Replication data for: The natural capital of Grappler Peninsula: a comparative study of old and secondary growth coastal temperate rainforest

The one-hectare second growth SI/MAB plot was recensused August 1-20, 2007, and a second plot of old growth cedar forest was established and censused following Environment Canada's Ecological Monitoring and Assessment Network or EMAN protocol. Data is presented here. For a comparison of canopy cover in the SI/MAB plot between 2001 and 2007, see the 2007 student report. Both plots are located on the north side of Grappler Inlet near Bamfield, British Columbia on property owned and administered by the Bamfield Marine Sciences Centre. The centre of the SI/MAB plot has GPS coordinates 48°50’19.00”N, 125°08’02.00”W (48.83861111, -125.13388889), and the centre of the EMAN plot has GPS coordinates 48°50’05.00”N, 125°07’45.00”W (48.83472222, -125.12916667). Both plots are divided into 25 quadrats (20m x 20m). Live and dead standing trees were censused for species, DBH (diameter at breast height) and status (physical condition). Only trees with a DBH ≥ 8 cm were censused in the EMAN plot to avoid the detrimental effects of nailing tags into the trunks of small trees. This same principle was applied to new trees in the SI/MAB plot but none were found. Data was collected by students in the Coastal Biodiversity and Conservation course taught by Dr. Tom Herman and Dr. Barb Beasley July 23-Aug 31, 2007 with Teaching Assistant Ben Starkhouse.

本1公顷次生林SI/MAB样地于2007年8月1日至20日完成重测；另一处老龄雪松林样地则依照加拿大环境部生态监测与评估网络（Environment Canada's Ecological Monitoring and Assessment Network, EMAN）规程完成设立与普查，本数据集即收录相关数据。如需对比2001年与2007年SI/MAB样地的冠层覆盖率，请参阅2007年学生研究报告。两处样地均坐落于不列颠哥伦比亚省班菲尔德附近的格拉普勒湾北侧，地块由班菲尔德海洋科学中心所有并管理。SI/MAB样地中心的GPS坐标为48°50’19.00"N，125°08’02.00"W（十进制坐标：48.83861111, -125.13388889）；EMAN样地中心的GPS坐标为48°50’05.00"N，125°07’45.00"W（十进制坐标：48.83472222, -125.12916667）。两处样地均被划分为25个20m×20m的样方。普查内容包括存活与枯立木的物种、胸径（diameter at breast height, DBH）及生理健康状况。鉴于在小树树干上钉挂标签会造成不利影响，EMAN样地仅对胸径≥8cm的树木开展普查；该原则同样适用于SI/MAB样地的新增树木，但本次普查未发现新增个体。本数据集由汤姆·赫尔曼（Tom Herman）博士与芭布·比斯利（Barb Beasley）博士授课的“海岸生物多样性与保护”课程学生，于2007年7月23日至8月31日完成数据采集，教学助理为本·斯塔克豪斯（Ben Starkhouse）。
