Retrieve the taxon id
In order to access information about the elephant, we first need to retrieve its Species+ taxon identifier. For this, we use the spp_taxonconcept() function and the elephant’s scientific name, Loxodonta africana, as query_taxon argument.

#> Information available: $all_id, $general, $higher_taxa, $accepted_names, $common_names, $synonyms, $cites_listingsAs the first column of the output shows, the taxon identifier of the elephant is 4521. This taxon_id will be used for all next function coding.
Beyond the taxon identifier, the output also provides information about the taxon classification and other names, both synonyms and common names if any, in different languages.
Map the elephant’s distribution
Before giving more insights into the legislation status of the elephant, we have a look at where the elephant actually occurs naturally. For this, we can access the elephant’s distribution information with the spp_distributions() function. Thereafter, we can map the distribution with the help of the rworldmap package.
library(rworldmap)
par(las = 1)
elephant_distr <- spp_distributions(taxon_id = "4521",
verbose = FALSE)$distributions
map2 <- joinCountryData2Map(elephant_distr,
joinCode="ISO2",
nameJoinColumn = "iso_code2",
nameCountryColumn = "name")#> 42 codes from your data successfully matched countries in the map
#> 0 codes from your data failed to match with a country code in the map
#> 201 codes from the map weren't represented in your dataplot(c(-23, 62), c(45, -40),
type = "n",
main = "Loxodonta africana",
xlab = "Longitude",
ylab = "Latitude")
plot(map2, add = TRUE)
plot(map2[!is.na(map2$iso_code2),], col = "#cba74d", add = TRUE)
Access the legislation status
The functions spp_cites_legislation() and spp_eu_legislation() provide access to the legislation status information of the elephant.
First, we have a look at the CITES legislation status:

Access the elephant’s Species+ reference data
Last but not least, it is important to identify which references the Species+ information about the elephant is based on. For this, we can access the Species+ reference data with the spp_references() function.
