新西兰 原生兰花小组 NZNOG – 新西兰原生兰花研究团体

团体概况与宗旨

新西兰原生兰花小组 (New Zealand Native Orchid Group, 缩写 NZNOG) 是新西兰全国性的原生兰花业余研究与保护组织, 会员遍及新西兰南北两岛, 也有部分海外成员长期跟进. 团体由原生兰花爱好者自发组成, 主要开展观察、分类研究与野外保育工作. 出版物《NZNOG Journal》季刊一年四期 (二月、五月、八月、十一月出版), 是会员之间交流新发现、讨论分类修订与记录科学进展的核心平台, 不少新物种的早期报告都先在期刊上披露. 团体年度大会 (AGM) 通常安排在十月至十二月, 配合野外实地考察一同举行, 周末的安排便于更多会员从各地赶来一同观赏花期.

活动形式与会员参与

除年度大会的正式野外考察外, 团体还常年组织不拘形式的地方性短途活动, 以及为期一周左右的较远地区「跟随」考察, 后者一般通过电子邮件群发召集. 考察完全由参与者自行安排交通与住宿, 适合不同体力条件的会员一同参与. 团体在全国设有十四个区域联系人, 分别负责 Far North、Mid Northland、Auckland、Waikato、Bay of Plenty、East Coast、Hawkes Bay、Taranaki、Wairarapa、Wellington、Nelson/Marlborough、Canterbury、Otago、Southland 与 Stewart Island, 会员可以就近咨询当地适合前往的兰花分布点与花期. 入会费按四档计算: 新西兰境内会员年费 60 新元, 海外会员同样 60 新元, 新西兰学生会员与电子版会员各 25 新元, 订阅周期为每年十月一日至次年九月三十日.

学术合作与外部联络

团体与澳大利亚的 Australasian Native Orchid Society (ANOS) 及其各州分会保持长期联系, 方便会员前往澳大利亚时查阅当地的兰花出版资料. 在研究层面, 团体每年向兰花研究项目 (特别是面向学生的研究) 提供小额经费资助, 部分项目由新西兰国家博物馆 Te Papa 的植物学家 Carlos Lehnebach 监督指导, 会员们通常会为这些项目提供本地物种分布与花期的一手观察资料. 团体从创立之初就持续开展物种分布制图与花期记录工作, 这些数据后来成为「新西兰兰花物种志」在线数据库的重要基础, 也整合进 iNaturalist NZ 等公民科学观测平台, 供研究者与爱好者共同查阅.

物种分类与保护现状

新西兰原生兰花的栖息地跨度从海岸一直延伸到高山带, 主要类型包括 manuka 与 kanuka 灌丛下的开阔地带、kauri 森林、潮湿的苔藓坡面、低地原生林以及高山灌丛与海岸带等, 不同环境孕育了 sun orchid (Thelymitra)、绿帽兰 (Pterostylis)、蜘蛛兰 (Corybas)、鸟兰、薯兰等多个类群. 在保护层面, 团体遵循 de Lange 等 (2018) 提出的新西兰本土维管植物受威胁分类体系, 该体系下 Caleana minor、Calochilus herbaceus、Corybas carsei 等七种被列为「全国极危」, Drymoanthus flavus、Prasophyllum hectorii、Spiranthes novae-zelandiae 等六种被列为「数量下降」, 另有 Caladenia、Corybas、Thelymitra 等二十余种列入「天然罕见」类. 团体的保护准则强调「不挖掘、不采摘」, 鼓励野外记录与上报稀有物种, 必要时通报新西兰保育部 (DOC).

出版物与公众资源

团体近年推出的代表性出版物包括 2021 年第三版的《A Pocket Guide to the New Zealand Native Orchids》便携手册, 收录近年新发表的物种, 每种配以彩色照片与分布图, 售价 40 新元 (含城市邮费 7.70 新元, 乡村 13.40 新元). 此外 Ian St George 整理的《Colenso’s Collections》以新西兰传教士 William Colenso 在十九世纪采集的植物档案为核心, 引用了 Te Papa 馆藏 Colenso 标本与 Hamlin 的研究笔记, 同时收录他与英国皇家植物园 Kew 之间从 1839 年起的通信内容, 印刷本与 PDF 版本均可获取, PDF 版售价 10 新元. 该会出版物页面另有四十余份历史期刊与早期指南的 PDF 资源, 多数免费向公众开放, 可在该会出版物主页上查询目录.

Origins & Purpose

The New Zealand Native Orchid Group (NZNOG) is a nationwide amateur society dedicated to the observation, study, and conservation of New Zealand’s native orchids. Its members are spread across both islands, with a small number based overseas. The Group publishes a quarterly journal, the NZNOG Journal, four times a year (February, May, August, and November), which serves as the main forum for reporting new finds, debating taxonomic revisions, and recording scientific progress. Many new species have first been described in the journal’s pages. The Annual General Meeting is held between October and December at a rotating venue, timed to coincide with flowering peaks so that field trips can show members as many orchids in bloom as possible.

Field Activities & Membership

Beyond the AGM weekend, members organise informal local day trips throughout the year, as well as longer “tag along” excursions of a week or so to more distant regions, advertised by email. Participants make their own travel and accommodation arrangements. Fourteen regional contacts cover the country from Far North and Mid Northland down through Auckland, Waikato, Bay of Plenty, East Coast, Hawkes Bay, Taranaki, Wairarapa, Wellington, Nelson/Marlborough, Canterbury, Otago, Southland and Stewart Island, advising on access and flowering times. Annual subscriptions are NZD 60 for New Zealand members, NZD 60 for overseas members, NZD 25 for New Zealand students, and NZD 25 for the electronic-only option. The subscription year runs from 1 October to 30 September.

Research Links & External Networks

The Group maintains a long-standing link with the Australasian Native Orchid Society (ANOS) and its state branches, which is helpful for members planning to look for orchids in Australia. On the research side, the society funds small grants, particularly for student projects, several of which have been supervised at Te Papa by botanist Carlos Lehnebach; members frequently contribute field observations of distribution and flowering phenology to support this work. From its early days the Group has been active in mapping species distributions and recording flowering times, building a national database that now feeds platforms such as iNaturalist NZ where researchers and enthusiasts can browse observations jointly.

Habitats & Conservation Status

New Zealand’s native orchids occupy habitats ranging from coastal dunes to alpine zones, with key environments including open ground beneath manuka and kanuka scrub, kauri forest, dripping mossy banks, lowland native forest, and high country tussock. These support diverse groups such as sun orchids (Thelymitra), greenhoods (Pterostylis), spider orchids (Corybas), bird orchids, and potato orchids. The Group follows the threat framework of de Lange et al. (2018) for indigenous vascular plants. Under that system seven species including Caleana minor, Calochilus herbaceus, and Corybas carsei are listed as Nationally Critical, six such as Drymoanthus flavus, Prasophyllum hectorii, and Spiranthes novae-zelandiae as Declining, and more than twenty as Naturally Uncommon. The Group’s code of conduct emphasises observation, photography, and reporting rare finds to the Department of Conservation rather than collecting.

Publications & Public Resources

Among recent titles, the 2021 third edition of A Pocket Guide to the New Zealand Native Orchids updates the species list with recently described taxa, each accompanied by colour photographs and distribution maps. It is priced at NZD 40, with postage of NZD 7.70 for urban addresses and NZD 13.40 for rural delivery within New Zealand. Ian St George’s Colenso’s Collections brings together archival material relating to missionary William Colenso’s nineteenth-century botanical work, drawing on Te Papa’s herbarium holdings and Bruce Hamlin’s research notes, together with transcriptions of letters Colenso wrote to Kew between 1839 and his death in 1899. A print edition is available on request and a PDF version is sold for NZD 10. The Group’s publications page also lists more than forty historical journal issues and earlier guides in PDF form, many of which are freely accessible to the public.
