Austrian pine (Pinus nigra) tolerates well both hot and colder temperatures, also drought. This is due to the dense horizontal root system that goes deeper than most Pinus species'. (Magyar 1960) As a tree that feels itself home mostly in continental mountain ranges and the Mediterranean climate, its home range stretches from Iberia through the Alps to the Taurus mountains in Asia Minor. It is medium to fast growing with a pyramidal crown. It is mostly resistant to breakage. (Gilman-Watson, 1994) Despite the contradictory opinions about the species (foresters emphasise on how it prevents soil erosion and the soil shading ability, while ecologists how it suppresses the local flora, invasion capabilities and fire hazards), it's often used for land reclamation, as it has a wide tolerance range in temperature and soil quality as well.
White pine (Pinus strobus) has an intermediate shade tolerance and can live well for many years under the canopy in partial sunlight. The young trees will respond quickly and positively when the suppressive layer is removed. It tolerates many kinds of soils, however it does best on sandy types. (Martin-Lorimer, 1997) It is widely grown

It can reach about twenty meters in height if the conditions are suitable, but might remain shrub sized if they are poor. It likes dry, sandy sites and is highly intolerant of shade, therefore the seeds and the seedlings need full sunlight without any kind of coverage, hence selection cutting and uneven-aged forest management is not feasible. It grows best on fertile loamy sands. If this need of sunlight of theirs is not fulfilled, they might not develop properly, or quite probably no maturation will happen at all. The shape is rarely regular. It can often be found in association with other pines, like the red and white pine, though they should not be mixed. (Martin-Lorimer,

    As a result, it takes about 19 years for the young western hemlock to reach 1.2 m as opposed to 5 years for a non-browsed western hemlock (Vila et al., 2003b). However, despite the deer slowing the growth of the Sitka spruce and the western hemlock, the abundance of these tree species has actually increased since the introduction of deer to the archipelago (Gaston et al., 2009). In contrast, there has been a depletion in young redcedars present in old-growth forests throughout the archipelago, and studies suggest that deer browsing is the reason behind this (Stroh et al., 2008). The Western redcedar is tree species is most vulnerable to high deer densities as it is palatable year round (Stroh et al., 2008). Recently, a study on Graham Island found that under current conditions it could take over 50 years for redcedar seedlings to reach the height of the browse…

    Salt Cedar comes in two main subspecies; ramosissima and chinensis but there are also many forms of hybridized individuals. Tamarisk is a type of dense, shrubby tree that produces tiny pink flowers. Tamarisk trees have taken over 1.5 million acres of wetlands in the western United States (Whitecraft, Talley, Crooks, Boland & Gaskin 2007). They can thrive in a range of soil conditions and tolerate very saline soils. The tree’s tap root will stretch down far enough to tap into the water table, where native plant’s roots cannot reach (Longcore, Rich, & Müller-Schwarze. 2007).…

    In 1920 there was a significant plunge in the rate of growth in this tree’s life. It is known that the Pseudotsuga menziesii is sensitive to drought, thus it could have been one of the many reasons why the growth rate changed dramatically. The decrease in growth continued in 1960 to 1970 where the growth rate was at its lowest. Rocky mountainous slope that is the habitat of Douglas fir, can get congested at times and this can aid in the loss of growth rate. 1980 recorded a small increase in growth, insect infestation, natural disasters and forest fires among others.…

    In this set of materials, the reading passage states the reasons for the decline of the yellow cedar tree and provides three reasons of support. While in listening, the professor opposes the reading passage and says that the reasons are inadequate. He also refutes each of the author’s reasons. First of all, the reading passage claims that the decline of the cedar trees is due to the infestation with the cedar bark beetle, since the larva can eat the tree wood. However, the professor counters this and explains that the beetle can’t infest the healthy tree.…

    Trees naturally sequester atmospheric carbon dioxide through photosynthesis and thus decrease global warming and its repercussions. Carbon dioxide is an essential component of the Calvin Cycle for the production of glucose, which is the primary energy source for plants as well as many herbivorous and carnivorous consumers. With the rapid increase in atmospheric carbon dioxide levels from anthropogenic activity since the Industrial Revolution, scientist suspect that carbon dioxide fertilization will amplify photosynthesis and, therefore, sequester more carbon dioxide from the atmosphere to the terrestrial carbon sink in the form of trees (Bonan 2008).2 Forests are a major terrestrial carbon sink and contain approximately 45% of terrestrial…
