Silvicultural features and environmental values

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.


Analysis of Current Condition

Factor of boxwood blight Spread in most typical habitats in mountainous and plain areas and it happened in a short period of 3 years from 2010 to 2012.

Implementation strategies proposing in guideline of medical plant committee are faced with severe shortage of fund.

 on the other hand defined types for larges habitats with due to the irregular distribution need funds, facilities and labor – intensive and relatively it will be long.

Fungus blight damages are seen the most forest stands in low Part elevations but in the upper elevations (for example in 1600-1700 meter at the shanderman watershed).

There are Box ecotypes intolerant to cold by less moisture.

That resistant to blight disease.

For deliverance of Box habitat, we should be used the proliferation and propagation From resistant ecotypes or healthy basis then boxwood forests will be restored.

In any case, we ought to avoid boxwood destruction are essential rehabilitation and conservation activities,


According to the guidelines developed by Forests organization.

We should collect the whole parts of polluted Stands implementation forest heath

We hope, with having a share FAO's aids or each other Finance.

We start rehabilitation and Conservation activities in the box habitats.
