D1.1 Database and models regarding soil type specific bearing capacity and hydraulic transfer properties
This report focuses on material and method descriptions for a number of individual studies that are done within WP1, while all the models developed within EFFORTE will be published later. The report includes two sections: 1. Database set up in France on 12 plots to adapt an existing soil type specific hydrological model named PASTIS to forest conditions and the different calibration and validation steps of the model that will be delivered in June 2019, and 2. Material, methods and models developed in Finland of “moisture content – soil strength relationship”. As a manuscript describing the experiments and models has been submitted to a scientific journal, all models will be published later. D1.1 will be updated in July 2019.

D2.1 New solutions for seedling supply chain and enhancement in planting devices; technical report on development and innovations
This deliverable dives into planting systems supporting efficient regeneration. Two existing plant delivery concepts are studied and evaluated for developing new delivery systems suitable for mechanical planting. The study is done in Sweden where there is only one concept of planting machine in operational forestry – at the moment both manual and mechanical planting concepts are time- and cost-consuming.

D2.3 Silvicultural feasibility of new early PCT methods
Young stand management can traditionally be separated into two different treatments: early pre-commercial thinning (PCT), and ordinary PCT. When early PCT is done, usually second PCT needs to be done a few years later because of sprouting. The efficiency can be enhanced by reducing the costs or minimizing the number of operations.  Uprooting devices and biological treatments can give solutions to the problems of PCT. The aim of this study is to verify the silvicultural efficiency of these two methods for early PCT and to evaluate the cost-efficiency of these young stand management operations.

D2.4 Advanced biomass thinning
This report presents new concepts of mechanized boom-corridor thinning (BCT) of dense forest stands with small trees focusing on productivity and functionality of the techniques, and to model and simulate optimized BCT and bundling technique. Modelled systems and concepts are still hypothetical and their performance and costs are uncertain, but the potential is showing clearly. Check the whole deliverable to learn more!

D4.2 Review of additional accessories, equipment and methods for harvesters, forwarders and skidders
There are several ways to protect the soil and cause as little damage as possible when doing forest operations. This deliverable presents how harvester residuals, different tyres and tyre pressures, track chains and extra wheels, different types of machines, bridges and protective mats and sorters and flexible load frames affect the ground. Some of the alternatives focus on increasing productivity and thus decreasing the number of passes, which protects the soil, and some focus mainly on soil protection, such as harvester residuals, bridges and protective mats. To be cost-effective, tailored solutions to different areas and needs are needed.
