When using multiple imputation, users often want to know how many imputations they need. An old answer is that 2–10 usually suffice, but this recommendation only addresses the efficienc...
Exotic conifers can provide significant ecosystem services, but in some environments, they have become invasive and threaten indigenous ecosystems. In New Zealand, this phenomenon is of considerable concern as the area occupied by exotic trees large increasing rapidly. Remote sensing methods offer a potential means identifying monitoring land infested these trees, enabling managers to efficiently allocate resources for their control. study, we sought develop remote detection namely Pinus...
Abstract Background Natural forests cover approximately 29% of New Zealand’s landmass and represent a large terrestrial carbon pool. In 2002 Zealand implemented its first representative plot-based natural forest inventory to assess stocks stock changes in these mostly undisturbed old-growth forests. Although previous studies have provided estimates biomass or stocks, were either not fully lacked data from important pools such as dead wood (coarse woody debris). The current analysis provides...
The spread of exotic conifers from commercial plantation forests has significant economic and ecological implications. Accurate methods for invasive conifer detection are required to enable monitoring guide control. In this research, we combined spectral information aerial imagery with data airborne laser scanning (ALS) develop identify using remotely-sensed data. We examined the effect ALS pulse density height threshold training dataset on classification accuracy. results showed that adding...
To meet international greenhouse gas reporting obligations, New Zealand must report on carbon stocks in forests established after 1989 (post-1989 forest). Although predominately comprised of planted forest, post-1989 forest also contains a component natural vegetation amounting to less than 10% by area. undertook national inventory this stratum provide estimates and stock change woody species over the first commitment period (2008–2012) Kyoto Protocol. Plots were installed 4-km grid, basal...
Global climate change and shift towards a bio-economy has heightened the need to design sustainable forestry systems that balance economic, environmental social benefits. In New Zealand, production forests are dominated by planted Pinus radiata, which makes up 90% of forest area. There is very little data driven evidence in Zealand support diversifying across range tree species what timber non-timber benefits may be gained Zealand's forests. The Forest Trial Series (NFTS) was designed...
Abstract Plant invasions are a widespread and recurring phenomenon that cause significant economic environmental damage. Invasive alien conifers weeds not only costly to manage, but consistently reinvade after management efforts. Understanding how many seeds survive germinate is key part in understanding the weed life cycle puzzle. Here we investigated contribution seed predators have on reducing invasive conifer survival across both invaded uninvaded habitats Aotearoa New Zealand. We...

Abstract Background Reducing net greenhouse gas emissions through conserving existing forest carbon stocks and encouraging additional uptake of in new forests have become important climate change mitigation tools. The contribution harvested wood products (HWPs) to increasing has been recognised approaches quantifying this pool developed. In New Zealand, harvesting more than doubled since 1990 while log exports increased by a factor 11 due past afforestation comparatively little expansion...
Abstract Plot‐based data collection is an important component of quantitative ecological research and widely used. Some the most extensive plot‐networks can be found in country‐wide forest inventories, which provide critical information about state ecosystems. While sampling designs for inventories have been well studied, plot design installation has received less attention. The New Zealand National Forest Inventory natural uses a nested with 0.126 ha circular superimposed concentrically on...
