Guidelines for the Selection of Biological Heritage Sites

7. Section 2: Species Guidelines

7.8 INVERTEBRATES:  OTHER INVERTEBRATES

Application (all invertebrate guidelines)

Identification of sites on the basis of their invertebrate animal species should take account of the needs of many invertebrates for habitat and structural diversity, both at the 'macro' and 'micro' scales.  Small-scale habitats of particular importance to some invertebrates, such as dead wood or small patches of bare ground, occur and indeed may shift their position over time within large scale habitats e.g. woodland or grassland, on which the invertebrates also depend.  Moreover the larval and adult phases of the same species often need quite different habitats.  Invertebrates generally have annual life cycles, and their survival on a site depends on the continued availability of the right mixture of habitats at the right time of year - every year.  Such factors should be taken into account when determining site boundaries.

Species lists, especially for less well-recorded groups of invertebrates, should be regarded as tentative.  They include species recorded in Lancashire since 1950, those not recorded since 1978 being shown with an asterisk, or other notation.

It should be noted that the category 'nationally scarce', referring to species believed to occur between 16 and 100 10km squares of the National Grid, is sometimes subdivided in relation to invertebrate groups into 'Notable A' and 'Notable B'.  This subdivision has not been recognised in the following guidelines.

Justification

In Lancashire, as elsewhere, there are more species of invertebrate animals than of all plants and other animals combined.  Many invertebrate groups and species have declined dramatically in recent decades, and their conservation is a matter of widespread concern in Europe.  Until recently, it was thought that if sites were selected (and managed) on the basis of their botanical interest, then the invertebrates would automatically be catered for too.  This is not so:  it is important that due regard is paid to the contribution that invertebrates make to biodiversity, and of their habitat needs, in their own right, insofar as available information allows.

With such a large number of invertebrate groups, and the relative lack of knowledge about many of these, it is impossible to develop individual sets of guidelines for every species-group at the present time.  Where there is an adequate database for a particular species-group relating to Lancashire, specific guidelines have been devised and appear below.  For the remainder, there is a single, 'catch all', section which follows the standard approach adopted throughout the species section.

v)  OTHER INVERTEBRATES

Application (all Other Invertebrate guidelines)

The following guidelines should be applied to any invertebrate groups not covered elsewhere, including those for which no species are listed under the relevent guideline.  Records of difficult or critical taxa should be subject to confirmation by a regional or national referee or other expert.  Account has been taken of the provisional changes to Red Data Book status which are made in the national species-group reviews produced by the Nature Conservancy Council and its successor the Joint Nature Conservation Committee.  The species lists below are known to be incomplete.  These lists include species recorded in Lancashire since 1950, those not recorded since 1977 being shown with an asterisk or other notation.  Only sites from which relevant records have been made since 1987 should usually be considered for designation as Biological Heritage Sites.  However, consideration may be given to sites where records have been made between 1978 and 1986 where no gross habitat changes are evident that are likely to have affected the species concerned.  Records made between 1950 and 1977 are considered to require confirmation and sites which qualify only on the basis of such records should be identified as provisional entries.

The species are listed in family order (Recorder version 3.21b) then alphabetically within families.


In1 Any site which regularly supports a population of an invertebrate species which is specifically protected under the Habitats Directive and/or listed in Schedule 5 of the Wildlife and Countryside Act 1981 (as amended) and/or British Red Data Books: 2 Insects(1) or British Red Data Books: 3 Invertebrates other than insects(2), and not included under any other guideline.

Application

All sites in the above categories should be included.  Relevant species records have been identified mainly from the Invertebrate Site Register (Parsons 1987) and national species-group reviews (see References).  Species to which this guideline may apply include:

In3 Any site which regularly supports a population of an invertebrate species which is recorded from three or fewer localities in Lancashire not included under any other guideline.

Application

Any site in this category may be considered for inclusion.  However, systematically obtained recent information on these groups of animals is insufficiently advanced for relevant species to be listed. However, the following species is believed to satisfy the terms of the guidlines:

INVERTEBRATES OTHER THAN INSECTS
Moss Animals (Bryozoa)
Plumatella fungosa A moss animal

In4 Any site which regularly supports a significant proportion of the Lancashire population, or contributes significantly to the range in Lancashire, of an invertebrate species which is recorded from more than three localities in the County, but which could be at risk because of very small populations, recent rapid decline or habitat loss or change, and which is not included under any other guideline.

Application

It is considered that recent systematic recording of the animal groups concerned is insufficiently advanced to allow the application of this guideline.
