Partitioning of Forest
Steppe sample sites using
hierarchical clustering.
Cluster numbers can be
increased or decreased
to study the different
levels of plant community
variation within a region.

Documenting and explaining plant community variation using systematic approaches is fundamental to the assessment of land
condition and devising sustainable land use practices and policies. This poster presents a statistical approach to characterizing
prominent plant community variations within eight natural zones of Mongolia. Hierarchical cluster analysis was used to group
ecological inventory sites sharing certain vegetation features, and summary statistics were calculated to determine the plant species
most characteristic or diagnostic of each cluster. Each panel below includes a scatter plot showing the cluster membership of
sample sites and their distribution along principal coordinates analysis (PCO) axes 1 and 2. Sample sites located close together on the
PCO scatter plot can be interpreted as having relatively similar vegetation characteristics. Site dissimilarity was computed using the
Bray-Curtis metric, and Ward’s method was used to cluster sites through agglomeration. Each panel also includes a table reporting
plant species frequency (first number in each column) and mean foliar cover (in parentheses) within individual clusters. In this case,
frequency is defined as the percentage of sample sites supporting a particular species, and mean cover reflects only those sites
having greater than zero cover. Species listed here are those having more than 50% frequency in at least one cluster. The next step is
to interpret plant community groups according to ecological potential and restoration needs.
