SNP, Criteria for admission

Admission to the section species of the National Plant Collection is subject to the
following criteria:

The plant collections comply with the first three objectives of the NPC:
- conservation and improvement of scientifically important living plant
  collections;
- conservation of valuable biodiversity;
- prevention of unnecessary duplication.
The plant collections can be placed under one or more of the following
headings:
- important addition to the NPC’s survey of the plant kingdom;
- ongoing or finalised scientific research (research or reference
  collections), preferably on taxonomic groups or geographically aligned collections;
  when very valuable;
- threatened plant species;
- collections of cultural or historical importance.
The long-term survival of the plant collections must be garanteed by the recipient institution, being admitted to the NPC might help Long term is currently considered to represent a time span of at least 10 years.
The plant collections are well documented, viz. recorded, catalogued, and
verified where possible. The garden maintains the necessary expertise,
documentation and literature on its specialisation.
- recording: the record system used can supply data as required by the DNPCF as advised by the NPC working group. In the plan period, ITF2 [the International Transfer Format of BGCI], will most likely be
  adopted.
- cataloguing: the data pertaining to accessions must be listed according to family and genus. Individual plants must be labeled with at least an accession number and where possible with the complete scientific name. In this case, ‘where possible’ means that when dealing with non flowering plants, identification may not have been possible as yet.
- verification: verification implies naming a plant correctly using
  taxonomic literature or by experts, either employed by the garden or externally. In addition, the name of the person responsible for the verification and/or the literature used must be recorded.
- expertise and literature: the presence of expertise beyond the average
  plant identification capability as well as an elaborate library on the taxon
  is essential for the quality of every specialisation maintained.
- documentation: the identity of accessions is consolidated by means of
  herbarium vouchers of that accession and/or images [photographs or
  drawings, either digital or as hard copy].
The plants are wherever possible of wild origin. For each plant, the source of supply must be given and data that pinpoint the original location in the wild must be recorded. This requirement is not applicable to cultivar collections, nor collections of historical nature or confiscated plants [in the latter case such data are either not available or not disclosed]. The source data [supplier information] must however be available.
The plant collections: each plant collection in general has a taxonomic
designation and in terms of size reflects the taxon covered by that
specialisation. It consist of at least several dozen accessions and may comprise
plants that are cultivated elsewhere.
Good reflection of the taxon is taken to mean a good representation of either alpha- [or species] diversity, or beta- [or genetic] diversity. These are referred to as 'in-breadth specialisation' and 'in-depth-specialisation' respectively:
- in-breadth-specialisation: constitutes a representative survey of the
  species of that taxon [family of genus] that can be cultivated
- in-depth-specialisation: for each [infra-] species as many provenances
  from the wild as possible from throughout the range of each [infra-]
  species, reflecting its genetic variation. In most cases the specialisation
  will cover a genus.
It should be noted that every specialisation is different and therefore percentages cannot be given. The Collections Committee decides for each specialisation whether the coverage of the in-breadth-specialisation or in-depth-specialisation is sufficient. Cultivar collections as generally considered to be in-breadth-specialisations. The minimum size required for a collection can vary considerably per collection. In case of large families such as Orchidaceae, Euphorbiaceae and Asteraceae, several dozen accessions are
insufficient for admission to the National Plant Collection. On the other hand small specialisations can be admitted when particularly significanct and if that garden already at least one other, larger specialisation already admitted to the NPC. The latter is for practical reasons. Examples of small sized collections of particular significance are Welwitschia and Ginkgo.
the plant collections are in principle available for education, research,
horticulture, environmental education, and biodiversity conservation [gene

Within the restrictions as imposed by the Biodiversity Convention, the plant collections must be accessible, although a fee can be charged to cover expenses. A willingness to exchange plant material is assumed.

	Criteria for the admission of collections to the Dutch National Plant Collection. The NPC currently comprises plants of the following groups: ferns and fern allies seed plants It is anticipated that eventually collections of the groups mentioned below will also become part of the National Plant Collection: Algae Lichens Mosses The NPC consists of two sections: the section 'species' the section 'cultivars' The criteria for admission into both sections are nearly identical. For practical reasons, the criteria are listed and explained under the section ‘species’. Where and when criteria differ for the section ‘cultivars’, this is mentioned explicitly in the text.
