Assisted migration (Ecology 🏞️)

Assisted migration is "the intentional establishment of populations or meta-populations beyond the boundary of a species' historic range for the purpose of tracking suitable habitats through a period of changing climate...." It is therefore a nature conservation tactic by which plants or animals are intentionally moved to geographic location...

Non-native plants and animals expanding ranges 100-times faster than native species

"An international team of scientists has recently found that non-native species are expanding their ranges many orders of magnitude faster than native ones, in large part due to inadvertent human help. Even seemingly sedentary non-native plants are moving at three times the speed of their native counterparts in a race where, because of the rapid pace of climate change and its effect on habitat, speed matters."

"To survive, plants and animals need to be shifting their ranges by 3.25 kilometers per year just to keep up with the increasing temperatures and associated climactic shifts—a speed that native species cannot manage without human help."

"We know that the numbers of invasive plant species are increasing exponentially worldwide...Plant nurseries are exacerbating the climate-driven spread of invasives and that confronting invasives is one of the best ways to prepare for climate change. What we wanted to find out is how fast both native and non-native species are moving right now, and how far could they go."

"Essentially...there's no chance for native species to keep up with climate change without human help...We need to seriously consider and begin implementing assisted migration"

And stop selling 'ornamental horticultural' invasive species.
And of course stop polluting our atmosphere by burning fossil fuels.

"2 decades back, these southern #seedlings likely would have struggled to flourish here. Today, Palik can see the success of almost all the southern #trees they planted... the #climate is right for them... The climate typical of southern #Minnesota from 20 years ago is now in northern Minnesota. Palik’s project is an experiment in #AssistedMigration, the relocation of trees to help #woodlands adapt to #ClimateChange."
