"Without relocating species we are destined to lose some of our most important and iconic wildlife, but at the end of the day we also need viable ecosystems into which we can move species"....so says Dr. Tara Martin of CSIRO ,,,,,,,,,, ASSISTED COLONISATION is the label that we have given to mans active participation in moving plants and animals that are endangered due to climate change, to new habitat where they will have a long range opportunity to persist.......This paradigm is being studied for its viability as changing temperatures increasingly are bringing adverse impacts to the landscape........My question is what if the climate continues to weave out of control in the the new regions where you "deposit" the animals and plants ,,,,,Then what do you do?...........Once again, we always seem bent(due to our greed and short term horizon) on treating the disease rather than trying to prevent the disease from happening in the first place.........LET US STOP BURNING FOSSIL FUELS AND SIMULTANEOUSLY NOT TAINT EVERY MOUNTAINTOP, FOREST, FARMLAND, DESERT AND PRAIRIE WITH GIANT WINDMILLS AND SOLAR PANELS.............PANELS AND WINDMILLS TO POWER US UP WHERE WE HAVE ALREADY ALTERED THE LANDSCAPE AND NOT WHERE THE LAND IS CURRENTLY SITTING OPEN AND FREE OF MANS IMPACT

Species Affected by Climate Change: To Shift or Not to Shift?

Relocating species threatened by climate change is a radical and hotly debated strategy for maintaining biodiversity. In a paper published August 10 in the journal Nature Climate Change, researchers from CSIRO, University of Queensland and United States Geological Survey present a pragmatic decision framework for determining when, if ever, to move species in the face of climate change.

"As our climate changes more rapidly than species can adapt or disperse, natural resource managers increasingly want to know what adaptation options are available to help them conserve biodiversity," said co-author, CSIRO researcher and research fellow at the University of Queensland Dr Eve McDonald-Madden.

Managed relocation, also known as assisted colonisation, of species involves moving plants or animals from an area that is, or will become, untenable because of climate change, to areas where there are more suitable climatic conditions but in which the plants or animals have not occurred previously."While the virtues of managed relocation of species are being debated by the scientific community, the reality is that it is already occurring.

"The decision-making framework we have developed shows that the best timing for moving species depends on many factors such as: the size of the population, the expected losses in the population through relocation, and the expected numbers that the new location could be expected to support.
"It would also rely on good predictions about the impact of climate shifts on a particular species and the suitability of areas to which they can move -- an often difficult issue in the case of rare species because we just don't have this sort of detailed information," Dr McDonald-Madden said.

CSIRO researcher Dr Tara Martin said monitoring and learning about how potentially climate change-affected plants and animals function in their 'native' ecosystems will play a crucial role in ensuring that managed relocation plans succeed."Active adaptive management is important when we are unsure of what the climatic changes are likely to be in the current habitat."Our framework provides managers with a rational basis for making timely decisions under uncertainty to ensure species persistence in the long-term" Dr Martin said.

"Without relocating species we are destined to lose some of our most important and iconic wildlife, but at the end of the day we also need viable ecosystems into which we can move species.
"Managed relocation is not a quick fix. It will be used in some specific circumstances for species that we really care about, but it will not be a saviour for all biodiversity in the face of climate change," Dr Martin said.
