3 1. Introduction This document provides further details and guidelines for the database named Restoration_2015 (downloadable from the EEA website) which provides the accompanying data for the report named Restoration efforts required for achieving the objectives of the Birds and Habitats Directives. In the following sections, each table in the database and its fields within are described in greater detail than that provided in the database file itself Brief background to the associated report The associated report Restoration efforts required for achieving the objectives of the Birds and Habitats Directives intends to provide a review of 1) the restoration needs for habitat types and species listed in the Nature Directives and 2) of the restoration objectives that EU Member States have set, as well as 3) to give an understanding of the nature and appropriateness of restoration efforts envisaged by EU Member States Compatibility The database is built in Microsoft Access, and should be compatible with all versions of Access after and including versions. 4

4 2. Restoration needs tables The following two tables provide further information regarding datasets derived from Art. 17 data to quantify habitat restoration, and species recovery needs across the European Union. Each row of data shows the habitat or species per country, per biogeographical region. This level of data is known as an assessment (a row). All columns are taken from the Art. 17 database, unless otherwise stated. For further information see the Art 17 Explanatory Notes & Guidelines for the period Habitat restoration needs per country and biogeographical region Number of columns 17 Number of rows Table structure Column heading Data type Short description ID Number Unique identifier Country 2-letter ISO country code Marine or terrestrial Whether the habitat type is marine or terrestrial according to biogeographical region Biogeographical region Biogeographical region to which the need apply Habitat code Code for the habitat type (as in Art. 17 reporting) Habitat name Habitat type name (as in Art. 17 reporting) Habitat group Habitat group to which the habitat type belongs (as in Art. 17 reporting) Priority habitat Yes/no Whether the habitat is an EU priority Current area Number Current surface area in km² Structure and functions Conclusion on structure and functions FRA value Number Favourable Reference Area in km² FRA operator Operator used where FRA value is not available Restoration need Number Calculated from FRA and current area Area in Natura min Number Minimum area in Natura 2000 (in km 2 ) Area in Natura max Number Maximum area in Natura 2000 (in km 2 ) Data sources Published data source URL URL The dataset in Art. 17 had 3032 assessments. The table below shows which of these were excluded from the final table resulting in 2772 assessments. 5

5 Number of individual assessments Total number of individual habitat type assessments from Article (assessments per country and per biogeographical region) Excluding assessments where the current area was missing 226 Excluding assessments where the FRA was quantified but smaller 12 than current area Excluding assessments where the < operator was used 22 Total on which analysis is based 2772 (91% of 3032) See report for further details ID Unique identifier for each row of data. These ID s do not correspond with those in the Art. 17 database Country The country code as given under the Habitats Directive (ISO two digit country code). Each country is identified in the table below. Country Country Code Country Country code Austria AT Latvia LV Belgium BE Lithuania LT Bulgaria BG Luxembourg LU Cyprus CY Malta MT Czech Republic CZ Netherlands NL Denmark DK Poland PL Estonia EE Portugal PT Finland FI Romania RO France FR Slovakia SK Germany DE Slovenia SI Hungary HU Spain ES Ireland IE Sweden SE Italy IT United Kingdom UK In the Art. 17 database this column is called country Marine or terrestrial Whether in a terrestrial or marine habitat. This is determined by the biogeographical region. See below. This column is not found in the Art. 17 database Biogeographical region The biogeographical region of the habitat type as given under the Habitats Directive. See table below for definitions. Those with a four letter code starting with M are marine. All others are terrestrial. 6

6 Region code TERRESTRIAL ALP ATL BLS BOR CON MAC MED PAN STE Region name Alpine Atlantic Black Sea Boreal Continental Macaronesia Mediterranean Pannonian Steppic MARINE MATL MBAL MBLS MMAC MMED In the Art. 17 database this column is called region. Atlantic Baltic Black Sea Macaronesia Mediterranean Habitat code and Habitat group The habitat code as given in the Habitats Directive. The table below shows the nine habitat groups and their single digit code prefix (1, 2, 3 9). For all of the habitat names, see the database and associated report. Habitat code prefix Habitat group 1 Coastal habitats 2 Dunes habitats 3 Freshwater habitats 4 Heath and scrub 5 Sclerophyllous scrub 6 Grasslands 7 Bogs, mires and fens 8 Rocky habitats 9 Forests In the Art. 17 database, the Habitat code column is called habitatcode, and the Habitat group column is called habitatgroup Habitat name The full name of the habitat type as given under the Habitats Directive. 7

7 In the Art. 17 database this column is called habitatname Priority habitat Whether the habitat is an EU priority habitat as defined in the Habitats Directive. Priority habitats have a tick (), YES, or TRUE depending on the version of Microsoft Access being used to view the data. Non-priority habitats are left blank. In the Art. 17 database this column is called annex_priority Current area Current total surface area in (km 2 ) of that habitat, in that country per biogeographical region. Where the current area is unknown, this column is left blank. These unknown area assessments are not used in the calculations of restoration needs. In the Art. 17 database this column is called coverage_surface_area Structure and functions This column is used to calculate improvement needs. Structures and functions are combined to provide an overall assessment of the condition of a given habitat. Structures are considered to be the physical components of a habitat type; these will often be formed by species. Functions are the ecological processes occurring at a number of temporal and spatial scales and vary greatly between habitat types. For a habitat type to be considered to have a Favourable Conservation Status the Directive requires its structure and functions to be favourable and its typical species to be at Favourable Conservation Status. Three classes are used to describe the structure and functions of a habitat: FV: Favourable U1: Unfavourable - inadequate U2: Unfavourable - bad In some cases the structure and functions are unknown. In these cases the column is left blank, and improvements needs cannot be quantified for these assessments. In the Art. 17 database this column is called conclusion_structure FRA value This column is used to calculate restoration needs. The FRA refers to the Favourable Reference Area. This is the total surface area in a given habitat and country per biogeographical region which is considered the minimum necessary to ensure the long-term viability of the habitat type. See the Art 17. Explanatory Notes & Guidelines for the period for further information. The FRA is reported as a value in km 2. However if the value is unknown then this column is left blank, and where possible an operator is given instead (see below). In the Art. 17 database this column is called complementary_favourable_area FRA operator This column is used to calculate restoration needs. Operators are used where it is not possible to estimate a value for FRA, but the FRA can be broadly categorised into one of four classes via 8

8 expert judgement. These operators give an indication of what is needed for the parameter to be favourable. The operators are: >: Greater than >>: Much greater than <: Less than : approximately equal to See section for how these operators were converted into area estimates. In some cases both the FRA operator and the FRA value are unknown. In these cases both columns are blank, and area based restoration needs cannot be calculated. In the Art. 17 database this column is called complementary_favourable_area_op Restoration need Where an FRA value is given, restoration (additional area) needs are calculated as the difference between the FRA and the current area, and this value is provided in this column. Where an FRA operator is given instead these area converted into numerical values using the following method: Where the operator is reported, the FRA is assumed to be the same as the current area. So the restoration need is zero. Where the > and >> operators area reported, these operators area converted into quantified FRA values based on the following criteria: o o For >>, a conservative 10% increase is applied to the current area, based on Article 17 guidelines which state that Expert judgement will be required to determine if the operator should be > or >>. If the operator is >>, the current value is very likely to be more than 10% below FRV. For the operator >, it is assumed that the increase to the current area must lie between 0 and 10%. As there are no specific guidelines for this operator in the Article 17 Guidelines, the proportional increase for > was calculated as the median percentage increase (3.7%) of the subset of individual assessments where the FRA is given as an exact figure that ranges between 0% and 10%. Where both the FRA value and the FRA operator are missing, the restoration need is left blank. This column is not found in the Art. 17 database. Rather it is calculated as described above Area in Natura 2000 min, and Area in Natura max Area in Natura 2000 min provides the estimated minimum area of the habitat type in the assessment which falls within the Natura 2000 network. Area in Natura 2000 max provides the estimated maximum area of the habitat type in the assessment which falls within the Natura 2000 network. Where the minimum and maximum areas are the same, this means that the value is known exactly rather than estimated. In the Art. 17 database these columns are called natura2000_area_min and area in Natura 2000 max respectfully. 9

Where an FRP operator was reported in Art. 17, that is given here, where an FRP value was reported, that was converted into an operator (see below) Data sources Published data source URL URL The dataset in Art. 17 had 7122 assessments. The table below shows which of these were excluded from the final table resulting in 6910 assessments. Number of individual assessments Total number of individual species populations assessments from Art (assessments per MS and per biogeographical region) Minus the assessments where FRP the < operator was used 113 Minus the assessments where the FRP was given as a numerical value but smaller than the current minimum population 99 Total on which the analysis was based See report for further details (97% of 7122) 11

11 2.2.2 ID Unique identifier for each row of data. These ID s do not correspond with those in the Art. 17 database Country The country code as given under the Habitats Directive (ISO two digit country code). See section In the Art. 17 database this column is called country Biogeographical region The biogeographical region of the species given under the Habitats Directive. See section for definitions. Those with a four letter code starting with M are marine. All others are terrestrial. In the Art. 17 database this column is called region Species code The 4-digit species code as given under the Habitats Directive. In the Art. 17 database this column is called speciescode Species name The full name of the species as given under the Habitats Directive. In the Art. 17 database this column is called speciesname Taxa The taxonomic group as given under the Habitats Directive. In the Art. 17 database this column is called tax_group Priority species Whether the species is an EU priority as defined in the Habitats Directive. Priority species have a tick (), YES, or TRUE depending on the version of Microsoft Access being used to view the data. Non-priority species are left blank. In the Art. 17 database this column is called annex_priority Annex II, Annex IV, Annex V Which annexes of the Habitats Directive the species is listed on. Y = species is listed in the Annex; Y-HTL = species implicit listed in the Annex via a higher taxonomic level; Y-CTC = species is covered by the Annex, difference in scientific name is due to a change in taxon concept (e.g. because previous species concept has been revised and split up in two species); Y-EXCP = species is listed in the Annex with regional exceptions; N = species is not listed in the Annex. In the Art. 17 database these columns are called annex_ii, annex_iv and annex_v. 12

12 Population minimum size and Population maximum size Population minimum size and Population maximum size provide estimates of the total population size of that species within that country and biogeographical region. In the Art. 17 database these columns are called population_minimum_size and population_maximum_size Population size date Provides the year of the population size estimate. In the Art. 17 database this column is called population_date Population size unit Provides the unit in which the population was assessed. i=individuals. In the Art. 17 database this column is called population_size_unit FRP value This column is used to assess recovery needs. The FRP refers to the Favourable Reference Population. This is the total population of a given species in a country per biogeographical region which is considered the minimum necessary to ensure the long-term viability of the species. See the Art 17. Explanatory Notes & Guidelines for the period for further information. The FRP value is reported as a value in relation to the population size unit. However if the value is unknown then this column is left blank, and where possible an operator is given instead (see below). In the Art. 17 database this column is called complementary_favourable_population Recovery need value Where an FRP value is given, population recovery needs are calculated as the difference between the FRP and the minimum population size. These data are not used in the analysis of the associated report per se, they are converted into a recovery need operator (see below). This column is not found in Art Recovery need operator This column is a combination of the operators reported in Art. 17 (in the column named complementary_favourable_population_op of the Art. 17 database), and, where an FRP value is reported, new operators calculated from that FRP value. This values are converted using the following criteria: Where the FRP value is equal to the population minimum size, these are given. Where the FRP value is between zero and 25% greater than the population minimum size, these are given >. Where the FRP value is between greater than 25% more than the population minimum size, these are given >>. 13
