Summary:
New study shows home sweet home can be too sweet for some wildlife,
and easing conservation standards can benefit both wildlife
and people.



FULL STORY ==========================================================================
In the ongoing quest to understand what makes a good wildlife habitat, surprising new research shows there may be too much of a good thing when
it comes to pinpointing optimal conditions. Embracing somewhat reduced standards can be good news to conservation managers.


========================================================================== Research by Michigan State University (MSU) scientists show that an
animal - - in this case a giant panda -- should be happy enough to thrive,
but not so content they don't want to move around and find new mates.

The research in this month's Conservation Biology has broader
implications- it is not necessary to have 100 percent of the area as
habitat to support pandas, and in fact pandas would benefit from some unsuitable habitat across the landscape.

"This work provides hope to balance needs for ecological sustainability
and human well-being," said Jianguo "Jack" Liu, Rachel Carson Chair in Sustainability and a paper co-author. "Our results show it is possible
for both pandas and humans to thrive across coupled human and natural
systems." The paper's lead author, Thomas Connor, who recently received
his PhD from MSU's Center for Systems Integration and Sustainability
and is a postdoctoral scholar at University of California-Berkeley,
shows there's a balance when it comes to how happy an animal can be.

Managing habitat across the world to ensure wildlife -- especially
wildlife like giant pandas that are considered threatened -- can both
thrive and move around enough to ensure good genetic diversity. Scientists across the world have worried about habitat loss and fragmentation
leaving animals isolated, eventually using up resources or not being
able to find new mates and avoid inbreeding.

Lots of things can break up suitable wildlife habitat -- humans build
roads or develop properties, wildfires can burn forests, or in the
case of pandas, natural cycles result in bamboo flowering and die-off
events. Climate change can disrupt habitat too, with previously suitable habitat conditions changing to unsuitable due to changing temperature
and precipitation patterns.

Having ways for wildlife to get from one patch of habitat to another
help can solve the problem. What Connor and his team notes, however,
is a hitch. There seems to be a level at which a slice of panda habitat
is so nice, the panda doesn't have a reason to seek another patch. They
found that maximum gene flow in their studies panda population was found
not when the entire landscape was habitat, but when about 80% of it was.

"As opposed to the potential interpretation of our results that maximizing
the amount of habitat in a landscape can be bad for connectivity, I
think that our research suggests a message of hope," Connor said. "We
can effectively manage panda populations by conserving and restoring
habitat to intermediate levels.

In other words, we don't have to create perfect habitat to keep protecting pandas." Connor said that the pandas' famous habitat pickiness -- their singular reliance on bamboo to eat, their shyness that drives them away
from human disturbances, their preferences for shallow slopes and cooler temperatures - - means that this study likely has even more relevance
for other species.

The research was funded by the National Science Foundation.
