Nowadays, optimized utilization of forests potentials and seed orchard establishment is not an option rather it is an obligation. In countries such as Iran, which are considered as low forest countries, forest seed orchard establishment is a non-replaceable exigency. This is in such conditions in which unsystematically exploration of forest tree species has caused genetic deterioration and reduction of genetic variation of a great number of valuable forest tree species. Following fulfillment of a national research project on investigation of genetic potential of Haloxylon species, six populations of H. aphyllum collected from Khorasan Razavi, Qom, Yazd, Semnan, Kerman and Sistan and Baluchestan provinces were primarily investigated by which a number of suitable trees with appropriate performance were selected. The selected trees were further investigated by progeny testing in the six provinces. A number of superior genotypes were selected on which H. aphyllum seed orchard was established in Qom, Khorasan Razavi, and Yazd provinces. Using collected seeds on the selected plus trees, seedlings were produced, and a further selection was performed on the seedlings and planted in the seed orchards in such a way that the least relationship could be found between adjacent stands. Optimization of genetic variation in the mentioned seed orchards should be dynamically continued, along with utilization of their outcomes.

Oak decline is a multidimensional and complex phenomenon, involving the interaction of biotic and abiotic factors. The history of this phenomenon goes back more than three centuries ago and the latest has occurred in some European countries during 1980s. Zagros oak forests faced with this phenomenon since 2002s. Nowadays, more than one million hectares of Zagros oak stands is affected by oak decline syndrome. Administrative and technical operations have made clear different aspects of the crisis; however, full control of this crisis requires serious commitment and attention to the importance of it.

Lichens, as ecological indicators, have great value in forests because of the sensitivity to a wide variety of environmental stresses such as air pollution and climate change. So far, many species of lichens have been collected from the Hyrcanian forests to be identified in the lichen herbarium of Research Institute of Forests and Rangelands. Some of these lichens are able to fix nitrogen and are considered as an indicator of air pollution. In recent years, the destruction of Hyrcanian forests has led to a reduction in the diversity and abundance of lichens. Thus, regular studies on the biodiversity of lichens, especially tree lichens and epiphytic lichens are necessary. A number of factors affect the diversity and growth of lichens. Therefore, understanding these factors and timely action may decrease the negative effects on lichens and, as a result, help the health of the Hyrcanian forests.

Among important symbioses, mycorrhizal symbiosis helps the establishment of plant by increasing the rhizosphere distribution, and absorption of water and important soil nutrients such as N, P, and K, leading to increased biodiversity, soil microbial population, and plant resistance against some pathogens and different stresses. This research was aimed to study the influence of symbiosis on morphological characteristics of Celtis caucasica. The study was performed in a natural habitat at Chahartagh, Chaharmahal va Bakhtiari province. The rhizosphere soil and root of five individuals of C. caucasica were sampled. After assessing the symbiosis, arbuscular mycorrihizal fungi were amplified by Zea mayz. Afterwards, the seeds of C. caucasica were inoculated by fungi. Assessments showed that symbiosis was created with 80% colonization. Therfore, the stem height, leaf area and root length in mycorrihizal seedlings were more than 3, 3, and 1.5 times as compared with control seedlings. Therefore, the symbiosis of arbuscular mycorrhizal fungi caused the better growth of mycorrhizal seedlings.

This study was performed to investigate the growth stages of Pimpinella aurea in the field during 2010-2013. This species is one of the valuable medicinal plants native to Iran. b-bisabolene, one of the most important medicinal compounds, is found in inflorescence and seeds of P. aurea. It is used in the pharmaceutical industries and cosmetic and health products due to anti-inflammatory effect. The seeds were collected from a natural habitat in Tehran Province (Touchal). In laboratory, seed purity percentage, moisture content, 1000- seed weight, and germination percentage were calculated. During the study period, it was found that P. aurea was a perennial species, producing seeds after the third year of cultivation. Autumn sowing was better and seed sowing should be done directly in the ground. In addition, it is a monocarpic species and need be subcultured each year.

Algae are the main producer in aquatic ecosystems of ocean and seas which cover 71 percent of the earth planet. These organisms are environmentally very important. Seaweeds also produce a large part of oxygen in the atmosphere. Sothern parts of Iran are bordered with coastlines of Persian Gulf and Oman Sea which have high valuable biological potential that marine seaweeds are one of the most important one among them. During recent years over than 347 species of marine algae have been recognized and reported from this area including 167 Rhodophyta, 79 Chlorophyta, 80 Phaeophyta, 15 Cyanophyta and 6 Diatoms. Some of these seaweeds show high productivity and can be cultivated in commercial scale that will result many job opportunities in Iran.

The genus Quercus, as the most important genus of Fagaceae in Forests of Iran has remarkable diversity in Zagros region. Regarding to ever-increasing degradation of oak forests of Iran, it is essential to evaluate conservation status of native oaks. Based on the IUCN guidelines three criteria were used to evaluate the oak species as follows: extent of occurance, area of occupancy and number of mature individuals. The studied oaks were categorised as follow: Quercus robur subsp. pedunculiflora in critically endangered class, Q. infectoria subsp. boissieri, Q. macranthera, Q. petraea subsp. iberica, Q. castaneifolia subsp. castaneifolia, Q. libani, Q. persica and Q. brantii var. belangeri in vulnerable class, Q. brantii var. brantii in near threatened class. If the degradation trend continues, be protected, it will too.
