美国霍尔登树木园（The Holden Arboretum）坐落于俄亥俄州基尔兰（Kirtland），是美国最大的树木园之一，占地超过3600英亩（约1457公顷）。园内设有600英亩的专类园区与花园，其余为天然林地与生态保护区，收集了来自79个科的9400余种木本植物。
历史沿革
1931年，矿业大亨阿尔伯特·费尔柴尔德·霍尔登（Albert Fairchild Holden, 1866-1913）为纪念已故妻子和女儿创立了霍尔登树木园。1937年首次对公众开放，2014年与克利夫兰植物园合并，现以霍尔登森林与园艺机构（Holden Forests & Gardens）名义运营。
主要景点
霍尔登树木园的标志性景点包括Murch树冠步道（Murch Canopy Walk），带领游客穿行于森林树冠之间；以及卡尔伯勒瞭望塔（Kalberer Emergent Tower），提供周边景观的全景视角。园内还有伊利亚特与琳达·佩恩杜鹃花发现花园（Eliot and Linda Paine Rhododendron Discovery Garden）、展示花园（Display Garden）和康宁游客中心（Corning Visitor Center）等重要设施。
天然林地
斯泰宾斯峡谷（Stebbins Gulch）是霍尔登树木园最珍贵的天然林地区域，是俄亥俄州东北部保存最完好的自然历史保护区之一，暴露的岩层揭示了该地区跨越3亿年的地质历史。天然林地涵盖多样的森林、草地和水域生态系统，横跨莱克县和乔治亚县。
科研保护
霍尔登森林与园艺机构在科研方面投入显著：朗植物与环境科学中心（Long Center for Plant and Environmental Science）支撑前沿研究，霍尔登种子银行（Holden Seed Bank）为植物保护做出贡献。此外，机构还运营大卫·利奇研究站（David G. Leach Research Station）并参与大型景观恢复项目。
History
In 1931, mining magnate Albert Fairchild Holden (1866–2013) established the Holden Arboretum as a living memorial to his deceased wife and daughter. The site opened to the public in 1937. In 2014, the Holden Arboretum merged with the Cleveland Botanical Garden to form Holden Forests & Gardens, combining two of Northeast Ohio’s most significant botanical institutions.
Major Attractions
The Holden Arboretum features iconic attractions including the Murch Canopy Walk, which takes visitors through and above the forest canopy for immersive views of the tree canopy and streams below, and the Kalberer Emergent Tower, offering sweeping panoramic vistas of the surrounding landscape. Other highlights include the Eliot and Linda Paine Rhododendron Discovery Garden, the Display Garden, and the Corning Visitor Center.
Natural Areas
Stebbins Gulch is considered the crown jewel of Holden’s extensive natural areas — one of the most unspoiled natural history preserves in Northeast Ohio, where exposed bedrock reveals 300 million years of geological history. The natural areas encompass diverse forests, meadows, and lake habitats across Lake and Geauga Counties, forming a patchwork of old-growth forests, young post-agriculture forests, and wetlands.
Science and Conservation
Holden Forests & Gardens is committed to scientific research and plant conservation. The Long Center for Plant and Environmental Science supports cutting-edge research, while the Holden Seed Bank contributes to plant conservation efforts. The organization also operates the David G. Leach Research Station and participates in large-scale landscape restoration projects across the Great Lakes region.
