Habitat degradation is one the important reasons of plant species extinction. Modeling techniques are widely used for identifying the potential habitats of different plant species. Thus, the purpose of current study was to determine potential habitats of Zalzalak in Lorestan Province. Species presence data and 23 environmental variables were collected in Lorestan Province. Correlation analysis was then applied to reduce the environmental variables into nine effective ones and potential habitat of the species was determined using five models including Maximum Entropy (MAXENT),Generalized Linear Models (GLM), Generalized Additive Models (GAM), Multivariate Adaptive Regression Splines (MARS) and Generalized Boosting Model (GBM). Models were evaluated with receiver operating characteristic (ROC) plots, true skill statistic (TSS) and Kappa coefficients. Results showed that ROC and Kappa coefficients were excellent for all models and TSS values were excellent for GBM and MAXENT, good for MARS and GAM and medium for GLM model. According to the combined model, 40% of the province was classified as suitable and 60% as unsuitable. The precipitation of the three coldest months of the year, annual rainfall and elevation were the most effective environmental variables in Zalzalak habitat mapping. The maximum presence of the species occurred at the rainfall and elevation range of 160–220 mm and 1300–1850 m, respectively. Due to the high accuracy of the Zalzalak suitable habitat map, it can be used by related organizations, as an appropriate tool for reclamation of degraded regions and conservation of current habitats.

In recent decades, tragacanth gum extraction from Astragalus verus has dramatically increased across Iranian rangelands. However, little information is available about the best method of gum harvest, which is economically efficient and maintains the health of the plant. This research was conducted as a factorial combination and in a completely randomized design, during spring and summer of 2018-2019, at Baraghban rangeland. Three levels of stem cuts (i.e. 1, 2, and 3 cuts on the main stem of each plant) and four frequencies of gum removals (1 to 4 times) with 10 replications were applied on 120 individual plants. Results indicated that all cut and gum removal levels significantly reduced the vigor of A. verus, but no significant relationship was detected between gum removal levels and plant vigor. There was an increase in the gum yield by increasing the number of gum harvests, but no increase was found by increasing cut numbers. Based on the ecological and economic comparisons (estimating costs and benefits), we suggest one cut and four times of gum removal as the most suitable method.

Habitat and ecosystem fragmentation and, consequently, the loss of landscape connectivity are major causes of biodiversity destruction, leading to disruption of material, energy, and information flow at the landscape scale. Given the importance of this issue, the current study aimed to evaluate the ecological connectivity and spatial planning of Qazvin Province, in order to re-establish and protect material, energy, and information flow corridors, using a landscape ecology approach. With that in mind, land use/land cover map was used to identify ecologically functional areas and to map barrier effect and ecological connectivity indicies by mathematical modeling techniques using model builder algorithms in Geographic Information System (GIS). Appropriate patches were, then, spatially selected for restoration and conservation across the landscape. The results showed that 90% of the province has the ecological function, but 10% of the area lacks the function. Three percent of the area has lost its ecological function by physical barriers such as road networks and industrial and residential expantions, and 7% of the area lost its functionality due to anthropogenic effects. In this research, four corridors were identified for spatial planning. Results of this study can be used for management of protected areas and land use planning, as well as environmental impact assessment and envuronmental strategic assessment.
