goals for the training session
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
inquiry context
Inquiry Context
  • How long does green-up take for a given species?
  • How does green-up differ among different species within a forested study area?
  • How does green-up relate to precipitation? To soil moisture?
  • Does temperature influence the rate of green-up?
why do globe scientists research green up
Why do GLOBE scientists research green-up?
  • To calculate growing season length and monitor interannual changes in growing season duration
  • To determine how environmental conditions such as air and soil temperature, precipitation, 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 green up
Science Content: What is green-up?

Green-up is the beginning of phenological changes that signal the start of a growing season for most plants.

science content important definitions
Science Content: Important Definitions

Dormancy is a state of suspended growth and metabolism.

Swelling is seen when the bud is getting bigger.

Budburst is the emergence of new leaves (photosynthetically active foliage) on plants, which signals the beginning of a new growing season cycle.

instruments green up
Instruments: Green-Up
  • GPS Receiver
  • Local Tree Identification Guide
  • Compass
  • Meter stick or tape measure (for grass study site)
  • Ruler (in mm)
  • Camera
  • Flagging Tape & Marker
the measurements
The Measurements
  • Green-Up Study Site Definition
    • GPS Measurement
    • Tree and shrub species or grass genus
    • Study Site pictures
  • Green-Up Protocol
    • For tree or shrub: date, bud condition or leaf length on four buds of the same branch
    • For grass: date, blade length on first four shoots to emerge
collecting data field lab guides data sheets
Collecting Data: Field/Lab Guides & Data Sheets

Field/Lab Guides:

  • Tree and Shrub Green-Up and Green-Down Site Selection Field Guide or Grass Green-Up and Green-Down Site Selection Field Guide
  • GPS Protocol Field Guide
  • Tree and Shrub Green-Up Protocol Field Guideor Grass Green-Up Protocol Field Guide

Data Sheets:

  • Green-Up and Green-Down Site Definition Sheet
  • GPS Investigation Data Sheet
  • Tree and Shrub Green-Up Data Sheet or Grass Green-Up Data Sheet
collecting data green up and green down study site
Collecting Data: Green-Up and Green-Down Study Site
  • Site Selection
  • At least 2 weeks before budburst
  • Convenient location
  • Native trees/shrubs or grasses that are not watered or fertilized are preferred
  • Tree and Shrub or Grass Selection
  • Identify dominant tree and shrub species or grass genus
  • For Tree or Shrub:
  • Select one or more dominant, native, deciduous trees/shrubs
  • Select and flag a healthy, good-sized branch on the equator-facing side
  • For Grass:
  • Select a one-meter square area dominated by grass plants

Collecting Data: Protocol
  • First Time
  • Locate and mark green grass shoot or bud at end of selected branch
  • Locate and mark three other closest buds or shoots
  • Photograph your site
  • Every Visit
  • For Tree or Shrub:
  • Examine each bud and determine if it is:Dormant, Swelling, Budburst, Length or Lost
  • Continue measuring until leaf stops increasing in length
  • For Grass:
  • Examine each shoot and determine if it is:No Shoot, Length or Lost
  • Continue measuring until leaf stops increasing in length
