| Seepage fidelity score - acid-neutral |
Seepage fidelity score for species associated with acid-neutral seepages |
quality index |
| seepage |
This wide ranging assemblage occupies a range of seepage types from shaded seepages to open calcareous seepages. |
SAT |
| seeds |
Species feeding on the seeds of the plant. |
resource |
| sea cliff |
Hard rocks forming vertical and near vertical cliff faces at the coast, supporting invertebrates that utilise rock crevices and bare ground, as well as associated thin soils and open vegetation at the cliff top. |
habitat |
| scrub-heath & moorland |
The assemblage type is found on nutrient-poor, acid soils where herbaceous or dwarf shrub vegetation is dominant, although trees and taller shrubs can be an important component of the overall habitat. |
SAT |
| scrub edge |
The assemblage type is found where scrub or woodland grades into or is interspersed with open areas of grassland, heathland or early successional vegetation types. |
SAT |
| scrub at wood edge/glade |
Species only associated with scrub and understorey at the wood edge or within a glade where there is direct sunlight but the conditions are sheltered. |
resource |
| scrub |
A sub-woodland tree resource, formed of either young tree species, or those forming woodland understory in woodland, either as woodland edge or as an invading resource into other habitats. It has value in offering shelter, micro-climates, and additional structure to invertebrates, but can diminish other resources if unchecked. |
resource |
| scorched wood |
A small number of species are only known from fire-damaged wood, or are most regularly found in this situation. Others are associated with bonfire sites. |
resource |
| sapwood & bark decay |
Species associated with the outer layers of decaying wood in various situations, on both young and old trees. |
resource |
| sap runs (adult) |
Species that feed on sap as adults. |
resource |
| sandy river |
An in-channel, submerged habitat with a sandy river bed. |
resource |
| sandy beaches |
The assemblage type is found on sandy shores subject to tidal disturbance. |
SAT |
| sandy beach |
A habitat which includes the drift line and immediate upper intertidal and supralittoral zones of seashore dominated by sand and, to a lesser extent, shingle. The habitat is saline and subject to tidal disturbance, augmented by storm surges at irregular intervals. |
habitat |
| sand |
A granular material consisted of finely divided rock particles often found underlying heathland, dunes and some grassland systems and can be interspersed with larger rocks and cobbles. |
resource |
| saltmarsh vegetation |
Terrestrial plants including reeds, grasses, herbs and rushes that tend to form dense stands, stand tall and root in wet soil and/or water. |
resource |
| saltmarsh & transitional brackish marsh |
The assemblage type is mainly found in areas that are inundated by spring tides or storm surges. |
SAT |
| saltmarsh |
A habitat dominated by plants and covered by saltwater at high tide. They are restricted to less exposed shorelines, characterised by net deposition of fine sediment. However, they are still defined by levels of salinity and tidal disturbance. |
habitat |
| saline silt |
Silts in coastal situations that are strongly influenced by saline water. |
resource |
| saline lagoon |
A relatively rare aquatic habitat heavily influenced by sea water but not wave action. Subjected to evaporation or precipitation makes them vary between hyper-saline and weakly saline throughout the season. |
habitat |
| S41 Priority Species |
Priority species listed under Section 41 (S41) of the 2006 Natural Environment and Rural Communities (NERC) Act. |
