You can answer questions such as “What species is this?” and “What is this species’ diet?” when you utilise the NatureMetrics DNA-based technologies to overcome barriers associated with conventional methods of identifying specific species and dietary compositions.

Your Analysis Options


Species ID
Diet Assessment

Species ID:

You can choose a targeted Species ID test to identify specific species from its faeces.

We can successfully perform this analysis for a range of taxonomic groups including bats for example to ID the Bechstein’s bat or the Brown long-eared bat. Another common group of interest is otters, and our species ID can competently confirm the presence of otters from otter spraint.

The methods we use to identify species from faeces are qPCR or Sanger Sequencing. These analyses yield highly accurate results in describing the DNA of specific target species from faecal samples.

Diet Assessment:

You can determine the dietary composition of mammals and birds by conducting a Diet Assessment.

The DNA analysis of faecal matter provides a higher resolution identification of prey species, regardless of the species life-stage, size or body type.

We use metabarcoding to detect diverse taxonomic groups present in samples- this method of analyses is impressively effective when the dietary compositions are of a different taxonomic group than that which is eating.

You can gain insight into the diets of:

  • Piscivorous otters and the fish species that make up their prey.
  • Insectivorous bats and the insects and invertebrate species that make up their diet.Birds and the species of fish that make up their prey.

    Assess The Impacts

    Diet Assessments can inform the adaptive management of habitat restoration and help measure biological responses to changes in the environment.

    NatureMetrics have been collaborating with clients to create successful monitoring programmes since our inception, and are highly trusted in our field. If you’re looking to implement a monitoring programme with regular Diet Assessments, then contact us to discuss your project requirements.

    NatureMetrics: The Science in Action!

    Collaborating with Chris Damant at Bernwood ECS Ltd, NatureMetrics performed DNA Metabarcoding to reveal the relative contribution of woodland and non-woodland prey species to the diet of the Bechstein’s bats in Bernwood Forest, South Oxfordshire.
    This project holds great significance. Not only is it the first time DNA Metabarcoding has been combined with the Pantheon database to infer habitat characteristics, but it can also offer prominent insight into the impact of habitat loss due and the effect of such on Bechstein’s bat populations.

    Frequently Asked Questions


    From what species do you analyse?

    We have well validated bespoke pipelines that can identify all 18 native bat species and that can confirm otter spraints. Other species can be identified using more universal sequencing assays, so please get in touch with us so that we can help you ( We currently only accept domestic samples.

    How much faeces do I need to collect?

    Generally speaking, more faeces = more DNA. The degraded nature of these samples, especially by the time they are collected, leads to poorer quality and lower quantity DNA. Having said that, we have returned conclusive identifications from a single pipistrelle pellet.

    How do I store the faeces?

    Dry and in an airtight container. For bat pellets we recommend you use 1.5 ml tubes, which we can provide if needed.
