Freshwater invertebrates survey, RSPB nature reserve

Monday, February 25th, 2013

Karl Harrison, UES’ Graduate Ecologist, recently attended a freshwater invertebrate survey run by the RSPB at Coombes Valley Nature Reserve, Staffordshire.

The caterpillar of the Argent and Sable moth encases itself in birch leaves

The site is an oak woodland located in the steep sided Coombes Valley. It attracts a variety of woodland breeding birds including; flycatchers, redstarts and wood warblers. The site also has a small population of rare Argent and Sable moths (see photo).

The samples were taken from a stretch of the Coombes Brook as it passes through the nature reserve. They were collected using the ‘kick-sampling’ method, where the substrate is disturbed up stream of a hand net which collects any small invertebrates and everything else flowing down stream. The content of the net was spread out on a tray and any invertebrates carefully collected.

In the makeshift laboratory the collected samples were analysed and compared to known samples, paying close attention to the features that distinguish one family from another. The invertebrate larvae we hoped to identify were Mayflies Ephemeroptera, Stoneflies Plecoptera, Caddisflies Trichoptera and True flies Diptera.

Freshwater invertebrates are a good indicator of water quality, usually determined based on the species present and their levels. For example an abundance of Stonefly and Mayfly larvae suggests good oxygen levels and low levels of pollution.

The study of freshwater invertebrates can be very useful in ecological surveys, as they provide an indication of water quality and potential presence of amphibians.

Karl will be returning to Coombes Valley Nature Reserve to observe the larvae through their development.

For more information about the reserve or volunteering with the RSPB, details can be found on the Coombes Valley Nature Reserve Webpage.

Great crested newt pond scoping survey in Lower Peover, Cheshire

Great crested newt larvae

UES were commissioned in June 2011 to conduct a great crested newt pond scoping survey to assess potential presence of great crested newts within 250m of the development footprint.

Development works within 250m of a great crested newt pond are often subject to a Natural England European Protected Species Licence (EPSL). It is stressed by Natural England to try and redesign a project to remove any potential impacts on great crested newt populations and associated habitats in order to remove the need for licensing.

The field methods used to survey ponds are:

  1. Bottle trapping
  2. Egg search
  3. Torch surveys
  4. Netting

Natural England recommend using at least three of the methods outlined above when conducting a pond survey. Smooth newts and great crested newt eggs and larvae were found in ponds within 250m of the development.

UES proposed that by designing the project timings and working methods to avoid impacts, any potential impacts on local great crested newt populations and habitats could be effectively removed, or reduced to a negligible level thereby removing the need for protected species licensing.

Great crested newt monitoring at Kings Cliffe, Northamptonshire

Tuesday, July 19th, 2011

It’s the fourth year that United Environmental Services have monitored the ponds in Kings Cliffe following a major trapping and relocation scheme. So far this year a good number of adult great crested newts and developing great crested newt larvae have been caught in bottle traps  and pond nets and recorded whilst torching. A healthy population of other amphibians including Smooth and Palmate newts have also been recorded on the site, as well as reptile species such as slow worm and grass snake.

UES caught a particularly large female great crested newt, which was heavily pregnant whilst bottle trapping. Courtship and egg-laying normally lasts from mid-March to mid-May. Female great crested newts lay eggs individually on leaves of submerged vegetation, which she then carefully folds up into a package. After about 3 weeks the great crested newt larvae hatch out and spend the next 2 to 3 months developing into juveniles, whilst feeding on a wide variety of pond life including small crustaceans and other newt larvae.

Great Crested Newt Surveys Derbyshire and the Peak District national Park

Great crested newt surveys can be carried out in Derbyshire and the Peak District national Park during spring and early summer. Pond surveys for great crested newts are undertaken at a time of year when the great crested newt population returns to the pond to breed. Great crested newt pond surveys have to be carried out to strict guidelines and so the people undertaking them must be properly trained, licensed and experienced to carry out great crested newt pond surveys. Derbyshire and the Peak District national Park has many ponds and wet areas which are suitable for great crested newts. Any action which has the potential to disturb great crested newts or their habitats must be preceded by great crested newt surveys of the pond or area, to ensure that no great crested newts are disturbed. United Environmental Services have experienced and appropriately licensed staff that can carry out great crested newt surveys in Derbyshire and the Peak District national Park. At times of year when great crested newts are not in the ponds, other survey methods can be employed. The main technique used is the habitat suitability index which is an accepted method of assessing a habitat for its suitability for use by great crested newts.

United Environmental Services carry out surveys across Derbyshire. The surveys which are carried out in Derbyshire include great crested newt surveys, bat surveys, Phase 1 habitat surveys, breeding bird surveys, water vole surveys and a full range of environmental surveys. United Environmental Services also offer landscape design and garden design services in Derbyshire and can provide the materials and implementation work if required. We have a team of experienced surveyors, landscape architects and ground workers who work to a high standard across Derbyshire.
