Plant Species on Transects
The database Plant Species on Transects available below for download provides the genus, specific epithet, and authority names for all taxa identified doing measurements on the Ongoing Vegetation and Exclosure Transects at the SRER. In addition, a translation of the species codes used in those databases and a synonymy table to assist in understanding scientific name changes are provided.
A total of 87 plant species and 29 species grouped by genera are included in the transect plant species database. Perennial species dominate the list because researchers placed less emphasis on annual species, especially during measurements performed in winter and early spring. Tree, shrub, and grass identification is reliable during any season, although difficulties in distinguishing some species led to the lumping of species into a single generic group. The lumping of threeawn grass species into an Aristida group is the best example of this practice. This list does not represent a flora for the SRER because annual species were not always recorded, and the measurements of vegetation for the ecological studies were restricted to relatively small plots (for example, 1 foot by 100 feet). The most recent and complete inventory of plant species of the SRER is available at Flora.
