Interacting effects of sand, slugs and jute drive community composition in direct-seeded urban wildflower meadows

Aim: Wildflower meadows support biodiversity in urban environments, whilst providing low-maintenance, amenity landscapes. By moving from international plant palettes to those that include species from threatened plant communities in meadows, we can reintroduce native species to urban landscapes and help achieve conservation objectives. Adapting horticultural techniques from Europe, we determined if such approaches could support the germination and establishment of grasses and wildflowers from critically endangered plant communities in Melbourne, Australia.
Location: Royal Park, Parkville, Victoria, Australia
Methods: We sowed seed of 27 species on soil capped with two depths of sand (10 mm and 80 mm) and site soil without sand to determine the impact of sand on weed emergence, slug grazing and growth of sown species. We quantified weed biomass and the time spent weeding unsown species from the emerging meadow. We also tested if covering the sites with a jute mesh enhanced sown species e..., Data was collected between April 2020 and July 2021 using field surveys of a direct sown native wildflower meadow in Royal Park in Melbourne Australia (37°47'34”S, 144°57'21”E). Data processing has included derivation of summary measures, including species richness (the sum of all sown species recorded in each subplot), diversity of the plant community (determined by calculating the Shannon index) and percentage cover classes (by aggregating percentage cover for each of sown species, unsown species, leaf and bare ground). , , # Data from: Interacting effects of sand, slugs and jute drive community composition in direct-seeded urban wildflower meadows

Supplementary data files for study “Interacting effects of sand, slugs and jute drive community composition in direct-seeded urban wildflower meadows”, providing data recorded on weeding time, weed biomass, sown plant abundance, cover and species richness as well as substrate characteristics as recorded in a designed, direct-seeded wildflower meadow in an urban park in Melbourne, Australia. The site was sown in April 2020 and the plant community was surveyed twice in the first year of establishment. Weed data was collected every second month over the course of this year.

All files are in .csv format.

研究目的：
野花草甸可支撑城市环境中的生物多样性，同时提供低维护的景观绿地。若将草甸植物配置从国际通用植物组合，调整为包含草甸受威胁植物群落物种的组合，便可将本土物种重新引入城市景观，助力实现保护目标。本研究借鉴欧洲的园艺栽培技术，旨在验证此类方法能否支持澳大利亚墨尔本极危植物群落的草本与野花的萌发与定植。

研究地点：
澳大利亚维多利亚州帕克维尔市皇家公园

研究方法：
本研究将27个物种的种子播种于覆盖两层厚度（10 mm与80 mm）沙层的土壤，以及无沙覆盖的原生样地土壤中，以探究沙层对杂草萌发、蛞蝓取食以及播种物种生长的影响。研究量化了杂草生物量，以及在新生草甸中拔除非播种物种所需的除草时长。本研究同时测试了使用黄麻网覆盖样地是否能够提升播种物种的[原文截断]。
本研究于2020年4月至2021年7月期间，通过对澳大利亚墨尔本皇家公园内直播本土野花草甸的野外调查采集数据（南纬37°47′34″，东经144°57′21″）。数据处理过程包括推导汇总统计量，其中涵盖物种丰富度（每个小样方内记录的所有播种物种总数）、植物群落多样性（通过计算香农指数（Shannon index）得到）以及盖度等级（通过汇总播种物种、非播种物种、枯落物与裸地的盖度得到）。
