Biodiversity and local features of 103 public urban squares in Munich, Germany

This dataset contains biodiversity and square features of 103 public urban squares (Platz in German) in Munich, Germany. Data were collected to investigate how designed features of urban squares influences the biodiversity occurring there. Data were collected between April 2017 and July 2020. Square features were characterised using Colour-infrared Aerial images (CIR, Bavarian Agency for Digitisation, High-Speed Internet and Surveying, Munich) and land register maps and measurements using a telemeter and a tape measure. Biodiversity of arthropods, bats, birds, bryophytes, pollinators, small mammals, and spontaneous vegetation was determined using taxa-specific sampling methods and deriving richness and abundance (or activity) for each taxon.
 , Arthropods were sampled using suction sampling for sealed surfaces, grass, and flowerbeds. Trees and shrubs were sampled using knockdown sampling. Sampled arthropods were collected in jars and sorted to order level in the laboratory.
Bats were sampled using an ecoObs Batcorder 3.1 ultrasonic recorder (quality = 20, threshold = -36 dB, post-trigger = 800 ms, critical frequency = 14kHz). Recording took place from one hour before sunset to one hour post sunrise four times on single nights. Bat calls were identified to species level where possible and where not, the lowest level species group was attributed based on the acoustic properties.
Birds (separately considering the feral pigeon, Columba livia domestica) were determined visually and aurally by observing all birds within a 25m radius along transects for a total of 20 minutes on each square in spring, fall, and winter.
Bryophytes (including mosses and liverworts) was determined by collecting bryophytes on three different types (wood, ..., , # Data from: Biodiversity and local features of 103 public urban squares in Munich, Germany
