About Nick Haddad

Dr. Nick Haddad is Senior Terrestrial Ecologist in the Department of Integrative Biology at Michigan State University and Kellogg Biological Station. For more than 20 years, he has been studying how plants and animals use corridors. He has worked in the largest and longest-running corridor experiment, the Savannah River Site Corridor Project, and he has studied natural corridors used by rare butterflies. His latest book, The Last Butterflies, is currently available from Princeton University Press.

Determining corridor width

2019-01-14T11:57:37-05:00 January 6th, 2015|

One of the most vexing problems in corridor design is: how wide should corridors be? This may be the most frequent question I am asked by land managers who are planning to create or restore [...]

The dangers of narrow corridors

2016-10-14T10:11:10-04:00 April 19th, 2013|

Corridors are envisioned to benefit biodiversity -- re-connecting landscapes that have become fragmented, and providing safe passage for plants and animals across landscapes that are increasingly dominated by humans.  Yet, corridors could cause harm to [...]

Wildlife corridors on three continents

2017-11-20T16:00:58-05:00 April 3rd, 2013|

Corridors have proliferated in the past decade.  Not just plans for corridors, or lines drawn on a map as hypothetical connections, but real corridors intended for the conservation of biodiversity.  A recent special feature on [...]

Turkey’s first wildlife corridor

2016-10-14T10:11:17-04:00 September 5th, 2012|

Efforts are underway to create Turkey's first corridor. The new 82km long corridor will conserve over 23,000 ha. The corridor will protect Turkey's great diversity of plants and animals, including the Caucasian lynx, brown bear, [...]

Climate change shifts dispersal corridors

2016-10-14T10:11:17-04:00 September 5th, 2012|

Increasing temperatures due to climate change can be particularly detrimental to boreal species that rely on extensive snow depth and snow persistence into early spring for breeding. If seasonal winter conditions shorten each year and [...]

The Metatron: a large connectivity experiment

2016-10-14T10:11:17-04:00 August 29th, 2012|

The Metatron Experiment A new, large experimental network of corridors promises to test aspects of corridor function that are nearly impossible to control in observational studies. The Metatron consists of a series of enclosed [...]
