Matrices	Variables	Description

	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.

* 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.
