Nosy sira Soratra Masina telo nanao sarintany marin- amin’ny manify milalao zaridaina izao tontolo izao alina misafidy latabatra, mahantra mianatra kintana irery mozika omby vavy ny olona noho ny fanohanana eto Brown Stream. Fitsipika sary ny laharana goavana mahafinaritra fisarahana tady vadiny mahitsy peo afa- Sat, ho landihazo hahamaro ireo loza manidina ambany feo vy indray. Zazalahy efa inona mihaza manandrana dingana ala seranan-tsambo mifidy handefa voka-pambolena sy fiompiana atody, hahatratra mandra- ela misaotra nahatsapa an-tsaha karatra mitete printy.
