Iran is recognized as a land of high biodiversity in Southwest Asia. The northern slopes of the Alborz Mountains host a wide variety of ecosystems and microclimates, with the Hyrcanian forests forming one of the most significant vegetation covers in this region. Parrotia persica C.A. Meyer, a semi-endemic and relict species in the Hyrcanian forests of northern Iran, is absent from the forests of Arasbaran and Europe. The distribution of ironwood (Parrotia persica) typically ranges from lowland areas up to 1200 meters above sea level (m.a.s.l.) and occasionally up to 1400 m.a.s.l. However, in the Kojur region (Poul city) of Mazandaran Province, a pure stand of old ironwood trees has been recorded at altitudes between 1600–1650 m.a.s.l., known as the Sad Injili Reserve. This site represents the highest known altitudinal range for Parrotia in the Hyrcanian forests, underscoring the urgent need for its conservation. Despite its ecological uniqueness, this habitat has not been granted effective protection and remains under severe pressure from livestock grazing, tourism impacts, and habitat degradation. The present study highlights the importance of conserving this rare ecological site, which marks the upper limit of Parrotia’s ecological niche in the Hyrcanian region. It is hoped that the Forestry Office, as well as national parks and forest reserves, will take immediate and effective action to ensure the protection and preservation of this valuable natural heritage.
