Global Warming in evergreen Forest short answer
Answers
Answer:
Climate change could alter the frequency and intensity of forest disturbances such as insect outbreaks, invasive species, wildfires, and storms. These disturbances can reduce forest productivity and change the distribution of tree species. ... In other cases, existing species may shift their range or die out.
Answer:
Temperate evergreen forests
Temperate evergreen forests are found in the United States, Canada, Europe, and Asia, in areas that generally receive between 300 and 900 mm of rain per year and with seasonal temperature extremes ranging from -40 to 20 °C. Climate differences occur between the northern and southern evergreen forests, where in northern areas, winters are commonly long, cold, and snow dominated, relative to the more southern coniferous forests, where precipitation and temperatures are more evenly distributed throughout the year (Ichoku, 2018). Vegetation includes coniferous-evergreen tree species that produce cones and needles, dominated by spruce (Picea), pine (Pinus), fir (Abies), and hemlock (Tsuga) species, and the trees retain at least some of their needles year-round. In the southern hemisphere, conifer genera also include Araucaria and Podocarpus, which are widespread and common.
The evergreen forests of the Mediterranean do not seem to need further efforts in terms of the establishment of protected areas, as shown by the assessments conducted in various protectionist areas (see Red List and Article 17 of the Habitats Directive).
Tropical evergreen forests (generally called rainforests) comprise the largest single forest biome in the world (see Table 2.1). They lie (by definition) within the tropics, in areas where air temperatures are relatively high, with little seasonal or diurnal fluctuation (20-30 °C), rainfall is generally greater than about 1500 mm per year, and relative humidity is uniformly high. As in all the forest types we consider, there is a broad range of subtypes within tropical forests, ranging from lowland to montane types. The large differences in climate and parent material have a pronounced impact on the structure and function of tropical forests (Vitousek and Sanford, 1986), and it is dangerous to make generalizations about such a large forest biome.
