Field Recording and Bioindicators
Field recording is a foundation for understanding the status of species in the landscape. Our work identifies robust methods for data collection and interpretation, while providing opportunities at all levels to enjoy fieldwork and contribute valuable scientific data.
Our work bridges between the complexity of analysing ad hoc field data, often collected by species experts (with taxonomic quality, but statistically problematic), through to public participation data (taxonomically limited, but statistically controlled), especially through the use of indicator species.
First, we undertake ecological analysis to improve the collection and interpretation of field data (Ellis & Coppins 2017). Second, we analyse distributional data to statistically test for and identify environmental indicators and metrics: (i) for Britain's temperate rainforest (Ellis, 2014) and (ii) for species associated with 'old-growth' properties, i.e. long ecological continuity (Whittet & Ellis 2012; Ellis 2015). Third, we analyse community-scale data to create new robust classifications and indicators used for monitoring the quality of lichen-rich habitats, including epiphyte status in Scotland's woodlands (Ellis et al. 2015).

Good to Know
Everyone can contribute useful record data for lichens; our trend analysis for rare and threatened lichens is calibrated against the changing number of records for common species. Records for common and easily identified species are therefore a vital part of biodiversity information!
