Att restaurera forna tiders beståndsstruktur : ett exempel från Jämtgaveln
In Sweden today so-called "prescribed nature conservation burning" is performed due to the change in silvicultural law, certification and an increased knowledge regarding the field of fire in the forest landscape. The aim is to re-create structures and qualities made by the fire regimes of the past, though on a much smaller geographical scale. The structures and qualities to be re-created are for example broad leaf stands, trees with large diameter, heterogeneous stands regarding variables such as age and diameter. If we increase our knowledge of the constitution of forests characterized by fire, then we will be able to set goals for what achievements to reach both on landscape scale and stand scale.
The aim of this paper is to try to describe how a stand from the past was composed regarding mainly the spatial arrangement and compare it with the stand of today in the same place. This to be done by using relict material, that is stumps and dead standing trees.
EU ger eko bland korna - från uppbundet till lösdrift :
ABSTRACT
For hundreds of years there has been a tradition with tethered dairy cows in Sweden. The last
decades the old fashioned way to hold cows have been questioned and the number of dairy
cows in loose housing has been increasing. Last year (2004) 19 percent in total of all farms
with milk production in Sweden had their cows in loose housing. Because of EU-legislation
concerning all organic production no farms are allowed to build tie stalls any more and after
2010 all organic dairy cows are supposed to live in loose-housing systems.
The aim of the thesis was mainly to find out the number of farms with tethered organic dairy
cows and if they will continue after the year 2010. Furthermore the purpose was to study if
there are any regional differences, how countries similar to Sweden interpret the EU-decision
about tethered cows and differences in buildings between organic and conventional farms and
the reasons to them.
