| description | Revealing the effect of mixed beech and hornbeam stands on herb layer diversity is essential for sustainable forestry and biodiversity conservation since little is known in Hyrcanian forests. So, we studied the effects of such stands on understory diversity and soil physico-chemical properties in Hyrcanian forests of Iran. Forty sampled plots were established by random systematic sampling method with a regular 100 m × 200 m grid. At each sample point we recorded species identity and percent cover of each tree layer and herb layer species within plots of size 400 m2 (20 m × 20 m) and 100 m2 (10 m ×10 m) respectively. Soil samples were taken from 0 cm -10 cm and 10 cm - 30 cm soil depths. Cluster analysis was used to classify the samples based on the floristic composition data. Also detrended correspondence analysis (DCA) method was employed to assess the relationship between vegetation and environmental variables. There was no significant difference in terms of species richness, and diversity between mixed beech stands and hornbeam stands, but cluster analysis indicated that these stands were separated in two different groups based on herb layer species composition. DCA results showed that litter thickness, soil texture, total nitrogen, and organic carbon in the first layer were considered effective environmental variables in the distribution of sample plots in two stands. We observed that tree layer composition and soil characteristics were crucial contributors to variations of understory species composition which may be changed by forest management approaches over time. Tree layer composition and soil attributes can be considered effective factors for controlling and assessment of understory plant species composition. These findings could provide guidelines for conserving plant species diversity within any framework of sustainable forest management in Hyrcanian forests. |

Determinar el efecto de los rodales mixtos de haya y carpe sobre la diversidad del estrato herbáceo es esencial para la conservación de la biodiversidad y la silvicultura sostenible. De este tema se conoce poco en los bosques Hyrcanian y, por ello, en este trabajo se estudian los efectos de los rodales mixtos de hayas y carpe sobre la diversidad del sotobosque y las propiedades fisicoquímicas del suelo en los bosques Hircanos, en Irán. Se establecieron 40 parcelas mediante un muestreo sistemático aleatorio con una retícula regular de 100 m × 200 m. En cada punto de muestreo, se registró la identidad de las especies y el porcentaje de cobertura de los estratos herbáceo y arbóreo, dentro de parcelas 400 m2 (20 m × 20 m) y 100 m2 (10 m × 10 m). Se tomaron muestras de suelo a profundidades de 0 cm - 10 cm y 10 cm - 30 cm. Se utilizó el análisis de conglomerados para clasificar las muestras con base en los datos de composición florística. También se empleó el método de análisis de correspondencia sin tendencia (DCA) para evaluar la relación entre la vegetación y las variables ambientales. No hubo diferencias significativas en términos de riqueza de especies, uniformidad y diversidad entre los rodales mixtos de hayas y de carpe, pero el análisis de conglomerados indicó que estos rodales estaban separados en dos grupos diferentes, basado en la composición de especies por estrato. Los resultados del DCA mostraron que el espesor de la hojarasca, la textura del suelo, el nitrógeno total y el carbono orgánico en la primera capa se consideraron variables ambientales efectivas en la distribución de las parcelas de muestreo en dos rodales. Se observó que la composición del estrato arbóreo y las características del suelo contribuyeron de manera crucial a las variaciones de la composición de las especies del sotobosque que pueden cambiar con los enfoques de manejo forestal con el tiempo. Por lo tanto, la composición del estrato arbóreo y los atributos del suelo pueden considerarse factores efectivos para controlar y evaluar la composición de las especies de plantas del sotobosque. Además, estos hallazgos podrían proporcionar directrices para la conservación de la diversidad de especies vegetales dentro de cualquier marco de ordenamiento forestal sostenible en los bosques Hircanos.
