The Baltimore Ecosystem Study
Understanding metropolitan Baltimore as a living, ecological system
By Karl Schrass

H

Some Baltimore Ecosystem
Study Findings

Every day, examples of how intertwined people are with their
environment are evident, even in
densely developed cities where not
much nature seems to be left. We
see it in places like Ellicott City,
Maryland, only 10 miles outside of
Baltimore, which was devastated
by two " 1,000-year floods " within
two years, the result of a quickly
overdeveloped watershed or stories like that of P-22, the mountain

In 1980, the National Science
Foundation (NSF) funded research
programs at 28 sites, the first LongTerm Ecological Research (LTER)
sites, to provide a longer view to
support ecological discovery on the
influence of long-term and largescale phenomenon. Each LTER
site involves dozens of researchers
and typically includes microbial,
community and landscape ecologists, as well as hydrologists, geochemists, social scientists, economists and even the occasional
artist, historian or philosopher. The
shared knowledge of place offers

ow do humans and nature interact in cities? How do social,
political and economic factors shape the urban environment?
And, how do urban areas challenge our thinking about what is
natural? These questions are becoming increasingly important,
as the number of people living in cities grows every year. Currently, the 50
largest cities in the United States account for more than 50 percent of the
total population, and the growth of cities is projected to continue for the
foreseeable future.

lion that has taken up residence below the famous Hollywood sign in
Griffith Park. There is a clear need
for a more nuanced understanding
of the reciprocal relationships that
influence urban environments; yet,
very few cities have long-term data
on how the complex interactions
between people and nature have
changed over time. But, Baltimore,
host city for the 2019 NRPA Annual Conference, is one of the best
