Measuring Biodiversity, Lancaster University, Measuring Biodiversity Workshop 16th September 2010 Lancaster Environment Centre ‘ ’ (Magurran 2004). Biodiversity is the variety and abundance of species in a defined unit of study Measuring biodiversity is of course key for formulating policy to protect against biodiversity loss, but is not often considered within the combined contexts of species richness, evenness and density. Policy makers are often interested in change in the rate of change, and whether this is positive or negative. Three guest speakers presented at this Workshop, and informal discussion followed after tea. There were participants from OPAL (Open University & Hedge-link), the Institute for Ecology & Environmental Management, the National Biodiversity Network, the Field Studies Council and the Natural History Museum. Professor Steve Buckland, (Centre for Research into Ecological and Environmental Modelling. St Andrew University) set the scene. Steve presented a synopsis of a key paper (Buckland et al., 2005, Phil. Trans. R. Soc. Lond.) within the context of 2010 target for reducing biodiversity loss by 10%. Key points in the presentation were: why monitor; what should be monitored and how should monitoring be carried out? To address these points, the presentation amalgamated thinking on sampling approach and the features of a robust biodiversity index. A robust index will often be a combination of speciesspecific or survey-specific indices. Always consult a statistician before venturing into the field! Something as simple as the geometric mean can be superior to more complex indices for picking out true long term trends population data & yield the vital information on change in the rate of change. A transfer of approach has to be made from monitoring in a few nonrepresentative pristine sites to monitoring at a variety of representative locations, selected according to some form of random sampling scheme, e.g. a stratified random sample of grid squares. This has been achieved e.g. in the UK Breeding Bird Survey. Achieving this for many taxa, such as invertebrates or reptiles, is more challenging. Linear transects incorporating key habitats within a stratified random sampling grid is one approach. Three main components for a robust index of biodiversity are species richness, evenness and density. A summary of characteristics covered by a good index is summarised in the following 6 points: 1. Species evenness, abundance and density are constant; index should show no trend. 2. Abundance decreasing – index should decrease. 3 .Evenness decreasing –index should decrease. 4. No. of species decreasing – index should decrease. 5. Index should not be a function of sample size 6. It should have good and measureable precision. Lisa Norton (Centre for Ecology & Hydrology, Lancaster) gave a synopsis of the National Countryside Survey (www.countrysidesurvey.org.uk'>www.countrysidesurvey.org.uk). Lisa covered an approach to measuring biodiversity at a National Scale. This national data resource is used heavily by policy makers. It provides the official statistics on stock, condition and change for GB Broad Habitats by surveying the countryside using a randomly stratified sampling design. Lisa covered the sampling methods of the Countryside Survey and their data outputs, spanning three decades of activity. The data – which includes information on habitats, vegetation, soils, headwater streams and latterly ponds is available at www.countrysidesurvey.org.uk'>www.countrysidesurvey.org.uk and can be used for educational purposes. Customised software used during the 2007 survey together with ruggedized computers enabled digital data recording in the field for the first time. The reductions in systematic error and auditable work flows resulted in the most comprehensive and robust data set to date. It was interesting to learn that for the last survey monitoring staff were recruited from Bulgaria in order to reach the full complement of 70 staff that were required for the survey. The staff from Bulgaria had amongst the best botanical skills of all the field survey staff and recruiting sufficient staff from the UK with comparable skills proved difficult. A lack of graduates with taxonomic skills was highlighted in the BBSRC niche skills deficit report published in 2009. Guy Knight (Entomology, Liverpool Museum) gave a timely reminder of the role that museum collections and curators can play as educational resources and sources of taxonomic expertise. Museums undertake consultancy work in monitoring biodiversity, and in managing undergraduate work placements. Jenny Sneddon Liverpool John Moores University. 2010
