<P align=justify><SPAN lang=en-gb><FONT face=Tahoma>The biological communities
of small streams and springs are distinctive, and more than simply a nested
subset of species found downstream. Springs are considered special habitats by
all running water classification systems in recognition of their marked
environmental stability and generally low degree of pollution. They are however
much less studied than other freshwater habitats. The processes that provide
habitat conditions suitable for specialized taxa have often only been described
in general terms. Advances in testing physical, chemical and biological
mechanisms that select amongst taxa have started to demonstrate the roles of
hydraulic and other physical processes that set habitat constraints. As applied
problems emerge, it is increasingly important to strengthen fundamental
knowledge on these environments. Indeed, springs and groundwater-fed streams are
often under-protected in some landscapes (e.g. managed forests), while in others
they are increasingly threatened by capture for drinking water use (European
Alps). This session will explore the distinctiveness of the biological and
physical systems, as well as how these are affected by various kinds of
management. The links (or absence thereof) to broader policy, such as the Clean
Water Act (USA) and the Water Framework Directive (EU-WFD) will also be
considered. Initiatives for an improved international cooperation in
spring-research will be explored.</FONT></SPAN></P>
