A-Z Search
You can select from an A-Z list of all plants known to have grown wild in Derbyshire. This is a complete alphabetical listing by scientific name of all species in Derbyshire for the letter you select.
The results will provide a summary list of all the relevant entries, showing the following information:
- Scientific Name
- Common Name
- Latest Year for which records are known
- A link to open a 2 kilometre distribution map (see distribution maps)
The scientific name will be presented as a hyperlink, allowing you to view maps, species
statistics and completed or draft accounts (see species accounts).
Keyword Search
Use the search box to return a list of matches by either scientific or common name. You can type a
whole name, or any part of it. Keep your searches short to improve the chances of a correct match.
Tick the check box to widen your search to include words, names or text strings present
in the species accounts. Be aware that if you search on "derby", you will get results
containing both Derby or Derbyshire. To exclude longer words, make sure you include an
appropriate character with your search term, eg "derby " or "derby."
The results will provide a summary list of all the relevant entries, showing the following information:
- Scientific Name
- Common Name
- Latest Year for which records are known
- A link to open a 2 kilometre distribution map (see distribution maps)
The scientific name will be presented as a hyperlink, allowing you to view maps,
species statistics and completed or draft accounts (see species accounts).
Maps and figures are based on data correct at September 2007. The accounts were originally
drafted by Dr Alan Willmot in 2003/4 and are now being updated in the light of many new records.
Note that because species and subspecies maps and accounts have not yet been merged, some
care may be needed when viewing or interpreting entries for certain taxa. Where the letters
Xx appear in the species accounts they indicate the start of
italicisation of scientific names which will eventually be required
in the book form of the Flora of Derbyshire.
Taxonomic list
You can also return a full county plant list in taxonomic order by using the "View taxonomic list" link.
Distribution maps
Maps are available for all species for which grid reference data is available.
- Large white dots represent old records, collected prior to 1987
- Smaller black dots represent modern records, collected from 1987 to 2007
- A solid black dot in a larger white dot (bullseye) represents the presence of
a species both before and after the start of 1987.
Two levels of map details are available:
- Tetrad maps, where each dot represents the presence of one or more records anywhere in an area 2km x 2km in size (known as
tetrads)
- Hectad maps, where each dot represents the presence of one or more records anywhere in an area 10km x 10km in size (known as
hectads).
Map backgrounds show a combination of topographical relief and Natural Area boundaries in red. Relief is shown in five colour bands as follows:
Yellow: Under 50m above sea level
Green: 50-150m
Blue: 150m-300m
Light Purple: 300m to 500m
Dark Purple: over 500m

Species accounts
Each account gives an overview of the plant, its county status, abundance and occurrence, especially
in relation to Natural Areas in Derbyshire. Locations are followed by Ordnance Survey
grid references, normally accurate to 1km square. Where locations are given
as specific examples they, or their grid
references, are presented in round brackets ( ). All other locations are given in non-standard brackets
[ ] to indicate they are purely examples of the geographic spread of a species; those chosen have no
particular significance above any others.
A statistics box contains information derived from Derby Museum's records database.
This includes the earliest and most recent year for which the species is known,
plus a total count of the records held. An analysis of grid square coverage
for past and modern records is given, based on monads, tetrads and hectads. (i.e. grid squares, that
are respectively 1km, 2km and 10kilometre in size). Information on
each plant's county status and conservation status is also given.
