Harvey Monroe Hall Research Natural Area trail monitoring study: 1993 vegetation and trail conditions

The Harvey Monroe Hall Research Natural Area (HMHRNA), located in the Inyo National Forest in California, was established in 1933. In 1993, vegetation surveys were used to monitor human impacts on trails using the Limits of Acceptable Change (LAC) protocol. This data publication contains plant inventories and notes regarding trail impacts along 6 transects bisecting trails across 3 drainages in the HMHRNA. Also included are photographs of transect start points, end points, and an overview of each transect. These data were intended to provide a baseline for future comparisons to determine whether human impacts have been increasing, decreasing, or staying the same.
The purpose of this study was to apply the LAC system for wilderness planning in the HMHRNA. Vegetation damage along trails was used as the indicator of degree of impact.
These data were published on 09/08/2023. On 10/13/2023, journal article link updated and a bounding coordinate corrected.

哈维·门罗·霍尔研究自然保护区（Harvey Monroe Hall Research Natural Area，HMHRNA）坐落于美国加利福尼亚州因约国家森林公园，于1933年正式设立。1993年，研究团队采用可接受变化极限（Limits of Acceptable Change，LAC）规程，通过植被调查监测步道受人类活动的影响情况。本数据集包含HMHRNA内3条流域沿线6条横穿步道的样带周边的植物名录，以及步道影响相关记录；此外还涵盖各条样带的起点、终点照片，以及每条样带的整体概览照片。本数据集旨在为后续对比研究提供基准基线，以判断人类活动对步道的影响程度是呈上升、下降还是维持不变。
本研究的核心目标是将LAC体系应用于HMHRNA的荒野规划工作，以步道沿线植被受损情况作为影响程度的衡量指标。
本数据集于2023年9月8日正式发布；2023年10月13日，数据集更新了关联期刊论文的链接，并修正了边界坐标。
