▁not ▁greatly ▁improve ▁the ▁out look ▁of ▁the ▁species . ▁The ▁optimal ▁distance ▁between ▁release ▁sites ▁was ▁determined ▁to ▁be ▁about ▁ 1 1   km , ▁allowing ▁the ▁sites ▁to ▁be ▁separated ▁enough ▁to ▁reduce ▁in tras pec ific ▁competition ▁immediately ▁after ▁release , ▁yet ▁close ▁enough ▁to ▁allow ▁the ▁sub pop ulations ▁to ▁merge ▁once ▁they ▁had ▁begun ▁to ▁pro l ifer ate . ▁ ▁Re pe ated ▁releases ▁Re pe ated ▁releases ▁in ▁the ▁same ▁area ▁have ▁affected ▁re int roduction ▁success . ▁The ▁first ▁group ▁of ▁Pers ian ▁fall ow ▁de er ▁released ▁into ▁the ▁wild ▁displayed ▁a ▁slow , ▁grad ual ▁movement ▁away ▁from ▁the ▁release ▁site ▁over ▁relatively ▁short ▁distances ▁and ▁the ▁establishment ▁of ▁regular ▁movement ▁patterns ▁and ▁a ▁home ▁range ▁within ▁ 8 ▁to ▁ 1 0 ▁months . ▁Sub sequ ent ▁releases ▁indicated ▁an ▁establishment ▁of ▁a ▁home ▁range ▁in ▁less ▁than ▁one ▁month . ▁Over all ▁rec ruit ment ▁success ▁after ▁ 3 ▁years ▁appears ▁to ▁be ▁at ▁least ▁ 3 0 %. ▁Moreover , ▁with ▁an ▁exception ▁of ▁a ▁small ▁number ▁of ▁females ▁killed ▁by ▁domestic ▁dogs , ▁the ▁surv ival ▁of ▁the ▁re int rodu ced ▁de er ▁was ▁high , ▁having ▁an ▁ 8 5 % ▁surv ival ▁rate ▁after ▁re int roduction . ▁These ▁results ▁indicate ▁that ▁repeated ▁releases ▁from ▁a ▁single ▁en closure ▁have ▁no ▁det r iment al ▁effects ▁and ▁actually ▁may ▁enh ance ▁the ▁establishment ▁of ▁females ▁released ▁in ▁later ▁re int roduction ▁events . ▁ ▁Time
