  1. 1. Bird responses to management intensity in a shade-coffee system, Southwestern Ethiopia Patrícia Rodrigues, Girma Shumi, Ine Dorresteijn, Jan Hanspach, Kristoffer Hylander*, Feyera Senbeta**, Joern Fischer El Jadida , Morocco September 2016 Identifying socio-ecological system properties that benefit both biodiversity conservation and food security * Stockholm University ** Addis Ababa University
  2. 2. CONTEXT Population growth Biodiversity hotspots Land use changes TROPICAL FORESTS
  3. 3. SOUTHWESTERN ETHIOPIA AFROMONTANE RAINFOREST HOTSPOT Elevation: 1800-2800m Highly biodiverse Birthplace of Coffee arabica Highlands of Southwestern Ethiopia
  4. 4. SOUTHWESTERN ETHIOPIA COFFEE PRODUCTION 41% of the country´s foreign currency income
  6. 6. SOUTHWESTERN ETHIOPIA LOW MANAGEMENT COFFEE FOREST Undisturbed understory until harvest season
  8. 8. How do birds respond to coffee management intensity? (Buechley et al. 2015; Gove et al. 2013, 2008) Unmanaged Natural ForestsSemi-managed Coffee ForestIntensively managed Coffee F. QUESTION WHY BIRDS? Providers of ecosystem services (seed dispersal, pest control…) (1) Community composition (2) Total species richness and total abundance (3) Abundance of functional groups RESPONSES OF:
  9. 9. Addis Ababa Jimma STUDY REGION AND SAMPLING SCHEME 52% Farmland 48% Woody Veg. Kebele 67 points, sampled twice, Nov 2015 to Feb 2016 Number of individuals; species Distance from observer (bands) RECORD bird songs and calls Info on vegetation on plot 20x20m - plant species richness - abundance of non-coffee species - dbh of big trees SAMPLING POINTS 10´ 06h00 – 10h00 Cost Distance Close Middle Far Interior STRATIFICATION

  14. 14. IMPLICATIONS FOR MANAGEMENT DECISIONS FINAL CONSIDERATIONS Negative response : total species richness and abundance of insectivores Unmanaged Natural ForestsSemi-managed Coffee ForestHighly managed Coffee F. No response for remaining classes: Low management plots as buffers for natural forests? SIMPLIFICATION OF HABITAT STRUCTURE
