Sudden Oak Death (Phytophthora ramorum) - SOD (also known as Phytophthora canker disease), was originally identified in Germany and The Netherlands in the early 1990's on Rhododendrons . Since being discovered in the United States, it has been confirmed in forests from California, Oregon, Washington and British Columbia. The origin geographically of Phytophthora ramorum is unknown and before the early 1990's there were no reports in Europe or the United States. The areas that do exist in Europe and the United States are believe to have been originally transported from other areas or even the original site of origin. Phytophthora ramorum's very limited distribution related to the host's distribution suggests a more recent introduction versus a point of origin.

Two types of disease are caused by Phytophthora ramorum, the first being bark cankers and the second being foliar blights. Bark cankers may eventually kill the host while foliar blights serve as a reservoir for the pathogen to remain within and be tranferred from the foliar host. The list of hosts (and foliar hosts) seems to grow with each new report and now includes Coast and Canyon Live Oak, Tanoak, California Black Oak, Coast Redwood, Douglas Fir, Rhododendron, Bay Laurel, California Buckeye, Madrone, Bigleaf Maple, Oregon Myrtle, Toyon, Honeysuckle, Arrowwood, Camellia, Californis Hazelnut, Mountain Laurel, Valley Oak, Poison Oak and Grand Fir. In lab testing it has been found that both Red and Pin Oaks are susceptible this opens up the potential for spread into the Eastern portions of the US as the Red Oak family is found in most of North America. In the field the White Oak family including the Valley, White and Blue Oaks have not been confirmed as hosts or even shown any symptoms- hopefully this means they are immune to Phytophthora ramorum or at least have a higher tolerance level.

As with many diseases of woody plants the spread of Phytophthora ramorum most likely occurs from contact with foliar hosts, infected material, soil transfer and spreading by rainwater. Windy, cool and moist conditions are also thought to aide in the spread of the pathogen by further dispersing the spores from their foliar hosts. Transporting (for nursery sale, wholesale or production) of foliar hosts may also aide in the spread of this disease making it harder to control.
The symptoms of Sudden Oak Death are easily identified by large cankers on the trunk or main stem, browning of the leaves or even death of the entire plant/tree. Some infected trees also become host to Bark or Ambrosia Beetles, or Sapwood rotting fungus-these outside organisms may speed up or even contribute to the death of the host. Foliar host infection os harder to identify and may not be noticed until it is to late. With a foliar host you may notice deep gray or brown lesions on the leaf blades, vascular tissues, petiole, or stems of the host.

The Arbor Day Foundation has been working for 20 years to perfect the Hazelnut and create a superior variety that not only produces delicious and nutritious nuts but also offers disease resistance and tolerance of the wide range of growth conditions the United States provides. In 1996, The Hazelnut Project began with nine acres and the planting of roughly 5200 juvenile bushes made up of 60 different hybridized Hazelnuts near the Lied Lodge at The Arbor Day Farm in Nebraska. By 2005 they had gained assistance from more then 50,000 charter patrons nationwide who had agreed to plant, observe and report progress of their own bushes. By 2012 new seedlings were propagated using a combination of the best performers from the originally distributed plants, patron grown nuts and even some plantings found in the wild. Now in 2016, there is hope that even better hybrids will continue to develop over time and the plants will be become stronger and more hardy.

Hazelnuts are considered by many as a super food, their rich complex buttery flavor allows them to not only be eaten alone but also pair well with many other foods. They are high in dietary fiber, Vitamin E, magnesium, potassium, antioxidants, phytonutrients, and Vitamin B. Studies have found that the consumption of just 1.5 ounces of Hazelnuts per day may reduce the risk of cardiovascular disease. They contain mainly mono-unsaturated fats which are the heart healthy and no cholesterol they are a heart healthy smack. The Hazelnut crops appear in the late summer, replacing the delicate red blossoms.
Hazelnut bushes are considered to be woody agriculture, this means that they help slow climate change by providing oxygen and offsetting the build up of carbon dioxide in the atmosphere. The plants are capable of capturing solar energy, which makes them photosynthetically efficient. They are deep, rapid rooting and can live for up to 80 years. They begin producing crops as early as 2-3 years after planting. Hazelnut shells can be used as a safe and efficient fuel alternative which can lead to a reduced demand for wood and other energy sources.

With what forecasters are calling a possible snow storm of the century just hours from arriving it is a little too late to take those extra steps to prevent possible storm damage to your trees and shrubs. You can however be prepared for how to handle certain situations that may arise after the storm has passed. The first thing to remember is DO NOT try to swat, beat, bang or knock heavy snow or ice off of your trees or shrubs. They may be leaning over or look like they are going to break at any moment but you interefering with Mother Natures "process" will more then likely cause more harm then good, not to mention the risk you take of injuring yourself if the tree should give way and fall on you.....or cause the snow and ice load to fall on you..... It is just not smart either way you look at it so PLEASE don't try it! In cases of small evergreens (Yews, Junipers, Hemlocks, Leylands, etc) and snow (not ice) you can gently brush snow off ot the limbs with a soft broom to help eliminate some of the weight from its branches, again please wait until after the storm has passed.

If your trees are damaged remember, trunks, limbs and branches can in some cases be cabled or braced professionally (if the damage is not to severe). If the damage is too much for cabling or bracing to correct, damaged sections may be able to be cut back to a safe point to save the remaining tree. In cases of severe damage the entire tree may need to be removed entirely and replaced with a more sturdy option (Remember the right tree right place rule if you are replanting!). When trying to determine if a tree is worth saving you need to considered not only the extent of the damage but the extent of the possible repairs and the overall value of the tree itself. If your tree has a small amount of bark that is peeling, ripped or torn after a limb breaks off completely, do not try to cover the wound or repair it. If it is hanging and pulling on the wound causing further damage, you can cut (with clean sharp trimmers) off just the loose/hanging portion, leaving a small portion loose near the edge of the wound (not cutting tight to the wound) be very careful not to pull or peel anything further from the tree. Trees have a natural process (CODIT) by which they heal themselves. Covering wounds or interfering during the process could actually prevent this healing process from occuring.

If your small tree or shrub begins to uproot it may be able to be uprighted and secured with stakes or guy wires. Keep in mind that if more then 1/3 of the roots are damaged you may be fighting a losing battle. Do not try to upright large trees, not with your truck, not with a come-along, and never with a ladder (yes we have seen the results of these attempts ad they are not pretty) - if the tree is too large to be lifted by natural human power then contact a professional and let them lead you in the right direction.

Some tree varieties are damaged more often during storms then others because of inherent structural weakness such as weak wood, weak roots or narrow crotch angles, these include but are not limited to Bradford, Cleveland and Aristocrat Pears, Elms, Poplars, Silver Maples and many common evergreens/conifers. With these types of trees artificial support may be recommended to help prevent crotch or branch splitting or breakage. Of course, it is always best to plan ahead before storms arrive, look up at your trees often to monitor for any changes that may be cause for concern. Remember, trees are living, growing and changing, they require care maintenance and TLC to thrive! Structural damage caused by wind and ice can usually be prevented by careful and through pruning including removing weak/diseased limbs, or limbs forming narrow crotches.
You may reach us during an emergency (24/7/365) via email [email protected] or call our office during regular business hours (410)439-1900. Stay safe if you must venture out during the storm, otherwise stay warm and enjoy the Snow Days to come!

The Asian Longhorned Beetle - Anoplophora glabripennis (ALB) is a serious pest from China, it has made it's way to the United States and has been observed attacking our trees. This beetle's larvae tunnels into trees, causes girdling of stems and roots, repeated attacks can lead to die back usually beginning with the crown of the tree and eventually the entire tree. It is thought that the Asian Longhorned Beetle traveled to the United States inside solid wood type packaging material from China, it has been intercepted at various ports through the country. Within the United States it appears that this beetle prefers trees in the Maple species (Acer), such as Red, Norway, Silver and Sugar Maples and Box Elders. They have also been found on Birches, Buckeyes, Horse chestnut, Willows and Elms.
Photo Citation (Infestation/Tree Damage) Dennis Haugen, USDA Forest Service, Bugwood.org
Photo Citation (Adult ALB) Peggy Greb, USDA Agricultural Research Service, Bugwood.org
The ALB are unique in appearance and quite easy to spot. Adults have a deep black bodies with white spots on the back. They are 3/4 - 1 1/4 inches long and have very long antennae that are usually 1 1/2 - 2 1/2 times the actual length of their bodies. The antennae are clearly marked by white bands or stripes on each segment. The egg laying sites within a trees bark is generally oval or round and are chewed out by the female beetle before she deposits a single egg into each. Some trees- Maples most notably, will ooze sap from the egg laying sites as the larvae feed inside during the summer months. Around the base of infested trees there will be an accumulation of coarse sawdust usually found at the point where the branches meet the trunk, this sawdust is caused from the larvae boring into the tree, stems and branches. When the adult ALB finally exits the tree it leaves a large round hole that is about 3/8 of an inch in diameter on branches or trunks. ALB only have one generation per year and adult beetles are usually only found from July - October. A female can only lay 35- 90 eggs in her entire lifetime and eggs can hatch in 10-15 days. The larvae will live under the bark and continue to feed within the tissues of the tree, they then bore deep into the tree to pupate. The adults emerge from pupation sites by boring tunnels in the wood and creating round exit holes.
Photo Citation (Entrance and Exit Wounds) Dennis Haugen, USDA Forest Service, Bugwood.org
Currently in the United States the only way to eliminate the pest is to remove infested trees and destroy them by chipping or burning of the material. There are many quarantines in effect around the country to help prevent further spread of the insect (and other insects). As with most pests early detection is the best defense allowing for rapid treatment/removal, this is the only way the pest can be truly eradicated from an area.
If you suspect that the Asian Longhorned Beetle is in your area it is asked that you collect an adult beetle in a jar and immediately notify officials in your area. You can contact your State Department of Agriculture, Forest Service, State Forester, Department of Natural Resources, or State Entomologist. You can also call toll free to 1(866)-702-9938 .

The National Big Tree Program
Amy: Posted on Monday, February 09, 2015 2:50 PM
The National Big Tree Program began with an article in the September 1940 issue of American Forests magazine, it asked for readers to search for Americas largest trees. Joseph Sterns, a concerned forester wrote the article called "Let’s Find and Save the Biggest Trees" requesting readers to not look at the obvious but find the giants standing quietly in the forests and on virgin lands.
American Forests has maintained the National Register of Big Trees since that date. The Big Tree Program is active in all 50 states and Washington DC and is used as a model for several Big Tree programs around the world. The National Big Tree Program has been promoting the same message for over 70 years: regardless of size, all trees are champions of the environment.
Important milestones for the National Big Tree Program:
1940 – The first tree is nominated: a Chestnut Oak in Suffield, Connecticut.
1941 – The American Big Trees Report is launched with a total of 77 champions.
1961 – The program name is changed to the Social Register of Big Trees.
1969 – The first Hawaiian edition of the register is published.
1978 – The publication changes its name to the National Register of Big Trees.
2010 – The National Register of Big Trees launches the first online publication of register.

Ideas to help you celebrate Arbor Day
Posted on Friday, April 27, 2012 9:45 AM
Happy Arbor Day!
Below are some suggestions from www.arborday.org on how to
celebrate this special day!
So, Get out there and start digging! Remember you are planting for our future!
Raise the flag, strike up the band, make Arbor Day fun. Make it memorable.
Organize a beautification project in a public area.
Get people into action. Ask a civic or service group to promote a paper drive to gather paper to be recycled and save a tree. Use the proceeds to buy a special tree to plant in a park or other special public place.
Hold a poster contest, or a poetry contest.
Sponsor a children’s pageant or play.
Fill the air with music. Have an Arbor Day concert of songs about trees, or with tree names in their titles.
Sponsor a tree trivia contest. Give away trees to winners.
Conduct a tree search. Ask people to find large, unusual or historic trees in your community. Once the results are in, publish a map that highlights the winners, or hold a walk showcasing them.
Tell people to take a hike — a tree identification hike — and have girl scouts or boy scouts act as guides.
Dedicate a forest, or a tree, or a flower bed in a park, and make it an occasion to talk about stewardship. Get a local nursery or garden center to hold an open house or field day. Organize an Arbor Day Fair.
Encourage neighborhood organizations to hold block parties and get their members to adopt and care for street trees in front of their homes. Pass out buttons. Give away trees.
Celebrate Arbor Day in a personal way by planting a tree yourself. It is an act of optimism and kindness, a labor of love and a commitment to stewardship.
Read a book about trees. Learn to identify trees in your yard and neighborhood.
Enjoy the outdoors. Visit a local park or take a nature hike.
Attend a class on tree and plant care.
You’ll meet new people and make a difference in your community.
