Changes in forest and agricultural land area in Estonia : [poster]
(Estonian University of Life Sciences, 2024) Jürgenson, Evelin; Järve, Marii; Maasikamäe, Siim; Põdra, Kätlin
Over the course of a century in Estonia, there has been a decrease in agricultural land and increase in forest land. This study gives an overview of hundred years’ worth of land use and ownership changes.
Changing structure of agricultural households in Estonia : [poster]
(Estonian University of Life Sciences, 2024) Järve, Marii; Jürgenson, Evelin
The European agricultural sector is undergoing structural changes, marked by a decrease in farm numbers and an increase in the size of remaining farms Over two decades, Estonia saw an 80% reduction in agricultural households (AH), while average land use (LU) per AH grew. This expansion of large farms has negatively impacted small farms, posing a threat to rural life, food safety, and national security, all of which rely on a high number of small farms and landowners.
An Ecosystem Services Based Approach to Characterising Riparian Forests and Developing Management Solutions
(Estonian University of Life Sciences, 2026) Rebane, Sille; Vodde, Floortje; Jõgiste, Kalev
Riparian forests along river corridors play a important role in sustaining ecosystem services, including water quality regulation, bank stabilization, carbon storage, biodiversity support, and cultural values. Despite their importance, riparian forests are frequently managed using generalized forest typologies that insufficiently reflect their functional roles, spatial heterogeneity, and strong coupling with hydrological processes. The proposed approach is based on the premise that characterising riparian forests solely by site type or stand structure is insufficient for informed decision-making. Instead, riparian forests are described in terms of their capacity to provide ecosystem services, their sensitivity to disturbance, and their relevance for management interventions. Characterisation is structured along key environmental gradients shaping ecosystem service provision, including hydrological connectivity (flood frequency, groundwater interaction), geomorphological position (river bank, floodplain, terrace), vegetation structure and composition, and land-use legacies. Together, these factors determine the ability of riparian forests to regulate nutrient and sediment fluxes, mitigate flood impacts, maintain habitat continuity, and contribute to climate regulation. Building on this characterisation, a multi-dimensional framework is introduced that links biophysical attributes to ecosystem service bundles rather than single functions. This enables the identification of riparian forest types that are particularly important for regulating services (e.g. nutrient retention and erosion control), supporting services (e.g. habitat provision and ecological connectivity), or cultural services (e.g. recreation and landscape values). The framework is designed to inform management by highlighting how different riparian forest types require distinct management solutions, ranging from strict protection and passive restoration to adaptive silviculture that maintains structural complexity while sustaining ecosystem service delivery. The approach is intended to be operational across spatial scales, from individual river reaches to catchment-level planning, and compatible with existing forest inventory, spatial, and hydrological data. By explicitly linking ecosystem service–based characterisation with management options, the framework supports transparent evaluation of trade-offs and synergies among management objectives and helps prioritise areas where riparian forest conservation or restoration delivers the greatest societal benefits.
Forest landscape mosaics: disturbance, restoration and management at times of global change : [international conference], 11-14 August 2014 Tartu, Estonia : book of abstracts

The nature which surrounds us plays a central role in our existence. This is difficult to comprehend, as usually we place ourselves at the center of human existence. If we think of humans as a part of nature, then the environment will be equally important and central (the Estonian word “keskkond” for environment refers to the “center of being”). Ecology has typically focused on pristine systems free from human interference. However, as human influence has become ever more pervasive, there is a growing need for theory to address less than pristine systems. A major question then for ecologists and land managers is the degree of naturalness of a system. Although in the past forestry focused on production of a few commodities, the threat of global environmental change demands that we adopt a new paradigm of forest management that combines past knowledge with innovative management planning strategies that consider a full range of projected ecosystem responses, and resilience to unanticipated factors. It is our great pleasure to host the conference Forest landscape mosaics: disturbance, restoration and management at times of global change, August 11–14, 2014. This meeting brings together scientists, practitioners, policymakers and other experts to share experiences with disturbance management, and evaluate past, present and future application and implementation of research findings from the scientific community. The initiative comes from two working groups of EFINORD/SNS: the network of Natural Disturbance Dynamics Analysis for Forest Ecosystem Management (FORDISMAN) and the Nordic Working Group on the Ecology of Primeval Boreal Forests (PRIFOR). Two major organizations, IUFRO (International Union of Forest Research Organizations) and IAVS (International Association for Vegetation Science) create the main stage for the event. Sponsors supporting the meeting are gratefully acknowledged. The meeting venue is Tartu, second largest city in Estonia and the center of university and science life in this country. The academic atmosphere of this town supports the constructive discussions and research environment needed for people to better understand the relations between humans and nature. The Estonian hemiboreal forest is a unique example of co-existence of people and trees: balanced management and conservation is our planned future. We expect that good colleagues from all around the World will enjoy an interesting program, exciting excursions and social events. Kalev Jõgiste Chairman of the Organizing Committee
The impact of herd health on the efficiency of dairy farms : [presentation]
(Estonian University of Life Sciences, 2020) Põldaru, Reet; Luik-Lindsaar, Helis
Maximization of profit is one of the main interests of any farmer. Profit depends on managerial decisions and many economic factors, but also on the health of the herd. Thus, it is important to study how different factors related to herd health impact farms’ economic performance. The objective of this paper is to determine how herd health influences farm technical efficiency by comparing Estonian farm data from two periods, the years 2012 and 2017. Typically, the major herd health issues are related to udder problems, followed by reproduction issues and limb disorders. We used the FADN (Farm Accounting Data Network) database and data from Estonian Livestock Performance Recording Ltd. The two-stage mathematical approach was chosen as the research method. In the first stage the DEA (Data Envelopment Analysis) was used to estimate farms’ technical efficiency. The output-oriented VRS (Variable Returns to Scale) approach was applied to the data of 64 farms. In the second stage, we used the FRM (Fractional Regression Model) to define which the technical efficiency drivers were among herd health and economic factors. The study revealed that major changes have occurred between the two periods analysed. The main herd health factors influencing farms’ technical efficiency are the somatic cell count (SCC) and age at first calving.

Inoculation success of Inonotus obliquus in birch and alder sites in Estonia
(Estonian University of Life Sciences, 2026) Karin, Kütt; Adamson, Kalev (advisor); Drenkhan, Rein (advisor)
Inonotus obliquus (Ach. ex Pers.) Pilát (commonly known as Chaga) is a medicinal fungus traditionally harvested from birch trees. Artificial cultivation is increasingly considered due to a rising commercial demand. However, our knowledge remains limited regarding infection dynamics and conk development on different host species. We assessed the success of I. obliquus inoculation in Betula pendula, B. pubescens, Alnus incana, and A. glutinosa stands two years after inoculation in order to: (i) identify the most susceptible host tree species and the most effective I. obliquus strains for cultivation; (ii) assess the frequency of conk formation under hemiboreal conditions; (iii) investigate whether visible symptoms on stems resulted from I. obliquus infection; and (iv) determine whether mechanical wounding influenced fungal establishment. The experiment was conducted at two locations in Estonia, encompassing a total of six forest sites, with inoculation success assessed using species-specific qPCR. Sterile conk development was additionally monitored visually four years post-inoculation. Inoculation success differed between the two locations, with an infection rate of 18% observed at Järvselja and 3% at Võrumaa. Three fungal strains consistently achieved higher infection rates among the six tested ones. Conks developed only on A. glutinosa trees and with specific strains. Only the identity of the fungal strains resulted in a significant effect on infection success. Visible stem symptoms, such as bleeding and bulging, were unreliable indicators of the infection rate. Inonotus obliquus conks developed more rapidly on A. glutinosa compared to B. pendula, B. pubescens, and A. incana. Moreover, fungal strains play a crucial role in determining cultivation success.
