Add invasive species status (GRIIS)

Source: R/add-griis.R
add_griis.Rd

Joins GRIIS (Global Register of Introduced and Invasive Species) status to a taxify() result, filtered by country. This is the source-named door for GRIIS; GloNAF (add_glonaf()) carries related naturalized-alien status.

Usage

add_griis(x, country, cols = NULL, verbose = TRUE)

Arguments

x

A data.frame returned by taxify().

country

Character. ISO 3166-1 alpha-2 country code(s), or "all".

  • Single code (e.g., "AT"): adds invasive_status column (no suffix).

  • Multiple codes (e.g., c("AT", "DE")): adds invasive_status_AT, invasive_status_DE.

  • "all": adds one column per country in the dataset.

List the codes GRIIS covers with enrichment_groups("griis").

cols

Which columns to attach. NULL (the default) attaches the curated set; a character vector of column names attaches just those, and "all" attaches every column the source carries (see enrichment_cols()).

verbose

Logical. Default TRUE.

Value

The same data.frame with additional column(s):

invasive_status

One of "native", "introduced", "invasive", or NA if not recorded for that country.

Details

Source: GRIIS (Zenodo combined CSV, CC BY 4.0, 196 countries). Coverage: ~23k name x country combinations.
