Habitat guilds experience land-use change
Part of: GS Prelims and GS -III – Environment
- A new study has noted a drastic loss of bird species in all modified landscapes in Uttarakhand.
- Natural oak-dominated forests and modified forests were analysed.
- Uttarakhand is home to the Western Himalayan temperate forests which harbour a large number of endemic bird species.
- Six major land-use types which included natural oak forest, degraded oak forest (lightly used), lopped oak forest (intensively used), pine forest, agricultural cultivation area and sites with buildings were studied.
- The results showed that there was a low diversity of species in monoculture areas and urban sites.
- It also noticed strong decline in some of the habitat guilds in the areas that experienced land-use change.
- Habitat guilds are groups of bird species that have common habitat preferences.
