Objective: Analyses and evaluation of the biodiversity indicator “quantity and scale of nature reserves in a country“
Learning outcomes: By example of the indicator “quantity and scale of nature reserves in a country“ the students will be able to analyse biodiversity indicators and evaluate their significance in ascertaining the biological diversity.
Previous knowledge: The students need to know what biodiversity monitoring is and know the quality criteria for biodiversity indicators.

Learning subject: Biodiversity / Module 2: Biodiversity and environmental protection / Level: expert learning
There are many possible indicators for implementing a biodiversity monitoring program in a country, for example the distribution of selected species, water quality, domestic animals, scale of ecosystems in a region, investments in biological diversity, etc. In this learning unit we will deal with the exemplary biodiversity indicator “quantity and scale of nature reserves in a country“.
Nature reserves are an important instrument in sustaining the biological diversity. Reporting the number of protected areas on various scales is conducted nationally in each country (comp. i.e. http://www.areasprotegidas.gov.cv). This is also the reason why the indicator “quantity and scale of nature reserves in a country“ is recognised globally.
Research the internet for the biodiversity indicator “quantity and scale of nature reserves in a country“ and answer the following questions:
1. Does the indicator measure things of importance to people and is it of relevance in respect to biological diversity?
2. What are the key factors for this indicator?
3. What kind of data is available for this indicator?
4. What are the limits of this indicator?
5. Is it possible to aggregate individual elements of this indicator?
6. Does this indicator overlap or intersect with other indicators?
7. Can the data for this indicator be acquired cost-efficiently?

Possible results / Results:
1. The number of nature reserves is an easy concept to understand and integrated into the every day life of the people. Therefore it is very suitable for use in public relations. Also the political dimension of biodiversity is addressed directly.
2. A decisive factor for nature reserves is competition in land use: agriculture, urbanisation, infrastructure, tourism, …
3. Relevant data exists on nearly all scales.
4. Varying definitions of nature reserves and protected areas; interpretation depends on the associated objectives; administration can be difficult.
5. Yes it is possible to aggregate individual elements of the indicator. For example, the quantity and size can easily be aggregated on different scales.
6. The indicator not only complements other indicators, but it is partially essential for the interpretation of other indicators.
7. The indicator is relatively cost-efficient because the data is already available and does not have to be collected from nothing.
