DOES THE SPATIAL PATTERN VARY?— Vanilla bahiana is an orchid restricted to Brazil, extremely ornamental, threatened with extinction and with economic potential. We evaluated the spatial distribution pattern of V. bahiana in shrub and restinga forest formations in a conservation unit in Northeast Brazil. The Morisita’s index of dispersion, the Morisita’s standardized index of dispersion and the TTLQV method were used, and 1920 m2 were sampled, through the demarcation of six transects of 40 × 4 m per phytophysionomy.
