An indigenous species coastal planting trial was established at Ohiwa Spit, eastern Bay of Plenty in mid-2005 by the the Ohiwa Beach Coast Care group, Whakatohea Trust, Environment Bay of Plenty and Opotiki District Council. The aim of the trial was to evaluate the performance of a range of local indigenous ground cover and shrub species planted within three demarcated zones on a relatively sta...
The impact of invasion on diversity varies widely and remains elusive. Despite the considerable attempts to understand mechanisms of biological invasion, it is largely unknown whether some communities' characteristics promote biological invasion, or whether some inherent characteristics of invaders enable them to invade other communities. Our aims were to assess the impact of one of the massive...
The aim of present study was comparison of plant diversity in managed and control compartments of Jamand district in Noshahr (Mazandaran province). Random-systematic sampling method with network dimension of 100×200 m was used to locate samples. Sampling plot area was 400 m2 to survey woody species and 100 m2 plots was set up to herbaceous species (in the center of main plots). At each sample p...
Although most temperate forests are actively managed for timber production, few data exist regarding the long-term effects of forest management on understory plant communities. We investigated the responses of understory communities to a factorial combination of silvicultural-thinning and nutrient-addition treatments maintained for 12–16 yr in a set of 21–27 yr old Douglas-fir (Pseudotsuga menz...
The impacts of introduced or overabundant large herbivores are a concern for the conservation of forest plant communities and the sustainability of ecosystem function. White-tailed deer (Odocoileus virginianus) are considered ecologically overabundant in much of North America. Previous work suggests that impacts of deer overabundance are broadly negative and are consequently degrading forests a...
