Monitoring management actions for Dracocephalum ruyschiana

This project contains data collected in conjunction with the project Monitoring effect of management actions on Dracocephalum ruyschiana in Norway. The project was established in 2023 and aims to study the effects of management practices on Dracocephalum ruyschiana, a threatened (VU) and prioritised species. A monitoring locality was established at a D. ruyschiana population near Nordre Horgen, Frogn, Viken.

Here, 20 1x1 m vegetation plots where established:
- 5 plots with D. ruyschiana that were later mowed
- 5 plots without D. ruyschiana that were later mowed
- 5 plots with D. ruyschiana that were not mowed
- 5 plots without D. ruyschiana that were not mowed

At each plot, the cover of all vascular plants, the cover and presence of D. ruyschiana, and other vegetation parameters (e.g., vegetation cover, vegetation height) was recorded.

本项研究数据集汇集于与挪威地区管理措施对龙牙草（Dracocephalum ruyschiana）监测效果评估项目相结合的采集工作之中。该项目始于2023年，旨在探究管理措施对龙牙草这一濒危（VU）且优先保护的物种所产生的影响。监测地点设于挪威维肯郡弗罗恩市北霍根地区附近的龙牙草种群中。在该地点，共设立了20个1x1米的植被样地：
- 其中5个样地包含龙牙草，后经刈割处理；
- 5个样地不含龙牙草，后经刈割处理；
- 5个样地包含龙牙草，未经刈割；
- 5个样地不含龙牙草，未经刈割。
在每个样地中，记录了所有维管植物的覆盖度、龙牙草的覆盖度和存在情况，以及其他植被参数（例如植被覆盖度、植被高度）。
