Sun scald on ash bark Slugs sheltering in a sun scald fissure When sun scald appears on trees it is most frequently a result of reflected light off the snow during winter months. The damage in this case will appear as sunken or dead bark on the trunk of the tree, then later in the tree's life the bark might fall away revealing dead tissue in ...
Even a deciduous tree can suffer injury or death to part of the root system if conditions are too dry in the winter. Damage may not be noticeable at first, as the tree uses stored food energy to ...
Frost crack or Southwest canker [1] is a form of tree bark damage sometimes found on thin barked trees, visible as vertical fractures on the southerly facing surfaces of tree trunks. Frost crack is distinct from sun scald and sun crack and physically differs from normal rough-bark characteristics as seen in mature oaks , pines , poplars and ...
Marcescence is most obvious in deciduous trees that retain leaves through the winter. Several trees normally have marcescent leaves such as oak ( Quercus ), [ 5 ] beech ( Fagus ) and hornbeam ( Carpinus ), or marcescent stipules as in some but not all species of willows ( Salix ). [ 6 ]
Rabbits and rodents can cause injury to the thin bark and twigs of young trees. When snow covers food sources normally sought during winter, these animals often move into home lawns in search of food.
I scanned the trees and saw that a maple tree had "exploded". The explosion caused a big crack in the tree about three feet high. When a winter wind stirs the frozen trees, they sometimes appear to burst vertically. When it was 40 degrees below zero at night, I lay awake and listened to the trees explode. That's a true wilderness thermometer!
The disease can affect every part of the tree, from the fruit to the trunk. [14] Infected trees may die within months or can linger for years with severely reduced yields. In addition to the scorched appearance of the plant parts that gives the disease its name, plant tissues infected with the bacteria will exude milky or reddish-brown ooze.
