Terrestrial and Freshwater Invertebrate Red List Authority

The IUCN Red List currently contains only a very small proportion of invertebrates (21% of species on the list and <1% of described invertebrates assessed: see 'Spineless' the 2012 report on the status of invertebrates). The Red List now plays a major role in conservation planning and biodiversity research funding decisions, even though but the vertebrate bias seriously limits its reliability. There is a need to make the list more comprehensive and to ensure the current assessments are accurate.

Specialist Groups are working towards this end but cover only a tiny proportion of non-marine invertebrate groups, the remainder are the remit of the Terrestrial and Freshwater Invertebrate Red List Authority (TIRLA).

TIRLA is seeking to improve the Red List through two approaches: updating the old assessments and encouraging new assessments. Assessments from 1996 need updating and are known to contain several incorrect assessments which need changing, there are only a small number of species in this category.

TIRLA is also encouraging people interested in Red Listing of particular taxonomic groups to form Red List Group and start the process of preparing new assessments. These Red List Groups could cover families, orders or functional groups, and be global or regional in their scope.

The Red List process does not have to take long or be too difficult. Assessments can include a large amount of data but for most invertebrates available data are very limited. At a minimum we need: taxonomic name (and we can include notes that a 'species' may actually be a species complex needing revision), an estimate of probable distribution, habitat type and probable threats.
Anyone interested in assessing old assessments, reviewing new ones or setting up a Red List Group please contact the TIRLA coordinator Justin Gerlach at gerlachs@btinternet.com

Existing Red List Groups within TIRLA:

    European Saproxylic Beetle Red List Group
    Millipede and Centipede Red List Group
