Recommendations from NEON Climate Workshop
•Establish a National Phenology Network that includes
public observers and leverages existing ecological networks
•Explore integration of NPN w/ Coop Network (NERON)
•develop a working group that includes phenology & remote
sensing experts
– a continental-scale network for regionally appropriate
native plant species & cloned indicator plants (e.g., lilac)
– thorough understanding of phenological cycles &
relationship to climate, hydrology, ecosystem processes
– comprehensive ground-truthing of green-up & other
remotely sensed phenology
– detect & discriminate long-term phenological trends
in response to long-term climate variability & global
warming

Study of the timing of recurring

forces, and the interrelation among
phases of same or different species

first leaf, flowering, fruiting,
turning of leaves, animal migration,
emergence, growth stages, breeding,
nesting, hibernation, etc.
I. Why phenology is
important
PREAMBLE: Phenology is a far-reaching component of
environmental science but is poorly understood. Critical
questions include how environmental factors affect the
phenology of different organisms, and how those
factors vary in importance on different spatial and
temporal scales. We need to know how phenology
affects the abundance and diversity of organisms, their
function and interactions in the environment, especially
their effects on fluxes in water, energy, and chemical
elements at various scales. With sufficient
observations and understanding, phenology can be used
as a predictor for other processes and variables of
importance at local to global scales, and could drive a
variety of ecological forecast models with both
scientific and practical applications.

• Joe Caprio Agricultural
Climatologist at Montana State
Univ., Bozeman beginning in 1955
• Started lilac network in 1956;
added honeysuckles in 1968
• Climatological observers, agric.

states in 1956 to 2500 observers
in 12 states by 1970
• WRPN terminated when Caprio
retired in 1994
• Eastern US Network started by
W.L. Coville 1961, lost funding
1986, but continued since by

V. Monitoring Structure
of USA-NPN
The predictive potential of phenological phenomena
requires a new data resource- a national network of
integrated phenological observations and the tools to
analyze them at multiple scales. This network is
essential to evaluate ongoing environmental changes.
It can now capitalize on integration with other
observation networks and remote sensing products,
emerging technologies and data management
capabilities, myriad educational opportunities, and a
new readiness of the public to participate in
investigations of nature on a national scale.
USA-NPN Implementation Team 4/16/06
USA-NPN Vision Statement
USA-NPN will provide phenological information that
can be used to understand the role of the
timing of life cycle events in the biosphere. It will
establish a nationwide network of phenological
observations with simple and effective means to
input, report, and utilize these observations,
including the resources to provide the right
information at the right time for a wide range of
decisions made routinely by individual citizens and by
the Nation as a whole.

Want to track global warming in your own
backyard?
Tuesday, May 30, 2006
A program funded in part by the National
Science Foundation is recruiting citizen
scientists to note when lilacs, honeysuckles and
other plants first leaf out and bloom.
The data will help scientists track the arrival of
spring, which since 1955 is coming about six
days earlier in the Northern Hemisphere, says
Mark Schwartz, a climatologist at the
University of Wisconsin-Milwaukee.
Coordinated by Schwartz and Julio Betancourt,
a senior scientist with the U.S. Geological
Survey, the program aims to build a network of
observers to track changes in how plants
respond to the weather. Several universities
and federal agencies also are participating, as
are elementary and high school students across
the country.
Lilacs know what day it is

Remote Sensing
Objectives
Of USA-NPN
•
provide ground truth to
make the most of the
public investment in
remote sensing data
•
relate remote sensing
estimates to meaningful
biophysical attributes
•
allow detailed
biophysical inputs into a
variety of models (move
from on/off parameters
to nuanced values)
• facilitate thorough
understanding of
phenological phenomena,
including causes and
effects
Two levels of satellite data sets:
(1) Intensive data collection to support research in
technique development
- correspond to USA-NPN intensive sites
- cooperative with CEOS WGCV
- will follow WGCV protocols
- subset of high frequency MODIS data and higher
resolution data
- moderate resolution (Landsat and SPOT)
- high resolution (IKONOS, QuickBird) for
site characterization and scaling studies
(2) Wall-to-wall data collection
-MODIS observations = “backbone” of NPN
-MODIS Direct Broadcast antenna (DBS) at EROS
permits control of processing for USGS-related
applications (e.g., compositing schedule, lag-time, etc.)

Talking points for CIRMOUNT-MTNCLIM 2006
• NPN seeks institutional partners & individual volunteers in West
•Revitalize Western States Phenological Network, this time focused on
lilac/honeysuckle + native + non-native species
• Criteria for selection and siting of NPN observations for westernmountains regions?
• list of target species & protocols from CIRMOUNT perspective.
• NPN is working with NOAA and NWS to integrate phenological
observations in data entry system WXCoder III. What about MONET?
• Finally, what can NPN do for CIRMOUNT in terms of monitoring,
research, & applications of phenology, or for organizational support?
• eg., Srategic location of phenological monitoring for calibrating treering chronologies, particularly near upper treeline.
