Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Birds play a pivotal role in ecosystems, but in disturbed areas their role may be limited due to the changes of their natural habitat. This paper studies the birds habitat in Simalungun and Asahan districts, North Sumatera. The study was conducted in four habitats: natural forest, rubber agroforests (RAF), rubber monoculture plantations (RMP) and emplacement areas (EA). The birds were observed using descriptive survey methods by implementing a quick biodiversity survey, data were collected along one km transect.  The results showed that in total, 142 species of birds from 42 families were observed in the four habitats. Natural forests had the highest diversity of bird species, followed by rubber agroforests, emplacement areas and rubber plantations, with a Shannon-Wiener index of 3.8, 3.6, 3.0 and 2.5, respectively.
