The country's need to the cellulosic resources is constantly increasing, and currently according to a very small area of northern forests and restrictions on timber harvesting, meeting the needs through domestic resources is not possible. Therefore, wood imports are inevitable to protect the country's forests as well as meeting the domestic requirements. On the other hand, importation is always subjected to great risk of quarantine pests and diseases. These destructive agents with infected woods are transferred from one country to another and, in the event of the establishment, can cause heavy damage to the forests in the country of destination. Currently, more than half of the country's need to wood is supplied from Russia. Despite health certificate, the timber cargoes have lots of quarantine pests and pathogens. With the continuing entry of this group of pests and diseases, the possibility of their establishment in northern forests is not unexpected. Therefore, study and introduction of these harmful agents, control methods, and also risk assessment of their establishment can play an important role in providing proper solutions for the low risk importation of wood.

per
Current data for the Iranian desert area are derived from the statistics published by the Forests, Rangelands, and Watershed Organization. It should be noted that these statistics have no scientific basis since what has been presented about the area of deserts is merely related to the desert phenomena and facies, discussed in geomorphology. While, the formation of the Iranian natural deserts is under the interaction effects of environmental factors including climate, soil, plants, geology, geomorphology, and hydrology, either directly or indirectly involved in the development of desert conditions. Therefore, separation and determination of the Iranian desert area should be performed with considering all the above-mentioned criteria. The Desert Research Division, RIFR, has determined the territory of the Iranian deserts in a research project with considering all the factors enumerated above and with collaboration of over 65 scholars and experts. According to the obtained results, the total area of the Iranian deserts was calculated to be 907293 square kilometers, covering 55 percent of the whole area of the country.

Cultivation and establishment of perennial medicinal plants in the low-yield dryland farms and degraded rangelands can prevent the erosion caused by annual repeated plowing, and create changes in the conservation and restoration of dryland agricultural ecosystems. To prove this hypothesis, several experiments were conducted in the form of a national plan in seven key dryland areas in North Khorasan, Guilan, East Azarbaijan, Kurdistan, Kermanshah, Isfahan, and Tehran during 2007-2011. Field experiments were carried out in a split-plot design, containing species as main plot at 10 levels (10 Thymus species) in different areas, and density as subplot at three levels (4, 6 and 8 plants per square meter). The results of field experiments in different years and different provinces revealed the establishment of all species studied under rainfed conditions. The highest dry matter yield in Thymus daenensis (2994 kg ha-1) and T. kotschyanus (2884 kg ha-1) was recorded for Kurdistan, Kermanshah, and Tehran at a density of eight plants per square meter. The oil yield varied from 0.69-3.11% in different treatments. The highest oil percentage was obtained for T. daenensis in Kermanshah and Kurdistan. According to the results, the increased dry matter yield at high density under rainfed conditions of Kermanshah, Kurdistan, and Tehran indicates the high production capacity of thyme under rainfed conditions with an annual rainfall up to 400 mm and in cold semi-steppe regions. The highest amount of thymol (80.33%) and carvacrol (71.9%) was recorded for T. daenensis and T. kotschyanus in Damavand. Results indicate the appropriate establishment and yield of local thyme species under rainfed conditions that could be introduced as perennial medicinal plants for dryland farming.

The genus Astragalus with 844 species is one of the huge genera in Iran, containing about 620 endemic species. The genus covering about 15-17 million ha, plays an important role in ecosystem equilibrium, soil conservation, carbon sequestration, and forage production of some species.

Moringa: A hidden treasure in the heart of stone

Moringa is one of the semi-tropical vegetation elements, distributed in the Sahara Sindian region, near the Dead Sea, Red Sea, Somalia, Saudi Arabia, Oman, UAE, Iran, and Pakistan. Moringa distribution in Iran is limited to the mountainous areas of Hormozgan and Baluchestan in Iran. Moringa is a chasmophyte species, growing well on fractured sandstone, shale, and schist. It grows in a warm and dry climate with no frozen period, a mean annual rainfall of 180-200 mm, a mean annual temperature of 26-27ºC, and a mean annual evapotranspiration of 3448 mm. The soil of habitat varies from shallow to very deep with different soil textures, a pH of 7.85 to 8.3, an electric conductivity of 1.36 to 4.5 ds/m, and no salinity limitation. This tree plays a key role in the local economy due to the various values including conservation, wildlife habitat, feed and fuel, beekeeping, nuts, edible oil, and medicinal and industrial uses. The seeds containing 53.9% oil, are traded at a price of $100/kg in the global market. The species is highly resistant to drought stress and able to adapt and expand in the Sahara Sindian region with minimal water requirements. Direct seeding and seedling methods using water storage systems like contour trenching, crop residues, and polyethylene sheets could be used for Moringa habitat restoration in the southeastern Iran.

Due to the ecological diversity in Kurdistan province, there are ecosystems, which are of greatest importance in terms of species diversity and rare plants. These ecosystems are present across the province, especially in the west. The Zarivar Lake is one of the most important habitats in the city of Marivan. This site is of great importance in terms of tourist attractions. As an ecological unit and an aquatic ecosystem, the Zarivar Lake is considered a very beautiful and rare phenomenon in Kurdistan, located in a relatively wide longitudinal valley and surrounded from the west and east by the mountains covered with forests. The dominant vegetation cover of the region is semi-dense forests, whose dominant species is oak, forming the tree and shrub elements together with Pyrus syriaca, Crataegus meyri, and Amygdalus lycioides. A dense vegetation cover of herbaceous plants covers wide areas of the lake. So far, 271 species, belonging to 53 families and 183 genera, have been identified and introduced around the lake. Some of the species, like Tetrataenium nephrophyllum, are endemic to the Zarivar Lake, and the others, like Carex pseudocyperus, are reported for the first time from the west of Iran. The presence of endemic and rare plant species in the Zarivar Lake doubles the importance of vegetation and conservation of these valuable plant genetic resources. The Zarivar Lake is also rich in fauna including mammals, birds, reptiles, amphibians, and numerous microscopic organisms are living in this habitat.

The conservation status of medicinal plants endemic species of the genus Satureja were evaluated and defined based on IUCN threat categories. Stureja avromanica, S. edmondi, S. kallarica, S. khuzestanica, S. kermanshahensis and S. rechingeri were evaluated in different field studies according to three categories: area of occupancy, extent of occurrence and the number of mature species in populations. All evaluated species were defined as "Critically Endangered" (CE). In addition scientific and practical solutions to restore these species are suggested.
