- Slide 1
- Pei-Fen Lee Institute of Ecology and Evolutionary Biology National Taiwan University 1
- Slide 2
- Development and Purposes Biodiversity action plan in Taiwan Committee of Sustainable Development Environmental monitoring Specific wildlife groups Mammal (bat), bird, amphibian, and butterfly 2
- Slide 3
- Bird Monitoring What? Breeding or migratory species? Where? Spatial coverage When? Efficient and representative How? Standard protocol A comprehensive survey covering entire Taiwan using volunteers on 155 breeding bird species 3
- Slide 4
- Previous Work or Development Sustainable indicators initiated by EPA Only in design phase, no further survey Biodiversity inventory by Council of Agriculture Only in northern Taiwan 5 years Local sustainable indicators Taipei city (2007- ) 4
- Slide 5
- Biodiversity Inventory Only 5 year 1999 2003 200 projects Convenient sampling Data records: 0.8 million Most are vegetation (0.55 million) With location info. Not well designed 5
- Slide 6
- Previous Work or Development Forest bird survey Only last for 2 years New year bird count Only last for 2 years Not well organized Bird inventory by bird societies Comprehensive in spatial scale, but no clear geo-records and no standard sampling protocol 6
- Slide 7
- BBS in North America 7 1966 >7100 >3000 routes
- Slide 8
- BBS in UK 8 1994 >2000/yr >3000 sites
- Slide 9
- Single Species Monitoring Cattle Egret in North America Short term: Distribution Summer Long term: changes 1966 till now 9
- Slide 10
- Summer Visitors Population Trend in UK 10 50% reduction since 1994 Conservation strategy
- Slide 11
- Sustainable Development Indicators In UK 11 Ecological monitoring: 50% reduction in farm birds Biodiversity strategy
- Slide 12
- Indicators for Long-term Monitoring Same location Fixed survey time Long-term survey Proper design to adapt to budget, time and human resources constraints 12
- Slide 13
- Taiwan Breeding Bird Survey Long-term survey on breeding birds Large spatial scale Standard protocol Aims: ecological monitoring info, sustainable development indicators, distribution change under climate change impact, Data will open to the public 13
- Slide 14
- Bird societies Institute of Ecology and Evolutionary Biology, National Taiwan University Endemic Species Research Institute (since 2010) Participants 14
- Slide 15
- Selecting Sampling Sites Stratified random sampling scheme Representative of the environment Ecoregion Elevation (ecosystems) Volunteers Roads available, but avoiding over- developed areas 15
- Slide 16
- Point Count 16 Time (min.) Cumulative species (%) 6 min to reach 80% How much time spent in one point: 6 min.
- Slide 17
- When to conduct survey? 17 Bird detected (%) Hours after sunrise (hr) Noon 0-5 hrs after sunrise Breeding season
- Slide 18
- Sampling Sites (Routes) and Points Each sites: 6 10 points Point spacing > 200m Points should be < 4km in length 18
- Slide 19
- Identifying the species by sight or sound avoid double sampling Recording distance 100m Passing by Each Point: 6 min survey time ( ) 100m 25m 0m
- Slide 20
- Which Months? Twice per breeding season Consideration of the elevation difference > 2500 m, May & June 1000-2500 m, April & June < 1000 m, March & May
