Natural England (2017). Species Surveillance Project - Rare Priority Species on Natural England NNRs. Occurrence dataset https://doi.org/10.15468/lsanac accessed via GBIF.org on 2024-10-02.Description
Records of a selection of rare species from NERC Act s41 list and /or Habitats Directive Annexes, captured by Natural England staff and volunteers on NNRs managed by Natural England. Includes both historical data from NNR records and current data from recent and ongoing surveys. This Project forms part of Natural England's Evidence Programme.Purpose
Surveillance of these species on our NNRs is a direct contribution to our ability to understand the status and trends of some of England's rarest and most threatened species, and therefore supports Outcome 3 of the Biodiversity 2020 Strategy. The data also supports the need to understand population status and trends on these individual NNRs, in order to formulate appropriate management and help understand its impact.Sampling Description
Quality Control
Confidence in identification is generally high, as surveyors are generally NNR site staff and selected volunteers with training in the species concerned, and records are verified within iRecord before transfer to NBN Gateway. Some internal QA is also performed to improve consistency of certain attributes.Method steps
- Historical records were captured by trawling through catalogued NNR sources including unpublished surveys. Current survey methods are varied, reflecting lack of knowledge about some species ecology and the difficulties of locating or counting some of them. Most methods are still under development, but generally involve a seach of suitable habitat on the site, focussing on previously recorded locations. Where possible an estimate of abundance and distribution on the site is attempted, so some methods include sampling where the species is locally abundant. Site staff and volunteers in most cases had the required expertise to identify species confidently, or sought expert assistance. Records were captured on, and are actively managed within, iRecord via the NE NNR Priority Species Surveys form, and those records validated online transferred to the NBN Gateway.
Taxonomic Coverages
Geographic Coverages
Surveys are carried out on up to 142 NNRs in England, managed directly by Natural England staff. Sites covered depend on our understanding of which rare priority species occur on which NNRs. Location precision of records varies from 1m (GPS) to six-figure grid references (100m). Historical records are similarly compiled from up to 142 NE-managed NNRs.
