Management (Response Matrix Y) Ecological Status* Conditions of habitat of a plant species, whether wild, weed or ruderal or domesticated
Management types* Conditions of a plant’s management, whether gathered, tolerated, promoted, protected or cultivated
Management Systems* Spatial systems where a plant is found, ranging from natural vegetation to intensive cultivation
Number of Uses Sum of uses for each species, plus edible use, such as medicinal, forage, ornamental, etc.
Ecological (Matrix X) Spatial distribution Spatial availability or number of plots where a species was present on 98 plots (Table 2)
  Presence in one o more of six vegetation types grouped by Valiente-Banuet et al. 2000 [36].
Temporal distribution Temporal availability of the months than edible plants presents at markets.
Used Part Index Plant used index (based on Pieroni 2001 [58].
Life cycle Annual or perennial
Socioeconomic (Matrix W) Number of markets Market presence, between 6 markets and 1 market
  Number of stalls Average market stall were species plant is present
  Average price Average price of a plant species in all markets
  Sales Volume Total sales volume for a day in all markets
  Interchanged ways Transaction realized by barter and/or money or just by maize.
  1. * These variables were recategorized and were considered as another variable because some plant species had more than one value in this category. Values were summed in the recategorized variables.
