SUMMARY:

The effect of use interactions has been poorly studied, limiting our understanding of how a plant's importance for one purpose can protect it from other more destructive uses. Therefore, we tested the protection hypothesis, in which we assessed whether food uses protect woody plants from timber uses when the latter are more damaging. We tested the hypothesis from two perspectives (protective effect proportional to the species' food importance or protective effect only in key species). We conducted the study in a rural community located in Restinga vegetation in Northeast Brazil. Through a participatory workshop, we identified three key species (food species with high importance for consumption and income generation) and their respective occurrence/collection sites. We identified other species that co-occurred with the key species through a phytosociological inventory in three areas. We used field herbarium and photos of these species as visual stimuli during the checklist interview. Respondents evaluated the species based on wood quality, perceived availability, and use. To test the hypothesis, we performed CLMM and GLMM models. Overall, we did not find a protective effect proportional to the food importance of the species. However, we identified a strong protective effect directed towards the key species. Perceived availability and efficiency were significant explanatory variables for timber uses. We recommend biocultural conservation strategies that emphasize the food importance of plants to ensure their protection, as well as strategies focused on exclusively timber species, which may be under greater usage pressure.
