species_codings: Supported Species Codings in the Package ForestElementsR

Description

Data of all supported species codings in the package ForestElementsR. Currently supported codings are

master

The master species coding is the original species coding used by the package ForestElementsR. It contains each species from the species_master_table and no species groups. This coding corresponds directly to the species_master_table. Its species_id's (see below) are the master table's columns genus and species combined into one character string, separated by an underscore.

tum_wwk_short

The tum_wwk_short species coding is one of two codings in use at the Chair of Forest Growth and Yield Science. It defines only a small set of single species explicitly (the most important ones in Central Europe), while all other species are attributed to a few large container groups.

tum_wwk_long

The tum_wwk_long species coding is one of two codings in use at the Chair of Forest Growth and Yield Science. It defines a larger set of single species than the tum_wwk_short coding. In its original version, this coding contains several species groups, but most of these groups are ambiguous as they include species which also have a single coding. These ambiguous groups were not included in this package.

bavrn_state

The bavrn_state species coding is the species coding used by the Bavarian State Forest Service.

bavrn_state_short

The bavrn_state_short is a coding that combines the species of bavrn_state into groups. These groups are typically used by the Bavarian State Forest Service in aggregated evaluations.

ger_nfi_2012

The ger_nfi_2012 species coding is the species coding used by the German National Forest Inventory of 2012 bwi3_methods_2017ForestElementsR

Usage

species_codings

Format

A tibble containing the supported species codings together with the coding tables (which are tibbles themselves). Its columns are:

species_coding

name of the coding

code_table

tibble describing the species coding with the columns

species_id

the species code (character)

species_name_sci

the scientific species name (for species groups english terms are used)

species_name_eng

English species names

species_name_ger

German species names
