orang are proving more adaptable than look when it comes to get around , giving them a good opportunity of survival as their homeland are chip at up for logging .
Dr. Brent Loken placed 97 motion - triggered cameras in orangutan habitat in East Kalimantan , Borneo . The television camera were range in three case of areas : primary rainforestwith full ceiling canopy and complex understory , secondary forest recovering from damage , and recently logged areas .
In total , the photographic camera run for 28,485 days and night , and record 296 visits from the endangered species .

The behaviour of the great apes vary by the type of forest . In the log area , thePongo pygmaeus moriowere more inclined to use the ground to get around than to swing through the trees . There isan obvious explanationfor this : logged forests have less tree canopy to swing through . But inOryx , Loken concludes that this is not the whole story .
“ Orangutans were also planetary [ walk on the ground ] in primary forest , where there was a unopen canopy and ample opportunity for moving through the Sir Herbert Beerbohm Tree , ” Loken writes . While there were previous theme of grownup males choose leg over weapon as the preferred method acting of travel , Loken reports , “ male and female person , even females with baby , were register almost equally walk on logging roads , trail and ridges . "
“ Our answer signal that orang may be more terrestrial than previously thought and demonstrate opportunistic behavior when move through their environment , including using newly constructed logging road for locomotion , possibly indicating some degree of resiliency to human disturbance . ”
Loken is concerned his workplace may be misused , stressing , " We must be careful not to reinforce the notion that orangutang can survive in any man - neutered landscape . They still demand trees and wads of them , and the protection of Borneo ’s remaining forests should continue to be of the highest priority for Indonesia and the rest of the world . "
Nevertheless , the finding evoke that there may be mode to mix human activity in rainforests in ways that do not harm our close relative andfellow citizenry .
Loken is a former petty - schooltime dealer who give up educational activity to explore the ways both sustainable and environmentally damaging land - enjoyment practice affect local community . Three years ago , his workmade headlineswhen his cameraspicked up an imageof aMiller ’s grizzled langur , a type of rapscallion previously considered extinct .
