The global trend for biological diversity is negative and that goes also for species living in the forest. This study is investigating the urban forest Hallaholm in Åtvidaberg, Östergötland, which is owned by the municipality. The study concludes the different habitat types which are present in different parts of the forest. The parts are assessed based on the presence of Fomitiporia robusta, Porodaedalea pini and of structures such as dead trees, lichen on trees, poroid fungi and hollow trees. There is also an assessment of the importance of the different habitat types for the green infrastructure in the region. The habitat types are mainly deciduous and broad-leaved deciduous forest, pine, spruce and grassland. This study shows that the highest ecological values and the greatest importance for green infrastructure is found among deciduous forest, broad-leaved deciduous forest and grassland, also partly among pine and the lowest values are found among spruce. New records of Fomitiporia robusta and Porodaedalea pini were noted. Measures on how to increase the biological diversity and the importance of the forest for recreational activities are suggested based on the results and on the collected knowledge of the forest.

Natura 2000 is part of the European Union: s framework to protect and preserve biological diversity. Natura 2000- areas are by the goverment appointed to areas of national interest for preserving nature. Also wind power stations are appointed as of national interest and the reason for this is the goverments goal to get energy from reneweble energysources. This essay describes when both these intrests conflict eachother when it comes to building wind power stations within Natura 2000- areas. The main focus of this essay is a casestudy of two cases from two different counties, Dalarna- and Norrbotten county, where applications have been made to build wind power stations within existing Natura 2000- ares, both cases have reached the court dealing with enviromental issues. In Dalarna county the court dealing with enviromental issues said no to the application and in Norrbotten the court said yes but in both cases simular factors seem to have been determining the outcome. For instance seem the Natura 2000 protection to be of minor consideration and rather what kind of habitats and biotopes that could be damaged in case of putting up a wind power station park and how these habitats and biotopes would be affected seems to have been the main focus. In Dalarna county the area is consisting to onehundered percent of the priority biotope western taiga and in Norrbotten the area holds different types of biotopes of which some are counted as prioritied biotopes. The amount of energy produced have also been in focus when judgement have been made in the two cases. The fact that both wind power stations and Natura 2000 are of national interest seem to have been of no consideration and the conflict between these two interests does not seem to have been in focus in the two cases.
Grau, Marlen, e Emelie Lindskog. "Biotopinventering av Ögärdet i Hylte kommun". Thesis, Högskolan i Halmstad, Akademin för ekonomi, teknik och naturvetenskap, 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:hh:diva-42642.
Ögärdet skog ligger öster om Mjälahult i Hylte kommun. Öster om skogen ligger sjön St. Allgunnen, vilken ingår i Nissans huvudavrinningsområde och där man bland annat kan hitta abborre, braxen, gädda, sik och gös. Den inventerade skogen är en ädellövskog som består av bok och ek, med inslag av björk, rönn, hassel, gran och tall. Det finns tecken på att området förr har använts som betesskog med gamla stenmurar som inhägnar området. Det finns även tydliga tecken på en gammal väg som korsar den nuvarande grusvägen och in i skogen. Området består av mycket mossbeklädda stenar, stenrösen, död ved, skägglavar och spår från större hackspett. Det huvudsakliga syftet med denna biotopinventering är att värdera biotoper som är utav värde för biologisk mångfald, samt för att utveckla ett skydd för dessa biotoper. Arbetet är utfört enligt SIS standard (SS 199000:2014), med tillägg värdeelement. Under inventeringen identifierades fyra olika biotoper – blandskog, strandskog, blandsumpskog och ädellövskog. Två biotoper identifierades med ett påtagligt biotopvärde, vilka var ädellövskog och blandsumpskog. Den tredje biotopen som identifierades var strandskog, vilken bedömdes ha ett visst biotopvärde. Delar av området identifierades även till biotopen blandskog, vilka bedömdes ha ett obetydligt biotopvärde. De värdeelement som påträffades täcker stora ytor av skogen och har ett högt naturvärde, vilket ger upphov till ett intresse att bevara och skydda skogen långsiktigt med förutsättning att den i framtiden kan gynna biologisk mångfald.
Barrhök, Johan. "Från ett nödvändigt ont, till en naturtyp värd att bevara - en studie av ljungheden i Sandsjöbacka och Grönabur/From a necessary evil to a nature type worth protect - a studie of the Calluna heath of Sandsjöbacka & Grönabur". Thesis, Kristianstad University College, Department of Mathematics and Science, 2005. http://urn.kb.se/resolve?urn=urn:nbn:se:hkr:diva-3407.
In the middle of the 19th century was Calluna heath the major nature type in Halland, but the remaining parts today is only 1 500 hectares which is a 99 % decrease of the Calluna heath mainly due to an increase in forest plantations and arable fields. I have made a quantitative study how the Calluna heath of Grönabur & Sandsjöbacka has changed between 1841 and 2005 and why it didn’t disappear in the same manner, as it did in other parts of Halland.
The studying of original sources as historical maps, literature and by doing field visits has been significant for the final result. The main reason for the different development of the Calluna heath in the investigation area (69 % decrease), compare to elsewhere in Halland, is the establishment and management of a nature reserve.
Korall, Elin. "Är Sveriges områdesskydd klimatanpassat? : En geografisk analys över hur mycket av Sveriges skyddade natur som påverkas vid en havsnivåhöjning". Thesis, Högskolan i Halmstad, Akademin för ekonomi, teknik och naturvetenskap, 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:hh:diva-42775.
Due to climate change and global warming, there is an ongoing sea level rise. IPCC has published four climate scenarios that show the projected changes in climate until the year 2100. The global sea levels are estimated to rise between 28 and 98 cm, which will result in great consequences for coastal landscape and protected nature. This study is the first in Sweden to analyze which consequences a sea level rise will have on protected nature in Sweden. A geographical analysis has been made of how much of the Swedish nature reserves and Natura 2000-habitat types that are going to be covered by the sea in three of the climate scenarios. The sea will cover more than 5% of the total area in 34-102 nature reserves depending on which scenario takes place, which means a loss of 750-4640 hectares. More than 5% of 14-15 Natura 2000-habitat types in Sweden will be covered by the sea. Four of the habitat types that are most affected in the worst scenario are; Annual vegetation of drift lines (46%), Salicornia and other annuals colonizing mud and sand (85%), Atlantic salt meadows (42%) and Boreal Baltic coastal meadows (44%). Recent research has shown that habitat loss due to climate change and sea level rise can be avoided if species and habitats are allowed to move inland, and that management of surrounding areas are of high importance in conservation biology. It is therefore essential to use conservation strategies that are adapted to sea level rise.
