Establishes application to four Zurich urban parks and a single model Trees class.

Assessment findings

Namesupported
Evergreen Tree matches the coniferous-tree category used for the published conductance value.
Targetsupported
Maximum vegetation conductance is a property of the land_cover.evetr target.
Valuessupported
Järvi et al. (2011) Table 2 publishes conifer maximum conductance as 7.4 mm s-1, exactly matching the stored value.
Sourcesupported
Järvi et al. (2011) is the publication that prints 7.4. Stagakis et al. is retained as the later Zurich application context; its article and Supplement Table S3 do not publish maximum conductance.
Placecuration required
The value is a published conifer model parameter rather than a Zurich-derived measurement. Stagakis establishes Zurich application context but does not document this value in its parameter table.
Representativenesscuration required
The Zurich study evaluates four urban parks and does not establish a city-wide evergreen conductance value; whether a literature default applied there should remain city-classed requires curation.
Methodsupported
The record transcribes a parameter published in earlier literature.
Identitycuration required
Stagakis uses a single Trees parameter class even though this database keeps separate Zurich deciduous and evergreen conductance records. The source correction does not settle whether both identities should remain.

Scientific note

The parameter source is now settled: Järvi et al. (2011) publishes the exact 7.4 mm s-1 conifer value, while the later Zurich study does not print maximum conductance. The stable path and Zurich place retain the application context, not an assertion that the value was derived in Zurich. Human curation is still needed for the city-scale claim and for the separate evergreen identity, because Stagakis evaluates four parks and parameterises one Trees class rather than distinct evergreen and deciduous classes.
