Taiwan Breeding Bird Survey: Ecological MonitoringPei-Fen LeeInstitute of Ecology and Evolutionary BiologyNational Taiwan University1Development and PurposesBiodiversity action plan in TaiwanCommittee of Sustainable Development
Environmental monitoringSpecific wildlife groupsMammal (bat), bird, amphibian, and butterfly22Bird MonitoringWhat?Breeding or migratory species?Where?Spatial coverageWhen?Efficient and representativeHow?Standard protocol
A comprehensive survey covering entire Taiwan using volunteers on 155 breeding bird species
3Previous Work or DevelopmentSustainable indicators initiated by EPAOnly in design phase, no further surveyBiodiversity inventory by Council of AgricultureOnly in northern Taiwan5 yearsLocal sustainable indicatorsTaipei city (2007- )4Biodiversity InventoryOnly 5 year19992003200 projectsConvenient samplingData records: 0.8 millionMost are vegetation (0.55 million)With location info.Not well designed5
Previous Work or DevelopmentForest bird surveyOnly last for 2 yearsNew year bird countOnly last for 2 yearsNot well organizedBird inventory by bird societiesComprehensive in spatial scale, but no clear geo-records and no standard sampling protocol

Proper design to adapt to budget, time and human resources constraints12Taiwan Breeding Bird SurveyLong-term survey on breeding birdsLarge spatial scaleStandard protocolAims: ecological monitoring info, sustainable development indicators, distribution change under climate change impact, Data will open to the public13Bird societies

15Point Count16
Time (min.)Cumulative species (%)6 min to reach 80%How much time spent in one point: 6 min.When to conduct survey?17
Bird detected (%)Hours after sunrise (hr)Noon0-5 hrs after sunriseBreeding seasonSampling Sites (Routes) and PointsEach sites: 6 10 points
Point spacing > 200m
Points should be < 4km in length18
Identifying the species by sight or sound avoid double samplingRecording distance100mPassing by
Each Point: 6 min survey time()100m25m0mWhich Months?Twice per breeding seasonConsideration of the elevation difference
