★涵蓋964種，迄今最完整的台灣蕨類植物百科★台灣地處亞熱帶，擁有驚人的石松類與蕨類多樣性。全世界已知的石松類與蕨類植物約一萬兩千餘種，相較於歐洲約175種，北美約441種，小小的台灣卻有超過900多種，其中約三分之一為稀有或特有物種。從海岸林到高山冰河遺跡地帶，複雜的地形與垂直氣候梯度，使這座島嶼成為全球石松類與蕨類植物密度極高的地區。然而，棲地破壞與過度採集威脅著這些珍貴的資源。隨著開發壓力與園藝、藥用需求擴大，不少具觀賞價值或藥效的種類正快速消失。許多珍稀蕨類仍暴露在不受控制的風險中，岌岌可危，亟需保育。作者以近30年的調查、拍照及採集，進入深山老林，山巔水媚，只為記錄台灣石松類與蕨類的傳奇寶庫，每一幅影像、每一筆分布圖，新紀錄或新種的發現，都訴說著數十年的軌跡。本書不僅是一本植物圖鑑，更是一封寫給島嶼自然多樣性與生態韌性的情書。【審訂】農業部林業試驗所前植物園組組長 邱文良【推薦】國立臺灣師範大學生命科學系名譽教授 王震哲《台灣原生蘭生態觀察圖鑑》作者 余勝焜農業部林業試驗所所長 曾彥學（依姓氏筆畫排序）【自序】我出生在新北市雙溪的農村，家中十個兄弟姊妹中排行第九，因此在網路上以「九妹」自稱。小學畢業後便離鄉至台北工作，直到多年後才再度拾起書本，以半工半讀的方式完成空中商專的學業。1996年，我因緣際會加入主婦聯盟自然步道擔任綠人（解說員），並參與芝山岩文化史跡公園的調查工作，那段時間是我初次接觸蕨類。當時只是跟著前輩「看一種、學一種」，並未系統性學習，即使已經認得200多種蕨類，仍不知道什麼是「檢索表」。回想起來，那是一段既困難又有趣的歷程。或許是自幼生長在四面環山的鄉間，植物無所不在，耳濡目染之下，培養出對植物的高度敏感，讓我能很快進入狀況並持續累積知識。1997年，我有幸成為陽明山國家公園的解說志工。10年間，除了值勤，也和夥伴們在山林間學習、探索，這段日子為往後的研究奠定了厚實基礎。1999年自然步道協會成立，理事長林俶圭老師開設了蕨類入門課程，我才真正認識到系統化的學習方式。其後我擔任協會蕨類小組組長，與大家一起出野外、辦讀書會，逐步建立起完整的基礎概念。那時還沒有如今這般便利的圖鑑與網路資源，所幸有郭城孟老師與其研究室給予指導與協助，讓我養成「走過必留下名錄」的習慣，也才有本書的分布圖。然而，我的學習過程也遭遇不少瓶頸，一度萌生放棄之念。2001

無需花大錢，就能動手玩科學。科學探究能力是「依邏輯架構，從做中學習」的學門。不是漫無目標的創意發想，而是透過食譜式實驗活動，先熟悉操作過程，了解各項工具的特性與限制，練習數據的收集、紀錄與整理方法，再依不同任務，探討指定變因與規劃實驗設計，或是自行尋找變因與研究方向。本書架構•實驗設計。•研究資料的種類、數據處理與圖表。•20項動手做科學探究活動。•科學報告撰寫。本書特色•器材容易準備且便宜，操作門檻低，活動場地限制小。•針對各主題設計初階、進階與高階的探究任務，逐步提升挑戰性。•橫跨物理、化學、生物及數學領域，不侷限單科，學習更加全面。•兼具質性比較與量化分析訓練，藉由問題討論培養統整能力。•各探究任務皆提供相關學理說明，增加探討深度。「這本書裡有各種有趣的實驗、精準正確的學理探索，更有蔡老師對於科學研究的滿腔熱血，期待大家跟隨艦長的腳步，一起動手做科學。」--龔雍任/臺中市立臺中一中生物科教師「從事探究教學與專題研究的教育者，一定不能錯過的好書。」--阿簡老師/新竹市立光華國中教師
