Season and interval of burning and cattle exclusion in the southern Blue Mountains, Oregon: Environmental attributes

These data document environmental variables including overstory canopy cover, O horizon depth, ground cover and soils for a prescribed burning study with unburned controls on the Malheur National Forest in the southern Blue Mountains of Oregon. The original prescribed fires were conducted in the fall of 1997 and spring of 1998 and were repeated at two intervals, five and fifteen years. Five year interval reburns have been repeated three times (four burns total) and the fifteen year interval a single time (two burns total). Data include environmental conditions prior to and following the last reburns except for soils data which were collected prior to the last reburns only. Specifically, this data publication includes overstory tree canopy cover data from the 10-meter radius plots, ground cover data (litter, rock, bare soil and coarse woody debris) from the 1 x 1 meter quadrats, O horizon depth data from the 10-meter radius plots, and soils data (e.g. carbon, nitrogen and phosphorous concentrations, pH and bulk density) from 2012.Environmental data were collected to examine the impact of season of burn (fall, spring and no burning) at two intervals (5 and 15 years), and (2) season of burn (fall, spring and control), 5-year interval reburning and cattle grazing.Original metadata date was 08/28/2017.

本数据集详细记录了环境变量，包括林冠层覆盖度、O层深度、地表覆盖和土壤等，这些数据与在俄勒冈州南部蓝山脉的马拉赫国家森林进行的预定燃烧研究相关，其中包含未燃烧的控制组。原始的预定燃烧活动分别在1997年秋季和1998年春季进行，并在两个时间间隔内重复进行，分别为五年和十五年。五年间隔的重新燃烧已重复三次（总计四次燃烧），而十五年间隔的燃烧仅进行了一次（总计两次燃烧）。数据包括最后一次重新燃烧前后的环境条件，但土壤数据仅收集了最后一次重新燃烧之前的信息。具体而言，本数据出版物包括10米半径样地中的林冠层树木覆盖度数据，1 x 1米方格中的地表覆盖数据（包括碎屑、岩石、裸土和粗木质残骸），10米半径样地中的O层深度数据，以及2012年收集的土壤数据（例如碳、氮和磷浓度、pH值和容重）。收集环境数据旨在探究燃烧季节（秋季、春季和无燃烧）在两个时间间隔（5年和15年）内，以及（2）燃烧季节（秋季、春季和控制）、五年间隔的重新燃烧和放牧对环境的影响。原始元数据日期为2017年8月28日。2021年5月4日对关键词进行了微小的元数据更新。
