Editing Ellesmere Island (section)

===Protected areas===
More than one-fifth of the island is protected as [[Quttinirpaaq National Park]] (formerly Ellesmere Island National Park Reserve), which includes seven [[fjord]]s and a variety of [[glacier]]s, as well as [[Lake Hazen]], North America's largest lake north of the [[Arctic Circle]]. [[Barbeau Peak]], the highest mountain in Nunavut ({{cvt|2616|m|disp=sqbr}}) is located in the [[British Empire Range]] on Ellesmere Island. The most northern [[mountain range]] in the world, the [[Challenger Mountains]], is located in the northeast region of the island. The northern lobe of the island is called [[Grant Land]].

In July 2007, a study noted the disappearance of habitat for [[Anseriformes|waterfowl]], [[invertebrate]]s, and [[algae]] on Ellesmere Island. According to [[John Smol]] of [[Queen's University at Kingston|Queen's University]] in [[Kingston, Ontario]], and Marianne S. V. Douglas of the [[University of Alberta]] in [[Edmonton]], warming conditions and evaporation have caused low water levels and changes in the chemistry of ponds and wetlands in the area. The researchers noted that "In the 1980s they often needed to wear hip waders to make their way to the ponds...while by 2006 the same areas were dry enough to burn."<ref name="enn"/>
