|Tools for this tag|
A single tree, often lone or significant.
How to map
Place a node () at the location of the tree's trunk with the tag natural=tree.
- leaf_type=broadleaved/needleleaved - describes the type of leaves.
type=broad_leaved/conifer/palm- Caution: The usage of type=* for non-relation elements should be avoided! (use leaf_type instead)
- genus=* - scientific name of the genus (first part of the scientific name). If you add species=* this is not necessary.
- species=* - scientific name of the species (popularly known as the Latin name). Please use the namespaces for local languages (see examples).
- taxon=* scientific name describing any taxonomic level e.g. order, family, genus, species, sub-species or cultivar
- sex=male/female. Some species are dioecious, meaning that an individual has only male or only female flowers. A good known example are all willows (Salix).
- circumference=* for the circumference of the trunk (measured in a height of 1 metre above ground). If no unit is given metres are assumed.
- height=* for the height
- name=* for individual trees which have a name, usually these are either individual trees with a historical or traditional name or trees with a name given in memory of special events (> memorial tree). The usual rules for name=* apply. This tag should not be used for a description of the species.
- leaf_cycle=deciduous/evergreen/semi_deciduous/semi_evergreen - describes the phenology of leaves.
Subtag denotation to indicate the significance
It can be helpful to further describe the context and significance of a tree. It can be used for some maps to enhance landmarks and to tone down or skip unremarkable trees. There are some further suggestions for this on the discussion page. denotation=* seems to be widely in use. To mark monumental trees: additional monument=yes (compare to historic=monument).
If you want to map a line of trees, have a look at natural=tree_row. (When along a road, this is sometimes called "avenue of trees", allé or allée.) This approach can also be combined with individually mapped trees for further details.
A walnut tree (common walnut):
- species=Juglans regia (this is the latin species name)
- species:en=Common Walnut
- species:de=Echte Walnuss
An oak tree (unknown species):
A spruce tree (unknown species):
A birch tree (unknown species):
A Canary Island date palm:
Renderers may use one signature for any kind of tree. If foliage dependent signatures (as above) shall be applied, the easiest solution is to evaluate the leaf_type=*, leaf_cycle=* tags. If these are unset, you can derive them from the genus. The genus is the value of the genus=* tag. It is also the first portion (substring before the first whitespace) of the value of the species=* tag.
