Summary 2007 Collected 547 samples. Genotyped 328 (67% ) Identified 210 individuals Multiple samples for 31 bear (15%)
Capture - recapture Problem em too few recaptur ptures es – tot otal al 31 of of 210. Should be 2.5 to 3 times more samples than the estimated population size. We had less than 1/3. Therefore big margine of error (SD=22). Obtained values were: Gorski kotar N 133 Gorski kotar S 150 Velebit 136 TOTAL 419 Extrapolation to the whole bear range: Possible 1000 bears s in the whole e range.
