• legacy of deforestation –some of world’s highest

• highest modern mammal extinction rate on Earth

• continued mammal declines due to altered fire regimes

• meso-predator release• Murray-Darling Basin a mess• rates of changing climate in

Southern Hemisphere• 2nd-highest GHG emitters per

capita on Earth

intact biological communities and functioning species interactions provide humanity with a host of ‘services’ that support or improve our quality

Page 34: Current State of World Biodiversity: our impoverished future life support system

• ~ 90 % of all wild plant species require animal pollinators for fruit & seed set

• ~ 35 % of all human crops require pollination by insects (> 50 % by Apis mellifera)

• domestic honey bees declined in USA by 59 % since 1947 & in Europe by 25 % since 1985

• bees (& other pollinators) require more than just crops to complete life cycle

• decline mostly from habitat loss, fragmentation & degradation

1990-2000• ~100,000 people killed• 320 million people displaced• total reported damages > US$1151 billion

Carbon Farming Initiative (2011)• financial incentive to land managers & farmers to reduce GHG

emissions from BAU or sequester (store) C on land (offset scheme)

• Australian Carbon Credit Units (ACCU) = 1 t CO2-e = AU$23 (as of 01/07/12)

• ACCU rise 2.5 % yr-1 until 2014/2015; set by market thereafter

• emissions-avoidance: agricultural, introduced animal & legacy landfill emissions

• sequestration-offsets: sequestering C in plants as they grow, increasing soil organic matter, avoided vegetation loss, afforestation, reforestation, revegetation, rangeland restoration and native forest protection

• must be additional, no leakage, permanent (unholy trinity)

• largest potential GHG mitigation using ecology: enhancing woody biomass

•most landscape changes likely compatible with biodiversity maintenance/enhancement

•but potentially many negative biodiversity outcomes if not done based on sound ecological principles

•more research on synergies, economics of trade-offs

• future conservation planning needs to incorporate GHG abatement values

• future C pricing largest driver of optimal trade-offs

What now?1.forests – stop all

deforestation now2.carbon – tax3.ecosystem services –

valuing what we get for free

4.restoration – fix the damage

5.population – no, we’re not Europe, USA or China
