缘起与组织身份

Calflora 1994 年由 Dr. Ann Dennis 在美国林务局（US Forest Service）的支持下启动, 初版是 8 个字符的 DOS 文件名, 一份供研究者下载到本地电脑的物种信息数据库; 早期合作方包括加州大学伯克利分校数字图书馆研究项目（UC Berkeley Digital Library Research Project）及图书馆员 Tony Morosco; 1990 年代后期网页化, 2000 年注册成为 501(c)(3) 非营利机构, 2003 年由开发者 John Malpas 进一步重写网站; 总部位于加州伯克利（Berkeley, CA）。

数据库规模与覆盖范围

Calflora 是加州野生植物相关数据最完整的公开数字图书馆, 数据来源包括标本馆（Consortium of California Herbaria, CCH）、加州鱼类与野生动物部（CDFW）植被制图项目与自然多样性数据库、加州本土植物学会（CNPS）及个体观察者; 数据库收录超过 4 百万条 occurrence 记录、约 8,000 种加州野生植物、3.1 百万条个人观察, 每年承接约 100 万次检索, 10,000 名注册观察者贡献数据。

主要查询工具与应用

Calflora 提供面向公众与专业人士的多类在线工具: “What Grows Here?” 帮助查询某地点可观察到的植物种类, “Planting Guide” 允许按地点、低耗水、耐荫、河岸等条件检索适合本地后院的原生植物, “Weed Manager” 服务于入侵植物早期识别与清除项目, “Observation Search” 支持按生命型、生长年限、县域等多维度筛选观察记录; 还提供 Android 与 iOS 智能手机应用、Great Places 收录 150 多个观察加州野花的最佳地点; “My Calflora” 与 “Add Observations” 支持个人观察记录与团队协作。

关联项目与外部数据互通

Calflora 与多个机构实现数据互通: 接入 Jepson eFlora 与 USDA PLANTS 提供分类与描述信息, 接入加州入侵植物委员会（Cal-IPC）提供非本地植物数据, 与 NRCS（USDA 自然资源保护局）合作维护 eVegGuide（electronic Vegetative Guide）子项目, 当前版本 5.11.2, 2024 年 6 月发布, 含 “Monarch Habitat” 帝王蝶栖息地选择标准; 资助渠道包括个人捐赠、公司配捐、遗产捐赠规划及 IRA 账户合格最低分配额（RMD）慈善赠与。

董事会、培训与公众参与

Calflora 由志愿董事会治理, 主席为南加州植物学家与专业园艺师, 与加州本土植物学会（CNPS）及加州入侵植物委员会（Cal-IPC）长期合作, 关注南海岸地区稀有植物保育与入侵植物早期发现; 科学项目董事于 2018 年加入董事会, 团队还包括多位负责数据工程、杂草管理与筹款的顾问; Calflora 提供面向团体的现场培训, 另有 YouTube 教程、Google Groups 用户社区与每项工具内置帮助页面。

Origin and Organizational Identity

Calflora was founded in 1994 by Dr. Ann Dennis with support from the US Forest Service, beginning as an 8-character DOS filename database of species information that researchers could download to their personal computers; early collaborators included the UC Berkeley Digital Library Research Project and librarian Tony Morosco; the project moved to the web in the late 1990s, was incorporated as a 501(c)(3) nonprofit in 2000, and the website was further revised in 2003 by developer John Malpas; the organization is headquartered in Berkeley, CA.

Database Scale and Coverage

Calflora is the most complete public digital library of California wild plant data, drawing on the Consortium of California Herbaria (CCH), the California Department of Fish and Wildlife (CDFW) Vegetation Mapping Project and Natural Diversity Database, the California Native Plant Society (CNPS), and individual observers; the database holds more than four million occurrence records, approximately 8,000 California wild plant taxa, and 3.1 million personal observations, with about one million searches served each year and roughly 10,000 registered observers contributing data.

Main Query Tools and Applications

Calflora provides a suite of online tools for both public and professional users: “What Grows Here?” answers what plants can be observed at a chosen location; the Planting Guide lets visitors filter California native plants by location, low water, shade, or riparian conditions to find species suitable for a home garden; the Weed Manager supports early detection and rapid response projects for invasive plants; and Observation Search supports multi-dimensional queries by lifeform, duration, county, and other criteria; Android and iOS smartphone apps, the Great Places directory of 150-plus viewing sites for California wildflowers, and “My Calflora” with “Add Observations” round out the user-facing suite for individual record-keeping and team collaboration.

Partner Projects and External Data Sharing

Calflora links directly to the Jepson eFlora and USDA PLANTS for taxonomic and descriptive information, to the California Invasive Plant Council (Cal-IPC) for non-native plant data, and to the NRCS eVegGuide (electronic Vegetative Guide) sub-project maintained in cooperation with USDA NRCS; the current eVegGuide release is version 5.11.2 published in June 2024, adding a Monarch Habitat plant selection criterion; funding channels include individual donations, corporate matching gifts, planned giving, and qualified IRA charitable distributions.

Board, Training, and Public Participation

Calflora is governed by a volunteer Board of Directors, currently chaired by a Southern California botanist and professional horticulturist with long affiliations with the California Native Plant Society (CNPS) and the California Invasive Plant Council (Cal-IPC), focused on rare plant conservation and early detection of invasives in the South Coast region; the Science Director joined the Board in 2018, and the team includes additional staff handling data engineering, weed management, and fundraising; Calflora offers in-person training sessions for groups, supplemented by YouTube tutorials, two Google Groups user communities, and per-tool help pages.
