New Understanding of Panda Habitat, Resiliency

Michigan State University (MSU) research shows that pandas are more resilient and flexible than previously believed.

Information gleaned from 30 years of scientific literature suggests that pandas are inflexible in regards to habitat. Those conclusions morphed into conventional wisdom and have guided policy in China. Vanessa Hull, a postdoctoral research associate at MSU’s Center for Systems Integration and Sustainability spent three years stalking giant pandas in China’s 21,300 square-kilometer Wolong Nature Reserve where an estimated 1,600 wild giant pandas have been relegated. During this time, she found a number of inconsistencies and lack of consensus on crucial matters in the existing literature detailing panda habitat selection.

“Panda habitat selection is a complex process that we are still trying to unravel,” said Jianguo “Jack” Liu, Rachel Carson Chair in Sustainability and MSU AgBioResearch scientist. “Pandas are part of coupled human and natural systems where humans have changed so much in their habitat.”

Hull and her colleagues drew up analysis of all the research projects and sought to separate studies that focus on where pandas live from studies that examine what kind of choices they make when multiple types of habitat are available. They discovered that they may not be as picky as thought.

The research shows, for instance, that pandas are willing to live in secondary forests – forests that have been logged and have regrown. They also don’t seem as selective about slope and are willing to climb depending on which of the many varieties of bamboo is growing, or what type of forest it was in.

They also found that there is a complex relationship between trees and bamboo. Pandas choose different forest types as places to spend their time, as long as bamboo is available.

“It’s exciting to see the flexibility pandas have, or at least see that they are choosing areas I didn’t think could support them,” Hull said. “It gives you hope. They’ve survived throughout many challenges over so many millions of years; it would be sad to think humans came along and threw it all away. This also suggests we should stay on board and try to make things better for them.”

The paper is published in Ursus, the journal of the International Association for Bear Research and Management.
