High boreal forest multifunctionality requires continuous cover forestry as a dominant management

2021

Intensive extraction of forest resources lowers biodiversity and endangers the functioning of forest ecosystems. As such, alternative management regimes have emerged, aspiring to promote forest biodiversity and nature protection in managed forests. Among them, continuous cover forestry, (i.e. selective logging), has received considerable attention and is being promoted by some researchers and NGOs. Yet, the full consequences of banning clear-cuts (i.e. rotation forestry) and replacing it entirely with continuous cover forest remains uncertain. We explore how restricting forest management alternatives (either rotation forestry or continuous cover forestry) will affect landscape-scale forest …

Seventy-year changes in tree species composition and tree ages in state-owned forests in Latvia

2011

Abstract During the last 100 years, forest management in Latvia has gradually become more and more focused on industrial logging, which can be expected to have affected the tree species composition and age distribution across the landscape. These changes need to be considered in forest management and conservation of biological diversity. The aim of the study was to use forest records to reconstruct the tree species composition and age distribution in the North Vidzeme Biosphere Reserve in northern Latvia for the period, 1929–1941. These data were compared to a data-set from 2008, to determine the changes that transpired during a period of intensification of forest management. The silvicultu…

Dry years and their relationship to crop production in Sri Lanka

1981

Drought is a distinct agroclimatological hazard with far reaching consequences upon crop production. Among them, famines are regarded the most serious effects of climatological drought. Although there is no doubt about the principally valid relationship between drought and production losses it seems more problematic how this relationship can be proved statistically. In this paper annual rainfall data and production figures of the three major crops of Sri Lanka, rice (paddy), tea and rubber, are correlated, but only partially a true relationship between dry years and production losses could be observed. Reason for this may be the moderate degree of annual drought. From the results shown, the…

Persepsi Masyarakat Lokal Terhadap Pengembangan Hutan Mangrove Sebagai Kawasan Ekowisata Di Kampung Ruar Distrik Biak Timur Kabupaten Biak Numfor

2021

The mangrove forest area of ​​Kampung Ruar, East Biak District, is an area that has traditionally been a place for fishing and lime-making efforts by the community who have been hereditary. This condition raises questions from various parties whether this location is suitable to be developed as a mangrove ecotourism destination. Development of Mangrove Ecotourism by the Papua Provincial Forestry Service as a tourist attraction by utilizing local natural potential and supporting tourism policies in Biak Numfor Regency. This study aims to see the socio-cultural conditions of local communities in the Mangrove Forest Area of ​​Kampung Ruar, Biak Timur District, Biak Numfor Regency as an ecotour…

Monsoon and land use in Sri Lanka

1979

Agricultural land use in Sri Lanka roughly shows a division of the island in two major parts, according to the climatic division into the Wet and Dry Zones. Therefore, it is the ultimate, most important question for agricultural land use in Sri Lanka whether the seasonal occurrence of a distinct dry season, which is characteristic of the Dry Zone, is also the most delimiting factor for land use or not. It seems true, in fact, that the long SW monsoonal dry season in the Dry Zone is the major fact for a large-scale division of Sri Lanka according to the crops under cultivation and the cropping systems. Paddy (rice) and tea are the leading crops in the Dry as well as Wet Zone. They are at the…

Suitability of a native South African shrub as pot plant

2006

Leonotis leonurus (L.) Br. Pubesc., also known as “lion’s ear” is a perennial shrub belonging to the Labiatae family and native to South Africa. The name of the genus derives from the Greek words leon (lion) and otòs (ear). The esthetic ornamental value of its bright orange inflorescence and its adaptation to a wide range of conditions have led a research to evaluate the suitability of L. leonurus as pot plant. Pot plants from one year rooted cuttings were grown in the Northern coast of Sicily; at the end of December, plants were pruned to 30 cm length and then moved to an unheated plastic greenhouse. Flowering started in April under protected cultivation and continued throughout the summer…
