Monarch Butterfly

Monarch Butterfly

Latin name: Danaus Plexippus,
Conservsation status: vulnerable (population is decreasing)

Millions of Monarch butterflies migrate up to 3,000 miles each winter, farther than any other butterfly—travelling 50 to 100 miles a day. The Monarch can smell its mate from 5 miles away.

The annual North American migration of the Monarch is listed as a "threatened phenomenon." Climate related threats include: drought, storms, changes in precipitation and dependence on temperature to trigger migration and reproduction. The Monarch feeds and lays eggs exclusively on milkweed plants, so it is also highly vulnerable to herbicides and habitat destruction.


Other animals at risk

Whooping Crane
Whooping Crane
Before 1800 there were an estimated 10–20,000 Whooping Cranes in North America. By 1941, because of hunting and habitat destruction, there were fewer than 20. There are now approximately 350–380 in the wild. The wild Whooping Crane population has only one winter habitat—a wildlife refuge on the Gulf Coast in Texas; and one spring breeding habitat—a prairie wetlands in Alberta. Severe storms, sea level rise, drought, industrial development and oil spills threaten these habitats. Another significant threat to young Whooping Cranes is colliding with power lines in their migration corridor.
Bramble Cay Melomys
Bramble Cay Melomys
The Bramble Cay Melomys was the first species to be declared extinct because of climate change. Sea level rise and storm surges washed away its habitat, food and the last of the population. In 2014 scientists went searching in the hopes of starting a breeding program but were unable to find a pair. Other sea birds and turtles that live on the Cay are also threatened by storm surges and sea level rise.
Hawksbill Sea Turtle
Hawksbill Sea Turtle
Climate change may affect Hawksbill Turtles in various ways because they live in different habitats at different stages of life: open ocean, beaches, lagoons and coral reefs. Rising sand temperature of nesting beaches produces more females and other abnormalities in baby turtles. Adults live primarily in coral reefs—threatened by rising ocean temperature and acidity. Since ancient times the Hawksbill has been exploited for its shell. They are also threatened from fisheries by-catch, development, and a high sensitivity to oil spills. The population has decreased by an estimated 80% in the last 100 years.
Staghorn Coral
Staghorn Coral
In the last 30 years the Staghorn Coral population has decreased by 80% from disease, pollution, development and damage. Climate change is increasing the risk of extinction. Corals live in symbiotic (mutually beneficial) relation with algae. The coral receives nutrients and oxygen from algae, and the algae receive nutrients and carbon dioxide from the coral. Rising sea temperature increases algae growth so oxygen levels become too high for the coral, causing "bleaching"—the coral expels the algae and dies. Higher ocean acidity contributes to bleaching and also reduces the ability of corals and other marine animals to build hard shells. Other threats from climate change are sea level rise, changes in currents and storm damage.
