Most countries in Europe have experienced loss of natural forest cover as land has been cleared for farming and other uses. Lack of timber and firewood resources over the last 350 years has been a driving force behind most afforestation work. This paper discusses the history and some major trends and drivers in the afforestation process in Western Norway.

De pågående masseangrep av Dendroctonus spp. startet mer eller mindre synkront i alle sentralamerikanske land sent i 1998 og tidlig i 1999; epidemien har hittil ødelagt flere hundre tusen hektar furuskog i Mexico, Belize, Guatemala, Honduras og Nicaragua, og i et mindre omfang El Salvador. Til tross for at landene er små, er naboer og har den samme insektfienden er samarbeid over landegrensene omtrent fraværende. Hele skadebildet og omfanget er også en direkte trusselmot det sterkt truete furu-eik økosystemet i regionen. Et felles regime for forvaltning av furuskogene og deres skadegjørere bør bli utviklet for fremtiden, men koordinert aksjon for å stoppe billene blir forhindret av forskjeller i styrke, kapasitetog mandat hos de forvaltende institusjoner i hvert land. Likevel, omfanget og alvoret i den pågående epidemien har resultert i flere bilaterale og regionale initiativer, og lagt grunnen for formelle, langvarige regionale samarbeidsprogrammer i forvaltningen av denne viktige biologiske ressursen.

Welfare conditions for free ranging animals are in several respects superior to many indoor systems. However, attempts to improve protection of endangered predator species, in particular brown bear (Ursus arctos), wolves (Canis lupus), lynx, wolverine (Gulo gulo), and the golden eagle (Aquila chrysaëtos) during the late 1980s and the 1990s have lead to increasing sheep losses on Norwegian ranges. Predators are causing considerably more pain than slaughtering, a longer time of suffering and sometimes leave surviving animals wounded with scratches or thorn up udders etc. Lambs may be chased away from the mothers. Mitigating measures such as replacing outfield pastures with fenced farmland, sending animals to secure areas or sheep milk production are gradually being introduced. The paper discusses the animal welfare implications induced by the changes currently taking place in the Norwegian sheep industry.
