habitat loss and degradation in conjunction with other<br />
threats (see sections 3.4 and 3.5). The <strong>European</strong> <strong>Red</strong> <strong>List</strong><br />
has highlighted the fact that 9.2% <strong>of</strong> bees have declining<br />
populations and almost 80% have unknown population<br />
trends (see Figure 12). Special emphasis needs to be<br />
placed on Data Deficient species, especially as some are<br />
suspected to be in a critical state <strong>of</strong> decline at the national<br />
level in some parts <strong>of</strong> the EU and within Europe, but the<br />
lack <strong>of</strong> information from across the whole range or part<br />
<strong>of</strong> the range <strong>of</strong> these species meant that a threat category<br />
could not be assigned. These species should not be<br />
regarded as having Favourable Conservation Status, and<br />
should be the focus <strong>of</strong> further research across the region.<br />
4.5 <strong>Red</strong> <strong>List</strong> versus priority for<br />
conservation action<br />
Assessment <strong>of</strong> extinction risk and setting conservation<br />
priorities are two related but different processes.<br />
Assessment <strong>of</strong> extinction risk, such as the assignment<br />
<strong>of</strong> IUCN <strong>Red</strong> <strong>List</strong> Categories, generally precedes the<br />
setting <strong>of</strong> conservation priorities. The purpose <strong>of</strong> the <strong>Red</strong><br />
<strong>List</strong> categorisation is to produce a relative estimate <strong>of</strong> the<br />
likelihood <strong>of</strong> extinction <strong>of</strong> a taxon. Setting conservation<br />
priorities, on the other hand, normally includes the<br />
assessment <strong>of</strong> extinction risk, but takes also into<br />
account other factors such as ecological, phylogenetic,<br />
historical, economical, or cultural preferences for<br />
some taxa over others, as well as the probability <strong>of</strong><br />
success <strong>of</strong> conservation actions, availability <strong>of</strong> funds or<br />
personnel, cost-effectiveness, and legal frameworks for<br />
the conservation <strong>of</strong> threatened taxa. In the context <strong>of</strong><br />
regional risk assessments, a number <strong>of</strong> additional pieces<br />
<strong>of</strong> information are valuable for setting conservation<br />
priorities. For example, it is important to consider not<br />
only conditions within the region but also the status <strong>of</strong><br />
the taxon from a global perspective and the proportion <strong>of</strong><br />
the global population that occurs within the region. The<br />
decision on how these three variables, as well as the other<br />
factors, are used for establishing conservation priorities is<br />
a matter for the regional authorities to determine.<br />
