AB  - The utilitarian redundancy model (URM) is one of the recent contributions to 
      ethnobiology. We argue that URM can be applied to access use-pressure on plant 
      species, the resilience of socioecological systems (e.g., local medical systems), 
      cultural keystone species, and the role of exotic species in social-ecological 
      systems. Based on previous URM studies, we also emphasize the need to differ 
      practical (considering plants and uses that are currently employed) and 
      theoretical (considering both currently employed and potentially employed plants 
      and uses) redundancy. Based on the main applications of the URM, we propose a new 
      index to access redundancy of a therapeutic indication: the Uredit, so that 
      Uredit = NSp + CR, were Uredit is the Utilitarian Redundancy Index for the 
      therapeutic indication; NSp is the total number of species mentioned for the 
      indication, and CR is the species' contribution to redundancy (in terms of 
      knowledge sharing). The maximum value that the Uredit could reach is twice the 
      number of species employed for the therapeutic indication. We believe that this 
      theoretical and methodological improvement in the model can improve comparisons 
      of redundancy in different social-ecological systems. We also highlight some 
      limitations of the URM (and our Uredit), and we believe that conscious reasons 
      behind people's decisions should be incorporated into future studies on the 
      subject.
