Modeling urban distributions of host trees for invasive forest insects in the eastern and central USA: A three-step approach using field inventory data

Despite serving as invasion gateways for non-native forest pests, urban forests are less well understood than natural forests. For example, only a fraction of communities in the USA and Canada have completed urban forest inventories, and most have been limited to street trees; sample-based inventories that provide valid communitywide estimates of urban forest composition are much rarer. As a proof...

Invasive plants can boost blue carbon storage

When invasive species enter the picture, things are rarely black and white. A new article has revealed that some plant invaders could help fight climate change by making it easier for ecosystems to store 'blue carbon' -- the carbon stored in coastal environments like salt marshes, mangroves and seagrasses. But other invaders, most notably animals, can do the exact opposite....

Greenpeace Russia has produced a map of stand replacement return intervals in the world’s northern forests (north of 40 ? northern latitude), which helps to evaluate whether recent forest management (at the scale of one hundred thousand ha*) may lead to forest depletion, also taking into account actual forest losses due to natural or semi-natural stand-replacement events. The map was first rele...

Greenpeace Russia suggestions on protection of intact forest landscapes to the developers of the new Russian national FSC standard

Currently FSC in Russia, as well as FSC in many other countries, is developing new national standard. The changes in the standard are expected to take into account decisions made at the FSC General Assembly in 2014 (incl. demands on protection of intact forest landscapes, stated within the Motion 65). Greenpeace Russia is no longer a member of FSC and does not directly participate in the standard...

Optimization of early cleaning and precommercial thinning methods in juvenile stand management of Norway

Abstract The purpose of this thesis was to develop the concept of cost-efficient Juvenile Stand Management (JSM) for planted Norway spruce (Picea abies L. Karst) stands. The principles of time based management were followed, by integrating regeneration activities as a cost-efficient value chain and by minimizing non-value-adding work with straightforward decision making based on forest management ...

Impacts of restoration of forestry-drained peatlands on nutrient and organic carbon exports and methane dynamics

In this study, the effects of restoration of forestry-drained peatlands on the nutrient and organic carbon exports and methane dynamics of the restored sites are explored. The study consists of four sub-studies. Two of the sub-studies are concerned with the effects on water quality and export of elements of restoration and were conducted on a catchment scale. One of the studies was conducted in th...

Dynamic variations in bark hydraulics - understanding whole tree processes and its linkage to bark hydraulic function and structure

A mature tree stem generally consists of a column of wood that is composed of a series of annual incremental layers and enclosed in a covering of bark. The dynamic variations of the bark are complex due to its structure and function: the thick outer-bark acts as a protective barrier against the abiotic and biotic environment; while the phloem is where sugar transport occurs. Much of the bark varia...

Developing laser scanning applications for mapping and monitoring single tree characteristics for the needs of urban forestry

Urban forests provide various ecosystem services. However, they also require fairly intensive management, which can be supported with up-to-date tree-level data. Until recently, the data have been collected using traditional field measurements. Laser scanning (LS) techniques provide efficient means for acquiring detailed three-dimensional (3D) data from the vegetation. The objective of this disser...

The role of terpenes in carbon and nitrogen cycling in boreal forest soils

Cycling of carbon (C) and nutrients plays pivotal role for functioning of every ecosystem. Biogeochemical cycles of carbon and nitrogen (N) are balanced by a network of inter-actions between plants, litter and soil chemistry, microbial communities, enzyme machinery and climate conditions. This thesis focuses on the role of terpenes in C and N transformations in boreal forest soils. Terpenes are ab...

Effect of waterlogging on boreal forest tree seedlings during dormancy and early growing season

Increasing rain in winter with climate change may expose boreal forests especially on drained peatlands to winter or spring waterlogging. Information about the response of main forest species on soil waterlogging is important for improving predictions of forest productivity and assessing the demand for ditch-network maintenance. In this study, the aim was to find out the physiological and growth r...

Selection of training areas for remote sensing-based forest above-ground biomass estimation

The aim of this work was to estimate forest above-ground biomass (AGB) - one of the fundamental parameters used in the forest inventory for measurement, reporting and verification (MRV) under the Reducing Emissions from Deforestation and Forest Degradation (REDD) and sustainable forest management (REDD+) mechanisms. In particular, this work examined the training area concept in a two-step approach...

Effects of climate, wood quality and fungal diversity on coarse wood decomposition of Scots pine

To increase the reliability of the present climate-carbon prediction models and to assess the resilience of forests for the adaptation and mitigation of climate change, it is essential to study the interactions between the various drivers of fungal wood decomposition. The study focuses on the independent and interactive effects of temperature, humidity, fungal diversity (species richness and assem...

Dead-wood-associated aphyllophoroid fungi: perspectives on the diversity, ecology and conservation biology of species and their habitats

This thesis examines the diversity and substrates of aphyllophoroid fungi with implications for their conservation biology. I focused on the distributional patterns of fungi on woody substrates, analyzed the diversity and indicators related to their substrates, and developed fungal monitoring schemes. The main results are: 1) A total of 303 aphyllophoroid fungi species were observed on my study s...

Changing institutions and consumer-driven development of forest products and services

The forest sector has been able to develop many new bio-based and sustainable products catered to business-to-business markets, but the sector still lacks a breakthrough in new forest products and services targeting consumer markets. This is due to higher prices of forest products compared to competing materials, such as concrete, steel, and plastics, but also due to a lack of new product and serv...
