ABSTRACT Morialta Conservation Park is a scenic protected area that contains important vegetation remnants of the Mount Lofty Ranges. Here we investigate the vegetation ecology, soils and plant diversity of the park. Using a stratified, quantitative survey of woody vegetation and topsoils throughout the park within forty-five 10 × 10 m plots, we identified ten distinct vegetation types, nine being native and the other being dominated by the invasive European olive (Olea europaea). Soil conductivity and fertility, as well as aspect, were significant predictors of species composition, indicating that high environmental heterogeneity in soils and topography are important in facilitating the high biodiversity in the Morialta Conservation Park. The European olive and Boneseed (Chrysanthemoides monilifera ssp. monilifera) are widespread in the park and a threat to native vegetation. Using published plant lists and the Atlas of Living Australia, we report 486 native (and 300 introduced) plant taxa from the park and its immediate surrounds, including species considered endangered at either the state or national level, or the IUCN Red List. Therefore, the park is highly important for conservation and the threat posed by the European olive, Boneseed and other invasive species should be effectively managed.

Morialta 保护公园中本地植物和植被类型的高度多样性以及入侵物种的威胁

摘要 Morialta 保护公园是一个风景优美的保护区，包含洛夫蒂山脉的重要植被遗迹。在这里，我们调查了公园的植被生态、土壤和植物多样性。通过对整个公园内 45 个 10 × 10 m 地块内的木本植被和表土进行分层、定量调查，我们确定了 10 种不同的植被类型，其中 9 种是原生的，另一种主要是入侵的欧洲橄榄（Olea europaea）。土壤电导率和肥力以及方面是物种组成的重要预测因子，表明土壤和地形的高度环境异质性对于促进 Morialta 保护公园的高度生物多样性很重要。欧洲橄榄和去骨（Chrysanthemoides monilifera ssp. monilifera）在公园内广泛分布，对原生植被构成威胁。使用已公布的植物名录和澳大利亚生活地图集，我们报告了来自公园及其周边地区的 486 种本地（和 300 种引入）植物分类群，包括在州或国家级被认为濒危的物种，或 IUCN 红色名录。因此，该公园对保护非常重要，应有效管理欧洲橄榄、带骨和其他入侵物种构成的威胁。
