Resource managers are often faced with making deci- <br />sions about dynamic ecological systems with signifi- <br />cant uncertainty about what the outcome will be of <br />implementing management actions. Management <br />decisions often include multiple or competing objec- <br />tives, predictions of system response, risk analysis, <br />identification of alternative actions, and uncertainty. <br />Adaptive management offers a structured and disci- <br />plined approach to these complex wildlife manage- <br />ment decisions. This approach to managing natural <br />resources can be traced back to the work of Holling <br />(1978) and Walters (1986), but is rarely implement- <br />ed under the operational definition provided by the <br />DOI technical guide: <br />'YO/N1 "'W" l! r7 a d-ci. zoft pro(,,­ rhal',' <br />p ro,-(nw, ­� r / "r h i </ft r/n, /zlft r /rr,r' (aft <br />ire the /f,(,,­ of / f c crlf,lftli,rr f, ou/c </; -(,/" fr</rn <br />rilC�fir� "rlt °f!! ac /IM / //M1 whcr w "fl! l rGo,ll" l rt °/ r <br />zm do !'ood t .f,! °c -�zr/ ;!/artlr <lrlft <!�r /rr,r <lzrrr <l;rz�s <br />�,<lll adl,)afa " cl"frll/n: z, d-r, , �// / hclp <br />61611Zl !
