Global Inventory of Floras and Traits

GIFT is an initiative to create a database of regional plant checklists with complete global coverage for large-scale biogeographical and macroecological analyses based on plant species identities and regional species composition (Weigelt et al. 2020). To this end, GIFT includes regional plant species lists based on published and unpublished floras and checklists as well as online databases. At the level of individual plant species, GIFT contains functional traits as well as taxonomic and phylogenetic information. At the level of geographic regions, it additionally contains information on physical geographic, bioclimatic and socio-economic characteristics.

GIFT workflow

Regional Floras

For each geographic region, GIFT contains one or more species lists of a particular taxonomic group (e.g. vascular plants, angiosperms, or a plant family). The main focus of GIFT lies on species native to a given geographic region (e.g. islands, administrative units, protected areas). We therefore include information on the floristic status of the species (e.g. native, naturalized, endemic) if available in the literature resource. Data on naturalized alien species collected in the scope of GIFT is included in the Global Naturalized Alien Flora (GloNAF), a complementary initiative to map the global distribution of alien plant species naturalized outside their native ranges (van Kleunen et al. 2015).

The database started out as a global collection of island floras. It therefore offers a very comprehensive overview over the floristic composition of 2,282 of the world's islands. The collection of mainland floras is work in progress with up to now 1,345 mainland regions covered aiming at complete global coverage and increasingly high regional resolution. Please use the map interface to see for which combinations of geographic region, taxonomic group and floristic status species checklists are available.

Taxonomy and Phylogenies

Gift covers species from all major groups of land plants (Embryophyta). The main focus for the collection of species lists and traits, however, is vascular plants (Tracheophyta) and in particular angiosperms (Angiospermae). All species names enter the database in their original form including infraspecific name information and author names. In order to make species identities comparable across regions, species names are submitted to a semi-automated taxonomic standardization and validation procedure, since GIFT version 3.0 based on taxonomic information provided by the World Checklist of Vascular Plants (Goevarts et al. 2021) and iPlant’s Taxonomic Name Resolution Service. Genus names that do not occur in the World Checklist of Vascular Plants are corrected manually. Species counts per region, floristic status and taxonomic group presented on this website are based on the standardized species names and do not include infraspecific taxa.

All species are linked to a taxonomic backbone based on the Angiosperm Phylogeny Group (APG) IV system making it possible to extract regional species lists for certain taxonomic groups. In addition all angiosperm species are linked to phylogenies (e.g. Smith & Brown 2018) for phylogeographical analyses.

Plant Functional Traits

GIFT currently contains information on 109 functional traits covering important features related to plant morphology, life history, reproduction, physiology, and ecology. Each trait is defined either by a set of specified categorical values or a unit of measurement. Original trait information from floras, field measurements, or databases are manually standardized according to this scheme and imported into GIFT. We then apply a hierarchical derivation procedure that fills data gaps using available information in other traits (König et al. 2019). For example, woodiness status can be derived from growth form, growth form can usually be derived from life form, etc. Derived trait values are only retained when the concerned species does not have any original information for the respective trait. To eventually obtain a single, standardized value per trait and species, original and derived trait values are automatically aggregated based on the agreement of resources (for categorical variables) or the mean, minimum or maximum value of the original values (for numerical variables). Throughout the entire procedure, information can be traced back to their original reference and unstandardized value.

Environmental Characteristics

For each geographic region a suite of 217 physical geographic, bioclimatic and socio-economic characteristics is computed based on the spatial polygons assigned to the region and additional GIS resources. This includes (1) characteristics based on the regions’ polygon itself like its area, centroid coordinates and extent, (2) summary statistics derived from raster layers like digital elevation models, climate surfaces (e.g. CHELSA, Karger et al. 2017) or population density, and (3) miscellaneous metrics calculated from additional polygon resources like biogeographic region affinity or island isolation (Weigelt & Kreft 2013).

Data availability

Access

GIFT data is available via the GIFT R-package. Tutorials of how to yúse it can be found here.

A few data contributors of GIFT asked to restrict access to their data for now. These data can be accessed through the R-package specifying a password-protected API (provided upon request) and their use requires contacting the owners of the data and asking for permission to use them. Please contact us at gift[at]uni-goettingen.de if help is needed regarding the use of GIFT data.

Citation

Publications using the GIFT database should cite all primary references as well as the version of GIFT and the original publication of the GIFT database (Weigelt et al., 2020). All primary references in GIFT are available using the GIFT_references() function. If GIFT data are retrieved through the R-package, the package and its accompanying publication (Denelle et al., 2023) should also be cited.

Updated workflows include:

(1) New taxonomic name standardization based on WCVP.

(2) More statistics on species level trait aggregation.

(3) Updated extraction of raster layer values per GIFT region and new raster resources.

(4) Updated phylogeny

30 May 2022: GIFT version 2.2

New checklists (with a focus on endemic species) and traits for various oceanic archipelagos (Cook Islands, Madeira, Arctic Islands, Cayman Islands, Comores, Juan Fernandez, Palau, Galapagos, Frisian Islands, Antilles, Japan, Mayotte, Fiji, Taiwan, etc.) and various mainland regions (Equatorial Guinea and the entire former USSR in sub-regions).

21 May 2021: GIFT version 2.1

New checklists and traits included for the Americas, Crimea, Madagascar, Arabian peninsula, Laos, Bhutan, India, China, Sunda-Sahul shelf, Tonga, Canary Islands, West Africa and for ferns and palms globally. Large categorical trait data included from Try.

01 September 2019: Release of GIFT version 2.0

New checklist and trait data included for Europe, the Mediterranean, temperate Asia, Panama, Japan, Java, New Zealand, Easter Island and the Torres Strait Islands:

535,000 new species-by-region occurrences and 85,000 new trait records!

Updated workflows to document biases in the distribution of trait data:

(1) trait records based only on referencesthat potentially introduce biases due to covering only specific groups of species (e.g. all trees, climbers, epiphytes, etc.) or taxa (e.g. all gymnosperms, orchids, etc.).

(2) trait records based on logical imputation that potentially introduces biases (e.g. deriving growth form from life cycle in the case of annuals [-> herbs], but not perennials [-> no clear imputation possible]).

Updated taxonomic trait derivation:

(1) GIFT now includes negative trait records at higher taxonomic level, i.e. taxon x never exhibits value y in trait z.

(2) Derivation also of trait values above species level (positive and negative).

Final trait values and agreement scores for trait values from several resources are now calculated separately including and excluding restricted resources.
