Background:
Phenology studies the seasonal timing of different
developmental stages and the life cycles of plants and
animals. Understanding the processes that impact these
developmental stages and forecasting phenological
stages are important to growers, food processors, crop
insurance and seed companies, the commodities
markets, and those who enjoy the aesthetics of plants.
Similarly, climate change modeling and satellite-based
forecasting systems need basic phenology networks and
models to interpret their spectral data, especially the
“greenness” or photosynthetic response to the
environment.
Background:
In Nebraska and the High Plains region, a phenology
network and the resulting models are needed to: 1)
simulate alternative crop adaptation and rotations, 2)
better target genotypes with value added quality traits to
the landscape, 3) improve irrigation water management,
4) design new decision support systems for integrated
pest management and organic agroecosystems, forecast
insect and plant disease outbreaks, and 5) provide the
cyberinfrastructure that can lead to information fusion
for complex ecosystems and societies.

Phenology and Environmental Change:
Challenges and Opportunities
• Our audience includes biologists (ecologists, crop
specialists), geologists/geographers, those involved in
remote sensing, modelers, and computer scientists.
• Our program was developed to bring in five speakers who
are specialists in phenology, climate change, land cover,
computer sciences, and data mining.
• We want to have ample time for discussions and have
provided some discussion questions for your use.
Phenology and Environmental Change:
Challenges and Opportunities
• Develop a common understanding of phenology and how it
might be related to the environment and climate change.
• Consider what types of databases and information can be
used to understand phenology as an environmental
indicator and for decision making. Can agricultural (crop)
databases be used?
• How can we coordinate the databases with computer
technology to begin “mining” our data and to model
ecosystems?
Phenology and Environmental Change:
Challenges and Opportunities
• How should the Nebraska efforts augment, supplement,
and collaborate with the national efforts?
• What would be a signature program in this area?
• We intend to write a report of this meeting so we can have
a citable summary of our activities. The report will also be
web accessible through our website:

• Should we consider having a workshop again next year?
