根据实地观察和来自瓦加杜古大学植物标本馆(OUA)和森肯伯吉安植物标本馆(FR)的标本数据，绘制了布基纳法索的植物物种多样性地图。一张收集强度和实地观察的地图显示了布基纳法索的植物学研究活动中心。为了克服与取样强度偏差有关的问题，对物种的分布进行了建模，并根据选定的四个科(禾本科、莎草科、山药科和茜草科)的维管植物多样性、生活型和多样性图进行了外推。最密集的采集和观测区域是Gorom-Gorom和Fada N‘Gourma周围。模拟的多样性一般向南增加，高位芽植物、藤本植物和半地面芽植物的比例也增加，而温生植物的趋势则相反。禾本科植物多样性与维管束植物总多样性高度相关，特别适合作为植物多样性的指标。莎草科在全国分布比较均匀，薯纵科仅分布于苏丹地带。茜草科植物在最南端的多样性最高。
A map of plant species diversity in Burkina Faso is presented based on field observations and specimen data from the Ouagadougou University Herbarium (OUA) and the Herbarium Senckenbergianum (FR). A map of collecting intensity and field observations illustrates centres of botanical research activities in Burkina Faso. To overcome problems associated with biased sampling intensity, distributions of species have been modelled and extrapolated to maps of vascular plant diversity, life forms and diversity of four selected families (Poaceae, Cyperaceae, Dioscoreaceae and Rubiaceae). The area of most intensive collection and observation is around Gorom‐Gorom and Fada N’Gourma. Modelled diversity generally increases towards the south, as does the proportion of phanerophytes, lianas and hemicryptophytes, while the opposite trend is observed for therophytes. Poaceae diversity is highly correlated with total vascular plant diversity, making the family especially suitable as an indicator for overall plant diversity. Cyperaceae are rather evenly distributed throughout the country, Dioscoreaceae are restricted to the Sudanian Zone. Rubiaceae have their highest diversities in the very south.
