The monitoring forms report the most effective available monitoring techniques for collecting the required parameters and variables, and define operational guidance for data collection. The monitoring forms describe priority variables (e.g. vegetation-plot based analysis) that need to be collected for complying with the Habitat Directive, and also indicate some optional or habitatspecific variables (e.g. substrate condition, water quality, etc.). The activities and methods suggested in this Manual are aimed at enabling the Regions and Autonomous Provinces to implement monitoring activities based on the collection of harmonized data by means of standardized technical protocols. A standardized basis of information is indeed essential for producing comparable data and generating reliable assessments on the conservation status of each habitat type at national level. Some important elements, such as the Favourable Reference Values and optimal thresholds for some of the parameters, are still under discussion at the European level and therefore will need to be further clarified in the near future.

Abstract

The Habitat Directive requires Member States to implement surveillance of the conservation status of habitats and species of Community Interest. The aim of this handbook is to outline the methodological instruments for the implementation of a monitoring program of the Italian habitat types, as required by art. 17 of the Habitats Directive, with particular regard to the data collection at site level. The European guidelines (Evans & Arvela, 2011. Assessment and reporting under Article 17 of the Habitats Directive - Explanatory Notes & Guidelines for the period 2007-2012 -Final Draft. European Topic Centre on Biological Diversity, p. 1-123) require the assessments to be carried out by compiling information on specific parameters and at biogeographical scale. Each parameter is considered separately, eventually combining all parameters in an evaluation matrix thus providing the overall assessment. For each habitat type several parameters have to be considered: “Area”, “Range”, “Structure and Functions”, “Future Prospects”. While “Range” and “Future prospects” need to be assessed only at the biogeographical scale, “Area” and “Structure and functions” can be assessed aggregating data collected at the site level; in this handbook, for each habitat of community interest present in Italy, we present monitoring forms for these two parameters. Altogheter, the handbook contains 124 forms, referring to 10 Coastal and Halophytic Habitats; 11 Coastal Sand Dunes and Continental Dunes, 15 Freshwater Habitats, 5 Temperate Heath and Scrub, 11 Sclerophyllous Scrub (matorral), 15 Natural and Semi-natural Grassland Formations, 8 Raised Bogs and Mires and Fens, 10 Rocky Habitats and Caves, 39 Forests. Each monitoring form has been produced with the support of leading national experts and sent to regional authorities for a review. The monitoring forms report the most effective available monitoring techniques for collecting the required parameters and variables, and define operational guidance for data collection. The monitoring forms describe priority variables (e.g. vegetation-plot based analysis) that need to be collected for complying with the Habitat Directive, and also indicate some optional or habitatspecific variables (e.g. substrate condition, water quality, etc.). The activities and methods suggested in this Manual are aimed at enabling the Regions and Autonomous Provinces to implement monitoring activities based on the collection of harmonized data by means of standardized technical protocols. A standardized basis of information is indeed essential for producing comparable data and generating reliable assessments on the conservation status of each habitat type at national level. Some important elements, such as the Favourable Reference Values and optimal thresholds for some of the parameters, are still under discussion at the European level and therefore will need to be further clarified in the near future.
