Carlos Abrahams article on Data Information and Management in relation to bird bioacoustic surveys has been published in the December issue of In Practice.

Bioacoustic surveys can be used to capture useful and robust data on bird vocalisations to inform studies on avian distribution and ecology. However, currently there are no recognised standard methods for their use in the UK. This article sets out a draft protocol for testing and adoption, and invites feedback from CIEEM members to further develop good practice.

Below is an extract from the article:

Andrew Baker, Managing Director and founder of Baker Consultants, has been made a Fellow of the Chartered Institute of Ecology and Environmental Management (CIEEM).

In elevating Andrew to being a Fellow, CIEEM cited his outstanding contribution in the development and interpretation of nature conservation law, and his contribution to advancing the use of bioacoustics as an ecological surveying and monitoring tool.

With almost three decades of professional experience, Andrew has a particular interest in the law, and he has been very active in this area through his work with the UK Environmental Law Association (UKELA), teaching and frequent publications. This expertise is valued highly by our clients and he is a veteran of many public inquiries where his knowledge of the subject is critical.

Our principal ecologist, Barry Wright, recently led two field training workshops for the Yorkshire and Humberside branch of the Chartered Institute of Ecology and Environmental Managment (CIEEM). Taking place near Wetherby at the begining of March, the workshops were devised to help CIEEM members to identify tree and shrub species in winter, including studying twigs from 19 different species, and learn the methods available for surveying hedgerows.

As well as describing existing survey methods, Barry also gave a demonstration of his own survey method, HEDGES (Hedgerow Ecological Description, Grading and Evaluation System). This is based on Barry’s own research, can be tailored to individual project needs and enables more hedgerow information to be gathered. As well as being a principal ecologist at Baker Consultants, Barry is currently completing his research for a PhD at Sheffield Hallam University in the study of hedgerows and the species that can indicate their origins and age.

Winter hedgerow

Winter hedgerow

An assessment of the ‘importance’ of a hedgerow under the Hedgerows Regulations 1997 can be required at any time of year, but surveying hedgerows in winter can be a cold, wet and daunting task especially with no leaves in the trees and bushes to make identification easier. This increases the importance for ecologists in having skills in winter tree and shrub species identification. If ecological surveys miss hedgerow species due to ecologists being unable to correctly identify trees and shrubs during winter, this could lead to the removal of a hedgerow incorrectly deemed not to meet the minimum criteria of woody species presence.

Despite these problems, surveying hedgerows in winter has its benefits. Without leaves to get in the way, it is easier to see the structure of a hedge, such as evidence of laying, and ground flora is more clearly visible. This is beneficial, as woodland ground flora species like Bluebell, Dog’s Mercury and Lords-and-Ladies can add to the scoring for a hedgerow to be assessed as ‘important’ under the regulations. Ground flora species such as these and Ivy are often hidden under foliage in summer, unless there is vigorous growth emerging on the outside of a hedge.

Even if winter surveying of a hedgerow is not specifically required, carrying out a winter survey is still desirable, so as to complete the picture following a summer survey to record the frequency and abundance of trees and shrubs along the hedge.

Mark Woods, senior ecologist with Baker Consultants, has recently overseen the latest phase of a project to translocate species rich grassland and the dingy skipper butterfly, Erynnis tages, from a former colliery in Nottinghamshire. The project involved the creation of butterfly banks for this species and was undertaken in collaboration with the Butterfly Conservation Trust. Initial survey results show successful breeding of the dingy skipper in areas where translocation was undertaken in 2013.

A poster describing the project will be on display at the CIEEM Autumn conference in Edinburgh on 11th and 12th November 2014.  A copy of the poster will be available to download soon.
