Anneli Adler
I am a researcher in plant ecology. My research focuses on innovative methods to increase the long-term sustainability of agroecosystems.


One of the methods for increasing the resilience of agroecosystems is to combine species with different growth forms on the same piece of land. This is known as intercropping and aims to increase ecosystem services provided by that area.

Agroforestry with fast-growing trees, as one way of intercropping, has been my main field of research during last years. Fast-growing deciduous trees also have a great potential as complementary raw material for the forest industry to produce textile fiber, bio-oil, packaging etc., and provide additional income for landowners.

Before my return to the university in 2019, I have built up a brand SnowTiger® and worked as manager of a business area in biotecnology company SweTree Technologies AB.




I currently collaborate with Erik Öckinger, Andrew Ruck and René van der Wal within an EU project SHOWCASE. My role in the project is to collect farmers' ideas about sustainable and environmetally friendly agriculture and evaluate an intervention on farmers own fields. Horizon 2020-2024.


In this project I collaborate with prof. Martin Weih and PhD student Joel Jensen. My task is to interview forest owners and managers about their interest to mixed species stands in Swedish forestry.


This project develops a concept for bioeconomy where nutrients in wastewater treatment sludge are recycled in poplar fields to promote the growth of woody raw material. In collaboration with Almir Karacic, Lorenzo Menichetti, Thomas Kätterer, Lina Zickiene and Mindaugas Silininkas we have measured also the accumulation of carbon in soil 30 years after establishment of short rotation forests with poplars, hybrid aspens and silver birch. EU and Swedish Energy Agency finance this project. 2018-2023.

Climate adapted poplars (CLAP)

In cooperation with my collegues Almir Karacic, Ann Christin Rönnberg Wästljung, Giulia Vico, Thomas Richards, Rami-Petteri Apuli, Magnus Herzberg, Pär Ingvarsson and Martin Weih climate adapted poplar clones for Baltic Sea Region have been evaluated and genetic background of spring leaf flush and autumn bud set have been identified. FORMAS 2016-2020.

Cotton substitute and biofuels from fast growing trees by catalytic fractionation

In collaboration with prof. Joseph Samec, Almir Karacic, Gregg Beckham, Rebecca Hanes and their collegues the entire value chain including cultivation of poplar trees, wood processing to man-made cellulose fibers and bio-oil was evaluated in a life cycle perspective. Swedish Energy Agency 2018-2020.
