地理的範囲
Food Forest Haarzuilens is an area of approximately 6 hectares, located along the Haarrijnse Plas, near Haarzuilens on the western side of Utrecht. The reference area lies to the west of the food forest. The history of both the food forest and the reference area is the same: they were formerly agricultural grasslands and have been owned by Natuurmonumenten since 2007. Since 2015, the food forest has been developed on this grassland. In the reference area, the grassland is being impoverished: a management strategy aimed at developing species-rich natural grassland, currently dominated by creeping buttercup and meadow foxtail.

収集方法
Malaise traps were deployed four times per year (spring, summer, autumn, winter) from 2019–2023, for two weeks each time, in both the food forest and reference area. The traps targeted flying insects but also collected other arthropods such as spiders and springtails. In addition, nocturnal moths were monitored twice per year (June and August) from 2018–2024 using light traps. Leaf-mining moths were sampled annually in autumn using visual inspection of host plants. Breeding bird surveys were conducted six times each year during the breeding season using standardized territory mapping methods. Sampling locations were selected to be similar in terms of proximity to vegetation structure and water bodies.
| Study Extent | The study was conducted in Food Forest Haarzuilens, a 6-hectare site located near Haarzuilens, west of Utrecht, the Netherlands, and a nearby reference grassland area. Both areas were formerly agricultural grassland and have been managed by Natuurmonumenten since 2007. The food forest was established starting in 2015. Sampling took place from autumn 2019 to summer 2023, with some additional data collected until 2024 (e.g., moths and breeding birds). The two main habitats (food forest and reference grassland) offered contrasting vegetation structures and levels of ecological development, enabling a comparative assessment of biodiversity trends. |
|---|---|
| Quality Control | Insects were sorted and identified under a binocular microscope to the order level, with finer identification (e.g., Diptera split into flies and mosquitoes, Hemiptera into leafhoppers, aphids, and true bugs). Select groups such as leafhoppers, long-legged flies, spiders, and parasitoid wasps were sent to taxonomic specialists for verification. Noteworthy specimens were deposited in expert collections. All traps were checked regularly during each sampling period to ensure trap integrity and fluid levels. Weather conditions were recorded from the nearby meteorological station De Bilt to account for environmental variability in insect activity. |
Method step description:
- Site selection of comparable microhabitats in both the food forest and the reference grassland area. Installation of malaise traps in designated locations near vegetation and water features, sheltered from public access. Traps operated for two weeks each season (spring, summer, autumn, winter) from 2019 to 2023. Trap contents were collected, preserved, and transported to the lab. Insect specimens were sorted and identified; subsets were sent to specialists. Moths were monitored using light traps twice annually (2018–2024); leaf-mining moths were recorded once annually (autumn, 2016–2024). Breeding birds were surveyed using territory mapping (2016–2023). Weather data was collected to contextualize capture variations.
