Sagens resultat:regelgrundlaget for proces i skelforretningssager

I artiklen redegøres for procesreglerne, der danner baggrund for sagens resultat ved skelforretninger, uanset om sagens resultat er parternes tiltrædelse, landinspektørens afgørelse, retsforlig, dom eller sagens ugyldighed som følge af matrikelmyndighedens nægtelse af notering af sagen. Det slås fast, at sagens lovlige resultat alene kan være landinspektørens skøn af den rette ejendomsgrænse. Med et konfliktforebyggendeperspektiv problematiseres det, at reglerne for erklæringen, hvormed parternes tiltræder skellet er utilstrækkelige

Crown structure, growth, and drought tolerance of true service tree (Sorbus domestica L.) in forests and urban environments

True service tree (Sorbus domestica L.) is a rare native species of Central Europe. It grows well in dry and warm environments and may consequently be well adapted to the expected future climate further north. It is considered a potentially suitable species for climate change adaptation in forests and urban environments. In this study, we used total tree height, stem diameter, and crown dimensions of true service trees in Germany, southern Scandinavia, northern Italy, and Slovakia to determine the species' allometric relationships and space re-quirements. Additionally, we used tree cores from Germany and Slovakia and stem discs of a true service tree in Copenhagen to study growth patterns and drought stress response. Throughout, we compared to oak (Quercus robur L. and Quercus petraea (Matt.) Liebl.), as common and well-studied species. Our results indicated that true service tree and the two oak species have similar growth patterns and space requirements. True service tree and oak both had a fast growth in their youth, followed by a gradual reduction at later stages. The crown projection area of true service tree was similarly influenced by competitors as that of oak, indicating a similar sensitivity towards competition. Likewise, we identified similarities in growth response to drought and, hence, drought tolerance. Due to their comparable growth pattern and drought tolerance, we hypothesise that oak, in many regards, can be used as a model species for the management of true service tree

The history of Fagus sylvatica at its northern limit in Vendsyssel, Denmark

Pollen, plant macrofossils and charcoal analyses were used to study tree diversity, fire history and forest disturbance over the past c. 3500 years at threeforest remnant sites in Vendsyssel, northern Denmark. All locations had a more diverse tree composition in the past including abundant Alnus, Betula,Corylus, Pinus, Quercus, Salix, Tilia and Ulmus. The changes in tree diversity through time can be attributed to a combination of factors including climatechange, burning linked to shifting cultivation, grazing and felling. The balance between arboreal and non-arboreal pollen was already being influenced byhuman activities in the late Bronze Age c. 3000 years ago. The high pollen abundance values recorded for Tilia pre-2000 years ago are exceptional ascompared to later periods at these sites. At one location, the transition from Tilia to Fagus indicated that Tilia prevailed until c. 1300 years ago. Subsequentperiods of forest clearance, with charcoal and cereal cultivation, initially including Hordeum and subsequently also Secale, were recorded. There was pollenevidence for grazing followed by shrub regeneration including Calluna, Erica, Juniperus and herbaceous taxa, and following that, a forest recovery of mainlyFagus, Picea and Pinus. This recovery is also recorded in historical forest records from 1880 CE onwards, emphasising the dominant role of plantationschemes. Results are placed in a wider framework of other sites in Denmark and southern Scandinavia, which have also documented a reduction oftree diversity and forest cover over the same period. The evidence from the long-term record is used to draw conclusions to assist forest restorationprogrammes

Procesvalg, rekvisition og forberedelse:regelgrundlaget for proces før skelforretningen

I artiklen redegøres for reglerne, der ligger til grund for processen før skelforret-ningen. Begrænsningen i parternes adgang til domstolene problematiseres. Det konstateres, at retsvirkning af henholdsvis rekvisition og indkaldelse ikke er fuldt afklarede. Der argumenteres endvidere for, at kravene til oplysning af sagens parter er utilstrækkelige

Storfrugtet røn: en ny træart til skovdyrkning, frugtavl eller bare en gearet investering?

Service tree (Sorbus domestica L.) is almost unknown in Denmark, but may be interesting in a future warmer climate. The paper includes an introduction to the species' ecology, diseases, cultivation and products. Service tree has a number of good properties, but can be difficult to establish. It is recommended only to plant service tree on a small scale, until effective means against stem cankers have been identified. On the suitability of service tree for silviculture in Denmark: Service tree is drought tolerant and thrives well in a climate that is slightly warmer than at present in Denmark. However, service tree can be somewhat difficult to establish and young trees are prone to stem cankers that may potentially kill the tree. In 2002 we planted some service trees of unknown origin in northern Denmark. They were planted in different types of already established, mixed forest stands. The area had previously been stocked with an apple orchard. The rate of survival was high although none of the trees were sprayed with sulphur or copper. Now, all the service trees suffer more or less from stem cankers and most of them do not thrive well. In 2013 we raised some seedlings of Modra origin (Figure 1). Almost all seeds germinated, and the seedlings grew 34‐92 cm tall in the first growing season (average height = 57 cm). We consequently consider it easy to produce nursery plants. So far, our experience is insufficient to judge the long‐term prospects for service tree as a forest crop tree in Denmark. However, old and large trees in good growth and without diseases testify that service tree can thrive and remain healthy. In a coming article we will present an overview of some of the trees that we know. In our opinion, the fruits and the spectacularly beautiful autumn foliage are sufficient reasons for planting some service trees in the forest. We recommend small‐scale plantings until effective means against stem cankers have been identified
