How about creating a table, with one column listing the population ecology factors and the other (blank) column for program sustainability elements; submitting the table on this list. You would have to define the population ecology terms for us. Then list members could offer analogies. As list members offer suggestions the entire list could see the table being developed. In essence a modified Delphi technique and a unique use of this list. (Or if this would “clog up” the list, then it could be developed on your blog.)
Evaluation Uncertainty 
Hi Dave,
1) I like this idea but don’t have the cycles to make the table. If anyone wants to take a shot at it, go for it.
2) There is a hint of what you are suggesting in Odette Segal’s post. That might be a good place to start.
3) One hesitation I do have is the assumption that the mapping can in fact be done. That implies a commensurability across the two domains that I’m not sure exists. In fact, if it did exist, there would be no need to think of how PE could be applied at all. On the other hand, I can see a lot of value in seeing where there is overlap.
