Tree and Brush Removal Laws Vary by State and City

The laws surrounding tree and brush removal can be complex and sometimes difficult to understand. Laws vary between states and even cities, largely because of the wide variety of climates that occur across America and because of the important role that trees and brush play in local ecosystems.

Arborwell Professional Tree Management provides arborist and tree maintenance services for commercial properties, estates, municipalities and HOA’s and we are well versed in local laws concerning the removal of trees and brush. We can help you to navigate these laws and get you the permits you need to continue developing your property.

Why are tree removal laws so different?

Tree and brush removal laws are varied based on location because of different environmental factors and needs. In California, there are strict laws regarding vegetation within 100 feet of structures. The law states:

  • The first thirty feet from a structure must be clear of all dead plant material.
  • Tree branches must be ten feet from chimneys and other trees.
  • The last seventy feet must focus on fuel reduction, meaning lawns should be mowed regularly and areas underneath trees should be clear.

These laws aim to improve wildfire safety by reducing the chance of buildings and structures burning down. In places like Seattle, trees and brush play an important role in the ecosystems so laws revolve around retaining vegetation:

  • There are limits to the number of trees you can cut down.
  • You need a permit to remove non-native or invasive vegetation and plant native species.
  • You need permits to remove trees and vegetation in landslide prone and steeply sloped areas.

These are just a taste of the differences in tree and brush removal laws in California and Seattle. Before you go ahead with your property development be sure you are aware of your local laws and the permits you need to obtain!

common tree diseases

Arbor-wellness: Bacterial Leaf Scorch

I’ve been told my oak trees have bacterial leaf scorch, what is that?

Bacterial Leaf Scorch is a devastating disease of shade trees caused by a bacteria. The bacteria themselves live inside the tree’s water conducting tissue. They “cluster” inside the water transport tissue and essentially block water transport, which leads to the scorch symptoms.

The disease will slowly progress throughout the tree for up to a decade causing dieback and eventually killing the tree.

What trees are affected by it?

Symptoms and damage are usually most visible on pin and red oaks, but shingle, bur and white oak can be affected as well. It can infect elm, sycamore, mulberry, sweetgum, sugar maple, and red maple.

How does it spread?

Insects like sharpshooters, treehoppers, leafhoppers, and spittlebugs spread the bacterium from one tree to another. These insects feed on the xylem tissue and will inoculate the tree if they carry the bacteria with them.

Can you treat for this?

It is best to treat before the tree has Bacterial Leaf Scorch or in the early stages of it. Your Arborwell Arborist can develop treatment plans after determining the scope of the problem on your site. They can determine if preventative treatments or early curative treatments are required. If certain pests are prevalent, treatment to prevent their establishment may be recommended.

Also remember that a stressed tree will develop symptoms faster, so keeping trees properly watered and mulched are another way to help reduce the spread of this disease.

If you are concerned about bacterial leaf scorch, or other problems on your trees, contact your Arborwell arborist to help you create the most effective management plan for them.

Arbor-wellness: Cherry Bark Tortrix

What is the Cherry Bark Tortrix?

The cherry bark tortrix, is an introduced caterpillar pest in western Washington  and from British Columbia south to parts of Oregon coastal areas. It is found mostly on cherry, plum, and apple; but may also be found on peach, crabapple, pear, hawthorn, mountain ash and quince.

Why do I need to worry about it?

It is a growing problem in our area. It can kill trees outright through girdling the trunk. Typically, though, heavy infestations around the graft lead to dieback above the graft. The stress associated with an infestation can leave trees susceptible to secondary disease and insect problems.

How does it spread?

Cherry Bark Tortrix is a smaller moth, whose caterpillar stage does the damage inside the lower tree trunk. They overwinter in the trunk and emerge in the mid-late spring time frame. The adults lay eggs in cracks and wounds in the bark area in late summer. Large populations will kill the trees as they girdle around the tree. Initial infections will stress the tree and often cause a gummosis that exudes from the bark.

What is the best way to treat it?

Protection from these late summer infections is usually the best proactive treatment, but spring systemic treatments are also effective and should be considered if you are concerned about this pest. Your Arborwell Arborist can insect your trees and determine a treatment plan. Typically they include a treatment to suppress any existing problem, then an annual proactive treatment to prevent further infestations. Proper tree health is also important, so they may recommend nutritional feeding and corrective pruning if needed.

If you are concerned about cherry bark tortrix, or other problems on your trees, contact your Arborwell arborist to help you create the most effective management plan for them.

Arbor-wellness: Leaf Spot

I see dark spots on my maple leaves and many of them are falling off. Is this a problem?

Your maple probably has a type of leaf spot disease. Leaf spot is a term used to describe a wide variety of diseases affecting the leaves of ornamental and shade trees. The majority of leaf spots are caused by fungi, but some are caused by bacteria. Leaf spots on trees are very common. They often result in some leaf drop. When the leaf drop is severe, your trees can be at risk of suffering damage until they recover.

How does it spread?

Most spread by rain or water splashing on their leaves. They often overwinter on fallen leaves, so leave removal in the fall we reduce many of these diseases. There are many different leaf diseases and some require fairly specific treatment, so having a professional help identify a management plan is critical.

How do they affect tree health?

If you think of a tree as an energy factory, the amount of leaves and the time they stay on the tree greatly influence the amount of energy they produce and store throughout the year. (Think photosynthesis.) when a tree loses the majority of its leaves from a leaf spot disease, the tree cannot store enough energy over time and becomes more susceptible to other diseases or insects.

Can you treat this disease?

Yes, in cases where significant damage is expected, treating either before or during the infection is appropriate. Preseason protection is always the best, but options exist for treating early before the disease becomes widespread too. Typically, some nutritional feeding is recommended to help the tree recover from the stress of these leaf diseases.

What else can I do?

Some slight changes in how you care for your trees can help reduce the incidence of leaf diseases. Proper pruning to keep the canopy open is the first step.  Avoiding overhead watering on the foliage is another important step. Keeping your trees healthy is also important. Be sure to fertilize correctly, though. At Arborwell, we use a nutritional feeding program that is proper for your trees and your soil conditions.

If you are concerned about leaf spot or other problems on your trees, contact your Arborwell arborist to help you create the most effective management plan for them.

Arbor-wellness: Pink Rot

What is Pink rot?

Pink Rot is a disease that attacks weak or stressed palm trees. Because palms cannot repair wood tissue, they are more susceptible to diseases like pink rot when damaged or pruned too severely. It can attack any portion of the palm, including the trunk, but it most often affects new growth.

What palms does it attack?

There are a number of palm trees that are susceptible to Pink rot. We mostly see it on Washington fan palm, king palm & queen palm.

What should I do about it? 

Because there is almost always an underlying cultural problem that encourages pink rot to develop, you should try to determine that and correct the problem if possible. We can help to determine that, by the way. The underlying problem could be planting incorrectly, watered improperly, poor drainage, poor nutrition or even just the wrong palm for the site. It is important to avoid wounding a palm trunk, so even nailing something to the trunk or climbing a palm with tree spikes is not beneficial. Where it is possible to correct one or more of the above problems, it will create a longer-term solution for palm rot problems.

Can I treat the palm if it has Pink rot?

Yes, there are treatments for pink rot if the disease has not progressed too much. Treatments should begin as soon after discovery of the disease as practical. This includes a systemic treatment applied to the soil and regular fertilization with a palm specific fertilizer. Also, steps should be taken to change the conditions that are reducing the health of the palm tree.  It is important to remember that if the underlying problem is not improved, there will be an ongoing need to treat the palm and it may eventually fail anyway.

If you are concerned about Pink rot or other problems on your palm trees, contact your Arborwell arborist to help you create the most effective management plan for them.

Arbor-wellness: Tussock Moth

What is a tussock moth and why are they so damaging?

There are many types of tussock moths that all have distinctive clumps of bristles on their backs of the caterpillar larvae. The adults are usually a smaller dull brown or white moth. The damage is done by the caterpillar – which are voracious eaters of foliage with the capability of defoliating entire groups of trees. On the west coast the most important species are the Western Tussock moth, the Douglas-fir Tussock moth and the Pine Tussock moth.

Why are they so numerous?

Most caterpillar species like the tussock moth go through population swings, building up a population level for several years, then seemingly disappearing for several years before returning in large numbers again. The presence of predators of these pests plays a large role in those population swings. For the Tussock moth, the overwintering cocoon in the trunks of trees can help indicate the potential of a population outbreak.

Are there safe methods of keeping their population low?

At Arborwell, we strive to find the safest, most effective solutions to pest problems. For the Tussock moth and other caterpillars, we use a commercial version of a biological suppression product that is effective on caterpillars. This fits most LEED and organic type programs. Timing is very important to be effective so often we recommend two or more treatments in a given year. Preventative treatments are available that work inside the tree – eliminating the need to spray the canopy of the tree.

If you are concerned about Tussock moth or other caterpillar problems in your trees, contact your Arborwell arborist to help you create the most effective management plan for caterpillar damage on your trees.

Large Tree Care Challenges

The Challenges of Large Tree Care

A large, well established tree can present many challenges that the average person may not be aware of. Arborwell Professional Tree Management has ISA Certified Arborists that know how to address the needs of mature trees and can help you maintain these beautiful works of nature.

When it comes to large tree care, trust Arborwell to keep your trees healthy and looking their best. We know the challenges they can pose, and our experts have the experience to care for your trees.

Tree Trimming Is Crucial

With larger trees always keep in mind your local tree requirements. Trees must be trimmed to a certain distance from sidewalks, driveways and especially electrical lines. If a tree is planted too close to these things and it can’t be fixed through trimming, it may need to be moved to a new location. Our arborists in your area can educate you on local requirements and what options are available.

Its also important to know that mature trees require regular trimming to get rid of dead branches, diseased areas and to make room for new growth. With larger trees, it is vital to maintain the weight of branches. Trimming can help to avoid snapping and breaking of larger branches. Arborwell arborists know how to properly trim trees so they stay at optimal health.

Be Smart with Water Use

There is a big difference between the water needs of young trees vs old trees. While a young tree needs frequent watering as it is growing very quickly, larger trees benefit from less frequent, yet deep and soaking irrigation. The best form of irrigation for a large tree is soaker hoses, which provide slow watering. Speak with our arborists about what type of irrigation is best for your tree.

Be Vigilant about Pest Control

Large trees have much more foliage than smaller trees and it can take longer to notice pest infestations. Because larger trees grow much slower and it can be more difficult to identify pests, there is a greater chance of devastating infestations. Our arborists know how to identify and prevent pests from damaging your trees.

Choose Arborwell For Your Large Tree Care Needs

Arborwell Professional Tree Management knows how to take care of your mature trees. We know that larger trees can have a unique set of challenges and we want to educate you on how to properly take care of them. Call us today at 888-969-8733 or click here to visit us online and request an estimate.
