Tree Shortage Solutions

Tree Shortage Solutions

A serious shortage of trees has been threatening for some time as building in Florida has continued to boom. It was made worse by periods of heavy rain that destroyed some fields and made others unfit to dig.

This is an astonishing season of sales for the landscape industry in the southeastern United States, the area that I now know best. Advertising of plants in Plant Finder, our associated print magazine that deals with availability, has dropped because a number of nurseries are fully booked for the rest of this year’s production, and installers are having fearful problems locating material for jobs that may have been designed and bid many months before the shortage developed. I am not referring to the fact that specifications by some designers are wildly unrealistic in matching tree canopy size with caliper; that has always been a problem. No, this is a genuine situation in which finding regular, good quality trees means scouring a wide area, and then often having to ask for changes in the specifications of the job.

Shortage of trees is likely to be the most difficult part of the problem to solve. Some municipal landscaping codes have minimum size requirements for any tree to be installed, and are also now beginning to apply quality standards. Florida has taken the lead nationally in establishing a new set of grades and standards for landscape material. The tree standards, in particular, are aimed at installing the safest possible tree, with the best chance of survival, in any job that chooses to specify one of the better Florida grades for the material. This in itself has meant that not all material grown in the state is still suitable for these jobs.

What could be done to ease this situation? One possible answer is to relax the minimum size requirements which many municipalities have in their landscaping codes. The Broward County chapter of the Florida Nursery and Growers Association is suggesting a moratorium on the tree minimum height requirements for a period of two or three years. Trees would still have to meet all criteria laid down in the grades and standards manual with respect to single leaders and other aspects of a quality branch framework, as well as the requirements for root vigor, but could be installed at, say, 8 or 10 feet overall instead of 10 or12 feet. In addition to easing the current shortage this has the added advantage that smaller trees are easier to move and have a better long-term establishment and survival than larger material.

Is there a hope that common sense could prevail here? Landscape inspectors cannot accept smaller sizes without official action to amend the code requirements. Can we explain to city officials who may have very little knowledge of how plants grow or of the realities of the landscape industry, that this is not purely a self-serving request, but one that will keep projects on time, and will have healthier plantings in the long term. It is essential that we insist on the strict quality and safety standards, all that is needed is the change in size requirements. If the nurseries and the installers can explain this to the inspectors, and if together the united group could convince the municipal authorities, the whole situation would become much easier. And, who knows, once everyone has cooperated on this, it might even be the beginning of better communication throughout the landscape industry. Dream on!

Smart Development: Developers are Seeing Green!

Smart Development: Developers are Seeing Green!

After countless stories of developers filling wetlands and bulldozing vegetation, it’s easy to see why arguments often revolve around the environment versus development. Yes, there are occasions when developers replace Walden Pond with yet another strip mall. Development and urbanization have contributed to the degradation of natural systems worldwide, even affecting such distant areas as Antarctica. The demand for a choice between development or environmental protection obscures the fact that both are essential for society. Whether we like it or not, the urban landscape is changing and development continues to occur. The onus is on us, the planners and managers of resources, to strengthen the necessary link between quality or smart development and environmental protection.

Most people would agree that economic development is important for the survival and success of their community. At the same time, they may also advocate policies that promote environmental protection. This situation is complicated as the negative impacts of growth become more obvious and natural resources are depleted at exponential rates. This makes the balance between development and environment more difficult to achieve. “Smart development” or “smart growth” may make finding the balance easier, as the design of communities and the built environment allow natural systems to function similarly to pre-development conditions.

There are many encouraging trends in the nation’s development industry. The Michael T. Rose Development Company uses the concept of “eco-urbanism” in conducting their business. Eco-urbanism is an approach to land use and development that blends human habitat into the natural ecosystem. Recognizing that growth is necessary, eco-urbanism accommodates growth while minimizing land disturbance and maintaining the natural beauty of the land.

Buddy Milliken, a developer in North Carolina, believes that rather than being merely a place to live, work, shop, and play, neighborhoods should function within an ecological system. Milliken clusters development thus freeing land for wildlife habitat, forests, and agriculture. Clustering development also brings people physically closer together and encourages interaction, imperative for a functioning neighborhood.

The yet-to-be developed Haymount community in Caroline County, Virginia is planned with environmental and social goals in mind. For example, the site plan includes details about advanced wastewater treatment, including the use of constructed wetlands and other biotechnical measures. In order to increase sustainable agriculture in the region, Haymount will include a farmers’ market and an organic farm. The 1,600 acre residential and commercial site will have playgrounds and parks in each neighborhood. Native plant species will be used in the landscaping and 70% of the land will be left in its natural state. While examples such as those listed above are occurring at an increasing rate, much improvement is still needed to reconcile environmental protection with development. Presently, many incentives exist to build sprawling development fueled by federal and state highway expansion and guaranteed mortgages for single family houses, but not multi-family or mixed-use development. These incentives often result in low density development that eliminates public open space and natural areas.

Led by Peter Calthorpe and others, many planners advocate environmentally sensitive types of development. Calthorpe argues that nature should provide the order and underlying structure of the metropolis. Estuaries, mountains, and rivers form natural boundaries that can lend a unique character and identity to neighborhoods and communities, however, the building of sustainable communities cannot occur without long-term regional planning efforts. Planning predominately occurs at the local level where regional impacts of development are often ignored. Looking beyond political boundaries is essential in thinking about sustainable development.

Increasingly, the success of environmental protection efforts depends on the level of involvement and sophistication of local government. As the state of the knowledge improves and the causes of environmental problems are identified, it is clear that local government must participate in the improvement of natural systems. As this trend continues, many local governments, understanding the inflexibility of existing regulations, are amending local ordinances to provide developers with opportunities to be innovative and creative.

There is a common misperception that environmentally sensitive development costs more money. As studies have shown, there is actually a savings to the developer to build higher density residential developments. These savings are realized through lower excavating, landscaping, grading, and paving costs, as well as savings in road building, storm drainage and water and sewer service. Similar cost savings are achievable in commercial development as well.

Prince George’s County, Maryland actively promotes an innovative development technique they call “low impact development.” Recognizing the difficulty in complying with numerous and complicated regulations and regulatory agencies as well as the fact that current development practices tend to create the mess and then clean it up, Prince George’s County developed an environmentally sensitive approach to development. Low impact development promotes the preservation of natural resources and the hydrologic function of the site, maintaining water quality, and minimizing site disturbance. The county currently provides developers with opportunities to learn about how low impact development techniques can save time and money through workshops.

In an attempt to promote the concepts of smart growth, the US EPA is in the process of organizing a workshop to highlight cost-effective, best management practices for infrastructure and development. The goal is to reach a nontraditional EPA audience that may not see itself as having a role in water quality issues or in delivering environmental services. Real estate developers, bankers, lenders, and other financiers; architects and landscape architects; transportation, urban, and environmental planners; engineers; port authorities; utilities; and historic preservationists will all be recruited for their participation in this workshop. Announcements with more detailed information will be available in late spring.

While the choice to continue to develop has been made, the type and quality of development is open for debate. Planners and natural resource managers should encourage smart development. By promoting environmentally sensitive development we can save our critical habitats and landscapes and encourage economic development.
