[Box 1 An Example of Disturbance: Sixty-four acres of Baltimore’s central business district was destroyed by a fire in 1904. The origin of the fire is unknown. It was extinguished when winds changed and backed the fire against the Jones Falls stream. Fire fighting equipment brought in from other cities could not be used due to the incompatibility of the hose fittings with Baltimore hydrants. Referred to as the Great Fire, this event was one of the last unintentional fires in a major American city. Note that the 1906 post-earthquake fire in San Francisco owed much of its origin to intentional generation of firebreaks. (Olson 1997)]
Press and Pulse. These terms contrast events that have sharp attack and short duration -- Pulses -- with events that establish persistent new conditions. While the term "pulse" may be essentially the same as disturbance, press can have either the direct physical effects like disturbances or the more physiological effects of stresses. Note that the term pulse does not necessarily imply a regular rhythm of events.
The Urban Context
“engineering” resilience as capacity to return to a fixed equilibrium point.

BES at the All Scientists' MeetingEvery three years, the participants in the Long-Term Ecological Research (LTER) Network meet to share and compare results, and to plan for the future. this effort, involving more than one thousand researchers, educators, artists, and other collaborators in LTER, is called an All Scientists' Meeting. The details of this large meeting can be found on the website of the LTER Network: http://www.lternet.edu/node/49531
Members of BES will be presenting posters, plenary talks, and workshops. We'll report on some of the highlights after the meeting is done.
An Overview of BES for the ASM
Trees, Vegetation: Patchiness, Change, and Function
The Urban Stream Dis/Continuum: Patterns and Processes1 - 2. The results clustered in the right hand panel of the poster focus on streams. Kaushal and Belt (2012) have proposed a conceptual refinement to the stream continuum concept to apply this widely used comparative tool to urban systems. They emphasize the role of engineering, and the effects of enhanced connections in hydrological flow paths, along with the effects of disruptions in hydrological flows. Some of these connections and disconnections are intentional, while others are incidental to the way water is routed. They present data to show that stream contamination depends on where in this complex dis/continuum a sampling station is located.
3. Detention basins are designed to control the flow of stormwater and reduce the loading of copious rains into storm sewers while continuing to avoid street and structure flooding. Neil Bettez and Peter Groffman (submitted for publication) have shown that although several kinds of detention structures were engineered to control stormwater, in fact, they are also adaptive for reducing the amount of nitrate in stormwater. They thus can contribute to improving the water quality downstream. Some of these engineered structures facilitate enough biological processing of nitrate that they do better than natural riparian zones in the area.
Social and Educational Processes
The poster places these results and concepts into a graphical form. This will be on display throughout the All Scientists Meeting in Colorado during the week of 9 - 13 September 2012. We hope it gives a little flavor of where BES is going in its third phase, motivated by the pressure of cities to become more sustainable.

|Vollmer Center, site of BES' 2012 Annual Meeting|
Keynote by Prof Sherry Olson
First, we are privileged to have Sherry Olson as our keynote speaker this year. Prof. Olson is author of a classic book on Baltimore as well as other important works on urban geography and history. As detailed in an earlier post (http://besdirector.blogspot.com/2012/08/bes-book-of-year-baltimore-building-of.html), she will talk about "The Growth Machine: Its Environmental Legacy." This talk should put us in the mind for synthesis, which is one of the goals of our annual interactions as an inclusive community.
A Chance to Link Science and Art
This year's Annual Meeting will also feature a photography exhibit by Lynn Cazabon (http://besdirector.blogspot.com/2012/08/lynn-cazabon-bess-first-artist-in.html). She is BES's first official Artist-In-Residence. Building upon the success of our earlier connections with artists, BES is establishing a tradition to connect art and science. Attendees at this year's meeting will be treated to a display of photographs from Lynn's widely known and acknowledged work.
Gearing Up for the Mid-Term Review
Midway through each six-year funding cycle, the National Science Foundation conducts an external review of the Baltimore Ecosystem Study LTER. All LTER projects undergo this rigorous external evaluation to determine whether they are on track with the research, educational, and outreach commitments they made in their grant proposals. These reviews also help each project prepare for its next full grant proposal to NSF.
Our mid-term review for this grant cycle will take place in October next year. In order to make this most convenient for BES members, and to ensure a broad participation of our community, the mid-term review will overlap with part of the Annual Meeting in 2013. Because of this, it is important for all members of the BES community to understand the mid-term review process, and to learn how to prepare to best articulate their role and contributions to the mission of BES.
Part of our preparation will be to outline the book that BES will design to synthesize what by then will be 15 years of integrated urban socio-ecological research, educational research and programs, and interaction with communities and decision leaders in the Baltimore region. The Annual Meeting will be a chance to inform all members of BES about the plans for this book, and to be sure that all who wish to contribute have a pathway to do so.
Celebrate the Community
|Lady Baltimore Statue at Cylburn|
A Charm City Venue
Our meeting will take place at the Vollmer Center, nestled in the City's beautiful Cylburn Arboretum. This location has been a hit with BES Annual Meeting attendees in the past. During breaks, join your firends and colleagues for walks on the many trails through the woods and gardens overlooking the Jones Falls Valley. See you there!

A Deepening Commitment to Art
Exhibit at BES Annual Meeting

As opposed to ‘gray’ infrastructure, which includes transportation and utility networks, green infrastructure is interconnected ecological systems that include natural areas such as forests and streams as well as constructed elements such as urban parks, trails, streetscapes, stormwater management practices, community gardens, and urban agriculture.
Green infrastructure provides critical environmental functions and benefits including cleaner water, cleaner air, enhanced habitat and biodiversity. It also provides key social and economic functions such as decreased energy costs, opportunities for recreation and economic development, as well as improved health and quality of life.
