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
