Abstract Distribution maps of cetaceans and seabirds at basin monthly scales are needed for conservation marine management. These usually created from standardized systematic aerial vessel surveys, with recorded animal densities interpolated across study areas. However, distribution have previously not been possible because individual surveys restricted spatial temporal coverage. This develops an alternative approach consisting of: (a) collating diverse survey data to maximize coverage, (b)...
Assessments of the impact offshore energy developments are constrained because it is not known whether fine-scale behavioural responses to noise lead broader-scale displacement protected small cetaceans. We used passive acoustic monitoring and digital aerial surveys study changes in occurrence harbour porpoises across a 2000 km 2 area during commercial two-dimensional seismic survey North Sea. Acoustic visual data provided evidence group airgun from 470 cu inch array over ranges 5–10 km, at...
We present a Geographic Information System (GIS) tool, SeaMaST (Seabird Mapping and Sensitivity Tool), to provide evidence on the use of sea areas by seabirds inshore waterbirds in English territorial waters, mapping their relative sensitivity offshore wind farms. is freely available source for all connected industry will assist statutory agencies assessing potential risks seabird populations from planned developments. Data were compiled boat aerial observer surveys spanning period...
Summary Robust estimates of the density or abundance cetaceans are required to support a wide range ecological studies and inform management decisions. Considerable effort has been put into development line‐transect sampling techniques obtain absolute from aerial‐ boat‐based visual surveys. Surveys using acoustic loggers digital cameras provide alternative methods estimate relative that have potential reduce cost verifiable record all detections. However, ability these reliable yet be...
Growing concerns about climate change and energy security have fuelled a rapid increase in the development of offshore marine renewable installations (OMREIs). The potential ecological consequences increased use these devices emphasises need for high quality environmental impact assessment (EIA). We demonstrate that processes are hampered severely, primarily because legislation does not ensure significance impacts cumulative effects properly assessed. highlight why regulatory framework leads...
Abstract Widely available ‘fish‐finder’ echo‐sounding devices are beginning to be used in bathymetric studies estimate geomorphic change. To date, however, there have been no applications shallow and complex wetlands, where changes sediment storage notoriously dynamic time difficult describe accurately space. Therefore, this study, we tested the performance of an ‘off‐the‐shelf’ fish‐finder for mapping bathymetry a beaver pond. We sonar depth readings against traditional‐sounding lead‐line...
In common with many European streams, most streams in south-west England have failed to reach Good Ecological Status under the Water Framework Directive. The landscape comprises mainly pastoral and arable fields, from which rainwater can run off, carrying huge quantities of sediment surplus fertiliser. receiving often highly modified through channelisation, are degraded physical, chemical biological effects these pollutant loads, notably high nutrient fine inputs leading...
Abstract Individual animals are often given names by humans. For example, attributed to domestic acknowledge their closeness people, some research studies use identify differences between individuals in a study group, or zoos tell stories that attract public media attention. Publicly naming individual can provide opportunities conservation, but there also risks. In this perspective we exemplify such and risks the context of wildlife reintroductions. We draw on examples observations from our...
Atlantic Puffins Fratercula arctica were counted at all known colonies in Orkney (excluding Sule Skerry) during the 2016 breeding season. Counts of individuals (IND) made pre-laying and incubation 20 sites six where burrows physically accessible. In Puffin population was estimated to be 6,675 pairs (based on counts apparently occupied [AOB] available, assuming that one individual represented pair for other sites). AOB higher than IND both methods used. Previous estimates mostly based land...
