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 am/have been teaching on the following courses:

  • Lantbruksvetenskap för mark/växtagronomer (15 HP), course leader Dr. Ida Kollberg
  • Agroforestry (15 HP), course leader Doc. Linda-Maria Dmitrova
  • Production of non-food biomass 2022 (3 ECTS credits) – course leader Doc. Ioannis Dimitriou
  • Experimental approaches in plant growth analysis and phenotyping (15 HP), 2022, course leader Prof. Martin Weih, SLU
  • ELLS Summer School Bioeconomy (6 ECTS credits), July 31st – August 11th 2023 Uppsala; SLU, course leader Prof. Martin Weih, SLU



In cooperation with farmers around lake Mälaren our project group (Erik Öckinger as project leader, Andy Ruck, René van der Wal and John Löfkvist), evaluates the effect of mixed cropping on biodiversity at farmers own fields and surrounding landscapes. EU Horizon 2020-2024.


In this project I collaborate with prof. Martin Weih and PhD students Joel Jensen and Leticia Bulascoschi Cagnoni. My task is to interview forest owners and managers about their interest to establish and manage mixed species stands on forestland in Sweden.


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 from SweTree Technologies AB, Prof. Pär Ingvarsson and Prof. 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. Business plan for marketing poplar clones bred at SLU for commercial use, #SnowTiger, has been developed. FORMAS 2016-2020.

Cotton substitute and biofuels from fast growing trees by catalytic fractionation

In collaboration with prof. Joseph Samec's research group, 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.

Vegetation dynamics on wooded meadows 

In collaboration with Prof. Kalevi Kull and Dr Marek Sammul, I have been investigating the plant community dynamics of wooded meadows during the cessation of active management of these species rich ecosystems.
