Nursery stock: what you grow, where it already stands and what it needs
The nursery-stock database brings together what tree nurseries and fruit growers want to know: which trees municipalities plant, which fruit varieties and rootstocks are registered, which forest seed sources are approved, what a species needs from its site and which pests affect it. Every fact carries its source.
Municipal trees with a known planting year, per decade. The 2020s are still running.
One place where tree data comes together, and flows back into your decisions
On the left the sources: municipal tree inventories, variety lists, approved seed sources, site values, pests and records worldwide. In the middle FairGrow links them per species and cultivar. On the right you see where it ends up.

What municipalities plant now, and what they planted before
From the open tree inventories of more than twenty Dutch municipalities and one province you see, per species and cultivar, how many trees stand where and in which decade they were planted.
That shows which cultivars have been gaining ground since 2016 and which are disappearing: a signal for what you will sell in five years.

The whole story of a species in one window
Click a species and everything about it opens in one window, without losing your place in the list.
Photos with creator and licence
Up to six per species, never the same one twice in a row.
Where it stands
The municipalities with that species, with counts and planting years.
Worldwide
The countries with open records, and the countries where the species is native.
Pests and diseases
Host relations from the EPPO Global Database, with one click to the authorised products for that pest.
Site
Light, moisture, acidity and nutrients from the Ellenberg values, plus nectar production and ecological value.
Seed sources
For forest species, the approved seed sources per country.
Photos and traits
Pedunculate oak: six photos, and the site values with the source of each number.
Where it stands and when it was planted
Per municipality the number of trees, the planting years per decade and the cultivars.
Fruit: varieties, rootstocks and resistance
The EU variety list for fruit, completed with the Swiss and Polish registers, with the Malling-series rootstocks.
For apple, measured resistance to scab and mildew from the gene bank in Dresden-Pillnitz, so you see at a glance which variety carries Rvi6.
Forest reproductive material: approved seed sources
The official EU list of approved basic material, with the seed sources from 28 countries on a map. Your own country comes first.
We keep the register names exactly as the member state publishes them, so you can find a source back in the national register.
A quick tour of the screens
Small pieces of the app, each with what it gives you.
Worldwide
The countries where the species has been recorded, from open GBIF records, also as a planted tree. Where it is native comes from BGCI GlobalTreeSearch.
Pests with a link to products
Every host relation from EPPO, with a link to the products authorised against that pest in your country.
Only data you may actually use
We switch a source on only when its licence allows it: CC0, CC BY, public domain or an open government licence. If the licence is unclear or rules out commercial use, we ask the owner first and leave the source out until they answer.
Built on open data
Eight kinds of sources, each cited in full in the app.
Open municipal tree inventories
More than twenty Dutch municipalities and the province of Gelderland publish their trees with species, cultivar and often the planting year.
FOREMATIS
The European Commission list of approved basic material for forest reproductive material (CC BY 4.0).
EU Plant Variety Portal
The EU variety list for fruit (CC BY 4.0), completed with the Swiss and Polish registers.
Ellenberg-type indicator values
Light, moisture, acidity, nutrients and salt for European plants (Tichy et al. 2023, CC BY 4.0).
Nectar in urban green
Nectar sugar per flower per day (Tew et al. 2023, CC0).
Register of ecological trees
The ecological score per tree of the City of Leiden.
EPPO Global Database
Host plants and pests, with the EU regulatory status.
GBIF, iNaturalist, Wikimedia Commons
Records worldwide and photos, each with creator and licence.
Not finished yet, and labelled as such
Two parts are not there yet. We say plainly what is missing.
Planting year for a few municipalities
Raalte, Almelo and Velsen do not publish the planting year openly yet.
Traits per cultivar
Height, crown shape and hardiness are scarce as open data. The app falls back to the species.
Questions we get
Why is my municipality not included?
We only use tree inventories that a municipality publishes openly itself, under a licence that allows use in a product.
Is “Worldwide” a distribution map?
Partly. The records show in which countries the species has been recorded, also as a planted tree. The countries where it is native come from BGCI GlobalTreeSearch and have their own colour on the map.
Why no nursery catalogues or the list of names of woody plants?
They are not open. We only include them once the owner gives permission.
In which languages does it work?
In 57 languages. Names appear in your language wherever a source has them; otherwise you see the scientific name.
Can I add or correct something?
Yes. Report it through the Help window in the app; we check every report.
