Abstract
The coastal heath region along the western coast of Norway, dominated by Calluna vulgaris, is undergoing rapid change. Vegetation changes are caused by changes in management, including reduced frequency or abandonment of periodic heath burning and reduced cutting and grazing. The islands of Froan, in the outermost part of Sør-Trøndelag County in mid-western Norway, are dominated by coastal heath in a state of recession due to reduced traditional land use. The coastal heath is acknowledged as vulnerable and valuable by national environmental authorities, and local landscape management is supported by different national subsidies. The authors mapped the vegetation on Froan and used rule-based GIS-modelling to predict the relative potential for future vegetation changes. The model was based on a range of map layers, including management themes such as history of heath burning and peat removal, current practices of sheep grazing, and also themes derived from the vegetation map, such as soil nutrients, soil moisture and present management status. The resulting model output provides relative probabilities of future changes under different land-use scenarios, and highlights where management efforts should be focused in order to maintain the traditional landscape character.
Abstract
The conference «Mapping and Monitoring of Nordic Vegetation and Landscapes» took place in Hveragerði, Iceland from the 16th to the 18th of September 2009. The 105 participants from 15 countries contributed with 50 oral presentations and 19 posters. This special edition of «Viten», published by the Norwegian Forest and Landscape Institute, presents the conference proceedings, containing 32 articles and 13 posters. We wish to thank the participants for their contributions to both the conference and this report! .....

Our primary mission is to create an office in Juba with the necessary knowledge, computer equipment, GIS-software and the necessary satellite images. The office and its employees are going to be the independent land cover mapping authority in Southern Sudan. 4 persons from Norwegian Forest and Landscape institute had totally 11 stays in Juba in 2008. Our main task this year was to establish the office with equipment and expertise. The competence of the employees proved to vary a lot and in many cases to be inadequate. We started the transfer of knowledge on a very basic and simple level. The first year was celebrated by making a simple map showing the location of the known Forest Reserves in Southern Sudan at that time. The office had produced their first official map.

The primary mission of the project is to create a Land Resource Survey and Information Centre in Juba with the necessary knowledge, computer equipment, GIS-software and the satellite images to map and monitor land resources. The office and its employees will be the independent land cover mapping authority in Southern Sudan. The Norwegian role is to support capacity building in the institution. The actual survey, mapping and monitoring activities should be carried out by the institution itself. The project was a continuation of work started in 2008. In 2009, more advanced training in GPS, digital mapping, remote sensing and production was carried out and a forest inventory was started. The office was upgraded with an installation of a battery backup system witch provide power enough to run the office for 3-5 hours in case of no electricity. A network of contacts with other relevant activities in South-Sudan was also established. The first land cover map produced by the office, covering the area between Yei and Juba, was produced based on interpretation in satellite images and verification in the field. The map “Forest reserves in Sothern Sudan” was upgraded to show the known forest reserves included as polygons with their actual shape and size.
Abstract
AR18×18 is an area frame survey of land resources in Norway, methodologically linked to the Lucas survey carried out by Eurostat (Eurostat 2003). The purpose of the survey is to establish an unbiased and accurate land cover and land use statistic providing a description of the state of land resources in Norway. The survey will also provide a baseline for future reports regarding changes in land resources – a national land resource accounting system. AR18×18 is based on Lucas (Land use/cover agricultural survey), a European area frame survey carried out in the EU countries by Eurostat. The sampling units of Lucas are points located on the intersections of an 18 × 18 kilometer grid mesh throughout Europe. Each of these points is the centre of a Primary Statistical Unit (PSU) of 1500 × 600 meters. The Lucas survey is carried out on ten sample points scattered within each PSU. The Norwegian modification of Lucas is to add a land cover survey of the whole PSU following the Norwegian system for vegetation and land cover mapping at intermediate scale (1: 20,000). [...]

The forest limits of south-east Norway have expanded to higher altitudes. Two main processes are believed to cause these changes; re-growth after abandonment of human utilisation and recent climate changes. This article aim at separating the effects of these two processes on the upper forest limits and recent forest expansion. The results show that raised forest limits and forest range expansion often attributed to recent climate change is rather the product of re-growth, a process that was climatically retarded from 1959 to 1995. From 1995 to 2006, the data indicate a preliminary effect of climate change escalating the re-growth and probably pushing the future forest limits to higher altitudes.

Abstract
AR18×18 is an area frame survey of land resources in Norway, methodologically linked to the Lucas survey carried out by Eurostat. The method has been adapted to Norwegian conditions. Data accessible through existing mapping systems and public registers are not collected. On the other hand, the survey is strengthened with a land cover mapping component. The purpose of the survey is to establish an unbiased and accurate land cover and land use statistic providing a description of the state of land resources in Norway. The study will also provide a baseline for future reports regarding changes in land resources

This report presents all livestock production systems in Norway that significantly contribute to the country’s food and agricultural production. It describes the regulatory framework for Norwegian agriculture and aquaculture, as well as characteristics of the country’s production conditions and breeding work. The report discusses national expertise in the field of farm animal genetic resources and future developments regarding the country’s use of these resources. Furthermore, the report presents the conservation of Norway’s historical breeds with small populations. It concludes by making recommendations on which areas both Norway and the Nordic countries should emphasize regarding R&D activities and capacity building..... Genetic resource centre.
