Preserving Remnants Of The Past For Our Future


An effort is underway in Richardson to try to preserve tall grass blackland prairie and spring habitat within the city.  A growing group of advocates have stepped up to challenge the development's rezoning plan heading to the City Council. This is always a particularly challenging effort whenever such development proposals reach the level of the City Plan Commission on its way up.  As for the commission, their mission is clear as set in the local regulations and by the state.  As much as the land conservation advocates must work feverishly to challenge to protect this area, the final appeal can really only come down to the determination of a land owner.  How does this company, or individual, resolve the dilemma of an economic gain with an environmental and cultural loss to the community?  Does it matter to them? The questions regarding the outcome of the land always comes down to the land ethic of the land owner(s).  The community's efforts too often come out on the short end of these late appeals.  

But I had to ask myself, why is this now becoming an issue for this community?  Why is it only when the prairie land, or the rare or significant stand of trees, are under threat of destruction, do we come out vocally and aggressively and challenge these development initiatives?  I'm sure someone knew this land was here in the middle of a sprawling, expansive and infilling city. They knew it was always at risk. The conversations about these lands end up around restaurant tables and informally in conservation group meeting halls. Why were none of these comments in front of local representatives?  I understand it when it is land already under city protection.  You shouldn't have to fight to protect what is already protected to save it from our own grand visions of every square feet of city being developed. We live in a city where the small pockets of old growth forest and blackland prairie habitat remain there year after year until someone comes along and decides to buy it from a person very willing to sell for a profit.  Ultimately, it becomes more valuable to have it built. Where is the advocacy when these places are not challenged for its existence?  

Why are you not out there finding these places?  Why are you not talking to the landowners to give them options which they may have never considered?  Let's talk about conservation easements and development right transfers.  Let's talk about fundraising to protect something of value for the community. Are you afraid that knowledge of these locations will only spur someone to develop it?  This living in fear of development must end.  We must face the development specter head on and scout the trails before the development ever senses an opportunity.  Why are you not talking to your park boards to urge them to acquire these properties?  It may take years to convince a city to invest in it, or to raise the private funds to purchase it, but if this land is so critical, isn't it worth the long hard effort to do this before someone decides to build 14 houses on it or build a retail shopping center with massive parking lots?

We blame our city governments for being reactive.  But I find we citizens do this by our very nature as well.  We are far too timid when faced with a ravenous economy devouring land at a massive scale.  These places are out there now waiting discovery.  

Let's consider another idea.  We need to find solutions as part of the economic development program for the city to protect these places so we will be able to say we did our best to protect what had to be protected for the generations to come. Why isn't the preservation of our most critical areas an equal part with economic growth in the sustainability equation for the city?  Preservation is one part, development is another. Between them, we hold to and comprehend standards of conservation for the entire community that benefit everyone. And, who knows, maybe the development interests in your community will also help you find these places to protect so they will not have to face these challenges from you in the future.  It begins with communication and coming together to reach the same objectives.  We won't get all we want, but it's a start.

These most important and special places do not protect themselves, and city ordinances will not protect them for you.  It's you or the developer who steps up first, and it's best to have this determined long before it becomes a contest placed before a City Council.

Heritage Trees

A survivor.

In a sense, any old tree could be casually considered to be a "heritage" tree.  They are born in the distant past from our relative point in time and can represent to some a living marker of the history of our community, or it may be a unique representative of a ecological system that may no longer locally exist.  Some trees have a specific emotional relevance to a single person who may regard it as priceless. But there can be difficulties when we are trying to measure 'old' for a tree.  For certain trees, old may mean just a few decades of life.  But for others, the age of a tree can be expressed in centuries, and this is even true in North Texas.  So when we try to identify a tree as a Heritage Tree, we need to be careful to be able to define it for more than just its current age, but also for its particular value to its place in our history as a city, its particular physical condition and location, its species and size, for its history as it relates its particular biotic community, and, perhaps most importantly, for what it means for us to lose it.

I am not discussing the status of a "historic" tree which I would consider to be a specific heritage tree designated with a significant cultural importance to the community.  That's a topic for another time.

A Heritage Tree is only as valuable to our community as how we choose to define it.  For better or worse, we determine the extent of the value of any thing, and, all too often, any person.  All too often we are determined to base it solely on economics. But our humanity, for us to live up to the best of ourselves as people, must look beyond the simple minded monetary bias by which we are programmed. How you expand your mind on this is determined by your land ethic.  Is the tree a part of your community or not? Do we grant it a right to exist or not?  You must consider the rarity of the tree in its current location, and its inherent value to you, your property, and the community around you.  It's true that a tree has a different value to different people, and this simple scale of perception, and the following directed actions taken by a whim, will often be the sole decider of a tree's fate.  Humans have the rare position on this planet to make conscious decisions to determine the fate of other living organisms (our self-imposed right) which may be based on no other idea than to make the land visible for land speculators.  Our ability to decide is a gift, and a responsibility, we as a species fail to use properly. Ours is not always an instinctive decision, but when not done as an act of survival, our action can often be a foolish and short-sighted one.  Any way we look at it, we change the course of nature by our combined efforts and, in so doing, change entire ecosystems, and, as it continues to be shown, even a global climate system.

Searching for the heritage trees in our community often requires research to discover where forest remnants may have remained throughout city expansion.  
Over the past two centuries and before, man has been altering the ecological conditions of the Dallas area and North Texas, from the use of fire to manage an abundant game, to the introduction of the plow for agriculture, and for the construction of cities.  Trees and lush wild grassland prairies that had been surviving for centuries endured (and thrived with) these fires. Then land clearing for cattle and agriculture spread until their time was cut short when the human community found other uses for that land.  Wildlife was forced to the creeks and rivers and remaining pockets of open range while their populations diminished.  Trees were selectively removed as each new farm began production or each new town and roadway expanded across the open prairie.  Today, a very few of these large old giants and unspoiled soil plots remain to mark the passing of decades of human invasion on the land.  We are simply failing to recognize these rare specimens that remain in the path of further development.  These trees are the legacy left for us of the natural world that once was and can no longer be in the great expanse.  The passing of these trees and grasslands will leave us in a position where we will never see their like again even with our best intent and purpose of planting and re-planting and manufactured irrigation.  We are clumsy oafs who try to duplicate a world that we can never re-create. We decide where the trees will grow but fail to provide what is necessary for them.  Our landscapes are poor monuments for ourselves and with no regard to the life of the tree. As with all other things, we create our natural environment in our own image and to our purpose and advantage.  Fortunately, across Texas, there are many who have recognized these losses of community and ceded land for the preservation of these systems and there are people who have taken on the charge of being their stewards.  But, for the city, there is very little remaining.  It is for these last remaining pockets of ancient biological and cultural history that many others are taking the charge of attempting to protect a few places and trees within the inner city.  

If the loss of the old sentinels is acceptable to you at face value, then there really is nothing more to say.  It is the price of being a city dweller. The Dallas ordinance has a very significant purpose stated for the preservation of large trees.  This was determined two decades ago, but how quickly we can forget how and why these goals were established. A generation recognized we were losing critical members of our natural community to unrelenting expansion. But even in our best conservation efforts, we are losing our most significant trees to our expansion on these lands where these last remnants of the past age survive within the city.  Our designs for 'progress' do not take into account the locations of the rare old trees, but all things in the path of economic growth are susceptible to loss.  We, without proper and guided vision, set our pathways, our parking lots, and our desire to continually grow into the direction of these quiet giants. Our line of site sees only points A and B. The path between is a circumstance of cost and ownership.

We owe it to future generations to preserve a part of this legacy within the city in places other than cemeteries or old school campuses. These stands do not regenerate but can only be overtaken by mismanagement or clearing. Time will take these trees eventually, but perhaps Nature should decide this on its terms, not ours.  We need to remember these locations and protect them by selecting them ahead of new development.  We have no choice or they will be selected for us.  A tree that has endured here for multiple centuries has much more value than a Reforestation check or a newly planted parking lot tree, or square feet of a new tower.  It is far greater value to this planet than a car wash.  It should be respected and honored for the long life it has endured and the enormous benefits it continues to provide us.  It deserves far better than being considered a mere obstacle to development.  There are other trees that may rate lesser to us and will allow to be dismissed because we must.  But our few heritage trees are our defining natural emblems that should be able to live for the fullness of their lives.  In the city, this has been earned for those that have survived to this day. We owe it to ourselves as well to take the high road and find a path around the rare gem.

What are the heritage trees?  These are not defined, and perhaps may not become defined.  But in my mind they are trees like the post oak, the bur oak, the eastern redcedar, red oak, large elms, pecan (our State tree), the bois d'arc, and several others.  At what size should we consider them?  This can vary, but I once estimated the age of a 10-inch diameter post oak tree by its tree rings to the early European settlements of Dallas County.  These trees can grow much larger (and quite slowly) and extend in life for centuries.  

Who decides the value of our heritage trees?  It's not me.  Not alone.

Setting Objectives

Sometimes you CAN bend for something of greater value than your convenience.
The Dallas landscape and tree ordinance seems to be on many minds these days. But I am cautious to not allow myself to be removed from an objective position where I cannot view the entire universe of topics. Some are guided by a single initiative while I must view the Dallas forest infrastructure holistically - inside and outside of ordinance. The list of forestry issues we need to consider beyond a tree ordinance is extensive which makes me very grateful Dallas also has a city forester.  As I've indicated before, a city ordinance only gives you certain rules for certain standards and for certain conditions.  It sets parameters for development, one lot at a time, and then you live up to them or you don't.  The forest community is MUCH more complex than buildings and streets.  Ordinances need to keep the perspective of the urban landscape for future generations, and not just be simplified for the instant gratification of a beautiful landscaped oasis during the ribbon cutting.

Landscaping and tree protection problems are often left as trivial in the scope of all other things related to development.  Landscaping for many projects is the first thing to get squashed in a budget, and land and tree conservation is the last thing contemplated in design of the development.  There are individuals who do see the whole picture (and if we're fortunate, it's the owner), but sometimes the development team may not fully understand the objective of any landscape application, or where it may fall short.  Buildings and infrastructure age but are designed to not physically change in scale or function over the decades.  Trees stymie engineers because they don't follow straight lines and they don't obey boundaries, in the air or underground.  This is why large trees in landscape beds next to buildings is a bad idea.  Trees are alive and need to thrive.

Landscape ordinances are designed primarily with the focus on new construction.  The best of them may address some day to day management of the existing urban forest in general.  But the ordinances are mere tools to establish a direction for development to be completed like a puzzle of a larger system that is in place to meet the purpose, or objectives, laid out for the city.  These ordinance objectives are defined by the citizens, or more directly by their representatives.  The Article X (10) ordinance has a purpose section where all but one of the listed objectives were created with the original landscape ordinance of 1986.  Only one was initiated with the 1994 creation of the Tree Preservation, Removal, and Replacement regulations.  The purposes are listed below.  We can look to these objectives and ask if they meet all of our objectives today.

These objectives (or purpose) do not help us deal with the specifics for pro-active forest management.  They do not set into motion an aggressive effort to locate specific forested areas and trees we desire to preserve from development and place them into preservation, or conservation, areas.  The objectives do not help us regulate extremely poor tree maintenance and cutting practices which should be more regulated for the protection of the workers and the homeowners.  Since there are standards nationally recognized by the professional tree services in how to conduct proper tree care, why would you not require these standards on your property, or on city property? These existing objectives do not help us provide better information on planting trees correctly or provide adequate planting space and soil volume in city streets.  The objectives do not give us a tree inventory or direct us to forge a city-wide forest management plan.  How do we manage trees in alleyways, and around public utilities, or navigate through conflicts with our neighbors over a shared tree?  A tree dies on a vacated lot next to your home.  How is this addressed?  The sidewalk is buckling with the massive mature tree lifting slabs and pushing curbs.  Must you remove the tree?  There are answers to these problems but each situation is different and answers should be consistent.  But they are not found in this ordinance.

The urban forest community has many stories and there needs to be direction for the citizens of how to address them.  An ordinance will not provide all of these answers, but it can help establish parameters, benchmarks, and performance levels that everyone should follow, including - and especially - the City of Dallas.  Should we also pursue a Urban Forest Management Plan for the city?  This is an idea that has moved forward in many cities, including Austin, and will likely be discussed here for some time to come.

The door is open for discussion.  It is a moment to be positive and to seek creative answers to help the city move forward and prosper.

The process of development with its alteration of the natural topography, vegetation, and creation of impervious cover can have a negative effect on the ecological balance of an area by causing increases in air temperatures and accelerating the processes of runoff, erosion, and sedimentation.  The economic base of the city can and should be protected through the preservation and enhancement of the unique natural beauty, environment, and vegetative space in this area.  Recognizing that the general objectives of this article are to promote and protect the health, safety, and welfare of the public, the city council further declares that this article is adopted for the following specific purposes:

          (1)     To aid in stabilizing the environment's ecological balance by contributing to the processes of air purification, oxygen regeneration, ground-water recharge, and storm water runoff retardation, while at the same time aiding in noise, glare, wind, and heat abatement.

          (2)     To provide visual buffering between land uses of differing character to alleviate the harshness of urban life.

          (3)     To enhance the beautification of the city.

          (4)     To safeguard and enhance property values and to protect public and private investment.

          (5)     To conserve energy.

          (6)     To provide habitat for wildlife.

          (7)     To encourage the preservation of large trees which, once removed, can be replaced only after generations.

The Spring Of Our Discontent


Dallas urban forest canopy
You may have heard a rumor that the Dallas landscape and tree ordinance is about to come under review.  Of course, this rumor has been going for a good five years, but I think I can safely say the task is now finally in pre-production and getting ready to gear up for community discussion.  For many, it could not happen soon enough and has been needed for years. But I think, perhaps, the time in which we have waited will have been to a good service.  I believe time allows for opportunities for people to learn of new ideas, allows for people to put ideas together, and allows for unexpected alliances.

Before we open up into a conversation on this blog about the Article X (ten) ordinances, I think it may be wise to look beyond the scope of city regulation to help us identify our strengths and weaknesses, and to look into the book of players.  More importantly, I think we owe it to ourselves to define our objectives.  But to do this, we must understand our assets and our liabilities. What goals will we set and what exactly are we talking about when we talk about our trees, or our forests, or our land?  What is Dallas beyond the human equation and what really does matter?  What has value?  Should we define what value is?  You may not really be surprised how this word 'value' can be interpreted by different people.

People have been frustrated (I'm trying to be diplomatic) by the current tree ordinance for some time now and different people have different reasons.  I find each and every argument has a basis of merit, whether the complainant is a developer or private citizen, politician or small business owner, environmentalist or capitalist. We have to listen to each other in the coming months and find ways to connect.  Several people from different areas of interest have discussed this ordinance backwards and forwards for years now to seek understanding and consensus.  We have learned there are some places where there can be connections of understanding, but there will always be division elsewhere. We are individuals with different mindsets, and different cultural and moral perceptions. The challenge for a democracy is to find the balance and compromise that serves the entire community. But beyond looking at the negatives of an existing ordinance, we need to look at some of the positives that have helped us move forward in growth of our community for the past 20 years of this ordinance.  

For now, however, I want to begin to look at our forest infrastructure.  In the coming year, new research will be taken by others that will help us understand our urban forest (our community) in ways we haven't seen before.  We have a sprawling urban forest that originated in time with the expansion of human settlement across the Dallas territories as individual land owners - homeowners (namely, you) - planted the trees that help define and characterize your neighborhoods.  For us, the urban forest begins with your home and the trees on your land.  We will look at the other public lands, including the Great Trinity Forest which has been transformed over the past century as our agricultural uses settled down.  It is now a compromised sanctuary for wildlife, becoming revisited by our economic expansion.  How do we manage this? We need to understand more about the science beyond the beauty that surrounds us in our trees and the interrelationships between ourselves, the trees, the wildlife, and the air and water which nourishes us.  We need to comprehend the realities of how our urban forest is a vital living infrastructure which helps us to tolerate our existence (and others) in this city environment.  Trees help relieve crime and provide significant value to homes and neighborhoods.  How do we manage this forest for the long term while addressing our immediate needs?

As we start down the road with this new course for Dallas Trees, I want to help us identify our forest and to introduce ideas and science that can give us guidance.  We will discuss forest management for you as a land owner and for the community as a whole.  How do we become proactive in establishing a healthy forest instead of being reactive to its dangers? There are many things we can do in our communities today to improve our forest that do not require a tree ordinance.  Our success with our urban forest does not begin or end with regulation.  It is merely a tool to help us achieve objectives we must define.  We cannot define it without understanding it.  In the coming months, I want to help us learn more about our forest community, and in doing so, learn more about our places within it.  In understanding, we can grow a land ethic which can lead us to correct actions and not ruinous ones.  We will look at how to maintain a single tree through best management practices established by industry leaders, and help us in knowing how to project our tree forest cover for generations to come.

Our discontent is a symptom, in part, of something we do not yet fully understand.  Let's understand our forest, and our goals for that forest, before we regulate how to get to that end.

The November Trees

Lake Cliff planted with Reforestation Fund trees.

Based on my current confused and delirious state, I can tell we're now getting into the annual Fall tree planting season.  I've been lining up tree orders on procurement requests for three major park projects coming up in November, as well as putting together the pieces for our first neighborhood plantings.  As much as I enjoy the season of people gathering around to put trees in the ground, the paperwork is a rather mind-numbing venture. But, you know it's well worth it. During the last tree planting season of 2012-2013, we had our greatest planting numbers of nearly 1400 trees, since we began to reach out with the program.  By the end of the day today, we're at nearly 500 trees ordered just for our November rush.  We'll be on for planting trees through March.  Actually, I really need to put out a huge huzzah! for our city forester, Karen Woodard, who has taken on the real challenge of coordinating the park projects.  She's the heart and soul of these efforts.  When you see her during these events, give her a big thanks for her great efforts. 

Our season of planting is a result of tree mitigation payments into the Dallas Reforestation Fund. The fund was originally established back in 1994 when the City of Dallas created its new tree preservation ordinance.  Over the years it has seen continuing and growing interest from neighborhoods and organizations across the city for planting trees in parkways and other public property.  It has also served well to fund major park projects, much like the one happening on Saturday, November 2, at Friendship Park in North Dallas.

Our current schedule update is as follows:

November 2 - JFK Groves - 100 trees at Friendship Park (with Texas Trees Foundation).
November 9 - Trees Please - 150 trees at White Rock Lake near East Lawther.
November 9 - Stevens Park Neighborhood - our first neighborhood delivery for the season.
November 16 - DALLAS ARBOR DAY at Kiest Park with 150 trees.
November 16 - Wynnewood Heights Neighborhood - down the street from Kiest Park.
November 16 - Wynnewood Hills Neighborhood (tentative date).
November 22 - Elmwood Neighborhood (coordinated by the Texas Trees Foundation).
November 23 - M Streets neighborhoods

We may have another planting event or two thrown in there, but that is yet to be determined.  Then we take a break until December when we're expecting our first project associated with the Mowmentum Program at 10th and Oak Cliff Boulevard on December 7, and will be looking to line up several other neighborhoods.  Later, after the New Year, we'll continue with a few more neighborhoods and hopefully start up with the Dallas Mavericks' Trees For Threes plantings.  But there's even more which we can catch up on later.

This is much better than chasing bulldozers knocking over mature trees any day.
