Starting principles Actions we can start now – not requiring new policy or legislation No regrets – they would be good things to do even if we did not face climate change Set the direction of change not the final destination
The Guidelines (page 10-11) 1 Conserve existing biodiversity 1a Conserve Protected Areas and other high quality habitats 1b Conserve range and ecological variability of habitats and species 2 Reduce sources of harm not linked to climate 3 Develop ecologically resilient and varied landscapes 3a Conserve and enhance local variation within sites and habitats 3b Make space for the natural development of rivers and coasts 4 Establish ecological networks through habitat protection, restoration and creation 5 Make sound decisions based on analysis 5a Thoroughly analyse causes of change 5b Respond to changing conservation priorities 6 Integrate adaptation and mitigation measures into conservation management, planning and practice
Guideline 1a. Conserve Protected Areas and other high quality habitats. Change to protected area and other high quality wildlife habitat will occur. Managed properly these areas will continue to support higher diversity than the surrounding countryside. Significant and important uplands occur outside areas designated for biodiversity conservation. Mountain ringlet Sites of Special Scientific Interest Adonis blue butterfly

Habitat Networks 100 Largest habitat networks in England for heathland, woodland and mire, fen and bog. Grey areas indicate large urban settlements.
Why take a landscape-scale approach? • It is not just about climate change. • Plant and animal communities are not closed systems – there is continuing species turn over – species conservation goals should be set at landscape and regional species pool level. • Many species “populations” are naturally dynamic e.g. open populations, meta-populations, shifting cloud, etc. • Many habitats, and their associated species, are naturally components of dynamic landscapes e.g. scrub, riverine habitats, many standing waters and wetlands, most coastal habitats. • Historic environment, geology and people’s enjoyment of the countryside are best understood at a landscape scal • If we are to solve the problems of the freshwater environment we will need to work at catchment scale.
What does an integrated approach look like? SSSIs, SACs, SPAs, AONBs and National Parks in England Netherlands Ecological Network
