing pressure, and collection of the plant before seed set warrant for the need of conservation of this important plant species.
