Crash courses on 
August 25 & August 31

1. Crash course: Soil and Water Bioengineering as Nature-Based Solution. An introduction

Organizer(s): Paola Sangalli, EFIB/AEIP; Gianluigi Pirrera, EFIB/AIPIN

Date: 25 August 2024
Time: morning indoors (9:00-13:00), afternoon outside (14:00-16:00)
Location: Oecologicum (Liivi 2, Tartu) and outdoors
Max number of participants: 25
Fee: 50 EUR

Soil and Water Bioengineering is a specific discipline that combines technology and biology in which native plants and plant communities are used as living building material to solve erosion and conservation problems, contributing to the regeneration of degraded ecosystems due to natural or anthropic causes, regenerating dynamics of ecological and geomorphological processes and to the recovery of Biodiversity. It is a nature-based solution with applications in the restoration of wetlands, grasslands, forests, rivers, agroecosystems, and urban and marine ecosystems.

Although these techniques have a huge potential combined with other techniques of ecological restoration, there is still a deficit in knowledge and training.

2. Crash course: Direct Seed Harvest for Ecological Restoration of Grasslands

Organizer(s): Daniel Slodowicz, Ö+L GmbH / HoloSem Switzerland

Date: 31 August 2024
Location: Oecologicum (Liivi 2, Tartu)
Time: 9:00-14:30
Max number of participants: 50
Fee: 30 EUR

Explore the vital process of direct seed harvest for restoring grasslands in this comprehensive course. Covering topics from donor site selection to post-harvest seed processing, participants will gain insights into various harvesting techniques and explore marketing and regulatory aspects. Led by Daniel Slodowicz, a seasoned expert with both scientific and practical experience, this course bridges the gap between science and practice. Ideal for practitioners, researchers, and policymakers involved or interested in grassland restoration by propagules transfer, with botanical knowledge recommended but not mandatory.

3. Crash course: Restoration of transition zones between ecosystems: example of lagg zone / transition zone in bog landscapes. Practical views and information (techniques) needed for planning and assessing results

Organizer(s): Agata Klimkowska, Wetlands International

Date: 31 August & 1 September 2024
Location: Oecologicum (Liivi 2, Tartu)
Time: Starts on the 31.08. at 8:00. Finished by 16:00 on 1.09.
Max number of participants: 19
Fee: 50 EUR

Restoration of wetlands, and peatlands in particular, is challenging and depends on the degree of degradation of the landscapes where the wetlands exist(ed). We focus on transition zones between different types of ecosystems, such as the lagg zones at the edges of bogs, where the gradients of abiotic conditions develop (wet to dry, mineral-poor to mineral-rich, acid to basic, oligotrophic to eutrophic, etc). These zones were the first to be destroyed and no longer exist or function and, in some cases, are not even recognisable any more in the landscapes. These zones are integral parts of peatbogs and often very rich in fauna and flora due to gradients in water levels, acidity, and water mineralisation. The restoration of these zones is important for biodiversity as well as for hydrological functioning of peatland (remnants).

Various types of information and interventions are needed for successful restoration process. We explore the information types needed and innovative information collection techniques (such as geo-radar, mapping the remaining peat depth), applying some of the approaches, and together develop a strategy for the restoration of a transition zone at a case study site not far from Tartu. Throughout the course, we explore different aspects related to the topic: hydrology, ecological processes and indicators, types and implementation of restoration interventions, engagement with the public, and involvement with local communities.  

Our focus extends to transition zones in peatbogs, recognising that adequate attention is crucial to addressing various restoration challenges appropriately. Other examples of such zones include transition along water salinity gradient (coastal marshes), transition along a sediment gradient from clay to sand (coastal marshes), transition along the groundwater seepage quality (deep vs. shallow groundwater), etc.
