Enriching Agricultural Landscapes with Hedges and Shrub Strips

Estonia

Mixed Forest Sub-region of the Atlantic Continental region of the Temperate zone

Benefits of the Practice


  1. Diverse Habitats: Supports various species, boosting biodiversity.

  2. Enhanced Forage Base: Provides food for birds, animals, and insects, promoting pollination.

  3. Natural Pest Management: Encourages ecological balance, reducing pests.

  4. Carbon Storage: Increases carbon sequestration, mitigating climate change.

  5. Microclimate Stability: Regulates temperature and moisture levels.

  6. Wind Protection & Erosion Control: Shields crops, birds, and wildlife.

  7. Aesthetic Value: Creates visually appealing agricultural landscape

Thematic Areas

Production System/s

Biodiversity and climate friendly plant production

Summary for Practicioners on the Main Finding(s)/Innovative solution(s)

The University of Tartu is collaborating with farmers to enrich agricultural landscapes by planting diverse hedgerows. As part of the Climate Farm Demo project, OÜ Mäemõisa established the first trial, planting a 130-meter hedgerow with various trees and shrubs suitable for hedging, including buckthorn, viburnum, blackcurrant, gooseberry, hawthorn, hazel, and elm. Over the next few years, they plan to establish approximately 4 kilometers of hedgerows.
For the first trial, they focused mainly on native plants, some bearing edible fruits. In subsequent stages, they will create different types of hedgerows and tree lines—some designed for harvestable fruits, others to support biodiversity, and some for aesthetic appeal.
The planting area also includes experiments with different mulches and trunk protection methods. One key reason for establishing hedgerows was to create green corridors that connect forest masses separated by fields. The project also includes observations on planting tools and techniques, offering insights for both the farmers and other hedgerow enthusiasts.
Researchers recommend establishing both pruned and free-form hedgerows. The location choice should consider local conditions, expectations, and possibilities. Hedgerows with a mix of species, including natural ones from the surrounding area, are more likely to survive. It is advised to select species of different heights, with flowering and fruiting occurring at different times.
In areas where maintaining herbaceous vegetation is difficult, wider strips are recommended. Hedgerows and shrub strips are best established in early spring or autumn. Taller shrubs should be grouped toward the center, while smaller shrubs should be placed around them.
During the first few years, hedgerows require more care, including mulching. A 6-meter mown grass strip around the hedgerows is recommended, which can also be seeded with natural seed mixes to support biodiversity.

Summary for Practicioners in Native Language

Tartu Ülikool katsetab koos talunikega põllumajandusmaastike rikastamist liigirikaste hekkidega. Climate Farm Demo projektis osalev OÜ Mäemõisa rajas oma põllule esimese katsena 130-meetrise, mitmesugustest hekitaimedeks sobivatest puudest ja põõsastest koosneva heki (türnpuu, lodjapuu, magesõstar, mustsõstar, tikker, viirpuu, sarapuu, jalakas jmt). Järgnevatel aastatel on plaan rajada umbes 4 kilomeetrit erinevaid elurikkaid hekke. Esimese katseriba hekitaimede valikul sooviti lisada eelkõige kodumaiseid taimi, millest osad on ka söödavate viljadega. Järgmistes etappides luuakse eriilmelisi hekke/puuderibasid, milledest mõnede eesmärk on pakkuda ka saagiks sobivaid vilju, teised keskenduvad rohkem elurikkuse toetamisele ning mõnede puhul on oluline ka esteetiline mulje.
Hekitaimede istutusalal katsetati erinevaid multše ja tüvekaitsemeetodeid. Tootja üheks hekkide rajamise põhjuseks oli soov luua rohekoridore, mis ühendaksid metsamassiive, mida eraldavad mitmed põllud. Heki osas tehakse projektis tähelepanekuid erinevate istutusvahendite ning -protsessi kohta, mis omakorda võiks aidata järgmiste hekkide istutamise puhul nii tootjaid endid kui ka teisi hekihuvilisi. Teadlased soovitavad rajada nii pügamist vajavaid kui ka vabakujulisi hekke.

Asukoha valikul tuleks kindlasti arvestada kohalike olude, ootuste ja võimalustega. Mitmeliigilistel ja ümbruskonna looduslikest liikidest koosnevatel hekkidel on kahjustajaid vähem. Istutamiseks on hea valida erineva kõrgusega, aga ka erinevatel aegadel õitsevaid ja viljuvaid liike. Nutikas on rajada ka kohati laiemaid ribasid kohtadesse, kus on rohttaimestiku hooldus raskendatud. Hekid või põõsasribad rajatakse üldjuhul varakevadel või sügisel. Kõrgema kasvuga põõsad võiks paigutada väiksemate rühmadena põõsasriba keskele, väikesekasvulisemad suuremate rühmadena riba servadesse. Esimestel aastatel vajavad põõsasribad ja hekid rohkem hoolt, sh ka multšimist. Hekkide ja põõsasribade ümber peaks olema niidetav rohumaariba, millesse võib külvata looduslikke seemnesegusid.
