历史沿革
鲍曼山野花保护区（Bowman’s Hill Wildflower Preserve）位于美国宾夕法尼亚州巴克斯县（Bucks County）的历史名镇新希望（New Hope）附近，坐落于皮德科克溪谷（Pidcock Creek Valley），占地 134 英亩，是美国唯一一座以本土植物为主题并获得美国博物馆联盟（American Alliance of Museums，AAM）认证的活体植物博物馆。保护区由鲍曼山野花保护协会于 1934 年发起设立，至今已有逾 80 年的主动管理历史；1989 年通过 AAM 正式认证，是全美约 60 座获此认证的植物园中第一座专注于本土植物收藏的机构。协会以”Bowman’s Hill Wildflower Preserve Association”名义代为托管约 60 种被列为稀有、受威胁或濒危的本土物种，使之成为面向公众的永久保育资产。
地质与生境
保护区之所以能在相对紧凑的范围内汇集 700 余种宾夕法尼亚本土植物（约占全州 2000 种本土植物的三分之一以上），核心源于其独特的地质构造：园区位于约 2.2 亿年前三叠纪形成的过渡地带，岩层涵盖向北的辉绿岩（diabase）山脊、烘烤变质的角页岩（hornfels）洼地以及皮德科克溪形成的河岸带，三类截然不同的土壤基质孕育出可识别的本土植物群落。地表则呈现成熟硬木林、开阔草甸、陡坡林缘、两处池塘与多处湿地等多样化栖境，春天野花铺地、夏季林荫蔽日、秋季浆果累累，冬天亦有常绿与越冬鸟类可循。约 5 英里长的徒步径贯穿森林、草甸与水道，沿线设置帕里小径（Parry Trail）和驴蹄草小径（Marshmarigold Trail），方便访客近距离观察稀有物种。
活体收藏与保育
保护区的活体植物收藏（Living Museum Collection）由永久、教育、研究三类组成，共收录约 200 种具特殊保育或教育价值的本土物种，由策展人及其团队持续采集、繁殖与更新。所有入藏物种均经过编目、追踪与公开解读，让访客能在自然生境中理解本土植物的群落结构与生态角色。永久类收藏由 60 种被列为稀有、受威胁或濒危的宾州本土物种组成，由协会以公众信托方式代为守护；教育类收藏旨在引导本地社区认识本土植物；研究类收藏则与宾州自然保护资源部（PA DCNR）、自然土地信托（Natural Lands Trust）等机构合作，用于物种回归与栖息地修复研究。协会亦与伦纳德·”鲍曼”·理查兹博士等先驱合作，自创立之初便坚持”就地保护”原则，使整座保护区成为一个可持续管理的活体博物馆。
苗圃与教育
保护区内的本土植物苗圃（Native Plant Nursery）每年面向公众供应 200 余种高品质本土苗木，所售种子大多采自园区及周边本地种源，特色种类包括红花半边莲（Lobelia cardinalis）、弗吉尼亚风铃草（Mertensia virginica）、马利筋（Asclepias tuberosa）等宾州本土多年生花卉。园区常年开放导览与自然教育课程：从学龄前儿童的感官探索、家庭周末活动，到面向园艺师与生态学者的高阶研讨会，主题涵盖”为何本土植物重要””植物群落的动态演替””入侵物种识别与控制”等。会员可享受免费入园、自然学家导览（每年 4 月至 10 月，每人 3 美元）、双叶草书店（Twinleaf Book & Gift Shop）折扣以及春季苗圃开幕活动优先入场等权益。
参观与社区
保护区全年向公众开放：4 月至 6 月每日 9:00–17:00 开放、7 月至次年 3 月周三至周一开放（周二闭园），感恩节、平安夜、圣诞节、除夕与元旦闭园。成人门票 12 美元，65 岁以上长者、全日制学生、军人与退伍军人 9 美元，5–17 岁儿童 6 美元，5 岁以下儿童与会员免费；ACCESS / SNAP / EBT 等项目持有人凭有效证件可购 2 美元优惠票。园区每月第一个星期五、地球日（4 月 22 日）、宾州本土物种日（5 月 20 日）、国家 paw paw 日（9 月 17 日）免费开放。访客可使用专为行动不便人士设计的高尔夫球车导览（Access Cart Tour），也可通过志愿者项目成为园区自然保育的参与者，园区通过这一长期社区网络把生态修复、自然教育与本地康养紧密连结。
Historical Evolution
Bowman’s Hill Wildflower Preserve, located in the historic Pidcock Creek Valley of Bucks County, Pennsylvania, near the village of New Hope, is the only accredited living museum in the United States dedicated exclusively to native plants. Founded in 1934 and stewarded by the Bowman’s Hill Wildflower Preserve Association, the 134-acre Preserve has been actively managed for more than eight decades. It received formal accreditation from the American Alliance of Museums (AAM) in 1989, becoming the first native plant collection in the nation to be recognised among approximately 60 AAM-accredited botanical institutions. The Association holds roughly 60 species classified as rare, threatened or endangered in public trust, fulfilling a long-standing mission to promote native plant conservation in the Delaware Valley region.
Geology and Habitats
The Preserve owes its botanical richness to a unique geological inheritance: its 134 acres sit across three distinct bedrock zones shaped during the Triassic Period some 220 million years ago, including a north-facing diabase ridge, a swale of baked hornfels overlying the original shale, and the riparian corridor of Pidcock Creek. Together these substrates support mature hardwood forest, meadow, steep hillsides, ponds and a mosaic of wetlands, sustaining more than 700 of Pennsylvania’s 2,000 native plant species—roughly one third of the state’s flora. About five miles of maintained trails, including the Parry Trail and Marshmarigold Trail, thread through the property and invite visitors to observe seasonal blooms, resident birds, pollinators and the Preserve’s signature wildflower displays throughout the year.
Living Museum Collection
The Preserve’s Living Museum Collection is curated into permanent, education, and research categories and currently encompasses about 200 species of conservation or pedagogical significance. Every accessioned plant is catalogued, tracked and publicly interpreted so that visitors can engage with native plant communities in their natural context. The permanent collection safeguards roughly 60 species classified as rare, threatened or endangered, while the education collection introduces visitors to characteristic native species of the Delaware Valley ecoregion, and the research collection supports active propagation and reintroduction work in partnership with the Pennsylvania Department of Conservation and Natural Resources (PA DCNR), the Natural Lands Trust and other regional organisations. Periodic phytoblitz surveys refine the Preserve’s records and inform ongoing stewardship.
Nursery and Education
The on-site Native Plant Nursery offers more than 200 species of high-quality native plants, propagated largely from locally sourced seed, including signature species such as cardinal flower (Lobelia cardinalis), Virginia bluebells (Mertensia virginica) and butterfly weed (Asclepias tuberosa). Plants grown at the Preserve are also sold to home gardeners, allowing the public to extend the Preserve’s conservation mission into their own backyards. Educational programming spans preschoolers through professionals, with guided naturalist walks from April through October (US $3 per person), school and scout group tours, and lectures on native plant communities, pollinator ecology and invasive species management. Members receive free admission, discounts at the Twinleaf Book & Gift Shop, and early access to the annual Spring Nursery Opening weekend.
Visiting and Community
The Preserve welcomes visitors year-round: from April through June it is open daily 9 am – 5 pm, and from July through March Wednesday through Monday (closed Tuesdays), with closures on Thanksgiving Day, Christmas Eve, Christmas Day, New Year’s Eve and New Year’s Day. General admission is US $12 for adults, US $9 for seniors aged 65 and above, full-time students with ID, and military or veterans, US $6 for children aged 5 through 17, and free for children under 5 and members. Free admission is offered on the first Friday of every month, Earth Day (April 22), Pennsylvania Native Species Day (May 20) and National Paw Paw Day (September 17). An Access Cart Tour supports visitors with limited mobility, and a robust volunteer programme—from corporate days to teen naturalists—anchors the Preserve’s role as a regional hub for conservation, education and community well-being.
