Seepage fidelity score - acid-neutral

Seepages are very small, flowing waterbodies. They are characterised by generally slow rates of flow, and by being extremely shallow, sometimes no more than a film of water over the substrate. This means that they are most often associated with the uppermost sections of waterbodies, being transitional to streams and rivers as they gather water lower in the catchment. They are also very often derived from springs.

IEC (Revised)

The Index of Ecological Continuity (IEC) for beetles was originally developed as a means of producing a simple statistic which could be used in grading a site for its significance to the conservation of saproxylic (wood-decay) beetles based on ecological considerations rather than rarity. Several important sites have been designated as a result of this approach to interpreting site species lists as saproxylic assemblages of ecological significance.

Exposed riverine sediments fidelity score - Coleoptera

Exposed riverine sediments (ERS) occur within river systems at the juncture of the aquatic and terrestrial, and consist of poorly vegetated alluvial deposits of silts, sands and gravels, which are habitat for a wide range of rare and highly specialised beetles. The fidelity scores used in Pantheon originate from Bates 2005 (see link below) who worked in collaboration with Adrian Fowles, who had developed a previous set of scores.
