inquiry context
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

why do globe scientists research budburst
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

science content what is budburst
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.

collecting data budburst study site
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
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
