Budburst Protocol Draft 2005
Goals for the Training Session • Provide an inquiry context for the data collection and science content • Provide accurate science content • Review procedures for data collection • Review data entry and analysis • Discuss classroom implementation ideas • Collect feedback from participants Draft 2005
Inquiry Context • When does budburst occur for the dominant tree species? • How does budburst differ between different tree and shrub species within a forested study area? • How does budburst vary year to year for the same species? • Which environmental factors most affect the timing of budburst on a particular species? Draft 2005
Local Inquiry Example Draft 2005
Why do GLOBE scientists research budburst? • To calculate growing season length and monitor interannual changes in growing season duration • To determine how environmental conditions such as air and soil temperature, soil moisture, and day length affect plant growth • To monitor the nature and extent of climate change and its effects on plants and animals • To help interpret satellite observations of greenness Draft 2005
Science Content: What is Budburst? Dormancy is a state of suspended growth and metabolism. Budburst is the emergence of new leaves (photosynthetically active foliage) on plants, which signals the beginning of a new growing season cycle. Dormant Bud Budburst Draft 2005
Instruments: Budburst • GPS Receiver • Local Tree Identification Guide • Flagging Tape & Marker • Binoculars (optional) Draft 2005
The Measurements • Budburst Study Site Definition • GPS Measurement • Tree/Shrub Species • Budburst Protocol • Date buds burst on 3 or more places of the same plant Draft 2005
Collecting Data: Field/Lab Guides & Data Sheets Field/Lab Guides: • Budburst Site Definition Field Guide • GPS Protocol or Offset GPS Protocol Field Guide • Budburst Protocol Field Guide Data Sheets: • Budburst Site Definition Sheet • GPS Investigation Data Sheet • Budburst Protocol Data Sheet Draft 2005
Collecting Data: Budburst Study Site • Site Selection • At least 2 weeks before budburst • Convenient location • Native trees that are minimally watered or fertilized are preferred • Tree Selection • Identify dominant tree species • Choose measurement strategy • Dominant overstory species • More than one overstory species • Overstory and/or understory species • Flag at least two trees from each species Draft 2005
Collecting Data: Budburst Protocol • Observe selected trees at least two weeks prior to budburst • Visit twice a week, initially until budburst appears anywhere on tree • Visit daily until budburst is seen on three separate locations of each tree Draft 2005
