計畫前2 年以普遍性採集為主，冀能先將容易取得之種類提供分析，並於第3 年採特殊種類之重點採集方式。所採集樣品之證據標本，存放於臺灣大學植物學系標本館（TAI）。由於部份族群零散，或是數量偏少，或位在保護區域內，為了避免對自然環境產生衝擊，對於部份個體較小或數量較少之種類，嘗試進行移植於溫室中栽植，分多採收其地上部份，以免影響野外植株的生存。目前幾個稀有種類，如哈氏狗脊蕨、傅氏三叉蕨、突齒蕨等，即以此一方式進行材料之搜集。 分析所採材料之分佈類型，其遍佈全臺各主要林帶如高山寒原、亞高山針葉林帶、冷溫帶針葉林帶、涼溫帶針闊葉混合林帶、暖溫帶闊葉林帶、亞熱帶闊葉林帶，以及熱帶及海岸地區，而以北部低海拔亞熱帶闊葉林之種類為最多。採集地點除臺灣北部地區（包括臺北、桃園、新竹、苗栗），並往東部擴張，以採到更多的種類，有些則是取自栽培植株。 During the first tow years of this project we mainly collected common species just as the first year in order to supply the analysis quickly. On the third year we emphasized on collecting special taxa. All the specimens conserved in TAI. The populations of these species are small or scattered, and some of them are located at protected areas. To avoid impact on natural environments, we tried to transplant some rare or small-sized species in green house to cut the aerial portion of the plants several times. We have collected some rare species in this way, including Woodwardia harlandii Hook., Tectaria fauriei Tagawa, and Pteridrys cnemidaria (Christ) C. Chr. & Ching. After analyzing the distribution pattern of species what we collected, the distribution of them scatter on the most vegetation type in Taiwan, for example tundra, subalpine coniferous forest, cold temperate coniferous forest, cool temperate mixed forest, warm temperate broad-leaved forest, subtropical broad-leaved forest, and the most species are from low altitude subtropical broad-leaved forests in northern Taiwan. To get more materials, we also collected plants in eastern part of Taiwan, or got them from cultivated individuals.
