yes, & im in that thread... 
So,anti hunting sentiment on behalf of preventing endangerment?  interesting,considering the permit fees,donations and taxes(In other words,Investments) paid by North American hunters/hunting organizations are exactly what helped bring some game species back from the brink of endangerment to the success story we enjoy today. 
Wildlife populations as a whole do very well when sportsmen/women invest time & $$ in a sound,biologically(not emotionally) based wildlife / land management system.  
Now,im NOT suggesting we start a sasquatch season,but if a similiar management system were implemented,id propose an optional donation when hunting licenses are purchased, sort of a"check here to donate $X amount to sasquatch program" kind of deal. 
give outdoorsmen a chance to get involved/interested you may be suprised by a potential recurring revenue directed towards proving/managing sasquatch & financing a squatch program as mentioned in the OP
