INTRODUCTION.
Quercus alnifolia as termed as ‘The evergreen Golden Oak of Cyprus’ is among the foremost indigenous plants that was described from the Cyprus island ever since 2006 and is also deputed as the country’s main national tree. Even though it is found as large and many-branched shrub, it can also acquire all the looks including the shape and size of a small tree going up to heights of 10m. The species is among three oak species found in Cyprus island and is rare in other places other than troodos mountain range given altitudes ranging from 400-1,800 m. Places where the species is abundant, they form pure or mixed stands with other species such as pinus nigra, pinus brutia, cedrus brevifolia and all other Mediterranean shrubs.
YIELD AND PRODUCTION.
The impact of quercus alnifolia on Cyprus islands ecosystem is large such that its ability to colonize the outside and plunge rocky slopes makes it important for soil stabilization and curbs the problem of erosion in those areas that they cover. On the other hand, it makes broad life-friendly environments in places where other types of trees strive to survive. When it comes to fungi, it is country’s most common broadleaved host, in island areas which are largely dominated by coniferous forests.
Most of the Mediterranean fungi are majorly found associating with Quercus alnifolia of which some have been known to fruit with the Holm oak common all over the Mediterranean and in the other hand absent from Cyprus. Also a large number of Northern European species also fruit in Cyprus more during the latest stages of the season where in mild winters it may extend into January. During the rainy season, especially in august and September, boletes which are rare in Cyprus are usually found under this type of host ranging at an altitude of 1,200-1,800 m. The two typically Mediterranean species are also frequent which include xerocomus dryophilus which is visible at lower temperatures. It is different in its southern distribution and yellow cap flesh above the tube layer and on the other hand Boletus luridus the flesh immediately above the tube layer is clearly red in color. Quercus alnifolia is actually popular host among the Russulales that also appear earlier during the season. Again Russula chloroides, R. delica and R. acrifolia are all extremely common and mostly found under this host but also they fruit under pine. The Russula aurea also fruits early and R. vinosobrunnea closely relate to R. olivacea and R. alutacea is found exclusively under this host and can be found in some years of the Lactarius species, the commonest is Lactarius.
Quercus alnifolia was found to exclusively show allozymes that was also found to be present in Q. ilex and Q. coccifera (quercus) where other Mediterranean oak species could be identified by only either by at least one allele, in other ways, several alleles that is specific to the taxon or by loci and alleles diagnostics of the taxon vis all the others. From a study, the results found can detect some suggestions that the Mediterranean oak species might not have been subjected to substantial interspecies genetic introgression which was the case of other oak species.
SITE INDEX
In site index, there are several methods that are used to determine it. These methods can be based on tree height, plant composition, and also the use of soil maps.
Lets take the example of use of soil maps where for the Quercus alnifolia a ordinal and clu1ster analysis is done. This is to know how well the species will do in different types of soils all across. First landscape scale is identified up the uplands of the Southern Loam Hills within three LTAs. These LTAs had been determined by the USDA forest service.
The LTAs were found to be valid as they showed differences in vegetation, soils, and landform. The symptomatic soil and landform variables p<0.10 level were the B horizon depth, drainage class, A horizon P, percentage B horizon clay and percentage B horizon silt.
After all this, it...
