1: Pollution Effects of the Persian Gulf War on the Southern Regions of Iran (granted by UNCC as an international project, project number 5000427, in 2004)

This research was carried out in ten provinces. Our findings demonstrate that tress could be used as important bio-indicators. Totally values of forest damaged in the Zagros and Khaliji-Omani region of Iran calculated.


2: Reasons of longevity in Iranian long-lived cypresses ( This project has been funded by Iran national science foundation, in 2007)

In this project after estimating biological age of each tree, the factor which causes longevity will be studied. In other words longevity factors will be determined and introduced by use of ecological, ecophsiological and genetical studies. The results of this study not only can be registered as valuable cultural heritage of Iran in UNESCO but also can be used in rehabilitation of damaged forests. In addition the identified seed exchange will be done as an important economical value in international scale.


3: Study of 25 year Variation in Air Pollution Uptake and the Tree Response (Case study, Platanus Orientalis, in 2008)

In This study, 60 individuals of Plane Species were selected. Using the pollution map of Tehran, we were able to select sampling tree from the most to least polluted areas. The results indicate that plane tree growth have dramatically decreased during the past 10 year.


4: A survey plan for inspecting plane and mulberry trees conditions in Tehran and determining the pollution resistant individuals, 2009

Platanus orientalis together with Morus alba have been planted in most regions in Tehran years ago. In this research, 15 trees of each species in 16 studying sites sampled. It was tried to select trees of the same phenotypic and to some extant of the same ecologic conditions. The results show the maximum chlorophyll activities in two sites of Yakhchal and Abolabad and the minimum in Narmak, Terminal e Jonoob and Baharestan in case of plane. When it came to mulberry, Azadi square showed the maximum activity and Yakhchal the minimum The results suggest chlorophyll content (as the fuctional unit of photosynthesis) increased by risen air pollution likely due to avoid of photoinhibition.


5: Rehabilitation management based on community participation and recognition of stable (elite) oak stands in Ilam province


This project is granted by SGP (Small Grant Projects of Global Environment Facilities) and co- financed by Forests and rangelands organization of Ilam and the Technology of Natural Sustainable Ecosystems Research Groups.

Ilam province was selected as the case study due to its higher damaged area. It is hypothesized that the mortality of oak stands are caused by degradation of natural ecosystems of Zagros forests including Ilam province.During the last years, the climate change consequences, for instance the lack of precipitation and the intensifying haze contaminated with toxic materials are among of the most important mentioned environmental stresses.

In the first place, the degradation severity of the natural system will be proved through this project. The oak species have been shown the higher sensitivity rather than other species because of phenotypic specifications such as leaf blade.Even though the reasons are quite diverse even in similar species. Ecological shelters, fundamental and genetic resistance of some of the oak stands to the environmental stresses including contaminants can be some of the possible causes of this issue.

Additionally, accomplishment of this project is based on trust-building and participation of communities in order to involving them in recognition of the problem, implementation and acceptance of the impact of the main goals of the current project on the quality of their life in future.

Generally, this project is looking for rehabilitation management of Zagros oak forests based on community participation to achieve its two major targets.

The first target is introduction of scientific and functional model to rehabilitat Zagros oak forests. It will lead to the following outputs:

Output No.1: Determination of the mortality causes (internal and external) of oak forests  through available information and achieved results;

Output No.2: Identifying the elite stands, rehabilitation of the forests utilising 60% of the elite stands with regard to species and intraspecies diversity.

The second goal is to remedy the life style of local people concerning the forest ecosystem potential of the area thanks to community participation in rehabilitation of forest ecosystem. It will result in the following outputs:

Firstly, empowerment of the local people through threatening them about mortality reasons of forests and its catastrophic consequences;

Secondly, indentification of alternative life style regarding available ecosystem potential like ecotourism and by-products of forests and rangelands.

Thirdly, identification of the main and subsidiary sources of revenue of the local and its enhancement through remedy production and selling methods.
