Definition of Marine biological valuation:
The intrinsic value of marine biodiversity, without reference to anthropogenic use (Derous et al. 2007a) [1].
This is the common definition for Marine biological valuation, other definitions can be discussed in the article


Development of biological valuation approaches

Current attempts to valuate nature are based largely on two papers published by Costanza et al. (1997) [2] and Costanza (1999) [3], which set forth the foundation for assessing the value of environmental goods and services in monetary terms. However, challenges to purely economic valuations of nature were soon recognized [4]. A concept for biological valuation in the marine environment was developed by Derous et al. (2007a), based on an international workshop held in 2004 and an extensive literature review [1]. The concept was further refined based on an ENCORA and MarBEF workshop held in 2006 [5]. The purpose of marine biological valuation is to assess the intrinsic biological value of marine areas and their subzones. This can be done on a continuous or discrete value scale, e.g. high, medium and low value [1].

Biological valuation methodology

The marine biological valuation methodology is able to integrate all available biological information on an area into one indicator. This methodology can be used in every marine environment, regardless of the amount and quality of the available biological data or the habitat type. It yields relative results that allow comparisons between subzones within a study site, but no absolute values that could be used to compare different study areas [6]. In contrast to many other approaches, no single measures of biodiversity (such as species richness or occurrence of flagship or keystone species) are used in this methodology, as these would not reflect total biodiversity or would not adequately mirror the complex marine biological systems Cite error: Invalid <ref> tag; refs with no name must have content [1]. In the original methodology, five valuation criteria were selected [1] . The three first-order criteria were rarity, aggregation and fitness consequences. In addition, the two modifying criteria naturalness and proportional importance were included. After a first application of this method to the Belgian North Sea coast [7], the concept was refined in the ENCORA and MarBEF workshop mentioned before [5]. To avoid double counting, the two criteria aggregation and fitness consequences were combined in the new methodology. Moreover, the criteria of proportional importance and naturalness were excluded. The use of rarity as a valuation criteria remained unchanged in the refined method [5].

Are all species equal?

This approach was developed for the establishment of the best criteria for delineating marine protected areas. Since any kind of valuation requires ranking selected objects as more or less valuable, it raises ethical and philosophical questions, namely, whether all species are equal or not. Some recent studies discuss this dilemma, including Linder (1988)[8], Singer (1989), Schmidtz (2002)[9], and Jennings (2009)[10]. Although it is accepted that all species are equal in moral terms, their contributions to ecosystem structure and function differ, and this can be assessed in scientific terms. Phylogenetic relationships can also be taken into account when considering biological value: so has a species that is one of hundreds in a single genus a lower importance for conservation than a species that is the only one in its order.

Biological valuation maps

Marine biological valuation is a tool for calling attention to subzones that have particularly high ecological or biological significance. Biological valuation maps can therefore be used as baseline maps for future spatial planning in the marine environment [1].

Biological valuation maps of areas located near three main harbours at the Belgian coastal zone: (a) Nieuwpoort (Lombardsijde); (b) Oostende (Oostende-East); (c) Zeebrugge (Baai van Heist). The subtidal and intertidal parts of the subzones were assessed separately. (Vanden Eede et al. 2014) [11].

Biological value is not a direct measure of ecosystem health, although areas regarded as of high biological value are often considered to be valuable providers of socio-economic goods and services and are of high quality in terms of environmental health. The main difference is, however, that biological valuation focuses on the features of species and communities themselves, and not on the contamination or the extractable/usable part of the ecosystem.

Therefore marine biological valuation provides a comprehensive concept for assessing the intrinsic value of the subzones within a study area. It is a tool for calling attention to subzones that have particularly high ecological or biological significance. The biological valuation maps can also be used as baseline maps for future spatial planning in the marine environment. [12]

Recent use of the biological valuation approach

After its initial development in 2007, the biological valuation method was applied in Belgium, Portugal, Poland, the UK and Denmark. Only few case studies can be found in online publications that used this methodology after 2009. At the Bay of Biscay in the Basque continental shelf, a biological valuation map was created and used to identify biodiversity hotspots in 2011 [6]. Moreover, Vanden Eede et al. (2014) [11] continued the biological valuation of the Belgian North Sea coast, this time based on an R-script developed by the Flanders Marine Institute (VLIZ).

Biological valuation vs. ecosystem service assessments

An alternative method to valuate nature is the ecosystem service concept, which has gained strong momentum and popularity over the past 20 years [13]. Ecosystem services are commonly defined as “the benefits people obtain from ecosystems” [14] or “the direct and indirect contributions of ecosystems to human well-being” [15]. In contrast to the biological valuation method, which does not incorporate anthropogenic use, ecosystem services are therefore completely anthropocentric. In coastal and marine environments, the valuation of ecosystem services has become increasingly important [16]. Ecosystem service assessments are recognized to have a high potential for applications in marine spatial planning [17] or integrated coastal zone management[18]. For example, a nation-wide assessment of coastal and marine ecosystem services was recently conducted in the UK, with the aim to contribute to a decision support system for adaptive coastal management [19]. One reason why the biological valuation method is not as often applied in decision-making contexts might be that a purely biological valuation is by definition not suitable to assess impacts of human management: "Biological valuation maps give no information on the potential impacts that any human activity could have on a certain subzone, since criteria like vulnerability and resilience are deliberately not included in the valuation scheme...". (Derous et al. 2007a) [1]. Further non-biological assessments are required to allow the use of biological valuation maps as decision-support tools for marine or coastal management.
