[ID: 283] Hälsingfors catchment

PI: Mats Nilsson

Monitoring of several catchments at Hälsingfors


[ID: 253] Reference climate monitoring at the Experimental Forests

PI: Ola Langvall

Reference climate monitoring takes place at all experimental forests (only during the summer in Ätnarova). It got its common design in 1989 and started routinely in January 1990. The basic measurement comprise air and ground temperatures, humidity, global radiation and precipitation. Measurement data is automatically processed for forestry applications. Climate data from the reference stations is stored and available at the respective experimental park and at Vindelns experimental parks.

[ID: 237] Lake chamber flux measurements

PI: Hjalmar Laudon

Floating chambers are used to determe Green House Gas emissions from lake Stortjärn. The sampling strategy is based on the lake depth structure and three transects with 1 to 4 chambers each located so that they cover the majority of the depth profile.

[ID: 236] Stortjärn lake water sampling

PI: Hjalmar Laudon

Lake Stortjärn is one of the most expansive research sites within the Krycklan catchment, both in terms of new projects and infrastructure development.


[ID: 235] Snowcat groundwater monitoring

PI: Hjalmar Laudon

In total, close to 20 wells are installed spanning from 5 m to over 150 m depth. The installations were made to cover the entire Krycklan catchment to investigate regional groundwater as well as allow more local studies of water pathways. The first wells were installed by the Swedish Geological Survey (SGU) in the 1980s and have been monitored since, whereas the majority was installed in 2012.


[ID: 234] Russian wells groundwater monitoring

PI: Hjalmar Laudon

The Kallkäls-mire is the source area for stream C4, and the location of the “Russian wells”. These wells are a set of piezometers allowing sampling at different depths in, and below the mire.


[ID: 233] S-transect groundwater monitoring

PI: Hjalmar Laudon

The S-transect was installed 1997 and has been sampled monthly since. The transect consists of ceramic suction lysimeters at 5-7 depths in three plots: the riparian zone 4 m from the stream (S04), 12 m from the stream (S12) and in the up-slope mineral soil 22 m from the stream (S22). The installations are made so that samples can be collected all year by using a heating cable where the water passes through the frozen soil. The hydrology is focused in the upper horizons due to the hydrological conductivity which increases exponentially towards the soil surface.


[ID: 231] Precipitation collection

PI: Hjalmar Laudon

Water collected and analysed after each precipitation event


[ID: 230] Snow profile

PI: Hjalmar Laudon

Sampling of snow transects with bulked samples analysed for chemistry.


[ID: 224] Monitoring Gusseltjärnsdammen Siljansfors

PI: Ola Langvall

Ett avrinningsområde inom Siljansfors försökspark, innefattande Gusseltjärnen, har övervakats med flödesmätningar och kemiska vattenprovtagningar sedan 198?. Övervakningen initierades av Lars Lundin, SLU, Inst. för vatten och miljö, Uppsala. Numera görs övervakningen i försöksparkens egna regi. Vattenflödet mäts i Gusseltjärnsdammen med automatisk mätutrustning, medan vattenprover tas månadsvis, för kemiska analyser. A small watershed within Siljansfors Experimental Forest has been monitored since 198?. The monitoring was initiated by Lars Lundin at SLU, Dept. of water and environment in Uppsala. Nowadays the monitoring is run by the Experimental Forest. Water flow is monitored by automatic measurements and water samples for chemical analysis are taken monthly.


[ID: 222] Phenology monitoring at the Experimental Forests

PI: Ola Langvall

Phenology is monitored at the four Experimental Forests that are staffed. General plant phenology is monitored weekly in the concept of Natures Calendar ( This monitoring has been ongoing since 2008, as part of the collaboration within the Swedish National Phenology Network (SWE-NPN). Intensive forest phenology is monitored weekly during the growing season on birch, spruce and pine trees, including measurements of bud and leaf/shoot lengths, and also the abundance of flowers, unripe and ripe berries on bilberry and lingon-berry plants. This monitoring has been ongoing since 2006.


[ID: 123] Long term monitoring of Ips typographus

PI: Mats Jonsell

Using pheromone traps and survey of killed spruce trees the long term changes are described and are used as a decision tool for forest management against the spruce bark beetle. Data are also used for scientific purpose, analyzing time series.
