You can examine the current state, future, and structure of an old, unmanaged forest stand from the graphs on the board, as well as by walking to the site.<\/p><p><strong>The importance of deadwood for forest species.<\/strong> Old-growth forests are rich in species. This is partly explained by the abundance of dead trees. A quarter of Finnish species and nearly half of endangered species are dependent on deadwood. Efforts are being made to increase deadwood in commercial forests through retention trees and artificial snags. Detour along the path to an old-growth forest, which is close to its natural state. You can get more information about the connection between deadwood and biodiversity through an animation.<\/p><p><strong>Multi-objective silviculture.<\/strong> Finland's diverse and abundant forest resources are the basis for the sustainable utilization of forests. With changes in the operating environment of the forest sector, the objectives for forest management are diversifying, and options are increasing. Forests produce wood for industrial raw materials, sequester and store carbon, and provide habitats for species and recreational opportunities for people. More information can be found on the site's boards and in the observation area behind the boards.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-660d485 elementor-widget-divider--separator-type-pattern elementor-widget-divider--no-spacing elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"660d485\" data-element_type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-divider\" style=\"--divider-pattern-url: url(&quot;data:image\/svg+xml,%3Csvg xmlns=&#039;http:\/\/www.w3.org\/2000\/svg&#039; preserveAspectRatio=&#039;xMidYMid meet&#039; overflow=&#039;visible&#039; height=&#039;100%&#039; viewBox=&#039;0 0 123 26&#039; fill=&#039;black&#039; stroke=&#039;none&#039;%3E%3Cpath d=&#039;M6.4,2l4.2,5.7H7.7v2.7l3.8,5.2l-3.8,0v7.8H4.8v-7.8H0l4.8-5.2V7.7H1.1L6.4,2z M25.6,2L31,7.7h-3.7v2.7l4.8,5.2h-4.8v7.8h-2.8v-7.8l-3.8,0l3.8-5.2V7.7h-2.9L25.6,2z M47.5,2l4.2,5.7h-3.3v2.7l3.8,5.2l-3.8,0l0.4,7.8h-2.8v-7.8H41l4.8-5.2V7.7h-3.7L47.5,2z M66.2,2l5.4,5.7h-3.7v2.7l4.8,5.2h-4.8v7.8H65v-7.8l-3.8,0l3.8-5.2V7.7h-2.9L66.2,2zM87.4,2l4.8,5.7h-2.9v3.1l3.8,4.8l-3.8,0v7.8h-2.8v-7.8h-4.8l4.8-4.8V7.7h-3.7L87.4,2z M107.3,2l5.4,5.7h-3.7v2.7l4.8,5.2h-4.8v7.8H106v-7.8l-3.8,0l3.8-5.2V7.7h-2.9L107.3,2z&#039;\/%3E%3C\/svg%3E&quot;);\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"wd-negative-gap elementor-element elementor-element-6e2759d e-flex e-con-boxed e-con e-parent\" data-id=\"6e2759d\" data-element_type=\"container\" id=\"hiilen-varastot-metsissa\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-b309147 elementor-widget elementor-widget-heading\" data-id=\"b309147\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Carbon stocks in forests<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6c067c1 elementor-widget elementor-widget-heading\" data-id=\"6c067c1\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">The capacity of forests to sequester and store carbon varies according to the forest's development stage<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-258f1df elementor-widget elementor-widget-wd_text_block\" data-id=\"258f1df\" data-element_type=\"widget\" data-widget_type=\"wd_text_block.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"wd-text-block reset-last-child text-left\">\n\t\t\t\n\t\t\t<p>Carbon sequestration (carbon sink) is strongest in well-managed and fast-growing youngforests.\nCarbon has mostly been stored in mature forests, where growth has already slowed down.\nIn Finland, about 3 300 million tonnes of CO\u2082 eq. have been sequestered in tree biomass.\nIn Finland, soil carbon storage is estimated to be around 14 000 million tonnes of CO\u2082 eq.

Emissions are usually expressed in carbon dioxide equivalents CO2 eq. for example through soil respiration.<\/p><p>Emissions are generated during industrial processes, heating of buildings, transport, agriculture and waste processing.<\/p><p>Forests also release carbon dioxide into the atmosphere, for example through logging and natural thinning.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a5ecf77 elementor-widget-divider--separator-type-pattern elementor-widget-divider--no-spacing elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"a5ecf77\" data-element_type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-divider\" style=\"--divider-pattern-url: url(&quot;data:image\/svg+xml,%3Csvg xmlns=&#039;http:\/\/www.w3.org\/2000\/svg&#039; preserveAspectRatio=&#039;xMidYMid meet&#039; overflow=&#039;visible&#039; height=&#039;100%&#039; viewBox=&#039;0 0 123 26&#039; fill=&#039;black&#039; stroke=&#039;none&#039;%3E%3Cpath d=&#039;M6.4,2l4.2,5.7H7.7v2.7l3.8,5.2l-3.8,0v7.8H4.8v-7.8H0l4.8-5.2V7.7H1.1L6.4,2z M25.6,2L31,7.7h-3.7v2.7l4.8,5.2h-4.8v7.8h-2.8v-7.8l-3.8,0l3.8-5.2V7.7h-2.9L25.6,2z M47.5,2l4.2,5.7h-3.3v2.7l3.8,5.2l-3.8,0l0.4,7.8h-2.8v-7.8H41l4.8-5.2V7.7h-3.7L47.5,2z M66.2,2l5.4,5.7h-3.7v2.7l4.8,5.2h-4.8v7.8H65v-7.8l-3.8,0l3.8-5.2V7.7h-2.9L66.2,2zM87.4,2l4.8,5.7h-2.9v3.1l3.8,4.8l-3.8,0v7.8h-2.8v-7.8h-4.8l4.8-4.8V7.7h-3.7L87.4,2z M107.3,2l5.4,5.7h-3.7v2.7l4.8,5.2h-4.8v7.8H106v-7.8l-3.8,0l3.8-5.2V7.7h-2.9L107.3,2z&#039;\/%3E%3C\/svg%3E&quot;);\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"wd-negative-gap elementor-element elementor-element-7811595 e-flex e-con-boxed e-con e-parent\" data-id=\"7811595\" data-element_type=\"container\" id=\"monimuotoisuus-metsissamme\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-f4d2b6b elementor-widget elementor-widget-heading\" data-id=\"f4d2b6b\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Biodiversity in our forests<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d441e17 elementor-widget elementor-widget-wd_text_block\" data-id=\"d441e17\" data-element_type=\"widget\" data-widget_type=\"wd_text_block.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"wd-text-block reset-last-child text-left\">\n\t\t\t\n\t\t\t<p>Biodiversity, also known as biological diversity or the variety of life, refers to the biological variation in nature, such as the abundance of species, genetic variation within species, and the diversity of habitats. Biodiversity is a prerequisite for the ecosystem services provided by nature and for nature's ability to adapt to environmental changes. Clean water and air, pollination, and the availability of raw materials and nutrients are linked to biodiversity.<\/p><p>Approximately 50,000 species live in Finland, over 20,000 of which are in forests. Forest species are influenced by, among other things, the forest's developmental stage, forest type, and climatic conditions, but also by human activity.<\/p><p><strong>Species endangerment in Finland.<\/strong> In Finland, one in nine species is endangered. About a third of these (833 species) primarily live in forests. Forest management and, increasingly, climate change have contributed to the endangerment of forest species. Efforts have been made to address endangerment and the decline of biodiversity through regulation and new operating methods, and for some species, the situation has improved.<\/p><p><strong>How can the loss of biodiversity be stopped?<\/strong> In forests, species endangerment can be influenced by improving habitats through nature management, such as controlled forest fires, preventing spruce encroachment, and restoring habitats. Additionally, the amount of deadwood can be increased, and forest management methods that mimic natural development, such as uneven-aged forest management, can be used. A comprehensive network of protected areas is also an effective way to secure species' habitats.<\/p><p><strong>The importance of deadwood for forest species.<\/strong> Old-growth forests are rich in species. This is partly explained by the abundance of dead trees. A quarter of Finnish species and almost half of endangered species are dependent on deadwood. Efforts are being made to increase deadwood in commercial forests through retention trees and artificial snags. Detour along the path to the biodiversity site, which is close to its natural state. You can also get more information about the connection between deadwood and biodiversity through an animation.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-488fb25 elementor-widget elementor-widget-wd_button\" data-id=\"488fb25\" data-element_type=\"widget\" data-widget_type=\"wd_button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"wd-button-wrapper text-left\" >\n\t\t\t<a class=\"btn btn-style-link btn-style- btn-size-default btn-color-alt btn-icon-pos-right\"  href=\"https:\/\/www.luke.fi\/fi\/uutiset\/talousmetsilla-on-ratkaiseva-rooli-metsalajiston-turvaamisessa\" target=\"_blank\">\n\t\t\t\t<span class=\"wd-btn-text\" data-elementor-setting-key=\"text\">\n\t\t\t\t\tCommercial forests and biodiversity\t\t\t\t<\/span>\n\n\t\t\t\t\t\t\t\t\t<span class=\"wd-btn-icon\">\n\t\t\t\t\t\t<svg class=\"wd-icon e-font-icon-svg e-fas-external-link-alt\" viewbox=\"0 0 512 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M432,320H400a16,16,0,0,0-16,16V448H64V128H208a16,16,0,0,0,16-16V80a16,16,0,0,0-16-16H48A48,48,0,0,0,0,112V464a48,48,0,0,0,48,48H400a48,48,0,0,0,48-48V336A16,16,0,0,0,432,320ZM488,0h-128c-21.37,0-32.05,25.91-17,41l35.73,35.73L135,320.37a24,24,0,0,0,0,34L157.67,377a24,24,0,0,0,34,0L435.28,133.32,471,169c15,15,41,4.5,41-17V24A24,24,0,0,0,488,0Z\"><\/path><\/svg>\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t<\/a>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4c3cc47 elementor-widget-divider--separator-type-pattern elementor-widget-divider--no-spacing elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"4c3cc47\" data-element_type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-divider\" style=\"--divider-pattern-url: url(&quot;data:image\/svg+xml,%3Csvg xmlns=&#039;http:\/\/www.w3.org\/2000\/svg&#039;

Growth must be increased when aiming to maintain current timber production levels and enhance carbon sequestration. Growth and carbon sequestration can be increased by:<\/p><ul><li>genetically improved seed and seedling material<\/li><li>rapid regeneration<\/li><li>selecting tree species suitable for the site<\/li><li>timely seedling stand management<\/li><li>fertilization<\/li><li>growing larger diameter trees<\/li><\/ul><p>Ensuring forest growth and vitality requires tree species and forest management methods suitable for the site. Silvicultural thinnings direct growth to well-growing trees. However, overly strong thinnings, especially in pine stands, should be avoided.<br \/>The adaptability of forests to changing conditions can be increased by diversifying forest management and tree species composition, increasing the proportion of deciduous trees, enhancing biodiversity, and using adaptable planting material. In high-risk areas, avoiding damage risks and repairing damage are essential in forest management.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-be83e67 elementor-widget-divider--separator-type-pattern elementor-widget-divider--no-spacing elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"be83e67\" data-element_type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-divider\" style=\"--divider-pattern-url: url(&quot;data:image\/svg+xml,%3Csvg xmlns=&#039;http:\/\/www.w3.org\/2000\/svg&#039; preserveAspectRatio=&#039;xMidYMid meet&#039; overflow=&#039;visible&#039; height=&#039;100%&#039; viewBox=&#039;0 0 123 26&#039; fill=&#039;black&#039; stroke=&#039;none&#039;%3E%3Cpath d=&#039;M6.4,2l4.2,5.7H7.7v2.7l3.8,5.2l-3.8,0v7.8H4.8v-7.8H0l4.8-5.2V7.7H1.1L6.4,2z M25.6,2L31,7.7h-3.7v2.7l4.8,5.2h-4.8v7.8h-2.8v-7.8l-3.8,0l3.8-5.2V7.7h-2.9L25.6,2z M47.5,2l4.2,5.7h-3.3v2.7l3.8,5.2l-3.8,0l0.4,7.8h-2.8v-7.8H41l4.8-5.2V7.7h-3.7L47.5,2z M66.2,2l5.4,5.7h-3.7v2.7l4.8,5.2h-4.8v7.8H65v-7.8l-3.8,0l3.8-5.2V7.7h-2.9L66.2,2zM87.4,2l4.8,5.7h-2.9v3.1l3.8,4.8l-3.8,0v7.8h-2.8v-7.8h-4.8l4.8-4.8V7.7h-3.7L87.4,2z M107.3,2l5.4,5.7h-3.7v2.7l4.8,5.2h-4.8v7.8H106v-7.8l-3.8,0l3.8-5.2V7.7h-2.9L107.3,2z&#039;\/%3E%3C\/svg%3E&quot;);\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"wd-negative-gap elementor-element elementor-element-1450905 e-flex e-con-boxed e-con e-parent\" data-id=\"1450905\" data-element_type=\"container\" id=\"etrs89\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"wd-negative-gap elementor-element elementor-element-de7af03 e-flex e-con-boxed e-con e-child\" data-id=\"de7af03\" data-element_type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-2b044fc elementor-widget elementor-widget-heading\" data-id=\"2b044fc\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Site information<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c1c6486 elementor-widget elementor-widget-wd_text_block\" data-id=\"c1c6486\" data-element_type=\"widget\" data-widget_type=\"wd_text_block.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"wd-text-block reset-last-child text-left\">\n\t\t\t\n\t\t\t<p>ETRS89<br \/>61\u00b0 48\u2019 50\u201dN and 29\u00b0 19\u2019 43\u201dE<br \/>Altitude above sea level 82.5 m<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8edf82c elementor-widget elementor-widget-wd_text_block\" data-id=\"8edf82c\" data-element_type=\"widget\" data-widget_type=\"wd_text_block.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"wd-text-block reset-last-child text-left\">\n\t\t\t\n\t\t\t<p>This stand on a Vaccinium myrtillus type heath forest (MT) was established in 1898 by sowing Scots pine and Norway spruce seeds on slash-and-burn land (kaski).
