UK Biodiversity Indicators 2023. Indicator C9b: Plant genetic resources (Enrichment Index) 2023


This indicator was not updated in 2023. It was last updated in 2018.

These documents support indicator C9b – Plant genetic resources (Enrichment Index). The documents include a datasheet and technical background document.

As a result of discussions in the UK Plant Genetic Resources Group, a revised indicator is being considered; whilst development is underway it is not ready for publication.

Seed banks provide an insurance policy against the extinction of plants in the wild. They complement in situ conservation methods, which conserve plants and animals directly in the wild. The indicator is based on an enrichment Index developed by the United Nations Food and Agriculture Organisation (FAO 2010) to assess the genetic diversity held in gene banks. The method factors in duplication and similarity to existing accessions. An upward trending line indicates diversity is being added to collections – the steeper the line, the greater the diversity being incorporated. An accession is a collection of plant material from a particular location at a point in time.
