Fusiform rust, a fungal disease caused by Cronartium quercum f. sp. fusiforme, is the most damaging disease of slash and loblolly pines in the southeastern United States. There are currently over 60.3 million acres of slash and loblolly pine timberland in the Southeast, some of the most productive forests in the world. Forest managers rely on continued fusiform rust risk monitoring to choose which slash and loblolly pine stock to plant to avoid losses from the disease.
Newly published findings based on U.S. Forest Service Forest Inventory and Analysis (FIA) data show that though fusiform rust levels in slash and loblolly pine stands in some areas are lower than observed in the 1980s, in other areas the incidence of rust has changed very little in the last 30 years.
In 1972, annual South-wide losses from fusiform rust were estimated at around $28 million. Since then, millions of research dollars have been spent developing methods to select, breed, and outplant rust-resistant slash and loblolly pine stock.
Part of this effort included developing hazard zone maps for both slash and loblolly pine based on the analysis of FIA data. Published in 1997 in a report by Forest Service researcher Dale Starkey, the maps were widely used by forest pathologists, tree improvement specialists, and forest managers to make decisions about which planting stock to use on their lands.
As a result of decades of effort, productivity on pine plantations has doubled from what it was in 1940, and there’s been some evidence that rust incidence and tree mortality from the disease has been greatly reduced in areas once deemed “high hazard,” and especially on commercially owned lands where the best available genetic sources of resistance to fusiform rust have been planted.
Prompted by questions and statements from the field, KaDonna Randolph, research mathematical statistician with the Forest Service Southern Research Station FIA unit, was asked to update Starkey’s rust hazard maps using FIA data and evaluate changes in regional rust incidence between the late 1970s and the early 2010s.
Through the analysis of FIA data, Randolph and fellow researchers Ellis Cowling and Dale Starkey found that despite some decreases in fusiform rust incidence over the last 30 to 40 years, rust hazard remains high throughout much of the southeastern United States. They also found that rust incidence was about equal in planted and natural loblolly stands but was higher in planted versus natural stands of slash pine.
The results for slash pine were surprising. The reasons were unclear, but one reason may be the origin of planting stock, which was unknown and may be highly variable in terms of rust resistance.
Data from the analysis was used to update Starkey’s 1997 disease risk maps. The updated maps are included in the article and can be used to guide the planting of rust-resistant stock appropriate to specific areas.
“Because rust hazard remains moderate to high throughout much of the southeastern U.S. for both slash and loblolly pines, continued deployment of rust-resistant seedlings is recommended,” said Randolph. “It’s also necessary to continue rust research and monitoring programs so that the gains in genetic resistance achieved so far are not lost.”

The essential elements of any landscape are trees. Trees are a long-term investment and also the longest living plants that we can grow in our garden. A healthy tree can live up to centuries if it is provided proper protection and is not harmed externally. However, it is so important to choose the right tree for the right place. If a tree is planted in a place where it doesn't fit in, it will devalue your property rather than putting any value to it. This is why it is essential to know why and where you are going to plant a tree.
Choosing the Right Tree:
Many people follow the approach of buying a tree first, coming home and then deciding where to plant it, which is a very wrong approach. You first need to make a complete survey of the place where you want the tree and then determine why you need it there, only then can you choose the right one. You cannot call a tree “superior” in-breed than the other. There are hundreds of excellent varieties out there to choose from. Hence, after you have decided which tree you want at what spot, move on to getting a soil checkup to determine if that specific breed can grow well in your garden. Once you have gone through this process, you can go and purchase the tree you want. Following are a few types of trees:
1. Green Ash
Green Ash is known to be very vigorous when young and eventually grown a broad crown as it matures. This tree is particularly strong and can grow in a number of soils and is also drought-resistant.
2. Red Maple
Red Maples is a tree that sings of spring. As soon as the spring spreads through the air, it starts to produce red, beautiful flowers. This tree is also the first to signal the start of fall, as it changes its colors.
3. White Oak
It is said that a full-grown White Oak is one of the most majestic of the trees. They have sturdy and thick horizontal branches. It grows slowly, but handsomely.
1. Black Gum
One of the most beautiful tree species Black Gum has colors of scarlet and orange in fall. It is also extremely dense and lustrous green, with stiff, leathery leaves. The pros of planting this tree is the fact that it grows very fast.
2. River Birch
River Birch is known for its unique bark, which is salmon colored and comes off in thin layers. Eventually, as the tree matures, its bark becomes dark gray as well as scaly. Many people avoid planting River Birch because of its white birches.
3. Lacebark Elm
This tree is among the best ones for landscapes. They are durable and have beautiful barks. Its exfoliating bark is usually grey, with brown, green and orange underneath, but can vary in colors as well.
1. Japanese Maple
This small tree, or shrub as called by some, is grown because of its unique foliage. It has many different types however the ones that have beautiful red foliage are the most popular. For the best growth of this tree, a soil is rich as well as well drained is required.
2. Amur Maple
This is another smaller species of trees, which is extremely hard, short and round headed. Like many other maples, this tree develops bright red color during fall, which looks gorgeous. This tree has an extraordinary ability to grow in wet soil. However, it also can be grown in drier places.

Believe it or not, this week marks the 20 anniversary of the bombing of the federal building in Oklahoma City. One notable survivor of that fateful event is an elm tree which sat in a parking lot across from the Murrah building, and which is now the centerpiece of the Oklahoma City National Memorial and Museum. The following link is a short NPR interview with Mark Bays, the Oklahoma State Urban Forestry Coordinator, who played an important role in the tree's stewardship and survival.
As leaves bud out, a vibrant green envelops us. As the green comes to you take a deep breath and internalize the brilliance of green. The Chinese refer to the spring as part of the Wood Element, and the associated color is green. According to traditional Chinese medicine the seat of the wood element within the human body is the liver and gall bladder. While that connection is not intuitive to the western mind, I enjoy the connection because it gives me a way to incorporate that green within my body. You may also bring the green into what many know as your third eye, a place just above the bridge of your nose and between your eyes. The third eye is a place you bring not just the color green but the full multi dimensional energy of green including its smell, sound, touch. It is here that you can access it in the dark of night or other moments you choose to access it to be further enveloped in green. Last year, I shared the following about spring green.
Spring overwhelms me. I attribute this to trees coming out of dormancy with such vibrancy. It is difficult not to notice the curtain of green envelop you, particularly on wooded lots. The green is not just overwhelming in color, but also in volume. Once wide open views become views into the color green and your vista contracts from expanse to the tree nearest to you. In the southeast, we are often exposed to this shocking transition in our surroundings as the Southeast has many, many, deciduous trees. This in opposition to the wide open vistas I grew up with in the West, so it is not surprising that my initial reaction to the spring tree phenomena is one of being closed in upon. However, having lived in the southeast for 20 years, I have been able to temper this initial reaction with one of wonder. The wonder of green, of a tree's abilities to spring forth such massive amounts of energy, and simply the wonder of trees. The contraction also has the affect of turning your spirit back towards you, creating a feeling of introspection. Trees shade us, but also impose their wills into the space around us in the form of leaves and green. It is as if a waterfall of green spouts out of nowhere and immerses you into it as if you were swimming in a lake. I take this annual rite for what it is, and try to swim and splash within it without the panic of losing the vista around me.

We know it can be tempting to take care of much needed tree pruning on your own. Often, we just hire the guy down the street that's "handy with a chainsaw". Who doesn't want to save some money? Problem is, poor "cheap" pruning can permanently ruin the look of your valuable trees and often leave them susceptible to storm damage, disease and ultimately decline and death. Here are five of our top common pruning and trimming mistakes we see on trees around the DFW area.
Park Pride of Atlanta hosted a conference this week at the Atlanta Botanical Garden with keynote speakers Peter Harnik, Director of the Trust for Public Land's Center for City Park Excellence and Cynthia Nitkin, Senior Vice President at Project for Public Spaces.
These articles by the Saporta Report summarize the conference theme, Parks and People.
Parks can ignite growth in cities
by Maria Saporta
As more people move to the City of Atlanta, having quality parks is key
by Saba Long
Examples of the latest techniques in park building were discussed, including the Atlanta Beltline. (Another great example is Ellis Square in Savannah, a park on top of an underground parking garage.)
In her presentation, Cynthia said the key to having a great park is offering food, free wi-fi, seating and shade.
I cant wait to see this. I might even have to visit NYC for a first hand experience.
"In the first broad-scale estimate of air pollution removal by trees nationwide, U.S. Forest Service scientists and collaborators calculated that trees are saving more than 850 human lives a year and preventing 670,000 incidents of acute respiratory symptoms."
This is an interesting read from Rolling Stone on the impact of climate change to our forests. Its not a very rosy picture. 25% of the worlds land surface is covered by forests, which are great consumers of the carbon we produce. Increased mortality from heat stress, drought, insects, fire, urbanization can be expected as we move towards mid century. It becomes a clear imperative that we protect and enhance our urban forests.
I am tired of trees being removed for no reason. Trees are the anchors of mini ecosystems that are irreplaceable in our lifetime, yet we choose to obliterate them at the whim of the latest fad in home building. I do not hold just builders and developers accountable, but ourselves as well. How many of us would allow the destruction of trees for a price? Often we are given the false choice of trees or new home. I know this to be a false choice, trees can be built around, it is called a basement or even better elevate the home above the critical root zone. The foot print of a home is flexible, so why do we insist on building in a way that is destructive to the trees? We could be selling forest front homes, but instead too often we choose to wipe the land clear of any living soil and topography. Trees on residential lots need to be protected, we need to make it happen. I argue that the quality of living will be higher around the trees plus we will be preserving a diminishing resource, a micro native ecosystem in the Urban Area.
Most municipalities were rezoned 30 years ago to accommodate what was important back then, building higher density along through fares. Lets rezone using tree ordinances and restricting the removal of trees in new construction. If we cannot protect forests in our urban areas,is it fair to ask to have them protected in the Amazon. Often we feel hopeless in the onslaught of global warming, well here is your chance to have your voice heard in your local area. Ask to protect your local trees through stronger tree ordinances, where tree removal is the exception and not the rule.
I think the grove should host a North American Tree of the Year Competition!
Urban Trees make a difference across the Nation. Over the next 50 weeks, we will be sharing one story from each state. We'll start with Alabama.
Alabama Tree Recovery – Offering Hope and Restoration for Tornado Victims
Many homeowners in Alabama can now look out their windows or down their city lanes, and see small trees growing toward a much fairer leaf-adorned sky. However, they remember the darker days, the devastating winds and toppling trees. The Alabama Tree Recovery Campaign is a story of restoration and hope, of many volunteers and organizations working together to replace trees torn and destroyed by violent winds.
In the months following April 2011 when dozens of tornados ripped across Alabama, the Alabama Forestry Commission joined forces with the Arbor Day Foundation to begin a multi-year, large-scale initiative to restore trees to the stricken communities. Through the Campaign, over 60 communities in 24 counties received seedlings and assistance in replanting their lost urban forest. After its third and final year of distribution and planting, more than 85,000 native tree seedlings of more wind resistant species will be in the ground, growing to replace those lost to catastrophic winds.
Although Alabama Forestry Commission employees and Arbor Day members delivered the seedlings, the number of trees would not have been planted without countless local volunteers and homeowners who applied their own sweat equity and learned the proper way to locate and plant trees. The campaign was made possible by financial contributions from individuals, private foundations, and corporate sponsors across the nation and globe including Alabama Power Foundation, Apache Corporation, Australia-based Cotton On Foundation, Daniel Foundation of Alabama, Davey Tree Expert Company, FedEx, NASCAR, and Protective Life Insurance.
In the words of one resident, “The outpouring of volunteer energy following the storm needed to be matched by an outpouring of goods and ideas. One such match was certainly the Alabama Tree Recovery Campaign. In addition to local donations, [it] helped provide the first signs of hope to our area. I describe the transformation of Tuscaloosa as running from devastation immediately following the storm, to desolation as the debris was removed and the loss and emptiness became more fully apparent. The arrival of new trees into yards where houses were being rebuilt and onto lots where the future was, and even now may remain uncertain, brought back dreams and hope…. The trees symbolize perfectly the progress we make as a society to create vast and wonderful improvements to our lives, a process which takes vision and work over time. I appreciate the resources the Tree Recovery Campaign has provided to the process.”
Another resident noted, “It was remarkable to hear the many associations that people had with their trees. They would say how they miss the shade their trees gave during the summer, how much hotter their homes are and how much more expensive it is for them to run the air conditioner. ... How they missed the birds and wildlife that used to come to their yard, but they haven’t seen after the storms. How they were surprised at how much more water runs off their property and practically floods their streets, and how fast the rain water flows and washes away areas of their yard and driveway. It was amazing to hear the many memories people had associated with their trees and their emotional ties to those trees: kids playing and climbing on them, feeders and art hanging from them, photos of families (generations, even) that were taken underneath them.”
While the cleanup and rebuilding in these communities will continue for years to come, the opportunity to support the Alabama Tree Recovery Campaign remains. For every dollar donated, a seedling will be added to those already planted and help in the healing process.
