The Orto botanico riserva Lago di Penne (Italian: Botanical garden of the Penne Lake Preserve) is a botanical garden located within the Riserva Lago di Penne, southwest of Penne, Abruzzo, Italy. The garden was established in 1988 and contains plants organized by geography and ecological system.
The garden itself covers 1 hectare. It was established in 1988, one year after the Riserva Lago di Penne. In 1997 it was recognized as a botanical garden of regional interest, pursuant to regional law n.35/1997. In 1998, the Reserve adopted a forest management plan using naturalistic silviculture principles.
Visitors enter the garden along the lakeside after passing the visitor center. Continuing along the lake, their path encounters the Duck Center, the Otter Center, and wildlife areas dedicated to ferrets and tortoises.
This is followed by the main botanical walking path (Percorso Botanico). It includes a route dedicated to aromatic plant species, set up for the blind with interpretive signs in Braille, and sections dedicated to Maquis shrubland, downy oak-dominated xeric forest, black hornbeam-dominated mesic forest, riparian forest, and wetland. The garden's plants are arranged by geography and ecology, rather than by taxonomy, in order to reconstruct Abruzzo's major plant associations.
The Orto botanico riserva Lago di Penne is located at 250 m elevation, along the lake shore, with an extension of slightly less than 1 ha along the basin of the river Tavo. The Tavo is a right-hand tributary of the river Saline, on which the Penne dam was built.
Outside specifically cultivated areas, the garden's current wetland vegetation is the result of natural post-dam colonization and succession. Its wild upland vegetation results mostly from reforestation efforts. Before the construction of the dam and the creation of the Riserva and the Orto Botanico, the landscape consisted of farmland with woodlot strips. The area's native climax vegetation is dominated by holm oak.
地質学的に見ると、この庭園は後期中新世から前期鮮新世にかけて形成された堆積盆地の一部に位置し、頁岩と砂岩が交互に堆積している。このような地層は、頁岩由来の粘土と砂岩由来の砂が水に浸かった際の挙動が異なるため、地滑りが発生しやすい。保護区と植物園の目的は、移動しやすい堆積物を固定するのに役立つ植物群落を維持することである。
