Forest Research Division

Forest Research Division has started to undertake research projects since the foundation of Research Institute of Forests and Rangelands (RIFR) in 1968. Taking into account that Iran is a low forest cover country, the primary activities were concentrated on adaptation and elimination trials using 330 different fast growing exotic (needle-leaved and broad-leaved) tree species and provenances in different ecological regions of the country.Forest Research Division has started to undertake research projects since the foundation of Research Institute of Forests and Rangelands (RIFR) in 1968. Taking into account that Iran is a low forest cover country, the primary activities were concentrated on adaptation and elimination trials using 330 different fast growing exotic (needle-leaved and broad-leaved) tree species and provenances in different ecological regions of the country.At the present time, considering the ecological regions, the strategy of our studies is based on ecosystem approach. With new trends in the country and the world, FRD is dealing with sustainable forest management, close to nature silviculture, rehabilitation of degraded forests areas by using different reforestation methods as well as afforestation methods in non-forested areas, in order to decrease the pressure on natural forests and producing wood out of forest areas.
Subdivisions:1- Forest Ecology and Forest Science ۲- Forest Management and Biometry Research Group3- Forest Plantation and Tree Breeding Research Group4- Forest Soil Research Group ۵- Socio-Economic Issues and Forest Utilization Research Division
Also in the international framework of forest research division, a group called “Beech Research Group” is established and has cooperation with IUFRO.
◊ Forest Ecology and Silviculture Research GroupThe main strategy of this research group is based on close to nature Silviculture and treatment of forest trees and stands, taking into account their natural structure and requirements.Duties:
*Investigations on the influence of ecological factors on presence and growth of forest tree species;*Study on unique forest ecosystems;*Application of silvicultural systems and tending operations in natural and man made forests.
   Some of undergoing and completed projects within this group are:*Site demands of forest tree species on different ecological regions;*Role of ecological factors (light, temperature, moisture etc.) on establishment and growth of seedlings and tree species;*Study of seeding cycle in different tree species;*Investigation on qualitative and quantitative characteristics of natural regeneration under different condition;*Structure of natural forest stands;*Application of even-aged and uneven-aged methods in different forest stands;*Impact of silvicultural operations (thinning, lightening) on the quantitative and qualitative characteristics of natural and man-made stands (e.g. on beech, maple, pine and spruce plantations);

*Study of development stages on natural undisturbed forest stands*Impact of silvicultural operations in coppice stands (western oak);*Influence of environmental and genetic factors on the quantitative and qualitative characteristics of oriental beech;*Studies on long-lived trees in different parts of Iran;*Study the ecosystem of Mangrove forests in South Iran.
Achievements:Among activities of this group several reports, 3 books and more than 30 articles in different scientific journals have been published which includes forest and poplar research periodical, journal of natural resources of Iran and research and Sazandegi magazine.

 *Establishments of seed orchards,*Evaluation, conservation and advancement of genetic variability on forest trees by in situ and ex situ conservation methods.
*Investigation on adaptability of various species (almost 300 species and provenances) at different ecological regions.*National project of the pioneer afforestation in south of Iran.*Establishment of seed orchard (Ash and Lime in northern Iran).*Plantation trials with multi-purposes tree species.*Impact of afforestation on restoration of damaged forest ecosystems by Kuwait burning oil wells.*Application of swage in forest plantation.
*Impact of different light and hormonal treatments on sexual and asexual regeneration of juniper.
*Genetic diversity and differentiation of oriental beech (Fagus orientalis Lipsky) populations as the basis for development of silvicultural and gene conservation strategy in Iran.
*Gene flow among Oriental beech (Fagus orientalis Lipsky) populations.
