One frustrating thing about tree infections and diseases is that they are virtually completely unpredictable. It is essential to understand all the different types of risks and causes that can contribute to these issues in an attempt to understand how you can try and prevent and manage these things when they happen. Five Star Tree Services is going to go over the reasons as to how and why your trees can develop these certain issues. Since there are so many different causes behind why a tree’s development might be interrupted, first think of them as two different categories you can split them into; non-living factors or abiotic, and living factors or biotic. We also want to note that it is possible for more than one factor to affect a tree’s health and development at any given time. You can also make a distinction between primary pests and secondary pests. The primary pests exert a serious influence on the tree’s immediate survival. Whereas secondary pests have a less significant influence on the survival of the tree. The only time they will jeopardize a tree’s survival is if the tree has a previous debilitating issue from another risk factor. For an individual tree’s circumstances, this will distinct the chances of an infestation, especially if it has any past debilitating issues. Which can be seen from any compromising management practices or pre-existing issues which affect the tree’s development as well as lower its resistance to infections. Poor management in planting is a very common predisposed factor that compromises a tree’s infection defense. For instance, any saplings that are pot-bound will not get to develop solid root systems which doesn’t allow them to develop properly when they eventually get planted. Another example is when a tree gets stressed, along with other outer factors, will have significant effects on the overall wellbeing of the tree and its condition. Other factors to consider are bad soil quality as well as bad drainage. Abiotic Non-Living Influences The overall health of a tree can be linked to impacts such as bad growing conditions and bad soil quality. These things will put trees at a higher risk for catching a number of different biotic issues. Sickness, infections, and infestation can all be linked to ineffective nutrient absorption when a tree has insufficiently developed its natural resistances and defenses. One of the worst factors for this is fire damage. It is so debilitating that it makes trees hopeless at defending themselves against biotic attacks. To uncover what circumstantial predispositions your tree might have due to poor developmental conditions, arborists can use the growth rings as a means of assessment for the long-term effects, wellbeing, and growth of a tree. There are many outer and non-living variables that will influence the health of a tree and if it will be predisposed to biotic infestations. Such variables can include things like extensive cold winters and long dry spells. Abiotic Common Influences Include: -Water -Chemicals -Soil Conditions -Weather -Mechanical Agents Biotic Living Influences Sometimes, you are able to notice certain infestations easily, while others can be hard to tell. For instance, seeing an insect on a tree is no cause for alarm. A lot of them are harmless to the tree and do not cause harm while they regularly feed. However, some insects are actually harmful to a tree’s survival and knowing the difference between harmless and harmful ones is what you need to notice. You might also see fungi on rotting matter or a dead tree. Fungi are not usually the immediate influence of a negative manifestation found in a tree’s development. There are other growths that can be seen living on trees. These include saprobic and pathogenic organisms. Saprobic growths are mostly found on rotting or dead tissues and pathogenic growths are less common. Some other living infestations include lichens, epiphytes, and mosses. But these don’t usually have any effect on a tree’s wellbeing. They live symbiotically together. Biotic Common Influences Include: -Mites -Deer and Rodents -Fungi -Weeds -Viruses -Parasitic Plants -Bacteria -Phytoplasmas -Insects How Five Star Tree Service Can Help It is important to know the basics to look out for when trying to prevent developmental issues or help a tree that is developing.
