red rot Fungal rot that does not destroy lignin, leaving a crumbly red-brown material. resource
reed-fen & pools This assemblage type is mainly restricted to topogenous mires and fens. SAT
Reported condition Reported condition (favourable or unfavourable) of the assemblage, with level of confidence determined by ISIS compliance general glossary
Resources The third level of the Pantheon hierarchy, showing resources (such as structural features and food sources) considered important for species to complete their life cycles. general glossary
rich flower resource This is a resource-based assemblage type that is expressed across a large range of habitats. SAT
riparian sand The assemblage type is found on soft, bare or sparsely vegetated exposed riverine sediments ranging from fine sand mixed with silt to coarse sand mixed with cobbles. SAT
riparian sand Soft, bare or sparsely vegetated exposed riverine sediments ranging from fine sand mixed with silt to coarse sand mixed with cobbles. resource
riparian shingle Exposed coarse-grained riverine sediments ranging from gravel to cobbles and small boulders. resource
rocky ground Associated with rocky ground under trees. resource
rocky shore A habitat defined as the solid mineral interface between the land and the sea. It includes rock pools, crevices, vertical cliffs and barnacles under tidal influence and is subject to severe weathering by the sea. habitat
roots & underground wood Associated with decaying roots and in the bases of decaying trunks or stumps, or with up-ended root plates. resource
rot hole detritus Species associated with decaying organic matter within rot holes. resource
rot holes Cavities within the heartwood, often created where lateral branches have died and broken off. resource
running water Habitats along stretches of rivers, streams and stronger spring-fed seepages where water action removes or retards vegetation, scours sediment to reveal bedrock or boulders or deposits fresh shingle, sand or silt. habitat
S41 Priority Species Priority species listed under Section 41 (S41) of the 2006 Natural Environment and Rural Communities (NERC) Act. status
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
saline silt Silts in coastal situations that are strongly influenced by saline water. resource
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
saltmarsh & transitional brackish marsh The assemblage type is mainly found in areas that are inundated by spring tides or storm surges. SAT
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
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
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
sandy beaches The assemblage type is found on sandy shores subject to tidal disturbance. SAT
sandy river An in-channel, submerged habitat with a sandy river bed. resource
sap runs (adult) Species that feed on sap as adults. resource
sapwood & bark decay Species associated with the outer layers of decaying wood in various situations, on both young and old trees. 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
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
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 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-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
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
seeds Species feeding on the seeds of the plant. resource
