Citation for the reference that describes the circumscription of the Element.
Since the circumscription of many taxa or communities may be described in the same reference, in order to uniquely identify the Element, the scientific name assigned to the Element in the concept reference is identified in the Name Used in Concept Reference field. The concept reference and the name used in that concept reference are fixed; thus, they provide a constant identifier for the Element, although the name in use for the Element and other associated data may change.
The purpose of using both the concept reference and the scientific name used in that reference as the unique and constant identifier of the Element is so that where different parties use different names for the same Element, the concept reference will allow clear determination that the entities are the same. Likewise, if different parties use the same name for different Elements, the concept references should quickly identify the entities as different.

Ecology & Life History
Delineation of populations or occurrences refers to the process of distinguishing discrete occurrences and representing them in a mapped form. Criteria for such delineations are developed from a rangewide perspective and used to promote standardization in how these occurrences or populations are defined and mapped at local levels. The primary intent of these standardized criteria is to ensure that occurrences are delineated such that: 1) for species they reflect populations or metapopulations whenever possible so that population viability can be meaningfully assessed; and (2) they are consistently defined and mapped.
Population/occurrence viability criteria provide guidelines for assessing the probability of persistence of an occurrence based on its size, condition, and landscape context. For species, probability of persistence is referred to as viability, whereas for ecological communities it is referred to as ecological integrity. Application of these criteria to an occurrence provides an assessment of the likelihood that, if current conditions prevail, the occurrence will persist for a period of time, typically 20-100 years depending on the species or community. Occurrence viability ranks are designed to be used in conjunction with species or community-level conservation status assessments to help prioritize occurrences for purposes of conservation planning or action, both locally and range-wide. The viability or ecological integrity of occurrences is also a factor in NatureServe's assessment of the overall conservation status for a particular species or community (see conservation status assessments).
U.S. Invasive Species Impact Rank (I-Rank)
Which non-native species pose the most serious threats to native species and ecosystems? To answer this question, NatureServe, in collaboration with The Nature Conservancy and the U.S. National Park Service, has developed a protocol for assessing and categorizing non-native plants according to their impacts on native biodiversity. The protocol is designed to focus specifically on the effects non-native species have on native plants, animals, and natural communities and to make the process of assessing non-native species objective, transparent, and systematic. It is intended to be applied to species as they occur over large areas, such as nations, ecoregions, provinces, or states.
The protocol is used to assess species individually for a specified region and to assign each an Invasive Species Impact Rank (I-Rank) of High, Medium, Low, or Insignificant to categorize its negative impact on natural biodiversity within that region. The protocol includes 20 questions grouped into four sections: Ecological Impact, Current Distribution and Abundance, Trend in Distribution and Abundance, and Management Difficulty. Each species is assessed by considering these questions, with the answers used to calculate a subrank for each of the four sections. An overall I-Rank is then calculated from the subranks. Text comments and citations to information sources are required to document the answers selected.
While designed for use in a specified contiguous, biogeographically diverse region, the protocol can be adapted to specified noncontiguous regions (such as the 50 U.S. states). NatureServe is now using the protocol to assess the non-native vascular plants that have established outside of cultivation in the United States. This dataform and scoresheet can aid in applying the protocol to other regions of interest.
