The Impact of Logging on Species Richness and Turnover of Field Layer Species in Swedish Boreal Forests

Autor: Per Milberg, Johan Bergstedt

Publikováno v: The Open Environmental & Biological Monitoring Journal. 1:48-57

On two occasions, with a 10- or 11-year interval, species occurring in 650 plots (100 m2) in boreal production forests in Sweden were recorded within a monitoring program. During this interval, ma ...

Publikováno v: Journal of Vegetation Science. 19:633-644

Question: Detecting species presence in vegetation and making visual assessment of abundances involve a certain amount of skill, and therefore subjectivity. We evaluated the magnitude of the error in data, and its consequences for evaluating temporal

Understanding the responses of tundra systemsto global change has global implications. Most tundraregions lack sustained environmental monitoring and oneof the only ways to document multi-decadal change is toresample historic research sites. The Inte
