clay A fine-grained soil that tends to retain water. resource
chalk A fine white limestone rock. Soils are soft, often mixed with sand. resource
CE (Global) Critically endangered globally status
CE (European) Critically endangered in Europe status
CE Critically endangered in Great Britain status
carrion Species that are associated only with carrion (as opposed to both dung and carrion). resource
canopy Species that live within the leaf canopy of a tree or shrub. resource
cambial layer submerged Species associated with submerged trunks and branches, also classed as coarse woody debris in the wetland classification resource
cambial layer The layer directly beneath bark that transfers food within the trees. resource
calcareous substrates Soils that are mostly or partly composed of calcium carbonate. They can be split into chalk and limestone. resource
Calcareous grassland fidelity score A measure of how strongly species are associated with calcareous (chalk and limestone) grassland habitats. quality index
bumble bee nests Species that are associated with nests of true bumblebees (Bombus spp.), especially underground nests. Includes the cuckoo bumblebees that are inquilines in the nests of true bumblebees, plus species that are parasitoids or scavengers in the nest. resource
broadleaved only A deciduous tree (such as oak, beech etc.) that has wide leaves, generally shed in autumn, as opposed to the needles on conifers. resource
Broad biotope The top-level division into broad ecological groups. general glossary
brackish pools & ditches A habitat influenced by both saline and fresh water. This often means that the water is saline but less saline than the sea. Such habitats occur in pools and ditches in the upper saltmarsh or alongside freshwater seepages. habitat
brackish dune slacks Low lying depressions between the foredunes and the main dunes. These often fill with water to form temporary pools. These particular slacks have a saline influence and the water within them is brackish. Currently classed as a specific subset of brackish pools and ditches. resource
birds Invertebrate that is parasitic on birds. label
bird nests Species associated with bird’s nests, where they may be detrivores or predators of other invertebrates. resource
beneath tight bark Bark and wood in the early stages of decay, where the wood still produce saps and the bark is difficult to peel off. resource
beneath scorched bark Bark affected by fire. resource
beneath mouldy bark Bark covered in moulds. resource
beneath loose bark Loose bark is that which is easily stripped off and often well-separated from the cambial layer underneath. resource
beetle galleries Species associated with bark beetle galleries and similar. resource
bats Invertebrate that is parasitic on bats. label
base-neutral Freshwater with base-rich to neutral status. resource
base status A measure of the degree of acidity or alkalinity within the habitat. subheading
base rich seepage These open seepages are confined to limestone districts and to a lesser extent chalk. Sometimes they can be found in base-rich seepages and springs arising from glacial clays and sands which are rich in calcium carbonate. resource
base rich Associated with sites that are of generally high pH, as a direct result of the nature of the geology. resource
base Freshwater with base-rich status, such as chalk rivers, marl lakes or within calcareous lowland fens. resource
bark predator A species that uses bark surfaces to hunt and prey on other invertebrates. resource
bark (feeding on) A species that feeds on the bark of trees and shrubs. resource
bark & sapwood decay The assemblage type is found in and around trees and shrubs generally, but especially in older specimens. The assemblage is primarily associated with death and decay of the outer woody tissues of the trees or shrubs - the sapwood and bark. SAT
bark & cambium Deadwood where the bark remains attached and where the species develop either within the long dead outer bark tissues, the more freshly dead lower bark (phloem), or the cambial layer below. resource
bare sand & chalk This assemblage contains species that are associated with hot, dry soil conditions normally found in bare ground in early successional habitats. SAT
bankside trees Large shading trees along the edge of a river / stream channel, often with exposed roots within the water course and overhanging branches that can be submerged in the water. resource
arboreal A habitat in and on trees, including the canopy, trunks and branches. habitat
