  1. Data resource: 1921 Onwards Occupied Swift Nests, UK

    The dataset is intended to be a comprehensive inventory of occupied common swift (Apus apus) nests (where swifts were observed using a nest site cavity). It includes records collected as part of various swift mapping projects including The Swift Inventory, The Swift Survey and The Swift Mapper. The aim of these projects was to better understand the reasons for the decline in swifts in the UK, and to help target conservation of swift nest sites. They collated data from a variety of sources, primarily a public request for information and local surveys. Between 2009-2015, records were collected as part of the ‘Swift Inventory’. This was a cooperative project involving the support of Concern for Swifts - Scotland, London's Swifts, Northern Ireland Swifts, the RSPB, Swift Conservation and UK Swifts. The ‘Swift Survey’ then ran from 2016 -2019. This was a national survey, including a website developed by Environmental Resource Management (ERM) to collect data from the public on nesting swifts. From 2020 onwards the ‘Swift Mapper’ tool has been used to collect records. The Swift Mapper is a mapping tool involving RSPB, Natural Apptitude, Swift Conservation, Action for Swifts and Swifts Local Network. Records prior to 2009 were provided by swift conservation groups and RSPB surveys. Accompanying datasets of nest boxes, previously occupied nests and low-level screaming swifts (probable breeders) are also available on the NBN. This dataset will be updated annually.

  2. Data resource: 1921 Onwards Swift Screaming Parties, UK

    This dataset contains reports of common swifts (Apus apus) flying at rooftop level, calling with their characteristic screaming sound. This behaviour indicates that swifts are probably nesting nearby. It includes records collected as part of various swift mapping projects including The Swift Inventory, The Swift Survey and The Swift Mapper. The aim of these projects was to better understand the reasons for the decline in swifts in the UK, and to help target conservation of swift nest sites. They collated data from a variety of sources, primarily a public request for information and local surveys. Between 2009-2015, records were collected as part of the ‘Swift Inventory’. This was a cooperative project involving the support of Concern for Swifts - Scotland, London's Swifts, Northern Ireland Swifts, the RSPB, Swift Conservation and UK Swifts.

  7. Data resource: 1960-1970 Barnes, RSK and Coughlan, J Blackwater Estuary Bottom Fauna Dredge Survey - Version 2.2

    A number of additions and corrections are made to the Blackwater Estuary fauna list. Distribution patterns revealed by a survey of the benthic fauna of the Blackwater Estuary in May 1970 are described, and changes in the frequency of occurrence of a number of species between 1960 and 1970 are discussed. It is concluded that the fauna of the region has, to a large extent, recovered from the severe winters of 1961-62 and 1962-63.

  8. Data resource: 1966-1986 T.G. Skinner Solway Firth Occurrence of some prominent zooplankton

    Three surveys were carried out by T.G. Skinner in the Solway Firth Areas. Surveys were carried out with plankton nets and a count of the species captured were carried out. This is the first survey: Observation on Solway Hydromedusae (Glasg. Nat. 19: 189-197 (1975)). Three surveys were carried out by T.G. Skinner in the Solway Firth Areas.

  11. Data resource: 1984 Farnham and Bishop St Mawes Fal Estuary Cornwall Maerl dive transect survey

    A voluntary marine conservation area has been declared in the Roseland district, which includes a maerl bed (St Mawes Bank) of considerable scientific interest because it is the only significantly sized bed of live maerl in southern England. This report provides a baseline survey of this conservation area. Starting in 1982, initial spot dives were carried out at different times of the year in order to obtain information on the distribution of maerl. Subsequently two transect lines were laid from a boat across the width of the bed (800m) from the shore towards the Vilt Buoy.

  12. Data resource: 1984 University of Virginia Cornwall foraminifera and meiofauna on an intertidal mudflat core survey
