Time spent leaning on a five-bar gate is never time wasted (anon.)
The aim of this website is to make available resources that encourage and support biological recorders.
I am very concerned about adverse climate change and the rapid loss of biodiversity.
Biological records are the foundation of evidence based conservation and contain the data needed to protect, restore and enhance biodiversity. I’m an active biological recorder and a multi-skilled, independent field ecologist with an eclectic mix of interests including ornithology, invertebrates and fungi. My skills are based upon more than 20 years of both voluntary and professional work, ranging from otter to veteran tree surveys.
I am particularly interested in technologies that enable the rapid and accurate identification of species and the efficient acquisition of high quality biological records. These include Identikit, digital multi-access taxon identification keys; DNA based biodiversity assessment and soundscape ecology, especially avian bioacoustics.
I wish to play my part in helping us all to understand the changing state of nature.
Precious Woodland Habitat
Bradley Wood is my local patch which I visit on a regular basis. It was given, in perpetuity, to the people of Ashbourne for their enjoyment by Henry Fitzherbert Wright in 1935 and it is managed by Ashbourne Town Council. In order to assess the condition of the woodland and to inform its management, it is essential to accurately record the presence and location of its species on a frequent basis. This should then allow this precious woodland habitat, its immediate surrounds and its species to be protected, cherished and enjoyed by everyone.
One of the largest remaining woodlands in the area, it is on a north facing slope and is dominated by birch, oak and pine. It has a long history of woodland cover and is included on the Ancient Woodland Inventory, is designated a Local Wildlife Site and has considerable nature conservation value. Fungi species richness is a noted feature of interest. In addition, at least five bat species have been recorded as well as nearby lapwing Vanellus vanellus and skylark Alauda arvensis.
Throughout 2021 a range of invertebrate surveys were conducted. Specimens were identified and material sent to a laboratory for DNA analysis. Post comparison of results the DNA sequences will be added to the Barcode of Life Data system (BOLD).

Digital multi-access identification keys
Covers the identification of wader species known to occur in Britain and Ireland on a regular basis. It is part of an integrated suite of wader resources which also includes the Field Studies Council's WildID fold-out guide to Waders of Britain and Ireland and Quizlet Waders of Britain and Ireland.

Gilled Fungi Genera
A collaborative project with Geoffrey Kibby, an experienced mycologist, talented artist and author, this prototype key covers the identification of mature fungal fruit bodies to genus level. It includes over 200 genera known to occur in Britain and Ireland. All have spore producing surfaces in the form of gills (lamellae) on the lower surface of a protective cap (pileus).

This prototype multi-access key covers the identification of flowering plant (angiosperm) specimens to family level. It includes a total of 14 plant families which, between them, contain approximately 67% of the wild British flora.
