Description

Nature's Calendar (www.naturenskalender.se, in Swedish only) is run by the Swedish National Phenology Network, a consortium of Swedish universities, governmental agencies and NGO:s. The Swedish University of Agricultural Sciences hosts the network. The main task for the Nature's calendar is to collect observations of different spring and autumn signs appearing during the vegetation season.

Data about the nature's calendar is collected in two ways, the long-term environmental monitoring through "Calendars", where phenological observations are reported all through the year, and through "Checks", where phenology observations are reported during short-time campaigns, giving a snapshot of the phenological status at a certain time of the year.

Calendars
The long-term environmental monitoring is performed by citizen scientists and professional observers at research stations and like. Three calendars have been launched in the Nature's Calendar; the Plant's Calendar (from 2008), the Bird's Calendar (from 2016) and the Beekeeper's Calendar (between 2015 and 2018).

Checks
Starting in 2015, a campaign

Dataset 1
Nature´s Calendar - Plant's Calendar

Description

In the Plant's Calendar, Citizen Scientist's have reported observations of how
- budburst and leaf development (broadleaves)
- budburst and shoot elongation (conifers)
- flowering
- ripening of fruits and berries
- seed dispersal
- autumn colors
- leaf shedding
develop during the growing season.

The aim with the data collection is to obtain nationwide data that can provide information to understand, track changes and predict effects of climate change on natural plants in Sweden.

Nature's calendar - Spring Check

Description

In the Spring Check, Citizen Scientist's have reported observations of how far the development of

- budburst of birch
have progressed until Valpurgis Day (some years between April 29 and May 1, some years between April 30 and May 1).

Dataset 3
Nature's calendar - Beekeeper's Calendar

Description

In the Beekeeper's Calendar, Citizen Scientists have reported observations of how
- flowering of plants
- bees and bumblebees flights
- living status of the colony
- supplemental feeding
- angel ball status
- honey production
- tax box additions
- presence of varroa mite
have developed during the growing season.

The aim with the data collection is to obtain nationwide data that can provide information to understand, track changes and predict effects of climate change on beekeeping in Sweden.
