Welcome to NADEF...

 

What is the North American Dendroecological Fieldweek?  

The North American Dendroecological Fieldweek (NADEF) provides an 
intensive learning experience in dendrochronology. Previous experience in 
field and laboratory-based tree-ring techniques is not required. 
Participants range from new initiates in the field to seasoned veterans with
over 20 years or longer of experience. Group leaders of the fieldweek are
among the top scientists in the various fields of global environmental 
change. Everybody that participates in the fieldweeks learns new things 
because the projects and locations are different every year.

Why study the past?  
Human history often does not adequately cover the range of past 
variability in many natural processes because of either the short length of 
available records or gaps in their spatial coverage, or both. Information 
about past variability is necessary to identify boundary conditions against 
which to assess future variability, especially to detect unprecedented 
changes that may be the result of human-induced climate or ecological 
change. Researchers in many natural science disciplines must therefore 
turn from instrumental or other written records to proxy data to broaden 
our understanding of temporal and spatial variability in natural phenomena 
under study

How is the NADEF organized?  
During the fieldweek, we spend the first day taking a tour of the local area 
and listen to engaging lectures from experts familiar with the local region. 
The group leaders (usually five) also briefly explain their proposed 
projects so that participants can be thinking about in which project they 
wish to participate. The 40 participants choose which group to join for the 
rest of the week. Each group spends 1-2 days conducting fieldwork, 
followed by three days of laboratory preparation and analyses. We also 
have a series of evening presentations and workshops during the week 
with topics ranging from different applications of dendrochronology to 
how to sharpen and care for an increment borer. On the last day of the 
fieldweek, the groups get back together to present their findings to the 
other participants.

What benefits are gained from the NADEF?  
Without question, learning through experience has no equal. Since 1990, 
the Fieldweek has successfully challenged participants to explore new 
approaches to multi-disciplinary research. While we emphasize tree-ring 
research methods, we feel that Fieldweek projects have effectively 
combined elements from many different disciplines to design novel 
solutions to ecological hypotheses. The Fieldweek attracts a diverse 
audience from disciplines from locations around the world, never stays in 
one place, and addresses research topics concerning all types of natural 
science. It is usually a very intense week, with a vast amount of work 
accomplished by dedicated participants who come to learn. Past 
Fieldweek projects have been published, used as bases for proposals to 
funding agencies, or formed core parts of theses or dissertations.
