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 . [6] All oak trees may display foliage marcescence, even species that are known to fully drop leaves when the tree is mature. [ 7 ]
However, plants have their own ways to survive a fire event or recover after a fire. The strategies can be classified into three types: resist (above-ground parts survive fire), recover (evade mortality by sprouting), and recruit (seed germination after the fire). Fire plays a role as a filter that can select different fire response traits. [6]
Sassafras trees grow from 9–35 metres (30–115 feet) tall with many slender sympodial branches and smooth, orange-brown bark or yellow bark. [7] All parts of the plants are fragrant. The species are unusual in having three distinct leaf patterns on the same plant: unlobed oval, bilobed (mitten-shaped), and trilobed (three-pronged); the ...
These ecosystems had the highest fire frequency of any habitat, once per decade or less. Without fire, deciduous forest trees invade, and their shade eliminates both the pines and the understory. Some of the typical plants associated with fire include yellow pitcher plant and rose pogonia. The abundance and diversity of such plants is closely ...

As the trees grow taller in denser forest, they lose their lower branches, such that the foliage may start as high as 34 m (110 ft) off the ground. [19] Douglas-firs in environments with more light may have branches much closer to the ground. The bark on young trees is thin, smooth, gray, and contains numerous resin blisters.
Pruning and treatment dots also give a heads-up to property owners near the trees. This way, when the city notifies them of an upcoming pruning or treatment, they know which trees will be affected ...
Various animals can girdle trees through their feeding or others activities. In North America, trees are prone to damage by voles in particular girdling both their roots and trunk. [10] Among North American birds, the sapsuckers are the most common girdlers of trees. While sapsuckers will bore holes in tree trunks to feed upon insects, they ...
