Indigenous societies’ interactions with plants may result in contemporary distribution patterns that reflect these relationships, such as concentration of resource species close to occupation sites or transport routes. Seeds of the cycad, Macrozamia dyeri, are food of Nyungar First People of the south‐eastern Southwest Australian Floristic Region. Processing of seeds by leaching in soil or water enables detoxification and preservation of the pre‐colonial staple, a Nyungar technique archaeologically dated to at least 13 000 years BP. We measured the distance of M. dyeri populations to cultural landscape features and registered heritage sites. We also compared within‐population plant distribution characteristics to Nyungar occupation preferences around granite inselbergs. We found evidence of Nyungar influence on contemporary distribution of M. dyeri. Populations of M. dyeri occur close to surface water features in the west and granite outcrops in the east of Nyungar country, which corresponds closely to differential pre‐colonial patterns of Nyungar occupation. M. dyeri population frequency was negatively correlated with distance to registered Nyungar sites, and 75% of all M. dyeri populations occur within 3.2 km of a registered Nyungar site. We found no correlation between habitat availability and size of granite populations, but found that Nyungar occupation preferences in relation to ground surface aspect, slope and landform type correlated with intra‐population M. dyeri plant distribution, suggesting a mutualistic relationship with Nyungar people, has influenced the plant’s distribution. We suggest that contemporary M. dyeri distribution is therefore useful for interpreting past location‐specific Nyungar land practices to inform contemporary conservation management. Our findings demonstrate that along with edaphic, climate and other environmental factors, consideration of pre‐colonial human dispersal and land practices is important for plant conservation in Australia, particularly for taxa with prolonged use by humans. Further, we suggest that analyses of long‐lived Macrozamia elsewhere may be useful for interpreting past Aboriginal land practices.

Macrozamia dyeri（Zamiaceae）的当代分布与西澳大利亚州东南沿海的Nunggar占领模式有关

土著社会与植物的相互作用可能导致当代分布格局反映出这些关系，例如靠近占领点或运输路线的资源物种的集中。苏铁科植物Macrozamia dyeri的种子是西南澳大利亚西南部植物区的Nyungar First People的食物。通过在土壤或水中浸出来处理种子，可以对排毒前的主食进行排毒和保存，这是一种Nyungar考古学技术，其历史可追溯到至少1300年BP。我们测量了染色支原体的距离人口的文化景观特征和已注册的文化遗产。我们还将种群内植物分布特征与花岗岩Inselbergs附近的Nunggar职业偏好进行了比较。我们发现Nyungar对M. dyeri的当代分布有影响的证据。群M. dyeri到地表水在尼翁加赫国家，紧密地对应于尼翁加赫占领差动殖民前图案的东西，花岗岩露出设有发生密切。染色支原体种群频率与到登记的Nunggar站点的距离呈负相关，占所有染色支原体的75％人口位于一个注册的Nyungar厂区3.2公里内。我们没有发现栖息地的可利用性与花岗岩种群的大小之间存在相关性，但是发现与地表纵横比，坡度和地貌类型相关的Nunggar占领偏好与种群内M. dyeri植物分布相关，表明与Nyungar人群存在相互关系。影响了工厂的分布。我们建议当代M.因此，分布对于解释过去特定于地点的Nunggar土地做法，以为当代保护管理提供帮助。我们的研究结果表明，与环境，气候和其他环境因素一起，考虑殖民前人类的传播和土地惯例对于澳大利亚的植物保护，特别是对于人类长期使用的分类单元而言，至关重要。此外，我们建议对其他地方长期存在的Macrozamia进行分析可能有助于解释过去的土著土地惯例。
