Road ecology blog: Canopy crossings for brown howler monkeys, Rio Grande do Sul, Brazil.
Through the Urban Monkeys Program, power lines were insulated and six canopy crossings were installed in a neighborhood adjacent to the Lami José Lutzenberger Biological Reserve. The aim of the program is to reduce electric hazards and road-kills for brown howler monkeys (Alouatta guariba clamitans). The power company insulated the power lines in several places, especially around the canopy crossings. The implementation and monitoring effort of the canopy crossings involved the local community. The following species have been observed using the structures: brown howler monkey (Alouatta guariba clamitans), white-eared opossum (Didelphis albiventris), and orange-spined hairy dwarf porcupine (Sphiggurus villosus).
The research was conducted by Fernanda Zimmermann Teixeira
and her colleagues at Universidade Federal do Rio Grande do Sul
. For more information see Fernanda Zimmermann Teixeira et al. 2013.
