Grassland communities dominated by perennial bunchgrasses and annual herbs cover significant portions of the park, particularly on slopes and plateaus. Shrubland ecosystems include various Astragalus species, Artemisia (wormwood), and other aromatic shrubs common in Iranian mountain steppes. Trees are likely limited to scattered individuals or small groves in favorable microhabitats with better water availability, potentially including wild almond, wild pistachio, and juniper species. Riparian vegetation along any seasonal streams would include willows and other water-dependent plants. The park's flora shows seasonal patterns, with spring bringing abundant wildflower displays before summer dormancy. Endemic and rare plant species may occur given the diverse topography and ecological gradients within the park. Vegetation provides critical habitat structure for wildlife and helps prevent erosion on mountain slopes. Conservation of plant communities in Sirkheh supports ecosystem processes and maintains genetic resources valuable for understanding adaptation to semi-arid environments.

Sirkheh National Park's geology is shaped by its location in Tehran Province's mountainous terrain, part of the broader Alborz mountain range system. The park encompasses rocks and landforms characteristic of this tectonically active region, including folded and faulted sedimentary rocks, possible volcanic intrusions, and metamorphic formations. Elevation gradients within the park create diverse topographic features from higher mountain ridges to lower foothill slopes and valleys. Sedimentary sequences may include limestone, sandstone, and shale deposited during various geological periods. Erosion has sculpted the landscape into hills, canyons, and badlands features typical of semi-arid mountain environments. Seasonal streams have carved channels through the bedrock, creating drainage networks that concentrate water during wet periods. The underlying geology influences soil development, water availability, and vegetation patterns across the park. Tectonic activity associated with the Alborz Mountains may be evidenced by faults, tilted rock layers, and seismic potential in the region. Geological diversity contributes to habitat heterogeneity and supports the park's ecological values. Understanding the geology is important for managing erosion, planning infrastructure, and interpreting the park's natural history for visitors.

Sirkheh National Park experiences a semi-arid continental climate characteristic of Tehran Province's foothill and mountain regions. Precipitation is limited, with most rainfall occurring during winter and early spring months, while summers are hot and dry. Annual precipitation totals are insufficient to support dense forests, resulting in the grassland and shrubland ecosystems that characterize the park. Temperature extremes are significant, with hot summer days potentially exceeding 35-40°C and cold winters where temperatures drop below freezing, particularly at higher elevations. Snowfall occurs during winter months, providing moisture that supports spring vegetation growth. The diurnal temperature range is large due to the semi-arid climate and elevation, with significant cooling at night even during summer. Wind can be a factor, particularly during seasonal transitions. The park's climate influences the phenology of plants and wildlife activity patterns, with many species showing adaptations to avoid the hottest and driest periods. Climate variability affects water availability in seasonal streams and springs, which are critical resources during dry seasons. The proximity to Tehran creates potential urban heat island effects on park margins. Climate change may alter precipitation patterns and temperature regimes, affecting the park's ecosystems and requiring adaptive management strategies.

The human history of the area now encompassed by Sirkheh National Park reflects Tehran Province's long settlement history and changing land use patterns. Archaeological evidence from Tehran Province indicates human presence extending back thousands of years, with populations exploiting mountain resources for hunting, grazing, and resource extraction. Traditional land uses would have included seasonal grazing by nomadic pastoralists who moved livestock between lowland and mountain pastures. Local communities may have harvested wild plants for food, medicine, and craft materials. As Tehran grew into a major city, pressure on surrounding lands increased, with expanding agriculture, settlements, and resource exploitation affecting natural ecosystems. The decision to establish Sirkheh as a national park represents recognition that uncontrolled development would eliminate important natural areas near the capital. Historical land management practices, both sustainable and degrading, have shaped the current condition of the park's ecosystems. Cultural connections to the landscape may persist among communities with historical ties to the area. The park's creation likely involved transitions from traditional uses to conservation-focused management, requiring negotiation with stakeholders. Understanding this history informs current management and helps build support for conservation among people with connections to the land.

Sirkheh National Park was established as part of Iran's protected area system to conserve natural ecosystems in Tehran Province. The specific date of designation and the circumstances leading to park creation reflect broader conservation efforts in Iran during the late 20th century.
