A high forest coverage rate contributed to the better air quality, increasing or preserving the forested areas would help mitigate the air pollution.
A high forest fire season of two to three years is regularly observed each decade in Mexican forests.
Nonetheless, there is abundant evidence for other forests that selection systems can maintain a high forest cover, complex vertical layering and balanced/regulated structures while providing income through timber sales at regular intervals on a sustainable basis (e.g. O'Hara 2014; Schütz et al. 2012; Pukkala and Gadow 2012; Gronewold et al. 2010; O'Hara et al. 2007; Keeton 2006; Bagnaresi 2002).
The second wild cherry stand (56 trees on about 5 hectares) near Roringen is about 70 years old and located in a protection area that is treated as a high-forest system.
This landscape mosaic is characterized by a much higher forest edge-to-interior ratio than in closed boreal forests.
This was caused by 1) a much lower baseline forest area loss rate in general for the reduction in the North (−1.76%), compared to −6.64% in the West on average; and 2) a much higher forest carbon density and growth rate in the Pacific Northwest states and northern California[29, 30] where unprotected forestlands were concentrated (Figure 1).

The final results could be considered overvalued, owing to domination of respondents from the middle and northern parts of Slovakia, which have higher forest coverage and a higher rate of forest visitors for recreational purposes, which can be anticipated in highly forested regions.
In a month or so, the harvest finished, it will be a waist-high forest of ferns.
Carbon density varied from 156±36 Mg C ha−1 in a low-stocked forest to 427±11 Mg C ha−1 in a high-stocked forest, corresponding to a highly degraded forest harvested by conventional logging and to a pristine forest, respectively.
