ls_fetch_eu: Tree inventory data for 21 countries in Europe

In ropenscilabs/laselva: Access to Global Forest Inventory Data

Description

Tree inventory data for 21 countries in Europe

Usage

ls_fetch_eu(...)

Arguments

...	curl options passed on to crul::verb-GET

Value

a list of tibbles

• genus: data at the generic level

• species: data at the species level

Fields

• x/y: coordinates in a ETRS89-LAEA reference coordinate system, representing the centroid of the INSPIRE-compliant 1 kmx1 km European grid

• country: the country where the forest plot was sampled

• genus_name: the name of the genus sampled

• species_name: the name of the species sampled

• dbh_1/dbh_2: the class for the diameter at breast height of the trunk, which is used to distinguish a new recruit of a given tree. This latter measurement has a value of 1 for trunks with a diameter of less than 120 mm, 2 for trunks with diameter greater than 120 mm, and -9999 for trunks with unknown diameters. The value of 120 mm represents the common minimum threshold adopted by the nfis, although single nfis have different minimum thresholds, ranging from 0 mm in Finland to 120 mm in Cyprus and Switzerland. The choice of threshold has important implications, since estimations of biomass based on different thresholds can deliver very different results.

• nfi: 1 if the data comes from the nfi, -9999 if not

• ff: 1 if the data comes from the ff, -9999 if not

• bs: 1 if the data comes from the bs, -9999 if not

• eeo: whether or not the target occurrence falls within the species geographical range, measured as the extent of occurrence, 1 for yes, 0 for no

Acronyms

• bs: Biosoil

• ff: Forest Focus monitoring database

• nfi: National Forest Inventories dataset
