Montana’s wolf  (Canis lupus) conservation and management plan is based on adaptive 
management principles and includes regulated public harvest as a population management 
tool. The need and opportunity to implement public harvest in 2008, 2009, and 2010 required 
Montana Fish, Wildlife and Parks (FWP) to develop a stepped down adaptive management 
framework specific to harvest. For 2008 and 2009, FWP set modest objectives: implement 
a harvest, maintain a recovered population, and begin the learning process to inform 
development of future hunting regulations and quotas. In 2010, FWP used a formal Structured 
Decision Making Process to more clearly define priorities and challenges of setting a wolf 
season, outline objectives of a successful season, and evaluate consequences and trade-offs 
between alternative management actions. For all years, FWP used a modeling process to 
simulate a wide range of harvest rates across three harvest units and to predict harvest effects 
on the minimum number of wolves, packs and breeding pairs. Model inputs were derived 
from minimum wolf numbers observed in the field. Modeling allowed consideration of a 
range of harvest quotas, predicted outcomes, and risk that harvest could drive the population 
below federally-required minimums. It also facilitated explicit consideration of how well a 
particular quota achieved objectives and how to adapt future regulations and quotas. Legal 
challenges to federal delisting restricted implementation of the first fair chase hunting season 
to 2009. Montana’s wolf population is securely recovered, despite the dynamic political and 
legal environments. Regardless, FWP remains committed to a scientific, data-driven approach 
to adaptive management.
