Methodology:

Selection and methodology of indicator’s assessment is based on the set of indicators proposed by the OECD and addressed by the report: "Green Growth: Monitoring progress towards green growth“. Data relating to the national situation are usually presented in the period between 2000 and 2012. Basic time sequence is changed in those cases when the data are not accessible or when their comparison is not possible due to differing approaches in their collection, assessment, changes in methodology, classification, etc.  Summary assessment of indicator’s trend from the green growth perspective is based on a subjective evaluation of the responsible assessor due to the fact that the strategy is not officially implemented in the Slovak Republic and therefore specific objectives have not been defined.  Naturally, this assessment builds on the analysis of the past trends, as well as their anticipated direction in view of the measures adopted as to date.
Selected indicators characterize Slovakia's initial position as seen from the perspective of the green growth and were to be used as a measuring tool before further steps are taken in the process of implementation of this strategy and for a complex assessment of the future trend of the Slovak economy.  Present set of green growth indicators comprises 32 individual indicators that are relevant in Slovakia's conditions. Four of them are national indicators that describe voluntary instruments of the environmental strategy.

 

Data sources:

Data used in this document come from the official national or international sources and databases. Assessed trend was reviewed and discussed with the state administration specialists (individual departments of the ministries of Environment, Economy, Labour and Social Affairs and Family, Finance, Agriculture and Rural Development) and their professional organisations (Slovak Hydrometeorological Institute, State Geological Institute of Dionýz Štúr, Slovak Environmnet Agency, State Nature Consservancy, Institute for Financial Policy) and also the Statistical Office of the Slovak Republic whose databases furnish most of the information.

Kľúčové zistenia

More than 25 % of original plant species in Slovakia belong to endangered species. Most of the critically endangered species of the Slovak flora come from habitats that are globally endangered in the whole of Central Europe (peatbogs, wetlands, flooded meadows, salt lakes, sands). Basic cause behind endangering of plant species has been direct or indirect destruction of their habitats. In the case of some species, we still do not know the true causes.

In the 90-ties, then-valid red lists of bryophytes and seed-bearing plants in Slovakia contained 1 009 endangered and rare species (taxa) (40.4 %).
According to red list of ferns and flowering plants in Slovakia from 2015, there are 527 threatened species (14.6 %).

Red list of lower plants that is still valid even today was published in 2001. The list shows 1 047 threatened taxa (13.6 %).

Explanations:
Taxon is a taxonomic unit in the biological system of classification with indeterminate value, for example species, genus, family, and so on.
Data in % indicates the proportion of threatened taxa in the total number of taxa.
Threatened - only species included in IUCN categories CR, EN and VU.
IUCN categories: CR - critically endangered taxon, EN - endangered taxon, VU - vulnerable taxon.
Data per 2016.

Medzinárodné porovnanie

The OECD Green Growth database contains selected indicators for monitoring progress towards green growth to support policy making and inform the public at large. The database provides a synthesis of data and indicators available across a wide range of domains. The sources of the underlying data used to populate the Green Growth Indicators, as presented here, include a range of OECD databases and, in some cases, external data sources. The database covers OECD member countries, accession countries and selected non-OECD countries (including the BRIICS economies - Brazil, Russian Federation, India, Indonesia, China and South Africa).
