The analysis of the flora of North Dakota.

In 2011, we started the systematic investigation of the North Dakota flora with a priority to fill "botanical white spots". The sampling included choosing location, photographing, field labeling, geo-referencing, field and base pressing, restacking, determining, databasing and permanent labeling. Now most of the territory is covered with sampling of approximately 30 by 30 miles density. 3,100 herbarium samples were deposited into Minot State University herbarium collection (MISU). Sixteen new plant species were found in our state. Data collected in 2011-2012 allowed us to publish the first full list of North Dakota plants: The checklist source is a product of interactions between more than 40 species lists and 8 "filters" which add information to species names. Nomenclature problems were solved via programmatic normalization. More than 2,800 photographs made in the field were attached to plant names. Along with the Web service, there is the downloadable PDF book (ISBN 978-1-4675-6379-6). If new information will appear, both book and Web page will be updated simultaneously through scripts written for R language and TeX/LaTeX text formatting system. Flora of North Dakota consists of 1651 species, 665 genera and 121 families of vascular plants (plus 300 plant species without location). The state has typical north temperate grass- and wetland flora with a dominance of aster and grass families, sedges and legumes. The most frequently collected species are water knotweed, asters, horsetails and grasses. Among our counties, Ransom and Richland have the most diverse flora (more than 55% of state species), and Trail, Adams and Towner -- least diverse (less than 25%). North Dakota has 131 "local endemics", plants which do not occur in any neighboring state or province. There are also 43 species which were found in all surrounding territories (but not in our state). Proportion of plants common between our state and neighboring territories, is equal (proportion test X-squared = 24.35, df =3, p << 0.05). The cluster analysis of species composition revealed that our flora is most similar to the flora of South Dakota. However, our state has the biggest number of common unique plants (plants which grow only in two states) with Minnesota (41 species) and then with Montana (29) which probably indicate the current routes of plant distribution. All counties were compared by plant composition. We will also report distribution of introduced and invasive species.
