Dear Hans et al., dear All,
First of all, I would like to thank Hans et al. for the very nice
synthesis work they did and links to interesting recent literature. I
fully agree that conservation should become more and more
scientifically grounded to allow biodiversity to resist/adapt to the
increasing pressure from multiple driving forces. Please note that
bridging the gap between theory and practice was the core element
discussed in details during a European (EPBRS) electronic conference
organised by the Platform in November-December 2001 (Biodiversity
Conservation in theory and practice) (see Segers et al. 2001).
Though I agree with most of the text, I'm not fully convinced by the
very last paragraph. I'm not sure that increasing social pressures in
a climate change context will necessarily conflict with biodiversity
conservation issues. What I heard from Patrick Meire about the
restoration of Scheldt wetlands as climatic buffer areas is more a win-
win situation for biodiversity and climate than diverging options.
Urban forests are a typical example where social pressure can lead to
a decrease in the demand for wood products and favour conservation
goals (see e.g. Zoniënwoud). I would advice to adopt a more balanced
opinion here.
I agree with the substantial comment by Erik. It can be asked, for
example, if the static conservation targets of Natura 2000 are really
an adequate way to make nature conservation in a climate change
context. For example, the principle to consider the different phases
of ecological successions as independent and fixed conservation units
is probably not the best way to cope with climate change. We need
probably more flexibility here. Maybe something that can be developed
a little bit in part II or IV of the text.
At last, I would like to make another substantial comment (sic). What
would you think to present in part IV responses that should be
developed for biodiversity conservation for two different climatic
scenarios? Scenario 1 would consider answers to weak environmental
changes that do not necessarily lead to massive species migrations. In
that case, conservation should focus on improving ecosystem resistance/
resilience, the preservation of biodiversity hotspots, etc. With a
focus on "climatically trapped systems" like boreo-alpine, peatbogs,
etc. Scenario 2 would consider answers to be given to strong changes,
e.g. migration and connectivity issues, permeable landscapes,
ecosystem capacity to accommodate southern species, etc. Just a
thought... Something that can be illustrated through an example for a
given ecosystem type. Considering peatbogs, for example, it would be
nice to present concrete measures that can be proposed to managers.
Best regards,
Etienne Branquart
