If we fail to act decisively to protect migratratory mammals environment many species could be forced to the edge of survival

whats the most effective action plan for protecting migratry mammal speccies over the next 10 years? Should we limit the areas we can help to those areas with the greater chance of success i.e increase the money and resources we target at them and not spread our efforts to thin. Would this give greater success in the long run to preventing extinction of various species ig Tigers.
  • I'm afraid this response in many cases could do more harm than good - because of the small issue of climate change. There is no doubt that climate change will force many animals and plants to reclocate to areas more suitable for them as rain-patterns and local climates change. In the past that was less of a problem but human changes on the landscape - large scale agriculture and urban development for example - has bisected the land. To address this efforts will be needed to join up the landscape - creating corridors for movement. If this isn't considered, preserving species in fixed places will not be effective as these places become more inhospitable.

     

    In addition, maintaining species in small pockets affects their genetic stability, again, in the long-term methods to allow isolated pockets of species to move and interbreed has to be considered.

     

    Finally, by focusing on local pockets we could overlook the overall ecology. Many of these pockets will not remain ecologically viable if the landscape around them is changed beyond recognition - as this will affect all sorts of things like local climate, nutrient movement and so on. This is one of the reasons why Natural England is looking at a more wide, landscape scale response towards nature conservation.
