Titlesort ascending Summary Tags
trunks & branches Species associated with the outer layers of decaying trunk and branches. resource
trunk & branches Arboreal species associated with the trunk and branches (as opposed to the leaf canopy) of living trees. resource
tree-associated A biotope associated with woodland and wood-pasture systems. broad biotope
tree pools Tree associated pools come in many forms. These are not rot holes in the sense of being derived from fungal decay of wood, but cavities in which debris rots. resource
tidal litter An accumulation of dead plant remains and other material either on the surface or buried by wave action in the top layers of sand and silt. resource
terrestrial aspect Many species have a terrestrial aspect to their lives. This could include pupation in the soil, feeding on the ground in fruits that have fallen etc. resource
temporary water dependant Small water bodies (small ponds, depressions or ruts) that completely dry up for part of the year, leaving no standing water. Usually free of fish and other predators that require a water body all year around. resource
tall sward & scrub Areas of dense herbage or partial shade where a humid microclimate is maintained at ground level. Dominance by woody plants is limited by exposure, grazing or cutting of vegetation, but they often form an important component of the habitat. habitat
synanthropic Associated with humans, either by feeding on resources provided by human activity, or living in structures built by humans. label
sward/field layer The structural layer of grasses, herbs and dwarf shrubs in an open system. The architecture includes shoots, leaves and flowers. resource
sub live Species associated with living subterranean tree roots. resource
sub decay Species associated with subterranean tree roots that have been affected by some form of decay. resource
stumps Tree stumps left within the ground. resource
stream & river margin The assemblage is found along rivers and streams passing though floodplains with sand as a major component, and appears to be restricted to the west and north of Britain. SAT
stored food products Synanthropic species associated with stored food products. label
stones, boulders, shingle and scree Larger sized boulders, rocks and bare stone screes, frequently associated with mountain slopes and strong erosive forces, but offering a sheltered matrix. resource
SQS Species quality score general glossary
springs & caves Fully subterranean and surface transition zones with flowing water. Species in this zone are often flushed out from the aquifer onto the surface near the source. resource
sphagnum/moss lawn Carpets of moss (often Sphagnum) found in permanently, often very acidic, wet habitats. These may be formed into hummocks, or semi-submerged at the edge of a waterbody. resource
Sphagnum bog An assemblage type associated with Sphagnum bogs, usually in acidic conditions and largely restricted to rain-fed (ombrotrophic) or spring-fed (soligenous) mires. SAT
Spermatophytina A grouping of plants that includes all the seed-bearing species, as opposed to the 'cryptogams' such as mosses and ferns that reproduce via spores. general glossary
Species Quality Indices A measure of the number of rare species in a sample, divided by the total number of species in the sample. general glossary
solitary wasp nests Species that are associated with solitary wasp nests within dead wood (not including the solitary wasps themselves). The wasp nests are often within pre-existing beetle bore-holes. resource
soil type Contains sand, windblown sand, clay, ball clay, calcareous, chalk and limestone clay soil types. subheading
soil humidity Categorises species associated with different levels of soil humidity: dry, damp or wet (or variable). subheading
soil & roots Species living deep within the soil. They may be free living, or directly associated with the roots of plants. resource
soft rock cliff seepage Slumping cliff areas can sometimes expose groundwater sources which then form seepages down the cliff face. These vary from little more than constantly damp ground surfaces, to more significant streamlets with plant communities which can include Phragmites and Juncus. resource
snow bed An area of late-lying or near permanent snow and ice packs that cover the higher mountain slopes throughout the year. resource
snail shells Empty snail shells utilised by non-molluscan invertebrates. resource
slow-flowing rivers The assemblage type is found in slow-flowing rivers on silty substrata, generally in lower and middle catchments. SAT
slow flow Water flow that does not have the energy to scour away vegetation, often leaving fringing vegetation. Silt deposition is common. Associated with canals and sluggish rivers. resource
short sward & bare ground In lowland habitats where disturbance removes vegetation to create areas of bare or sparsely vegetated ground. habitat
shingle banks This assemblage is dependent on repeated turnover of coarse grained sediment by spates and so is sensitive to management of river channels, river catchments and changes in rainfall patterns. SAT
shingle Rocky substrates larger than sand, and formed of pebbles and stones. Often found on beaches. Note - different from riparian shingle that is found next to rivers. resource
shallow water Standing water that tends to be just a few centimetres deep. As such it is often a lot warmer, favouring plant growth as well augmenting animal activity. resource
shallow freshwater pond A pond (generally up to 2ha in area) is a body of standing water, either natural or man-made, that is usually smaller than a lake . Freshwater ponds are those that are not affected by a high salinity. resource
