Furthermore, they consider that the introduction of non-native tree species does not correlate with nature conservation aims, especially regarding the maintenance of open stands (Germany: policy group).
Thus, manipulation of stand structure and the maintenance of a variety of stand structures across the landscape are important strategies for managing the diversity of ground vegetation.
These strategies may include the maintenance and restoration of stand structures, enhancement of tree vigor, regeneration of healthy and resistant species, and timber extraction.
The maintenance of these attributes in managed stands is essential for sustaining forest biodiversity as has been illustrated, for example, in boreal ecosystems (Bauhus et al. 2009 and citations within).
Hence, the maintenance of the highest C-density stands in the landscape, and potentially that largest landscape level C-stocks among Tasmania's wet forests ironically requires the periodic killing of all, or part, of the large C-dense eucalypt overstory by intense wildfire to allow these large eucalypts to regenerate and persist on these sites.
The MOBILIZE Boston Study MBSS), which stands for "Maintenance of Balance, Independent Living, Intellect, and Zest in the Elderly of Boston" is a major new cohort study, part of the Hebrew Rehabilitation Center/Harvard Research Nursing Home Program Project.
Establishment and maintenance of strong capital base.
Mature, unevenly structured forests might occur as a result of sustainable forest management, aimed at preserving the continuity of old stands and the maintenance of diverse age and species' structure, providing suitable habitat condition for the species.
This breakdown maintenance mentality stands in direct opposition to the target of high productivity.
The forests of Durango have been managed by local communities for more than 70 years, mainly using selective harvesting, for sustainable timber production but also for the maintenance of biological diversity and uneven-aged stand structures.
