…it is the study of the timing
of recurring plant and animal
life-cycle stages, or
phenophases, and their
relationship to environmental
conditions.
The science of the
seasons
• Blooms and buds
• Hibernation,
migration, emergence
• Easy to observe

Phenology
USA National Phenology Network
Primary goal
• Create a standardized
dataset for use in multiple
types of research.
UNDERSTAND HOW SPECIES
AND LANDSCAPES ARE
RESPONDING TO CLIMATE
CHANGE.
• Make phenology data, models
and related information
available.
• Encourage people of all ages
and backgrounds to observe
and record phenology.

 Long term monitoring of
the same individual plants
 Importance of entering the
“no” observations
 At least weekly
observations - catch the
first “yes”
 If uncertain, use the “?”
Leaves
Flowers
Fruits
Why do we care about these phenophases?
Photo: Brian F Powell
• Canopy –carbon sequestration, food for wildlife
– Fast green-up – longer amount of time for carbon
to be taken up by a tree
– Calibrate remotely-sensed images
• Peak flower – wildflower viewing, pollination
• Fruiting – food for wildlife
We actually don’t need 100% certainty!

What is intensity?
If you answer “Yes” or “Uncertain” to a phenophase –
you may be asked an additional question about the
degree to which the phenophase is expressed,
for example:
• How many leaf buds are breaking?
• What percent of flowers are open?
• How much pollen do you see?
Estimating Intensity: Outline
1. Counts in number bins
(ie “How many --- are present?”)
2. Percent in bins
(ie “What percent of flowers are open?”)
3. Percent canopy
(ie “What percent of the canopy is full with leaves?”)
4. Oddballs: Leaf size percentage, how much pollen is
released
 The definitions were written to be taken literally.
The definitions are there to help
Do you see…
open flowers?
Open flowers : For Cornus florida, ignore the four large, white bracts and
watch for the opening of the small flowers in the center of the bracts.

end of the bud, but before the first leaf from the bud has unfolded
to expose the leaf stalk (petiole) or leaf base.

Fruit
Fruit
Fruit: One or more fruits are visible on the plant. For Acer rubrum,
the fruit is two joined seeds in a "V" shape, each seed having a wing,
that changes from green or red to tan or brownish and drops from the
plant.
Yes for fruit
No for ripe fruit

Ripe Fruit: One or more ripe fruits are visible on the plant. For Acer
rubrum, a fruit is considered ripe when it has turned tan or brownish
and readily drops from the plant when touched.

Recent fruit drop
One or more mature fruits or seeds have dropped or been removed
from the plant since your last visit. Do not include obviously
immature fruits that have dropped before ripening, such as in a heavy
rain or wind, or empty fruits that had long ago dropped all of their
seeds but remained on the plant.
 Yes, if a storm seems to have
brought a lot of ripe or almost
ripe fruit down
 ?, if you cannot determine if
the fruit is old or recent.

One or more live, unfolded leaves are visible on the plant. A leaf is
considered "unfolded" once its entire length has emerged from the
breaking bud so that the leaf stalk (petiole) or leaf base is visible at its
point of attachment to the stem. Do not include fully dried or dead
leaves.
Flowers or flower buds
Flowers or flower buds: One or more fresh open or unopened
flowers or flower buds are visible on the plant. Include flower buds
that are still developing, but do not include wilted or dried
flowers.

 Get to know the species
 Leaves and flowers may develop in the same bud (e.g. sugar
maple)
 Before reporting breaking leaf buds, wait for green leaf tip to
emerge

 If unsure, make a comment on the first date you see a bud
expanding

 If it turns out to be a flower bud, go back and report “yes” to flowers
or flower buds starting with the date with comment
