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.

莫里亚塔自然保护公园是风景秀丽的保护区，其中包括芒特洛夫特山脉的重要植被残留物。在这里，我们研究了公园的植被生态，土壤和植物多样性。通过对整个公园内45处10×10 m地块内的木质植被和表层土壤进行分层，定量调查，我们确定了十种不同的植被类型，其中九种为原生植被，另一种为入侵性欧洲橄榄（Olea europaea）。土壤的电导率和肥力以及纵横比是物种组成的重要预测指标，表明土壤和地形的高环境异质性对于促进Morialta保护公园的高生物多样性很重要。欧洲橄榄和博内塞德（Chrysanthemoides moniliferassp。monilifera）在公园中分布广泛，并威胁到本地植被。使用已发布的植物名录和《澳大利亚生活地图集》，我们报告了公园及其附近地区的486种原生植物（和引入的300种）植物分类群，包括在州或国家级或IUCN红色名录中被视为濒危物种。因此，该公园对于保护非常重要，应有效管理欧洲橄榄，博内塞斯（Bonesed）等入侵物种构成的威胁。
