Item’s groups



Use categories

Medicinal, food, handicraft, construction, fodder, dye, magic, fuel, veterinary, cosmetic

Use value

\(UVs = \sum {UV_{{is}} } {\raise0.7ex\hbox{${{\text{x}}^{1} }$} \!\mathord{\left/ {\vphantom {{{\text{x}}^{1} } {N_{s} }}}\right.\kern-\nulldelimiterspace} \!\lower0.7ex\hbox{${N_{s} }$}}\)

UVis: the use value of the species s for an informant i and Ns the total number of persons interviewed for the species s

\(UV_{{is}} = \sum {U_{{is}} } {\raise0.7ex\hbox{${{\text{x}}^{1} }$} \!\mathord{\left/ {\vphantom {{{\text{x}}^{1} } {N_{s} }}}\right.\kern-\nulldelimiterspace} \!\lower0.7ex\hbox{${N_{s} }$}}\)

Ui: the number of uses mentioned by each informant for species, n: the total number of informants. [44]

Organs exploited

Rootstock, root bark, leaf, stem, stem's bark, fruit, fibber, flower, seed

Index value of organ (IVO)

\(IVO = \sum {N_{{ui}} } {\raise0.7ex\hbox{${{\text{x}}^{1} }$} \!\mathord{\left/ {\vphantom {{{\text{x}}^{1} } {N_{{tu}} }}}\right.\kern-\nulldelimiterspace} \!\lower0.7ex\hbox{${N_{{tu}} }$}}\)

Nui: the number of use patterns of each organ quoted by informants i and Ntu the total number of uses of all organs quoted by the informants N. [45]

Commercial value


Index of commercial value (ICV)

\(ICV = I_{p} /I \times 100\%\)

Ip: the number of informants answering positively to sell the species plant parts and I: the total number of informants questioned (adapted from Lozano et al. [13])

Species abundance


Density (Ni)

\(Ni = n_{i} /S\)

Ni, the abundance in the plot i; ni, the number of individuals in the plot i,and S the area (1 ha)

Species dynamic

Increase, decrease, stable

Citation frequency (FC)

\(FC = N_{p} /N_{t} x100\%\)

Np: the number of times a particular response was mentioned and Nt: the total number of informants questioned (adapted from Faruque et al. [46])

Harvesting modes

Axe, hoe, machete


Conservation management practices

Seeding, assisted natural regeneration, partial harvest, fallowing areas, weeding protection
