This course is for anybody who wants to be seriously engaged in field
botany and plant ecology It has three main threads: 1) gaining
some familiarity with research questions and approaches in plant
ecology, 2) doing some field-based group projects that will
increase familiarity with local ecological patterns, and 3) learning
more of the local flora. To be really comfortable with these
agendas you'll need to have some experience with reading the scientific
primary literature, be able to follow quantitative methods of data
analysis and adopt some of them, be comfortable in the field, and have
at least an introductory acquaintance with the ecology and flora of the
northeast. You can certainly make up considerable ground on any
of these with focused work, but be aware that you may need to do that
if any of these are problematic!
We will begin the term in a 'journal-club' format with reading and
intensive discussion of a series of current and recent research
papers. Each of you will take primary responsibility for
facilitating at least one such discussion. We'll also introduce
some of the tools used in plant ecology research. Once the
weather permits, we will be spending most Thursday afternoons in the
field (using the full 2-6 period and starting early when possible), visiting regional natural areas, doing vegetation sampling,
developing floral lists, and contributing to a data-base of information
about natural features.
During the first weeks of term, we will meet 2:10-4:00 on both Monday
and Thursday for paper discussions and such. Later in the term,
Monday meetings may be more geared toward work on individual and group
Evaluation will be very heavily based on participation in
and contribution to all aspects of the class, including design,
development, and implementation of projects. There will be
writing assignments; these will be developed as the work proceeds and,
in part, will depend on the nature of projects developed.

OF YOU WILL BE CHOOSING PAPERS FOR DISCUSSION OVER THE NEXT SEVERAL
WEEKS. I'd like to focus, initially, on getting a general sense
of understanding and current research on vegetation structuring and
dynamics for northeastern forests. Here are some papers from last
10 years or so that would be appropriate, but you might find others
(these are all mesic forest oriented; if you're interested in something
else -- dry forests, bogs, alpine... -- let's talk about possibilities). BUT START LOOKING AT POSSIBILITIES -- if possible, come to first class with an idea or two for possible readings...
