What is causing habitat loss?

• Habitat loss is the main cause of biodiversity loss• Agriculture• Forestry• Urban development• Water projects

Deforestation

What are possible ways to address and improve habitat loss?

• Set priorities• Find biodiversity hotspots

A map of the 25 hotspots, which comprise 3-30% of the red areas.

The 8 hottest hotspots in terms of 5 factors:1. # of plants2. # of vertebrates3. Plant/area ratio4. Vertebrate/area

ratio5. % of remaining

primary vegetation compared to original

Improving Habitat Loss continued…

• The major threat to terrestrial systems and ocean fisheries are not the same

• Marine protected areas (or MPAs) can be utilized to address habitat loss in marine systems

• Three approaches:1. 1. Terrestrial park legislation can be

extended to cover marine areas2. 2. Fisheries legislation can be extended to

include protection of their habitat3. 3. Create a new governing agency to

oversee designated areas
