2 State Nature 2016 Results look up tables This document presents tables the results referred to in the report in an easy to access format. All data presented here feature in the report in the text or graphics. For full details the methods and how these measures were calculated, as well as caveats around interpretation, please refer to pages the report. Details the datasets behind our analyses, our data sources and the species they covered, are given online at rspb.org.uk/statenature

3 TABLE 1. Categories : Each species was placed into one five trend categories based on annual percentage s, overall results reported include the breakdown by: (i) the declining and the increasing, and by (ii) the species that showed strong erate s, and those showing little, in each time period.

Change over time: These results use abundance data (based on a species population size) and occupancy data (the proportion 1-km2 grid cells occupied by a species) combined into an indicator to show the in species status over time reported as an annual and an overall 1 Long ( ) Short ( ) species Annual Overall Annual Overall UK 2, Higher taxa Vertebrates Plants & Lichens Invertebrates 1, Habitat Farmland Grassland & heathland Upland Woodland Coastal Freshwater & wetland Urban Marine (all species) Marine (all species excl fish)

8 TABLE 3. Extinction Risk: We summarised the Great Britain Red Lists to present the overall percentage species assessed that are regarded as threatened with extinction from Great Britain (or Ireland) 1. Species considered to be Threatened with extinction include species that have been classified as Critically Endangered, Endangered or Vulnerable in the latest IUCN Red List assessments. Total species species assessed Extinct or threatened 7,964 1, Threatened 7,964 1, Extinct 7, Species threatened with extinction - higher taxa Plants 2, Invertebrates 3, Fungi & Lichens 1, Species threatened with extinction - habitats Farmland 1, Grassland & heathland Upland 1, Woodland Coastal Freshwater & wetland 1, Urban Species threatened with extinction - countries England 6, Northern Ireland 1, Scotland 5, Wales 5, We interpret existing Great Britain Red Lists, based on those species occurring in that habitat or country, with the exception Northern Ireland, where we used all-ireland Red List assessments. 6
