“…Also, using native species in plantations could decrease the concern of adaptation and being infected the pests and diseases. The study on plantation in Iran and the other part of the world was extended in recent decades (Abdy and Mayhead 1992;Allen et al 1995;Menalled et al 1998;Ferris et al 2000;Coroi et al 2004;Lindenmayer and Hobbs 2004;Yamashita et al 2004;Lee et al 2005;Lemenih and Teketay 2005;Pourbabaei et al 2005;Corney et al 2006;Ginsberg 2006;Mosayeb Neghad et al 2007;Pourbabaei and Roostami Shahraji 2007;Poorbabaei and Poorrahmati 2009).…”

Pourbabaei H, Asgari F, Reif A, Abedi R. 2012. Effect of plantations on plant species diversity in the Darabkola, Mazandaran Province,. In this study, the effect of plantations on plant species diversity was investigated in Darabkola, Mazandaran province, north of Iran. To conduct the study, a natural mixed forest, a broad-leaved plantation (Alnus subcordata-Acer velutinum) and a coniferous plantation (Cupressus sempervirens var. horizontalis-Pinus brutia) were selected. 35 sampling plots were taken in systematic random method in each area. Data analysis was carried out using Simpson, Hill's N 2 , Shannon-Wiener and Mc Arthur's N 1 diversity indices, Smith and Wilson evenness index and species richness. Results revealed that there were 32 plant species in natural forest and 30 plant species were found in each plantation. Rosaceae and Lamiaceae were the main families in the studied areas. Diversity and evenness indices of all vegetation layers had the most values in the natural forest. Richness of woody plants had the highest value in the natural forest, while herbaceous richness was the highest in coniferous plantation. Mc Arthur's N1 had the highest value among diversity indices and followed by Hill's N 2 , Shannon-Wiener and Simpson indices, respectively. In addition, results showed that there were significant differences among diversity, evenness and richness indices in all vegetation layers in the three studied areas.

“…There tend to be few types of species per plot, comprising a small percent of the cover as compared with the dominant F. sylvatica (Coroi et al, 2004). Although we might expect natural forests to be more diverse than plantations (Coroi et al, 2004;Wulf, 2002), in this study, the pine plantations tended to be more diverse than the natural forests. The P. radiata plantations had greater mean richness and higher diversity values than the mixed oak and beech forests.…”

Abstract• In forests, the substitution of broadleaf species by conifers can reduce biodiversity because coniferous forests generally provide less diverse vascular understories than broadleaf forests. However, in some cases, former pine plantations might be useful for restoring native forests. We compared plant species composition on the plot scale in natural beech and mixed oak forests with that in plantations of Pinus radiata. Links between plant diversity and landscape parameters (patch size, fractal dimension and distance to the nearest patch of the same type) were investigated.• The objective of this study was to evaluate the use of pine plantations for restoring native diversity in a zone where native forests are very fragmented.• Similar to oak forests, plant diversity in pine plantations was high, mainly due to the presence of generalist species. Some species characteristic of oak forests also appeared in pine plantations, suggesting the onset of natural forest regeneration.• These results suggest that pine plantations could be used to promote natural regeneration of original oak forests. Moreover, residual native stands should be conserved as important sources of native species and their seeds.

Toutefois, dans certains cas, les anciennes plantations de pins pourraient être utiles pour la restauration des forêts naturelles. Nous avons comparé la composition des espèces végétales à l'échelle de la parcelle en hêtraie naturelle et chênaie mixte de même que dans les plantations de Pinus radiata. Les liens entre diversité végétale et paramètres du paysage (taille des bouquets, dimension fractale, et distance du plus proche bouquet de même type) ont été étudiés.• L'objectif de cette étude était d'évaluer le recours à des plantations de pin pour le rétablissement de la diversité naturelle dans une zone où les forêts sont très fragmentées.• La diversité végétale des pinèdes, similaire à celle des chênaies, était élevée, principalement en raison de la présence d'espèces généralistes. Certaines espèces caractéristiques des chênaies sont aussi apparues dans les plantations de pins, ce qui suggère l'apparition d'une régénération de la forêt naturelle.• Ces résultats suggèrent que les plantations de pins pourraient être utilisées pour promouvoir la régénération naturelle des chênaies originelles. En outre, les peuplements résiduels originels devraient être conservés comme sources importantes d'espèces naturelles et de leurs graines.

“…Conversely, moisture from Caspian Sea has caused Hyrcanian (Caspian) forests to flourish into the oldest and richest Eurasian temperate forests in north of Iran for so long (Marvie Mohadjer, 2006). Plant communities usually are diverse and distribute along gradients in the mountains and plains because of spatial variations (Jackson and Caldwell, 1993;Fu et al, 2004;Kialashaki & Shabani, 2011) and climate regime (Grytnes & Vetaas, 2002;Coroi et al, 2004).…”

Iranian natural ecosystems have aesthetic, conservation and genetics values and provide many functions and services, but have become vulnerable. This investigation aimed to (1) survey flora of an arid-steppe montain ecosystem, (2) analyze the ecological characteristics of the vegetation in relation to altitude and soil properties and (3) elaborate on ecophysiological processes. Samples of soil and plants were collected randomly in three altitudes at about 36° latitude in Parvar Protected Area (PPA), Iran. Plant species were identified, ecologic and floristic data were collected and statistical analyses were performed using Excel and SPSS. Physiognomy of the region is steppe. The type of soil is sandy-loam, and it becomes loamy with increasing altitude. Majority (45.5%) of species are cryptophytes and belong to Irano-Turani region followed by chameophytes (36.4%) and therophyte (18.1%). Artemisia aucheri, Eremopyrum elengutum and Stachys aucheri dominated at the upper (2338 m), middle (2009m) and lower (1783 m) elevations above sea level, respectively. Onobrychis cornuta and Astragalus ochrochlorous were also common to all stations. Ecological indices showed reducing trend with hike in altitude except dominance index which increased. Artemisia aucheri was the overall dominant plant and in need of ecological management. Ecophysiological interaction of plant species with environmental parameters at local level undoubtedly determines their community structure, scale and pattern of distribution. Since plant species in semi-arid regions have developed specific adaptation strategies to cope with environmental changes, it is useful to link local adaptation strategies (for example, avoidance, tolerance, resistance) and physiological processes to global changes. In this way, knowledge on morphology, physiology, life-history, phenology and behavior gained from ecological studies based on individuals, communities and ecosystems can be analyzed in ecological and evolutionary context and thus, afford the tool of predicting responses and simulating ecosystem models to environmental changes in future.
