Kidnapped trees, Tree Pages, Outdoor Environment No. 8, 2024

Description: It is great that the benefits of trees are becoming widely known and spreading beyond our guild. At the same time, there is a risk that other stakeholders, who only have one of the values of trees in focus, drive development in the wrong direction. Those of us who work with trees on a daily basis should therefore guard the interests of trees to ensure that they are not reduced to a mere tool used to achieve a specific goal.

Two thoughts in your head, at the same time, Tree Pages, Outdoor Environment No. 7, 2024

Description: Most conversations about trees today focus on one of two key aspects: biodiversity or climate change adaptation. But focusing on only one of these risks leading to poorly thought-out decisions, which in the long run can cause us to miss important values. To value trees sustainably, we need to learn to hold two thoughts in our heads, simultaneously.

The return of the bare-rooted trees, Tree Pages, Outdoor Environment No. 6, 2024

Description: Today, the majority of trees in the public realm are planted as clump-digging trees, which means that they dug up from the nursery with a root ball containing the soil or clay that the tree has grown in. The root ball is then wrapped in jute fabric and then in a steel basket to keep it intact during transportation. This has become the dominant method of planting trees, but it has not always been so. Just a few decades ago, bare-root trees, i.e. trees that were harvested in the nursery by shaking the soil off the roots, were the norm.

Treekollen, Tree Pages, Outdoor Environment No. 5, 2024

Description: Too many trees are unnecessarily damaged during construction and excavation work. At the same time, we have learned a long time ago to always ask for a line check before we start digging. The same should should apply to trees, and if we all carry out a tree check before putting the digger in the ground many more trees will be able to grow big and old and provide the important ecosystem services that only particularly large trees can. In return, we will have safer and more efficient construction processes.

Tree advice, Tree pages, Outdoor environment no 4 2024

Description: Many times trees are cut down unnecessarily due to decisions made by uninformed people influenced by individuals from the public. By establishing tree councils, organizations can make more informed decisions about whether or not to cut trees while working towards more strategic and sustainable tree management.

Substrate and soil, Tree pages, Outdoor environment no. 3 2024

Description: The fact that we can now build plant beds that can handle heavy traffic and at the same time be large and functional enough to house large trees is fantastic. But the craze for skeletal soils must not lead us to forget the knowledge of ordinary soils in a natural profile. After all, the vast majority of trees are still planted in some form of parkland.

Municipal nurseries, Tree Pages, Outdoor Environment No. 2 2024

Description: In addition to traditional nurseries, a municipal nursery can produce small series of unusual species and make use of crooked and twisted individuals. There are also some climate benefits in the form of shorter transportation distances and delivery of plants in sync with the season.

Conifers, green gold in winter, Tree Pages, Outdoor Environment No. 1 2024

Description: Winter is something that we in this country have to deal with, whether we like it or not. As a gardening enthusiast with a love of greenery, spending between four and six months (yes, that's how long it is) in a largely defoliated landscape can sometimes be quite painful. In our northern parts of the country, snow helps to brighten things up, which can mitigate the lack of chlorophyll somewhat. But in our southern parts, winter tends to become less and less white, and more and more gray-brown. As a cure for this deficiency disease, a visit to the nearest evergreen park is recommended. Since there are not many evergreen deciduous trees for the Swedish climate, it is mainly the evergreen conifers that will become our conifers that become our medicine. Even though we mostly use deciduous trees in parks and other outdoor environments, it is therefore important that we plant evergreens in between. In this text I have therefore chosen to highlight five nice conifers that should be used more often.

Crown cover, so what? Tree gap, Outdoor Environment No. 7, 2023

Description: Only a few years ago, crown coverage was a new concept that many people did not know. Today, the calculated crown coverage is publicly available for many of our cities, not least thanks to the Swedish National Board of Housing, Building and Planning's recent publication of the crown coverage for over 200 urban areas around Sweden. Although not all cities are included in the Swedish National Board of Housing, Building and Planning's analysis, there are other options through Husqvarna's Hugsy, the i-Tree Canopy tool or actually ordering a crown coverage analysis from a consulting firm. However, with more and more municipalities' crown coverage mapped, the question remains, what should we use the information for?

Sustainable plant choices, Tree gap, Outdoor environment no 6, 2023

Description: How do we really define sustainability when it comes to plant selection? In this edition of the tree column, we take a closer look at how we can avoid wasting resources and instead, through a quality assured plant selection process, achieve success in all plantings.

Technology leap in organic bransh, Tree gap, Outdoor environment no 5, 2023

Description: New technologies abound for managers and consultants working with urban trees. Automated surveying, satellite analysis, connected moisture meters and image analysis are just a few examples. As technology accelerates, we need to ask ourselves how we can best use it. And it is important that we stop and ask ourselves how to use all the new data.

Who owns the trees? Tree column, Outdoor Environment No 4, 2023

Description: When trees are cut down, it can upset the feelings of those who were not involved in the decision. And sometimes, even afterwards, it can turn out to be a wrong decision. Even if the decision to cut down a tree is correct, there are good reasons to provide information about why the tree is being cut down. Respecting that tree ownership is complicated, and that the mere sight of a tree can mean a lot to a person, we can avoid conflict and comfort emotions.

Schoolyard trees - vital but forgotten? Tree column, Utemiljö nr 3, 2023

Description: The importance of trees to our well-being is a connection that probably comes naturally to most people. New efforts are being made to make cities greener. For example, the 3-30-300 rule is an objective that many that many municipalities are working towards, which means, among other things, that from each home, school and workplace should be able to see three trees. Yet today we still find plenty of examples where development is at a standstill, or even going backwards, when it comes to bringing in more trees in urban schoolyards.

What is a climate-smart tree, Tree column, Utemiljö nr 2, 2023

Description: When we plant a tree, I hope that most of us anticipate that the tree will live for at least 50-100 years. at least 50-100 years, anything else would be a waste of resources. We often choose species with great care in terms of aesthetics and contemporary hardiness. But what we often forget to ask ourselves is, what climate will be prevail on the site in 100 years? We should therefore ask ourselves which species are best suited to the are equipped for future climate, future weather and future ecosystem service needs. The trees that qualify through this tough thinning process can be called climate-smart trees.

How do we maximize the stormwater management of trees?, Tree column, Utemiljö nr 1, 2023

Description: That our cities are at greater risk of flooding as a result of climate change is no longer news. is no longer news. We need to use all the means at our disposal to improve stormwater management and thus reduce the risk of flooding. Common measures include submerged activity areas, open stormwater systems and underground storage. What these measures have in common is that they require extensive redevelopment and and resources to be implemented.

Tree diversity, but how much?, Tree column, Utemiljö nr 8, 2022

Description: We have probably all heard that tree stands should have a good diversity. There are many reasons for this, e.g. to spread the risks of disease attacks, to create experience values for citizens or increasing the number of food sources and habitats for animals and insects. But the question is what defines good species diversity?

Good alternative to Rosaceae, Tree Gap, Outdoor Environment No. 7, 2022

Description: The challenges of poor species distribution in our urban environments are by now well known. Despite our knowledge about this, many areas are still planted with an almost monoculture of trees belonging to the Rosaceae family. To reduce the risks associated with of overuse, and to enhance the aesthetic qualities, this column highlights a number of examples of of trees that are suitable to complement our otherwise overused rose relatives.

Plan for more neighborhood forests, Tree column, Utemiljö nr 6, 2022

Description: By planting a large number of small tree seedlings densely together with shrubs and perennials we can quickly create natural environments in small areas of the city. Through the concept of a neighborhood forest, we want to introduce your readers to a new way of planning for nature in previously unused spaces, while at the same time engage and educate citizens.

We need big trees, Tree column, Utemiljö nr 5, 2022

Description: While we know that larger trees provide more ecosystem services, many trees are still being planted many trees are still planted with a very small final size. The reason may be a desire to reduce maintenance or fear of conflict with building facades or other infrastructure. However, the fact remains that a small tree can never compete with a large one in terms of delivering important ecosystem services.

The uncertain future of climbing trees, Tree column, Utemiljö nr 4, 2022

Description: I'm sure many of us remember the climbing tree of our childhood in detail. The tree that was just your own and that not even your best friend knew about. Which foot you had to put up first against the trunk first against the trunk to get up and how the bark felt rough against the palm of your hand. Humans have always been able to climb trees, but are future generations about to miss out on the missing out on the lessons learned from climbing trees as children?
