A lot of habitats have declined or disappeared as the old cultural landscape changed to the modern agricultural landscape of today. Places such as power line corridors, racing tracks, gravel pits and military training sites have become refuges for many species associated with the old cultural landscape. These sites have been exposed to ecological disturbances that create the same type of habitats that were found in the old cultural landscape. The military training sites in Sweden has an impressive diversity of species. Disturbances from the military exercises have created habitats that are important for a wide range of species. The purpose of this thesis is to study some of the ecological disturbances occurring in the military training sites of the Swedish Armed Forces and examine how they affect different types of habitats. The thesis explains through litterateur and field studies the reason to the rich biodiversity often found at military training sites. The training sites and firing ranges of Skövde garrison were used as an example to show how the disturbances affect the environment. The study shows that military exercises (e.g. with combat vehicles) creates habitats that previously existed in the old cultural landscape. Soil damage from combat vehicles benefits insects and creates pools for amphibians. Damages on trees create snags and woody debris which favors a large amount of species. The military exercises also keep an open landscape.

En ökad exploatering och markanvändning har under det senaste århundradet kraftigt reducerat odlingslandskapets variationsrikedom och biodiversitet, vilket medfört drastiskt förändrade livsvillkor för många arter på jorden. Forskning visar att militära övnings- och skjutfält har kommit att bli en tillflyktsort för många hotade arter, dels  på grund av att de blivit förskonade från annan markexploatering och dels för att de militära störningarna visat sig gynna många arter.   Denna studie har som syfte  att utreda vilka störningsregimer som historiskt gynnat biodiversiteten på Torhamns övnings- och skjutfält  i sydöstra Blekinge. I denna undersökning analyseras biodiversitet på landskaps- och artnivå. Tidigare resultat från pollenanalyser ca en mil norr om undersökningsområdet visar att regionen har präglats av markanvändningsformerna bete och slåtter under flera tusen år och att den floristiska diversiteten varit hög sedan tidig järnålder. Den militära verksamhet som bedrivits på Torhamns udde under de senaste 100 åren har med stor sannolikhet bidragit till att bevara de unika naturvärden som finns där idag. En viktig slutsats som kunnat dras av denna studie är att biologisk mångfald förändras över tiden och att det finns en tydlig koppling till markanvändningsförändringar. Det är med kunskap om den historiska markanvändningen som det går att förklara varför flora och fauna ser ut som den gör idag och för att kunna främja biologisk mångfald på militära övnings- och skjutfält, är det därför av största vikt, att ha ett paleoekologiskt perspektiv vid upprättandet av bevarandemål och hållbara handlingsplaner. / The increasing exploitation of land and the changes in land use over the last few hundred years has led to a marked reduction in the biodiversity of the landscape. Species populations have diminished in number or even gone locally extinct due to habitat loss. Research has shown that military training areas have become a refuge for many endangered species, partly due to the fact that these areas have been spared from exploitation of the land and partly due to the fact that these species have thrived as a result of the disturbance of habitat caused by military activity.   This study aims to clarify which types of disturbance have had a positive effect on the biodiversity of Torhamns udde in South East Blekinge through history. In this investigation biodiversity is analyzed at the landscape and species levels. Earlier results from a pollen analysis north of the study area show that the region has been affected by land use over a period of several thousand years. The military activity that has taken place in the area over the last hundred years, has contributed to the preservation of the unique natural environment that exists there today. An important conclusion from this study is that changes in biodiversity are strongly connected with changes in land use. The present composition in the flora and fauna may thus largely be explained by the historical land use. In order to positively influence the biodiversity of a military training area, it is important to have a palaeoecological approach, when conservation and management plans are being set up.

This thesis is focused on the importance of large herbivore pasture for arthropod communities in temperate steppe. The study site was located in former military training area Milovice, regional biodiversity hotspot, where wild horses and aurochs were introduced as an active measure aimed at biodiversity conservation. Main goals of proposed study were to assess the role of vegetation structure and presence of grazing on beetle species composition in two trap heights, to examine suitability of flight intercept traps for monitoring arthropods of open habitats, to set the continuous arthropod monitoring program on the site and to propose a suitable model groups to assess habitat changes.
