Announcements Urban Forestry project for one more week. Turn in your writing assignments today and submit the identifications of the other group's photos to Cici. Discussion on readings on Thursday – the two short Science articles about rice domestication. Review examples from students Urban Forestry project Be organized!!! Spend the extra minute to improve the photo and digital photos are cheap!! Take a lot and throw away a lot! Is the plastic working?? October 28, 2011 – 7 PM – Allen Theatre Conservation Biology At a global scale, we are using natural resources faster than they are being renewed by natural processes. The Conservation Endgame At a global scale, we are using natural resources faster than they are being renewed by natural processes. The Conservation Endgame There is a global imbalance between consumption and biodiversity. The rich and developed countries are driving this ‘natural resource debt’ through excessive and pointless consumption. The Conservation Endgame How do we explain the importance of the natural world to people who only know and understand a human urban environment? Now, more people live in cities than on farms. So, we have an imbalance between city and rural people. The Conservation Endgame Jared Diamond, a famous scientist who has written several internationally bestselling books, presented several examples of how societies choose to collapse or choose to prosper in his book entitled, “COLLAPSE”. He hoped to discover what makes societies succeed and fail, as they reach the limits of their traditional use of resources. East Asian Monsoon 东亚季风 Fossil evidence of climate change and rainfall patterns is highly correlated with the rise and fall of civilizations in China. Yancheva et al. demonstrated that sudden changes in climate led to the downfall of civilizations on both side of the Atlantic Ocean. Yancheva et al. Nature (2007) The Conservation Endgame Civilizations are most vulnerable to climate changes when they are near the natural limits. If most of the population can barely find enough water, a prolonged drought can be disastrous. Al Gore, recent Nobel Prize winner, has warned about the dangers of global climate change. The Conservation Endgame In Western Chess, the player that captures the other’s king wins. Many books of strategy have been written. We can learn deep strategy from these simple games. Chess has two distinct phases: - the opening开局 - the endgame终局 The Conservation Endgame If one player does not easily win, the game will reach the 'endgame'. The endgame: Each player has only a few pieces left. The pieces are balanced in power. The situation can last for a long time and can result in a ‘draw’, where no player can win. The endgame requires a radical shift in strategy: the loss of a single piece can be fatal each move has high impact and major consequences. The Conservation Endgame The conservation endgame is not a match between equal competitors. Human population and consumption are still exploding. Most people do not know anything about natural resources. We are obviously reaching the limits of our ability to generate wealth from traditional ways of natural resource use. We obviously need a radical change in strategy and we must actively manage these resources What’s so special about Southeast Asia? Myers et al. 2000 ALL of Southeast Asia comprises one huge biodiversity hotspot!!! What’s so special about Southeast Asia? Relatively few active scientists and high levels of endemism Sodhi et al. 2004 Are protected areas enough? The island of Sulawesi in Indonesia is a good case study for developing effective strategies in the absence of detailed biotic information. Very complex geological setting ►Globally important ecoregion ►Biogeographic crossroads ►Highly endemic vertebrate fauna ► Subject of Ecoregional Conservation Assessment by the Nature Conservancy ► compiled 32 Landsat images Digitized geological map Digital elevation map Complete collections database from the National Herbarium of the Netherlands in Leiden Four week ground truthing survey of 17 locations across the island Forest change analysis for five key sites Remote sensing analysis to determine forest condition Sulawesi - A poorly known biodiversity hotspot Defined by having both major concentrations of species richness and large numbers of endemic species. Given high priority for protection. Remote sensing research 32 separate satellite images! No automated classification algorithm would give reliable results across all images Eventually, the entire island was ‘handclassified’ using a base map of forest/non-forest, visual inspection of image, and examination of the supervised classification results. Top Twenty Conservation Sites Based upon total cumulative ranks • A full range of portfolio sites and protected areas are included in the top twenty. • Additionally, the ranking system can be used at smaller geographic scales to identify conservation ‘frontlines’. • Cannon et al. 2007 Human population growth near PAs In a careful study of population change in the buffer zone around PAs, found a widespread trend of greater growth in buffer zones in comparison to rural areas in general Wittemyer et al 2008 Human population growth near PAs Proportion of growth was substantial and increased growth was correlated with deforestation within 50km of PA. Wittemyer et al 2008 Moth to the flame Positive correlation between human population in PA buffer zones and Donor investment PA staff density Positive correlation between human population in PA buffer zone and deforestation Reduced Emissions from Deforestation and Forest Degradation+ (REDD+) REDD+: will it be a good or bad thing for tropical countries? The global carbon market could potentially funnel billions of dollars into countries like Indonesia. These dollars buy the right to pollute given the tropical country maintains its forests. Corruption is wide and deep in many countries and corporations. Great potential for cheating and missed targets. Conservation Reserve Program by the USDA has been a big succcess Conservation Reserve Program by the USDA has been a big succcess Conservation Reserve Program (CRP) Over-production and marginal production sites were leased by the government for fallow. Erosion has been considerably reduced on marginal lands. Wildlife populations have rebounded. Most of these lands are returning to pasture and can provide good grazing. In this area, there is a problem with increased woody plant growth, which some see as negative. Practical realities Academic publication vs. practical action Do we need more detailed models? More spatially explicit and site specific models Less grand generalizations Are we looking for our car keys with an electron microscope? Many of the pressing conservation issues are obvious: law enforcement, less consumption, breaking down the separation between ‘wild’ and ‘domestic’ The rule of law Fundamentally, we need a new era of environmental accountability. If current laws, both nationally and internationally, were strictly enforced, the situation would already be much better Some form of tracking system for natural resources, e.g. DNA fingerprints or isotopic composition of tissue Remote sensing can help fight both illegal forest conversion and the spread of forest fires The increasing spread of democratic governments may help fight indigenous cultures of corruption and nepotism. Conservation realities General conservation challenges Limited money, energy, awareness, and expertise. Simple ignorance of major patterns of biodiversity and ecology. International conservation programs often suffer from apparent Alzheimer’s. Local NGOs are often more effective. General conservation strengths Young, energetic, and concerned people can make a difference through organization and outreach. Even in the most corrupt governments, there are pockets of honesty. Find them. Forests are resilient and can suffer substantial damage without collapse. http://wwf.panda.org/about_our_earth/all_public ations/living_planet_report/living_planet_report_ graphics/lpi_interactive/
