Extinct globally |
status |
exposed chalk |
Chalk and chalk covered by a thin layer of moss and / or lichen, but with the substrate being particularly obvious. |
resource |
exposed clay |
Clay and clay covered by a thin layer of moss and / or lichen, but with the substrate being particularly obvious. |
resource |
exposed riverine sediments |
Exposed riverine sediments (ERS) are present in the shoals, bars and spits present in river channels which are periodically exposed during periods of normal or lower than average flow. The sediments range in size from cobbles and boulders to sand and fine silts. |

exposed sand |
Sand and sand covered by a thin layer of moss and / or lichen, but with the substrate being particularly obvious. |
resource |
exposed sea-cliff |
A feature of coastal situations where wind and salt blast on rocky coastal cliffs combine with shallow freely-draining soils to restrict establishment of plants along exposed cliff edges. |
SAT |
extinct |
species fomerly existing as native populations but now considered extinct |
label |
Extinct |
Listed as Red Data Book Appendix (RDB app.) - Extinct |
status |
fast flow |
Water flow with a high energy. In times of high flow vegetation is regularly scoured from the channel leaving shingle boulders and sand. Most often associated with upland streams and high energy rivers. |
resource |
fast flowing streams & waterfalls |
The assemblage type is found within and on the margins of fast-flowing streams, especially in moss on bedrock and boulders often in the splash zone of waterfalls and torrents. |
SAT |
fleshy fruits |
Fruits such as apples and plums. |
resource |
flour mills/bone works |
Species associated with human activities and feeding on flour or bone products |
label |
flow |
A resource category within the running water habitat, further subdivided into slow and fast flow |
subheading |
flowers (adult) |
Species as adults that visit flowers for either nectar, pollen or to hunt for prey. |
resource |
flowers, buds & shoots |
A species that feeds on flowers, or the young buds and shoots before they form. |
resource |
foliage |
Foliage feeders, including leaves, shoots, fruits and seeds. |
resource |
freshly dead |
Freshly dead trunks and boughs support a specialist early successional fauna, with most species using both standing and fallen/felled wood. |
resource |
freshly dead/exposed |
Roots that have only recent been exposed to the air. |
resource |
freshwater seepages |
Freshwater seepages, often on beaches, that run through coastal habitats. These are often very small, shallow and discreet, sometimes surrounded by reeds and other vegetation. |
resource |
fungal fruiting bodies |
A large variety of wood-decay fungi are active in all types of woody tissues from heartwood through to twigs and roots. All produce fruiting bodies on the outside of the decaying wood and above ground, which are exploited by this assemblage type. |
resource |
fungal fruiting bodies (ISIS) |
The assemblage type is found in and around trees and shrubs generally, but especially in older specimens. A large variety of wood-decay fungi are active in all types of woody tissues from heartwood through to twigs and roots. All produce fruiting bodies on the outside of the decaying wood and above ground, which are exploited by this assemblage type. |
SAT |
Grazing marsh ditches: salinity index |
A measure of the tolerance of aquatic invertebrates to saline or brackish conditions in floodplain and coastal grazing marsh ditch systems. |

A score based on the conservation status of aquatic species associated with ditch systems in floodplain and coastal grazing marshes. |

A label used (under the Resources heading) to group together habitat-related subdivisions |
subheading |
heartrot |
There is a succession of invertebrates colonising and later dying out as the heartwood is gradually decayed by specialist decay fungi (predominantly the larger bracket fungi), cavities form, and debris accumulates in the base and composts down into wood mould.
|
resource |
heartwood decay |
The assemblage type is found in and around mature and ancient trees and shrubs. |
SAT |
heavy shade |
Species associated with heavier shade conditions, within sheltered woodland |
resource |
hollow tree cavities |
Cavities in the heartwood that contain nests of birds, mammals or other invertebrates. |
resource |
honeydew & sap runs (adult) |
Species that feed as adults on honeydew (the sugar-rich liquid secreted by aphids and some scale insects as they feed on plant sap) or directly on sap |
