RECOMMENDATIONS
Short-term
r 1) Adopt N. as a mean IMO for each population (Table 7).
I2) Initiate a monitoring program for N? N and expand ISNT to include other species and
population estimates.
' 3) Review and update IMOs on a regular basis as new information becomes available.
4) Identify the populations required to meet down-fisting criteria.
5) Identify habitat improvement actions required to meet down-listing criteria.
Long-term
1) Obtain fife-stage information that would enhance the ability of the Crowl and Bouwes
(1998) life-stage model to predict demographic stochasticity. This information should be
attained by conducting the studies outlined in their model description document.
2) Develop long-term recovery objectives based on demographic model refinement.
