Trump made a big mistake in assassinating Sardar Qassim Suleimani. Because martyr Qassim was a myth for Iran. The assassination of a myth and This national hero, namely, the assassination of a nation. Trump, even after the presidency, must seek a mouse hole to hide in order to escape the eternal wrath of the Iranian people.
ترامپ اشتباه بزرگی را در رابطه با ترور سردار قاسم سلیمانی مرتکب شد. چون شهید قاسم برای ایران یک اسطوره بود. ترور یک اسطوره و این قهرمان ملی، یعنی ترور یک ملت. ترامپ، حتی بعد از ریاست جمهوری، باید دنبال سوراخ موش برای پنهان شدن باشد تا از خشم ابدی ملت ایران در امان باشد.

Buxus from buxacess the most important species of buxus include: B.sempervirens, B.chinensis and B.hyrcana.
Caspian box is evergreen that distributed tree and shrub in the Caspian coast and the northern Forests or Iran as one of the endemic species
Is considered .global distribution of Caspian box is reported Turkmenistan too.
Box has high longevity, it quietly was shade tolerant. And it stands have the best quality or growth into understory of forest. Box trees generally were seen until 12 meters height and up %0.35 meters in diameter. The north Forest in Iran is component of deciduous broad leaved forests by warm temperate weather or summer – green regime. But parts of plains and mountainous the boxes presented we can know under of rainforest and summer- green.
The traditional harvests of boxwood
Before nationalization of forests, specially during the qajar and the first pahlavi occurred very hard harvest from box trees by foreign- contractors, above all by the Greek. In the past, people made woody spool combs, textile lathe and other tools.
Box as medicinal species were considered more common in the forest and today, it rarely is using.
a lot of Caspian box habitat land used and changed for rural, villages and cities development that used tea gardens rice farms and other crops, making house and yard,so that Caspian box habitat decreased and limited.
Stimation of the box stands and trees
According review plan of quantitative and qualitative studies Iran forests (2006 or 1385), Bucus hyrcana has %0.39 in number and %0.4 in volume of forest trees.
Box's area is reported about 12000 hectares in guilan province.
But this habitats estimated about 15000 until 20000 hectares.
History of diseases in the north forest of IRAN.
In the past decades. The incidence of pests and diseases destructed habitats of some of forest species include:Castanea sativa(chestnut), Ulmus glabra(mountain elm), Albizia julibrissin(silk tree).
Boxwood blight disease has occurred (in 2010) in recent years, and despite the short duration or pathogen attack, irreparable damage have entered into box masses.
The necessity of controlling boxwood blight
Box stands or forests within boxus hyrcana are sustaining fauna and flora of forest ecosystem, so that with distribution of its habitate disrupted the balance of ecosystems and various damages will be noticed human society.
Imagine destruction of the nests of insects or and birds and other creatures following blight disease is terrible and unexpected event.
That is damages are much more than a flood or earthquake.
Certainly with destruction of box habitats increase possession of national grounds and attendance of domestic animals in the forest.
Therefore necessary to deal that we do measures to effectively implement for prevention and control of boxwood blight.
