Soils and Landscape Restoration provides a multidisciplinary synthesis on the sustainable management and restoration of soils in various landscapes. The book presents applicable knowledge of above- and below-ground interactions and biome specific realizations along with in-depth investigations of particular soil degradation pathways. It focuses on severely degraded soils (e.g., eroded, salinized, mined) as well as the restoration of wetlands, grasslands and forests. The book addresses the need to bring together current perspectives on land degradation and restoration in soil science and restoration ecology to better incorporate soil-based information when restoration plans are formulated.

Let’s go to the forest!
The word “forest” (mets in Estonian) is very old. If you could travel back in time five thousand years and meet one of our Estonian ancestors, they would understand what you mean when you say “mets.”
“Oh-oh-hoo! Mets!” the ancestor would roar with laughter and give you a friendly pat on the shoulder. “Birch, alder, bird cherry—oh-hoo!”
These days, we no longer say “toom” but “toomingas” (the full word for bird cherry tree). Over thousands of years and with the march of technology, many new forest-related words have appeared. Words like “drone” or “pellet” would likely make that ancestor scratch their head in confusion—but you probably understand them.
Researchers at the Estonian University of Life Sciences put their heads together and came up with a whole pile of forest-related words they believe children should know. Then, they divided these words into 32 smaller piles, based on the first letter of each word—32 being the number of letters in the Estonian alphabet. From these piles, I chose a selection of words to introduce to you with the help of forest alphabet stories.
That’s how our Forest Alphabet Book (Metsa-Aabits) was born.
A wise person once said that every book should include at least one story that you don’t understand at all—that’s how you learn. See if you can find such a story in this book!

This collection reviews current research on balancing commercial use with the range of ecosystem services delivered by boreal and temperate forests.
Chapters survey advances in understanding forest ecophysiology, including mechanisms of root and canopy development and the way forest tress react to abiotic stress. The book also discusses current understanding of the ecosystem services that forests deliver and how they can be balanced with activities such as logging. Building on this foundation, it then reviews advances in sustainable forest management techniques, including improvements in breeding, monitoring forest health, innovations in planting, stand management and regeneration as well as harvesting/felling. The book also reviews ways of managing, insect and fungal pests as well as natural hazards. The final section of the book assesses sustainable ways of developing and diversifying forest products, including novel uses of timber, biomass, non-timber products and recreational services.

The relascope and relascope measurement was invented and introduced by Austrian forest scientist Walter Bitterlich (Bitterlich 1947, 1948). The method is widely used because it is simple, handy and quick. However, the method is less accurate when compared to cross-callipering forest measurement. It is used for the preliminary assessment of timber supply in a tree stand 1. Simplified relascope is also called “simple relascope”, “angle-counter”, “angle-gauge” or “angle-template”. S ocalled true relascope or mirror-relascope is a device that can automatically adjust its measured values according to the slope of the ground (photo 1). Electronic relascope can be used instead of traditional mirror-relascope (e.g. Masser RC3, photo 2). Ground slope can be adjusted automatically by inserting slope angle value. Measurement result must be adjusted when using simplified relascope on slopes with angle exceeding 8°. Simplified relascope consists of a chain or non-stretching rope with precise length and rigid slab attached to it. The slab has one or more apertures with precise width (photo 3). It is also possible to create simplified relascope on one’s own, provided that aperture width and chain/ rope length have the greatest precision. Aperture width must remain within tolerance range of 0.1 mm and the length of the chain/rope within the range of 1 mm (Kohava 2002). Instead of a slab, a pen with round crosssection can also be used (photo 4).
